Forest Type Influences Population Densities of Nocturnal Lemurs in Manompana,Northeastern Madagascar

Forest loss, fragmentation, and anthropization threaten the survival of forest species all over the world. Shifting agriculture is one of these threatening processes in Madagascar. However, when its cycle is halted and the land is left to regenerate, the resulting growth of secondary forest may provide a viable habitat for folivorous and omnivorous lemur species. We aimed to identify the response of nocturnal lemurs to different successional stages of regenerating secondary, degraded mature, and mature forest across a mosaic-type landscape. We surveyed four nocturnal lemur species (Avahi laniger, Microcebus cf. simmonsi, Allocebus trichotis, and Daubentonia madagascariensis) in four forest types of varying habitat disturbance in northeastern Madagascar. We estimated densities in mature and regenerating secondary forest for the eastern woolly lemur (Avahi laniger) and mouse lemur (Microcebus cf. simmonsi), two sympatric species with folivorous and omnivorous diets respectively. We did not estimate densities of Allocebus trichotis and Daubentonia madagascariensis owing to small sample size; however, we observed both species exclusively in mature forest. We found higher population densities of A. laniger and M. cf. simmonsi in secondary than in mature forest, showing the potential of regenerating secondary forest for lemur conservation. Several environmental factors influenced the detectability of the two lemur species. While observer and habitat type influenced detection of the eastern woolly lemur, canopy height and vine density influenced detection of mouse lemurs. Understanding how different species with different diets interact with anthropogenically impacted habitat will aid future management decisions for the conservation of primate species.     

A New record of four <Emphasis Type="Italic">Penicillium</Emphasis> species isolated from <Emphasis Type="Italic">Agarum clathratum</Emphasis> in Korea

Agarum clathratum, brown algae, play important ecological roles in marine ecosystem, but can cause secondary environment pollution when they pile up on the beach. In order to resolve the environment problem by A. clathratum, we focus to isolate and identify Penicillium because many species are well known to produce extracellular enzymes. A total of 32 Penicillium strains were isolated from A. clathratum samples that collected from 13 sites along the mid-east coast of Korea in summer. They were identified based on morphological characters and phylogenetic analysis using β-tubulin DNA sequences as well as a combined dataset of β-tubulin and calmodulin. A total of 32 strains were isolated and they were identified to 13 Penicillium species. The commonly isolated species were Penicillium citrinum, P. roseomaculatum, and Penicillium sp. Among 13 Penicillium species, four species – P. bilaiae, P. cremeogriseum, P. madriti, and P. roseomaculatum – have not been previously recorded in Korea. For these four new species records to Korea, we provide morphological characteristics of each strain.     

Isolation of endophytic fungi from tropical forest in Indonesia

Endophytic fungi (EPF) are an important contributor to fungal diversity. It is surmised that EPF colonizing plant roots have high diversity. This study aimed to alleviate the scarcity of information regarding EPF in tropical forests, by isolationg and identifying EPF from a tropical forests in Indonesia. Soils were collected from five forests: (1) Tectona grandis monoculture; (2) Swietenia macrophylla monoculture; (3) Gmelina sp., Artocarpus champeden, Dipterocarp mixed; (4) Dipterocarp primary; (5) Macaranga sp. secondary. Four trees (Calliandra calothyrsus, Paraserianthes falcataria, Sesbania grandiflora, and Cassia siamea) and three crops (Sorghum bicolor, Allium fistulosum, and Trifolium repens) were grown in the forest soils to trap EPF. EPF were isolated from roots and isolation rates were calculated. Based on the isolation rates, P. falcataria and S. bicolor were chosen and grown again in forest soils. EPF were isolated and identified by their rDNA ITS1 region. Twelve and 21 EPF were isolated from 250 roots of P. falcataria and 300 roots of S. bicolor, respectively. Identified EPF were from genera Acrocalymma, Fusarium, Tolypocladium, Penicillium, Talaromyces, Exophiala, Dictyosporium, Pseudochaetosphaeronema, Mariannaea, Trichoderma, and Mycoleptodiscus. Acrocalymma, Tolypocladium, Penicillium, Exophiala, Pseudochaetosphaeronema, Mariannaea, and Mycoleptodiscus spp. were isolated from only one forest. Fusarium, Talaromyces, and Trichoderma spp. were isolated from more than one forest. The numbers of EPF isolated from Gmelina sp., Artocarpus champeden, Dipterocarp mixed forest, and Macaranga sp. secondary forest were higher than those from other forests, suggesting that different plant species in forests affect the root EPF community.     

Diversity and enzyme activity of <Emphasis Type="Italic">Penicillium</Emphasis> species associated with macroalgae in Jeju Island

A total of 28 strains of 19 Penicillium species were isolated in a survey of extracellular enzyme-producing fungi from macroalgae along the coast of Jeju Island of Korea. Penicillium species were identified based on morphological and β-tubulin sequence analyses. In addition, the halo-tolerance and enzyme activity of all strains were evaluated. The diversity of Penicillium strains isolated from brown algae was higher than the diversity of strains isolated from green and red algae. The commonly isolated species were Penicillium antarcticum, P. bialowiezense, P. brevicompactum, P. crustosum, P. oxalicum, P. rubens, P. sumatrense, and P. terrigenum. While many strains showed endoglucanase, β-glucosidase, and protease activity, no alginase activity was detected. There was a positive correlation between halo-tolerance and endoglucanase activity within Penicillium species. Among 19 Penicillium species, three species–P. kongii, P. olsonii, and P. viticola–have not been previously recorded in Korea.     

Taxonomic hierarchy of the phylum <Emphasis Type="Italic">Firmicutes</Emphasis> and novel <Emphasis Type="Italic">Firmicutes</Emphasis> species originated from various environments in Korea

This study assessed the taxonomic hierarchy of the phylum Firmicutes as well as elucidated the isolation and classification states of novel Firmicutes species isolated from Korean territory. The hierarchical classification system of the phylum Firmicutes has been developed since 1872 when the genus Bacillus was first reported and has been generally adopted since 2001. However, this taxonomic hierarchy is still being modified. Until Feb. 2017, the phylum Firmicutes consisted of seven classes (Bacilli, Clostridia, Erysipelotrichia, Limnochordia, Negativicutes, Thermolithobacteria, and Tissierellia), 13 orders, 45 families, and 421 genera. Firmicutes species isolated from various environments in Korea have been reported from 2000, and 187 species have been approved as of Feb. 2017. All Firmicutes species were affiliated with three classes (Bacilli, Clostridia, and Erysipelotrichia), four orders (Bacillales, Lactobacillales, Clostridiales, and Erysipelotrichales), 17 families, and 54 genera. A total of 173 species belong to the class Bacilli, of which 151 species were affiliated with the order Bacillales and the remaining 22 species with the order Lactobacillales. Twelve species belonging to the class Clostridia were affiliated within only one order, Clostridiales. The most abundant family was Bacillaceae (67 species), followed by the family Paenibacillaceae (56 species). Thirteen novel genera were created using isolates from the Korean environment. A number of Firmicutes species were isolated from natural environments in Korean territory. In addition, a considerable number of species were isolated from artificial resources such as fermented foods. Most Firmicutes species, belonging to the families Bacillaceae, Planococcaceae, and Staphylococcaceae, isolated from Korean fermented foods and solar salterns were halophilic or halotolerant. Firmicutes species were isolated from the whole territory of Korea, especially large numbers from Provinces Gyeonggi, Chungnam, and Daejeon.     

Significant patterns of fine-scale spatial genetic structure in a narrow endemic wind-dispersed tree species, <Emphasis Type="Italic">Cedrus brevifolia</Emphasis> Henry

Cedrus brevifolia is a narrowly distributed conifer species, currently limited to a single mountain in Cyprus, growing in restricted habitats on sites of different densities and sizes. This study assessed the influence of seed and pollen dispersal, as well as the effect of demographic and genetic features on the magnitude of fine-scale spatial genetic structure (SGS). Sampling was performed in 11 plots where 50 neighboring adult trees were sampled from each plot, while biparentally and paternally inherited genomes were used for analysis with microsatellites. Fine-scale SGS was significant but showed contrasting patterns among plots. Although the magnitude of SGS in C. brevifolia mainly results from restricted seed dispersal, short-distance pollen dispersal could also explain fine-scale SGS in some plots, which is rather uncommon in wind-pollinated conifer species. The lack of a general and consistent trend of SGS among plots and between genomes indicates that pollen and seed dispersal varies at plot level. The complex SGS patterns in C. brevifolia may result from the unequal ratio of male and female strobilies of trees within the same plots, at different reproductive periods. Demographic features such as habitat fragmentation did not influence the magnitude of SGS in C. brevifolia, whereas low tree aggregation reduced it. Further, the significant correlation observed between linkage disequilibrium (LD) and plots with significant SGS supports the assumption that under specific conditions, LD is likely to be caused by the magnitude of SGS.     

Monitoring thrips species with yellow sticky traps in astringent persimmon orchards in Korea

Thrips are one of the insect pests of persimmon (Diospyros kaki Thunb.) in the major production areas of astringent persimmon in Korea. We surveyed astringent persimmon orchards in the Damyang, Sangju and Cheongdo regions of Korea to determine thrips species composition and abundance. Orchards sprayed with either organic or conventional pesticides were sampled over the course of one flowering season, using yellow sticky traps to determine if this is a suitable method for monitoring thrips populations, and to determine thrips species composition and abundance. Eight thrips species were captured on yellow sticky traps in both the tree canopy and ground cover: Ponticulothrips diospyrosi Haga et Okajima, Scirtothrips dorsalis (Hood), Frankliniella occidentalis (Pergande), F. intonsa (Trybom), Thrips tabaci (Lindeman), T. hawaiiensis (Morgan), T. coloratus (Schmutz) and T. palmi (Karny). In all regions, F. occidentalis and F. intonsa dominated in both organic and conventional orchards. S. dorsalis, F. occidentalis, F. intonsa and T. hawaiiensis were found in persimmon flowers, with S. dorsalis the dominant thrips. Significantly more S. dorsalis were captured from flowers in the lower and middle canopy than in flowers from the upper canopy. Fruit damage was also significantly higher in fruit from the lower canopy than in fruit from the middle and upper canopy.     

<Emphasis Type="Italic">Viola woosanensis</Emphasis>, a recurrent spontaneous hybrid between <Emphasis Type="Italic">V. ulleungdoensis</Emphasis> and <Emphasis Type="Italic">V. chaerophylloides</Emphasis> (Violaceae) endemic to Ulleung Island,Korea

Ulleung Island is an oceanic volcanic island in Korea, which has never been connected to the adjacent continent. Previous studies highlighted Ulleung Island as an excellent system to study the pattern and process of early stages of flowering plant evolutions on oceanic island. The predominant mode of speciation in flowering plants on Ulleung Island appears to be anagenesis. However, the potentially important role of hybrid speciation among incompletely reproductively isolated lineages cannot be ruled out. Viola woosanensis (Violaceae) is of purportedly hybrid origin between V. ulleungdoensis (i.e., formerly recognized as V. selkirkii in Ulleung Island) and V. chaerophylloides, based on morphology. To examine the origin of V. woosanensis, we sampled a total of 80 accessions, including V. woosanensis and its putative parental species and sequenced nrDNA ITS, and four highly variable chloroplast noncoding regions (trnL-trnF, rpl16 intron, atpF-atpH, and psbA-trnH). Representative species of Viola from Korea were also included in the phylogenetic analyses (maximum parsimony, maximum likelihood, and Bayesian inference). Additive polymorphic sites in the nrDNA ITS regions were confirmed by cloning amplicons from representative species. The molecular data strongly supported the hybrid origin of V. woosanensis, and the maternal and paternal parent were determined to be V. ulleungdoensis and V. chaerophylloides, respectively. The presence of two parental ribotypes in V. woosanensis (with the exception in one population) was confirmed by cloning, suggesting V. woosanensis is primarily the F₁ generation. No trace of backcrossing and introgression with its parents was detected due to low fertility of hybrid species. We found a multiple and unidirectional hybrid origin of V. woosanensis. Additional studies are required to determine which factors contribute to asymmetric gene flow of Viola species in Ulleung Island.     

From grape berries to wine: population dynamics of cultivable yeasts associated to “Nero di Troia” autochthonous grape cultivar

The aim of this work was to study the biodiversity of yeasts isolated from the autochthonous grape variety called “Uva di Troia”, monitoring the natural diversity from the grape berries to wine during a vintage. Grapes were collected in vineyards from two different geographical areas and spontaneous alcoholic fermentations (AFs) were performed. Different restriction profiles of ITS–5.8S rDNA region, corresponding to Saccharomyces cerevisiae, Issatchenkia orientalis, Metschnikowia pulcherrima, Hanseniaspora uvarum, Candida zemplinina, Issatchenkia terricola, Kluyveromyces thermotolerans, Torulaspora delbrueckii, Metschnikowia chrysoperlae, Pichia fermentans, Hanseniaspora opuntiae and Hanseniaspora guilliermondii, were observed. The yeast occurrences varied significantly from both grape berries and grape juices, depending on the sampling location. Furthermore, samples collected at the end of AF revealed the great predominance of Saccharomyces cerevisiae, with a high intraspecific biodiversity. This is the first report on the population dynamics of ‘cultivable’ microbiota diversity of “Uva di Troia” cultivar from the grape to the corresponding wine (“Nero di Troia”), and more general for Southern Italian oenological productions, allowing us to provide the basis for an improved management of wine yeasts (with both non-Saccharomyces and Saccharomyces) for the production of typical wines with desired unique traits. A certain geographical-dependent variability has been reported, suggesting the need of local based formulation for autochthonous starter cultures, especially in the proportion of the different species/strains in the design of mixed microbial preparations.     

Mycorrhizal detection of native and non-native truffles in a historic arboretum and the discovery of a new North American species, <Emphasis Type="Italic">Tuber arnoldianum</Emphasis> sp. nov.

During a study comparing the ectomycorrhizal root communities in a native forest with those at the Arnold Arboretum in Massachusetts (USA), the European species Tuber borchii was detected on the roots of a native red oak in the arboretum over two successive years. Since T. borchii is an economically important edible truffle native to Europe, we conducted a search of other roots in the arboretum to determine the extent of colonization. We also wanted to determine whether other non-native Tuber species had been inadvertently introduced into this 140-year-old Arboretum because many trees were imported into the site with intact soil and roots prior to the 1921 USDA ban on these horticultural practices in the USA. While T. borchii was not found on other trees, seven other native and exotic Tuber species were detected. Among the North American Tuber species detected from ectomycorrhizae, we also collected ascomata of a previously unknown species described here as Tuber arnoldianum. This new species was found colonizing both native and non-native tree roots. Other ectomycorrhizal taxa that were detected included basidiomycetes in the genera Amanita, Russula, Tomentella, and ascomycetes belonging to Pachyphlodes, Helvella, Genea, and Trichophaea. We clarify the phylogenetic relationships of each of the Tuber species detected in this study, and we discuss their distribution on both native and non-native host trees.     

Relation to enterocins of variable <Emphasis Type="Italic">Aeromonas</Emphasis> species isolated from trouts of Slovakian aquatic sources and detected by MALDI-TOF mass spectrometry

Aeromonads represent bacteria thought to be primarily mostly autochthonous to aquatic environments. This study was focused on the relation with antibiotics and enterocins of identified Aeromonas species isolated from the intestine of trouts living in Slovakian aquatic sources. Intestinal samples from 50 trouts (3 Salmo trutta and 47 Salmo gairdnerii) were collected in April of years 2007, 2010, and 2015 from trouts of different water sources in Slovakia (pond Bukovec near Ko?ice, river ?ierny Váh). Due to the MALDI-TOF mass spectrometry evaluation, 25 strains were proposed to the genus Aeromonas involving nine different species (Aeromonas bestiarum—nine strains, Aer. salmonicida—four strains, Aer. encheleia, Aer. eucrenophila, Aer. molluscorum, Aer. media, Aer. sobria, Aer. popoffii, Aer. veronii). Phenotypic evaluation of individual strains confirmed their species identification. Twenty-five strains of different Aeromonas species were sensitive to azithromycin, amikacin, mecillinam, mezlocillin, piperacillin, gentamicin, chloramphenicol, and tetracycline. On the other side, they were resistant to carbenicillin and ticarcillin. The growth of Aer. bestiarum R41/1 was inhibited by treatment with Ent M and Ent 2019 (inhibition activity 100 AU/mL). Aer. bestiarum R47/3 was inhibited by eight enterocins (100 AU/mL). It is the first study testing enterocins to inhibit the growth of Aeromonas species from trouts.     

Spatial pattern and association of tree species in a mixed <Emphasis Type="Italic">Abies holophylla</Emphasis>-broadleaved deciduous forest in Odaesan National Park

The mixed Abies holophylla-broadleaved deciduous forest is mature relative to other forest types in the midland of South Korea. The spatial distribution patterns of eight dominant canopy tree species were analyzed using Ripley’s K function. This study was conducted to clarify interspecific and intraspecific associations among growth stages and to interpret the coexistence mechanism among such species, by extension, to forecast their future. Disturbance-driven site heterogeneity has spatially separated disturbance-resistant Magnolia sieboldii from the other seven species. Spatial distribution of other species is affected by dispersal mechanisms and interspecific and intraspecific competition. These species were classified into three groups. The first group, composed of A. holophylla, Tilia amurensis, Acer pseudo-sieboldianum, and Quercus mongolica, was the most dominant and intraspecifically affinitive. Additionally, it seemed that they were established before the others. Q. mongolica and T. amurensis are poorly resistant to shade and are likely to be crowded out. In contrast, the other two species may continue, as they are highly resistant to shade and have high reproductivity. The second group was composed of Carpinus cordata, Acer tegmentosum, and Acer mono, i.e., late-successional species that wait for chances with shade tolerance and high reproductivity. These species are expected to occupy much of the Q. mongolica and T. amurensis space. M. sieboldii, i.e., the third group, were negatively related with other species and have dominated the valleys where intense disturbances are repeated. Understories have poor reproductivity, but a stationary population is expected to be maintained if canopy gaps are created by occasional disturbances.     

Infectious Diseases in Free-Ranging Blonde Capuchins, <Emphasis Type="Italic">Sapajus flavius,</Emphasis> in Brazil

The main threats to primates worldwide are the degradation, fragmentation, and loss of their habitats; hunting (especially for bushmeat); and illegal trade. For many species, the most important threat is forest fragmentation, resulting in small populations that are restricted to isolated forest patches. In this situation, primates are particularly vulnerable to disease. The Endangered blonde capuchin (Sapajus flavius) is now restricted to a few forest patches in Northeast Brazil. We investigated the occurrence of parasites and bacterial diseases in one of three free-ranging groups of S. flavius in a small forest patch in Paraíba state, Northeast Brazil. We tested for antibodies against Leishmania spp., Trypanosoma cruzi, Toxoplasma gondii, Leptospira spp. (24 strains), and Brucella spp.. We used molecular analysis to detect Plasmodium spp., and evaluated blood smears for the presence of hemoparasites. All individuals tested negative for Leptospira spp. and B. abortus, but 8 of 48 (16%) presented antibodies for both Leishmania spp. and T. cruzi. We identified antibodies to T. gondii in 12% of the individuals tested. Plasmodium brasilianum infection was present in 4% of the individuals tested, and blood smears showed microfilariae parasites in 46% of the individuals tested. The occurrence of these infectious diseases in S. flavius may pose a significant threat in terms of reduced recruitment and poor survival rates, and an understanding of the influence of pathogens is crucial for the management of small populations of primates.     

South African mouse shrews (<Emphasis Type="Italic">Myosorex</Emphasis>) feel the heat: using species distribution models (SDMs) and IUCN Red List criteria to flag extinction risks due to climate change

Five species of mouse or forest shrews (Myosorex) are endemic to South Africa, Lesotho and Swaziland, four of which (Myosorex varius, Myosorex cafer, Myosorex longicaudatus and Myosorex cf. tenuis) are associated with montane or temperate grassland, fynbos and/or forest habitats while a fifth (Myosorex sclateri) is associated with lowland subtropical forests. Due to their small size, specialised habitat, low dispersal capacity, high metabolism and sensitivity to temperature extremes, we predicted that, particularly for montane species, future climate change should have a negative impact on area of occupancy (AOO) and ultimately extinction risks. Species distribution models (SDMs) indicated general declines in AOO of three species by 2050 under the A1b and A2 climate change scenarios (M. cafer, M. varius, M. longicaudatus) while two species (M. sclateri and M. cf. tenuis) remained unchanged (assuming no dispersal) or increased their AOO (assuming dispersal). While temperate species such as M. varius appear to be limited by temperature maxima (preferring cooler temperatures), the subtropical species M. sclateri appears to be limited by temperature minima (preferring warmer temperatures). Evidence for declines in AOO informed the uplisting (to a higher category of threat) of the Red List status of four Myosorex species to either vulnerable or endangered as part of a separate regional International Union for Conservation of Nature (IUCN) Red List assessment.     

Life history of <Emphasis Type="Italic">Gymnotus refugio</Emphasis> (Gymnotiformes; Gymnotidae): an endangered species of weakly electric fish

The present study describes the life history of Gymnotus refugio, a species classified as Endangered in the last published list of threatened species of the Brazilian fauna. The study was conducted at a conservation unity that protect one of the last remaining semideciduous forests in the region. The reproductive period was estimated as occurring from the end of winter to the last summer months. Gymnotus refugio exibited fractional spawning, the lowest relative fecundity registered among the Gymnotifomes species studied at the present, and male parental care behavior. The analyses showed a seasonal pattern on the species diet, associating different food categories to winter, autumn, and spring. According to food items analysis and estimated intestinal quotient, G. refugio was classified as invertivorous, feeding mainly on autochthonous insects. The results obtained herein suggest that the position of G. refugio as an Endangered species might be influenced by its territoriality, habitat specificity, parental care behavior, and low fecundity, reinforcing the importance of swampy forest environment conservation as the only means of the species maintenance.     

Schinzel–Giedion syndrome: a novel case,review and revised diagnostic criteria

Schinzel–Giedion syndrome (SGS) is a rare autosomal dominant inheritance disorder. Heterozygous de novo mutations in the SETBP1 gene have been identified as the genetic cause of SGS. Here, we report a novel case with the syndrome with a novel insertion mutation in SETBP1. We also present a review of SGS cases, and first revise diagnostic criteria of SGS based on clinical findings and/or SETBP1 mutation worldwide. A revised diagnostic criteria and typing of SGS can be determined. Type I (complex and classic type) SGS patients present a development delay and typical facial features (prominent forehead, midface retraction, and short and upturned nose) associated with hydronephrosis or two of the characteristic skeletal anomalies (a sclerotic skull base, wide occipital synchondrosis, increased cortical density or thickness, and broad ribs). Type II (middle type) patients show development delay and the distinctive facial phenotype (midface retraction, short and upturned nose), lacking both hydronephrosis and typical skeletal abnormalities, with existence of SETBP1 mutation. Type III (simple type) patients with SETBP1 alteration show their major symptom is development delay, in which expressive language delay is the most striking feature. Central nervous system involvement with development delay in which expressive language delay is much more obviously affected is the most prominent feature of SGS. There is another indication that severity of phenotype of SGS may be inversely correlated with degree of SETBP1 alteration, besides gain-of-function or dominant-negative effects in SETBP1 alteration causing SGS.     

Nucleotide polymorphisms of candidate genes of adaptive significance in the ural populations of <Emphasis Type="Italic">Larix sibirica</Emphasis> Ledeb.

The objectives of conservation and sustainable forest management require in depth study of genomes of woody plants and definition of their intraspecific genetic diversity. In recent years, an approach was developed based on the study of “candidate genes” that can potentially be involved in the formation of adaptive traits. In this study, we investigated nucleotide polymorphism of several adaptive candidate genes in the populations of Siberian larch (Larix sibirica Ledeb.) in the Urals. Representatives of this genus are among the most valuable and widely distributed forest tree species in Russia. From ten selected gene loci in the genome of L. sibirica, we isolated and investigated three loci, one of which (ABA-WDS) was sequenced in L. sibirica for the first time. The total length of the analyzed sequence in each individual amounted to 2865 bp. The length of locus alignment was from 360 bp to 1395 bp. In total, we identified 200 polymorphic positions. The most conservative is locus 4CL1-363, and the most polymorphic is locus sSPcDFD040B03103-274. The studied populations of L. sibirica are characterized by a high level of nucleotide polymorphism in comparison with other species and genuses (Picea, Pinus, Pseudotsuga, Abies) conifers plants (Hd = 0.896; π = 0.007; θ_W = 0.015). The most selectively neutral polymorphism (D _T =–0.997) was attributed to locus 4CL1-363, and polymorphism with high probability of adaptability (D _T =–1.807) was determined for the ABA-WDS locus. We identified 54 SNP markers, only five of which were nonsynonymous (9.26%) replacements. The average frequency of SNPs in the three studied loci of L. sibirica was one SNP in 53 bp. We detected unique SNP markers for eight populations, which could potentially be used to identify populations. Populations that are characterized by the highest number of unique SNP markers can be recommended for selection in order to preserve the gene pool of the species.
