First finds of <Emphasis Type="Italic">Prunus domestica</Emphasis> L. in Italy from the Phoenician and Punic periods (6th–2nd centuries <Emphasis Type="SmallCaps">bc</Emphasis>)

During the archaeological excavations in the Phoenician and Punic settlement of Santa Giusta (Oristano, Sardinia, Italy), dating back to the 6th–2nd centuries bc, several Prunus fruitstones (endocarps) inside amphorae were recovered. The exceptional state of preservation of the waterlogged remains allowed morphometric measurements to be done by image analysis and statistical comparisons made with modern cultivated and wild Prunus samples collected in Sardinia. Digital images of modern and archaeological Prunus fruitstones were acquired with a flatbed scanner and analysed by applying image analysis techniques to measure 26 morphometric features. By applying stepwise linear discriminant analysis, a morphometric comparison was made between the archaeological fruitstones of Prunus and the modern ones collected in Sardinia. These analyses allowed identification of 53 archaeological fruitstones as P. spinosa and 11 as P. domestica. Moreover, the archaeological samples of P. spinosa showed morphometric similarities in 92.5% of the cases with the modern P. spinosa samples currently growing near the Phoenician and Punic site. Likewise, the archaeological fruitstones identified as P. domestica showed similarities with the modern variety of P. domestica called Sanguigna di Bosa which is currently cultivated near the village of Bosa. Currently, these findings represent the first evidence of P. domestica in Italy during the Phoenician and Punic periods.     

Geometric morphometric analysis of <Emphasis Type="Italic">Setaria italica</Emphasis> (L.) P. Beauv. (foxtail millet) and <Emphasis Type="Italic">Brachiaria ramosa</Emphasis> (L.) Stapf. (browntop millet) and its implications for understanding the biogeography of small millets

Setaria italica (L.) P. Beauv. (foxtail millet) was originally domesticated in northern China. The time and route of its introduction into South Asia is currently unclear due to the possible confusion with autochthonous Brachiaria ramosa (L.) Stapf. (browntop millet). Geometric morphometrics (GM) offer an alternative to traditional archaeobotanical methods to distinguish between these two small millet species. This study aims at finding a method to securely distinguish among charred caryopses of S. italica and B. ramosa, testing its validity on archaeobotanical assemblages and proposing a new approach for studying the dispersion of S. italica throughout Eurasia. Modern S. italica (n = 35) and B. ramosa (n = 34) caryopses and 15 archaeological specimens from a 5th millennium bp archaeological occupation site in northwestern India were analysed. Archaeological and modern caryopses (before and after charring) were photographed with a Leica EZ4D stereoscope, and TPSdig software was used to scale the photographs and manually apply a configuration of three landmarks and six semi-landmarks onto the contours of the embryos. Multivariate statistics were carried out to analyse the shape differences between modern S. italica and B. ramosa and to classify the archaeological specimens. The results show that the shape of the embryo of both species can be clearly distinguished using a GM-approach, both before and after charring. However, charring tends to smooth the shape differences between the two groups, which may affect the interpretation of archaeobotanical assemblages. The comparison between modern and archaeological caryopses suggests that S. italica was not present in northwestern India during the 5th millennium bp.     

Prevalence of <Emphasis Type="Italic">VRN1</Emphasis> locus alleles among spring common wheat cultivars cultivated in Western Siberia

With the use of allele-specific primers developed for the VRN1 loci, the allelic diversity of the VRN-A1, VRN-B1, and VRN-D1 genes was studied in 148 spring common wheat cultivars cultivated under the conditions of western Siberia. It was demonstrated that modern Western Siberian cultivars have the VRN-A1a allele, which is widely distributed in the world (alone or in combination with the VRN-B1a and VRN-B1c alleles). It was established that the main contribution in acceleration of the seedling–heading time is determined by a dominant VRN-A1a allele, while the VRNA1b allele, on the contrary, determines later plant heading. Cultivars that have the VRN-A1b allele in the genotype are found with a frequency of 8%. It was shown that cultivars with different allele combinations of two dominant genes (VRN-A1a + VRN-B1c and VRN-A1a + VRN-B1a) are characterized by earlier heading and maturing.     

Development of co-dominant KASP markers co-segregating with Ug99 effective stem rust resistance gene <Emphasis Type="Italic">Sr26</Emphasis> in wheat

Stem rust of wheat, caused by Puccinia graminis f. sp. tritici (Pgt), is a threat to global food security due to its ability to cause total crop failures. The Pgt race TTKSK (Ug99) and its derivatives detected in East Africa carry virulence for many resistance genes present in modern cultivars. However, stem rust resistance gene Sr26 remains effective to all races of Pgt worldwide. Sr26 is carried on the Agropyron elongatum (syn. Thinopyrum ponticum) segment 6Ae#1L translocated to chromosome 6AL of wheat. In this study, a recombinant inbred line (RIL) population derived from a cross between the landrace Aus27969 and Avocet S, which carries Sr26, was used to develop co-dominant kompetitive allele-specific polymerase chain reaction (KASP) markers that co-segregate with Sr26. Four KASP markers (sunKASP_216, sunKASP_218, sunKASP_224 and sunKASP_225) were also shown to co-segregate with Sr26 in four additional RIL populations. When tested on Australian cultivars and breeding lines, these markers amplified alleles alternate to that linked with Sr26 in all cultivars known to lack this gene and Sr26-linked alleles in cultivars and genotypes known to carry Sr26. Genotypes WA-1 and WA-1/3*Yitpi carrying the shortest Sr26 translocation segment were positive only for markers sunKASP_224 and sunKASP_225. Our results suggest the four KASP markers are located on the original translocation and sunKASP_224 and sunKASP_225 are located on the shortened version. Therefore, sunKASP_224 and sunKASP_225 can be used for marker-assisted pyramiding of Sr26 with other stem rust resistance genes to achieve durable resistance in wheat.     

New species of Telenominae (Hymenoptera,Scelionidae) from the palaearctic fauna

Four new species of Telenominae of the genera Telenomus and Platytelenomus, collected in the territory of the Ukraine, Hungary, and Japan, were described: Telenomus (T.) bicolorus Kononova, T. (T.) ardens Kononova, (T.) michaylovi Kononova, and Platytelenomus mirabilis Kononova. Brief morphological characteristics of the genera Telenomus and Platytelenomus are given, and some notes concerning biology and geographical distribution of the species are presented. Telenomus (T.) bicolorus differs from all the known species of the genus Telenomus in the two-colored body: head and thorax yellow with brownish tint ventrally, mesothorax and abdomen black. The main distinguishing feature of T. (T.) ardens is its smooth shining body, T. (T.) michaylovi is similar to T. (T.) rudis Kozlov. These species can be distinguished by the structure of their antenna. The second to fourth segments of the antennal clava are transverse in T. (T.) michaylovi and are as long as wide in T. (T.) rudis. In addition, the abdominal stem and abdominal tergite II are smooth and shining, while the abdominal stem in T. (T.) rudis is striate along the entire length, and tergite II is finely striate along half of its length. Platytelenomus mirabilis is closely related to P. danubialis Szelényi, but differs in the strongly flattened body, sculpture of the abdominal stem and tergite II, and coloration of the legs. The thorax of P. mirabilis is 4–5 times as wide as high, the abdominal stem is striate along the entire length, tergite II is striate at the base, and the legs, including coxae, are yellow. The thorax of P. danubialis is 4 times as wide as high, the abdominal stem and tergite II are smooth and shining, and the legs are brown.     

Foraminifera and their associations of a possibly Rhaetian section of the Nayband Formation in central Iran,northeast of Esfahan

The following paper describes the foraminiferal fauna and associated faunal assemblages of the bedded and reef carbonates of the Upper Triassic (most probably Rhaetian) Nayband Formation, which are exposed in a section south of the small town of Bagher-Abad, northeast of Esfahan. Foraminifers are extremely rare in sponge- or coral-dominated bioconstructions and in the bedded carbonates of the Nayband Formation in central Iran. Some carbonate beds are composed of bioclastic wackstone/packstone. These are exposed in the solenoporacean horizon at the uppermost part of the section. Here, the aulotortid- and trocholinid-type foraminifers are relatively abundant. The following foraminiferal taxa with different abundances were found within the carbonates of the investigated section: Trocholina umbo Frentzen, T. turris Frentzen, T. gracilis Blau, Aulotortus tumidus (Kristan-Tollmann), Aulotortus tenuis (Kristan), Aulotortus friedli (Kristan-Tollmann), Coronipora etrusca (Pirini), Semiinvoluta clari Kristan, Turrispirillina? licia variabilis Blau, Galeanella? laticarinata Al-Shaibani, Carter and Zaninetti, Ophthalmidium sp., Agathammina sp., “Sigmoilina” schaeferae Zaninetti, Planiinvoluta carinata Leischner, Planiinvoluta sp., Nubecularia sp., Endothyra sp., Paeolituonella sp. and some sessile agglutinated and nodosariid types. All mentioned taxa are very rare, except the involutinid and trocholinid types. The following species are described as new: Trocholina blaui nov. sp., Spirilina? iranica nov. sp., and Coronipora serraforma nov. sp. Trocholina blaui is usually attached to solenoporacean thalli. Four foraminiferal associations, which are named after the occurrence of the abundant species, were distinguished as Aulotortus tumidus association, Aulotortus friedli association, Trocholina umbo association, and Trocholina blaui association. Aulotortid types and Trocholina umbo were found within the bioclastic wackstone/packstone carbonates. Trocholina blaui is abundant in solenoporacean framestones. The foraminiferal association of investigated carbonates contains a mixed fauna, known from Upper Triassic–Liassic in the Tethyan realm. Carbonates of the whole investigated section are dated—due to occurrence of the genus Aulotortus, with species A. tumidus (Kristan-Tollmann), A. tenuis (Kristan), and A. friedli (Kristan-Tollmann)—as Upper Triassic (most probably Rhaetian). The “typical” foraminifers occurring in the reef biotopes in the northwestern Tethys are either missing or extremely rare in the Iranian bioconstructions.     

Antigenic polysaccharides of bacteria: 41. Structures of the O-specific polysaccharides of <Emphasis Type="Italic">Shigella dysenteriae</Emphasis> types 4 and 5 revised by NMR spectroscopy

The earlier established structures of the acidic O-specific polysaccharides from two typical strains of the Shigella dysenteriae bacterium were revised using modern NMR spectroscopy techniques. In particular, the configurations of the glycosidic linkages of GlcNAc (S. dysenteriae type 4) and mannose (S. dysenteriae type 5) residues were corrected. In addition, the location of the sites of non-stoichiometric O-acetylation in S. dysenteriae type 4 was determined: the lateral fucose residue was shown to be occasionally O-acetylated; also, theposition of the O-acetyl group present at the stoichiometric quantity in S. dysenteriae type 5 was corrected. The revised structures of the polysaccharides studied are shown below. The known identity of the O-specific polysaccharide structures of S. dysenteriae type 5 and Escherichia coli O58 was confirmed by ¹³C NMR spectroscopy and, hence, the structure of the E. coli O58 polysaccharide should be revised in the same manner.

A revision of the Jurassic Stonefly Genera <Emphasis Type="Italic">Dobbertiniopteryx</Emphasis> Ansorge and <Emphasis Type="Italic">Karanemoura</Emphasis> Sinitshenkova (Insecta: Plecoptera), with the description of new species from the Daohugou locality,China

The stonefly genera Dobbertiniopteryx Ansorge and Karanemoura Sinitshenkova are revised. Based on new material from the Middle Jurassic of Daohugou, China, two new species, D. juracapnia sp. nov. and K. manca sp. nov., are described and Karanemoura abrupta Sinitshenkova, 1987 is redescribed. K. desiliens Sinitshenkova, 1987 is excluded from Karanemoura; its position within the family Perlariopseidae remains uncertain. The placement of Dobbertiniopteryx in the modern family Capniidae is confirmed. The perfect state of preservation of the nearly complete adult stonefly remains from China made it possible to improve and extend the diagnoses of the Perlariopseidae and Dobbertiniopteryx. The geological background of the Daohugou deposits is briefly discussed.     

New Zealand Eocene,Oligocene and Miocene Macrofossil and Pollen Records and Modern Plant Distributions in the Southern Hemisphere

The modern New Zealand flora has a relatively low number of families and genera in relation to land area, but well-preserved macrofossils and pollen from three sites in southern New Zealand suggest that the floras in Eocene, Oligocene and Miocene times were much more diverse at the generic level. At Pikopiko, Southland, a late Eocene in situ forest with fern understory was dominated by conifers, Casuarinaceae, Lauraceae, Nothofagus, Proteaceae, and mesothermal angiosperms including palms (aff. Calamus), Sapindaceae: Cupaniae and Picrodendraceae. At Newvale Mine, Southland, a leaf bed within a thick lignite seam represents leaf fossils preserved in a late Oligocene oligotrophic bog. This site demonstrates that Agathis, Dacrycarpus, Dacrydium, Halocarpus, Microcachrys, Podocarpus and Phyllocladus coexisted with diverse angiosperms including Nothofagus, Gymnostoma, Cunoniaceae, Ericaceae, Sapindaceae and several Proteaceae. Pollen data add Meliaceae, Myrtaceae, Onagraceae and Rubiaceae to the flora. At Foulden Maar, Otago, mummified leaves and flowers, including several with in situ pollen, demonstrate the existence of a diverse flora surrounding an Early Miocene lake. This site contains numerous monocot macrofossils including Astelia, Cordyline, Ripogonum and Typha, as well as the oldest fossils known for Orchidaceae and Luzuriagaceae. This flora was dominated by Lauraceae with affinities to Cryptocarya and Litsea, but other families include Araliaceae, Cunoniaceae, Elaeocarpaceae, Euphorbiaceae sensu lato, Menispermaceae, Myrsinaceae, Myrtaceae, Onagraceae, Proteaceae and Sterculiaceae. Many ferns, conifers, and Nothofagus are from lineages with Gondwanan ancestors, whereas other taxa show links to Australia (e.g., Gyrostemonaceae), New Caledonia (e.g., Beauprea) and South America (e.g., Luzuriaga, Fuchsia). Many of these taxa are now extinct in New Zealand, and therefore indicate much wider biogeographic ranges for many families and genera in the past.     

New and little known species of the dance-fly subgenus <Emphasis Type="Italic">Xanthempis</Emphasis> Bezzi,genus <Emphasis Type="Italic">Empis</Emphasis> L. (Diptera,Empididae), from the Caucasus

Five new species of the subgenus Xanthempis Bezzi are described from the Caucasus: Empis (Xanthempis) annae sp. n. (Russia: Krasnodar Territory), E. (X.) grichanovi sp. n. (Russia: Krasnodar Territory; Georgia), E. (X.) pseudoconcolor sp. n. (Russia: Krasnodar and Stavropol territories; Georgia: Abkhazia), E. (X.) teberdaensis sp. n. (Russia: Karachay-Cherkessia), and E. (X.) zamotajlovi sp. n. (Russia: Krasnodar Territory and Adygea). The females of E. (X.) alanica Shamshev and E. (X.) kovalevi Shamshev are described for the first time. New data on the distribution of some previously described species are reported. The geographical distribution of Xanthempis is discussed. A key to Xanthempis species from the Caucasus is compiled.     

Revision of the shield-bug genera <Emphasis Type="Italic">Holcostethus</Emphasis> Fieber and <Emphasis Type="Italic">Peribalus</Emphasis> Mulsant et Rey (Heteroptera,Pentatomidae) of the Palaearctic Region

A complex of the heteropteran genera centering around Peribalus Mulsant et Rey and Holcostethus Fieber is considered. The genus Dryadocoris Kirkaldy reveals no relationship with the above genera and is believed to represent a separate clade of the family Pentatomidae. The genera Peribalus and Holcostethus are revised. The former includes three subgenera: Peribalus s. str. with two species, Asioperibalus subgen. n. (type species Cimex inclusus Dohrn) with six species, and Tianocoris subgen. n. (type species Holcostethus manifestus Kiritshenko) with two species. Holcostethus embraces two subgenera: Holcostethus s. str. and the monotypic Enigmocoris subgen. n. (type species H. fissiceps Horváth). Two new species are described: Peribalus tianshanicus sp. n. from the Tien Shan Mts. and P. przewalskii sp. n. from the northern part of China (Huan He River). P. capitatus Jakovlev and P. vernalis (Wolff) are downgraded to subspecies of P. strictus (F.). P. ovatus Jakovlev is synonymized with P. inclusus (Dohrn). Two new monotypic genera related to the revised complex of genera are established, Paraholcostethus gen. n. (type species Peribalus breviceps Horváth) and Himalayastethus gen. n. (type species H. pilosus sp. n. from Kashmir). A key to, and morphometric characters for all the taxa considered are provided. The key characters, including both male and female genitalia, are illustrated, and distributional maps are given.     

New species of the buprestid genus <Emphasis Type="Italic">Endelus</Emphasis> Deyrolle (Coleoptera,Buprestidae) from China,India, and Laos

Endelus (Kubaniellus) indicus sp. n. from India, E. (K.) lao sp. n. and E. (K.) khnzoriani sp. n. from Laos, E. (s. str.) sausai sp. n. from China, and E. (s. str.) dembickyi sp. n. from India are described, the two latter species are included in the Endelus bicarinatus Théry, 1932 species-group recently established by the author. E. collinus Obenberger, 1922 is included in this group; lectotype of this species is designated. Keys to species of the subgenus Kubaniellus and of the E. collinus group are provided. E. (K.) kareni Kalashian is for the first time recorded for Shaanxi Prov., E. pacholatkoi Kalashian, E. smaragdinus Desc. et Vill., and E collinus Obenb., for Laos (the latter species, also for Myanmar).     

Screening of rice landraces (<Emphasis Type="Italic">Oryza sativa</Emphasis> L.) for seedling stage salinity tolerance using morpho-physiological and molecular markers

Traditional rice landraces of coastal area in Bangladesh are distinct regarding their phenotype, response to salt stress and yield attributes. With characterization of these landraces, suitable candidate genes for salinity tolerance could be identified to introgress into modern rice varieties. Therefore, the aim of this experiment was to uncover prospective rice landraces tolerant to salinity. Relying on morphological, biochemical and molecular parameters 25 rice genotypes were tested for salt tolerance at germination and seedling stage. At germination stage 0 and 12 dSm^?1 salinity were imposed on rice genotypes. Ward’s cluster analysis divided rice genotypes into three clusters (susceptible, moderately tolerant and tolerant) based on the physiological indices. The tolerant rice landraces to salinity were Sona Toly, Nakraji and Komol Bhog. At seedling stage screening was performed following IRRI standard protocol at 12 dSm^?1 salinity level. Based on all morphological and biochemical parameters Komol Bhog was identified as the highly salinity tolerant landrace while Bolonga, Sona Toly, Dud Sail, Tal Mugur and Nakraji were found as tolerant to salinity. Molecular characterization using two simple sequence repeats (SSR) markers, viz. RM121 and RM337 displayed Bolonga, Til Kapor, Panbra, Sona Toly, Bina Sail, Komol Bhog, Nakraji, Tilkapur, Gajor Goria and Gota were tolerant landraces through genetic similarity in dendrogram. These identified salt-resistant landraces can be used as promising germplasm resources for breeding salt-tolerant high-yielding rice varieties in future.     

Novel sources of resistance to Septoria nodorum blotch in the Vavilov wheat collection identified by genome-wide association studies

Key message

The fungus Parastagonospora nodorum causes Septoria nodorum blotch (SNB) of wheat. A genetically diverse wheat panel was used to dissect the complexity of SNB and identify novel sources of resistance.

Abstract

The fungus Parastagonospora nodorum is the causal agent of Septoria nodorum blotch (SNB) of wheat. The pathosystem is mediated by multiple fungal necrotrophic effector–host sensitivity gene interactions that include SnToxA–Tsn1, SnTox1–Snn1, and SnTox3–Snn3. A P. nodorum strain lacking SnToxA, SnTox1, and SnTox3 (toxa13) retained wild-type-like ability to infect some modern wheat cultivars, suggesting evidence of other effector-mediated susceptibility gene interactions or the lack of host resistance genes. To identify genomic regions harbouring such loci, we examined a panel of 295 historic wheat accessions from the N. I. Vavilov Institute of Plant Genetic Resources in Russia, which is comprised of genetically diverse landraces and breeding lines registered from 1920 to 1990. The wheat panel was subjected to effector bioassays, infection with P. nodorum wild type (SN15) and toxa13. In general, SN15 was more virulent than toxa13. Insensitivity to all three effectors contributed significantly to resistance against SN15, but not toxa13. Genome-wide association studies using phenotypes from SN15 infection detected quantitative trait loci (QTL) on chromosomes 1BS (Snn1), 2DS, 5AS, 5BS (Snn3), 3AL, 4AL, 4BS, and 7AS. For toxa13 infection, a QTL was detected on 5AS (similar to SN15), plus two additional QTL on 2DL and 7DL. Analysis of resistance phenotypes indicated that plant breeders may have inadvertently selected for effector insensitivity from 1940 onwards. We identify accessions that can be used to develop bi-parental mapping populations to characterise resistance-associated alleles for subsequent introgression into modern bread wheat to minimise the impact of SNB.

     

Genome: Origins and evolution of the term

The appearance of a new scientific term is a significant event in the human cognitive process and the result of the realization of the separateness of an object or a phenomenon. Our article concentrates on the origins of basic genetic terms, such as genetics, gene, genotype, genome, gene pool, and genomics. We propose using the term karyogenomics for the special direction of genomics related to the study of the organization and evolution of eukaryotic genomes by means of modern chromosome analysis, as well as by full genome sequencing.     

Little known leaf beetles of the genus <Emphasis Type="Italic">Chrysolina</Emphasis> (Coleoptera,Chrysomelidae) from China

Chrysolina (Semenowia) chalcea (Weise, 1889), Ch. (Pezocrosita) cyanopurpurea (Ballion, 1878), and Ch. (Chrysocrosita) fuyunica Chen, 1961 are redescribed. A male (topotype) of Ch. cyanopurpurea was examined for the first time. Ch. belousovi Lopatin, 2000 is a new junior synonym of Ch. cyanopurpurea; Ch. bienkowskii Lopatin, 2000 is a new junior synonym of Ch. chalcea. The taxonomic position of all the taxa mentioned is discussed.     

Structural Polymorphism of <Emphasis Type="Italic">Sinorhizobium meliloti</Emphasis> Genes Related to Virulence and Salt Tolerance

Analysis of the structural polymorphism of eight genes in Sinorhizobium meliloti (nodA, nodB, nodC, and nodH, as well as betA, betB, betC, and betB2) involved in virulence control and salt tolerance, respectively, was carried out in native populations from two geographically distant areas of alfalfa diversity. These areas are located in the North Caucasian gene center of cultivated plants (NCG) and in the modern center of introgressive hybridization of alfalfa located next to the Aral Sea area (PAG) subjected to salinization. RFLP types (alleles) of the nod and bet genes, similar to those in the reference strain Rm1021 (A-type) and different from them (divergent, or D-type alleles) were revealed. The combinations for A- and D-type alleles of the aforementioned genes (analysis of the linkage disequilibrium, LD) were studied in both populations. It was shown that D-type alleles of the nod genes were two times more frequent in the NCG population, while D-type alleles of the bet genes were predominantly identified in the PAG population. At the same time, different combinations of D-type alleles of both the nod and bet genes prevailed in populations. For instance, in the case of the glycine betaine metabolism pathway, these were the betC and betB2 genes in NCG population and betB and betA genes in PAG population. The state of linkage disequilibrium was shown for 60.7% of combinations of alleles of the nod and bet genes in the S. meliloti strains from NCG and more than twice less in strains from the PAG population. It was concluded that clonal lines prevailed in NCG, while the PAG population of S. meliloti had a panmictic structure with revealed single clonal lines.
