Linkage assignment of eleven genes to the porcine genome

We report comparative linkage mapping of eleven genes in the swine genome by RFLP analysis. These genes include: Acid phosphatase type 5 (ACP5), Cholecystokinin Type B Receptor (CCKBR), Antibiotic Peptide (FALL39), Insulin-like Growth Factor 1 Receptor (IGF1R), Integrin Alpha M (ITGAM), Integrin Beta 2 (ITGβ2), Opioid Receptor Mu-1 (OPRM1), Pro-hormone Converter (PC1/3), Retinol Binding Protein 3 (RBP3), Ribosomal DNA (RNR1), and Zona Pellucida Glycoprotein 1 (ZP1). The CCKBR and ITGβ2 loci define the ends of the linkage groups on Chromosomes (Chro) (SSC) 9p and 13qter, respectively. Received: 15 December 1996 / Accepted: 31 March 1997     

Cape Delil-de-la-Kroiera (Sakhalin Island)—A new nesting point of marine birds

Two kekurs on Cape Delil-de-la-Kroiera (east coast of Sakhalin Island, to the north of Cape Ratmanova) were surveyed on July 16, 2003. Nesting of six species of sea birds was observed: slaty-backed gull (Larus schistisagus), black-legged kittiwake (Rissa tridactyla), common murre (Uria aalge), spectacled guillemot (Cepphus carbo), horned puffin (Fratercula corniculata), and tufted puffin (Lunda cirrhata).Original Russian Text Copyright © 2005 by Biologiya Morya, Blokhin, Tiunov.     

Genomic mapping of chemokine and transforming growth factor genes in swine

Five chemokine genes, transforming growth factors alpha, beta 2 and 3 (TGFBA, TGFB-2, and TGFB-3), interleukin 8 (IL-8), and monocyte chemoattractant protein 2 (MCP-2), were mapped to porcine linkage groups on Chromosomes 3q, 10p, 7q, 8, and 12q, respectively. Restriction fragment length polymorphisms (RFLPs) for these genes were developed by Southern blot hybridization after digestion of porcine genomic DNA with BamHI and MspI (TGFBA), BamHI and PvuII (TGFB-2), HindIII (TGFB-3), BglII (IL-8), and PstI (MCP-2) and used to genotype the USDA-MARC Swine Reference Population pigs. Sufficient informative meioses, 61 (TGFBA), 58 (TGFB-2), 28 (TGFB-3), 38 (IL-8), and 156 (MCP-2), were available to pursue two-point pairwise linkage analysis with over 1,000 existing loci in the USDA-MARC genome database to establish initial linkage (LOD > 3). Multi-point analysis with CRIMAP determined the most likely order for each new marker. The assignment of the five chemokine genes in swine concurs with previous porcine/human chromosomal homologies based on results from ZOO-FISH and chromosomal painting experiments. These findings add five new informative Type I markers within a single gene family to the swine genome and may help us understand the genetic basis for disease resistance in livestock.

Linkage mapping of mutant loci in rye (Secale cereale L.)

Eight mutant loci determining the traits waxy plant (w and wa1), brown culm (cb), multiple pistils (mp), weak plant with reduced plant height (np), monoculm growth habit (mc), compactum growth habit (ct3) and anthocyaninless (an) were mapped on rye chromosomes 4R (w, np), 6R (cb, mc) and 7R (mp, wa1, ct3, an). For five mutants (w, wa1, cb, mp, np) molecular and biochemical markers were applied, whereas for mc, ct3 and an a classical linkage analysis was performed. Furthermore, it could be demonstrated that homoeologous relationships exist between most of the mapped rye loci and comparable mutants in wheat and barley. It was confirmed not only that genes controlling fundamental aspects of plant biology are highly conserved across the Triticeae species but so also were many mutant loci.

Chromosomes of five artiodactyl mammals

Somatic chromosomes of six specimens belonging to the following five species of artiodactyls (Artiodactyla: Mammalia) are described: A female nilgai (Boselaphus tragocamelus), 2n=46; male baresingha (Rucervus duvauceli), two specimens, 2n=56; a female Himalayan tahr (Hemitragus jemlahicus), 2n=48; a female Kirk's dik-dik (Rhynchotragus kirki), 2n=46; and a male sambar (Cervus unicolor), 2n=58. In the baresingha and the sambar, one or more acrocentric chromosomes carried satellites on their long arms. ³H-thymidine radioautographs of cultured cells of the Himalayan tahr showed a long acrocentric chromosome to be late-replicating, suggesting that it is an X chromosome.     

Chromosomal location of genes participating in the degradation of purines in Pseudomonas aeruginosa.

Summary Genetic mapping of the genes (puu) that encode the enzymes catalysing degradation of purines in Pseudomonas aeruginosa strain PAO has been carried out. Mutants that are deficient in adenine deaminase (puuA), guanine deaminase (puuB), xanthine dehydrogenase (puuC), uricase (puuD), allantoinase (puuE), and/or allantoicase (puuF) were isolated and used for the genetic study. Conjugation by FP5 factor and generalized transduction by phage G101 gave the following map locations of these six genes on the chromosome: hisI-puuB-hisII; trpA,B-puuA-ilv202; met9011-catA1-tyu-nar9011-(puuC, puuD, puuE)-puuF. A close linkage among the puuC, puuD and puuE was demonstrated by the transduction.     

Response of bioluminescent bacteria to sixteen azo dyes

Recombinant bioluminescent bacteria were used to monitor and classify the toxicity of azo dyes. Two constitutive bioluminescent bacteria,Photobacterium phosphoreum andEscherichia coli, E. coli GC2 (lac::luxCDABE), were used to detect the cellular toxicity of the azo dyes. In addition, four stress-inducible bioluminescentE. coli, DPD2794 (recA::luxCDABE), a DNA damage sensitive strain; DPD2540 (fabA::luxCDABE), a membrane damage sensitive strain; DPD2511 (katG::luxCDABE), an oxidative damage sensitive strain; and TV1061 (grpE::luxCDABE), a protein damage sensitive strain, were used to provide information about the type of toxicity caused by crystal violet, the most toxic dye of the 16 azo dyes tested. These results suggest that azo dyes result in serious cellular toxicity in bacteria, and that toxicity monitoring and classification of some azo dyes, in the field, may be possible using these recombinant bioluminescent bacteria.     

Evaluation of commercial essential oil samples on the growth of postharvest pathogen Monilinia fructicola (G. Winter) Honey

Aim: To assess the effect of several commercial essential oils samples Australian lemon myrtle (Backhousia citriodora), cinnamon bark (Cinnamomum zeylanicum), oregano (Origanum vulgare), thyme oil (Thymus vulgaris), clove bud (Eugenia caryophyllata), valerian (Valeriana officinalis) and Australian tea tree oil (Melaleuca alternifolia) on mycelium growth and spore germination of Monilinia fructicola. The effectiveness of lemon myrtle essential oil as a fumigant for the control of brown rot in nectarines was evaluated. Methods and Results: Monilinia fructicola exhibited a different level of sensitivity to each tested essential oil with results suggesting that the essential oils provide excellent control of the pathogen with respect to mycelium growth and spore germination at very low concentrations, whereas for others higher concentrations are needed to reduce significant fungal growth. In vivo application of lemon myrtle essential oil effectively reduced the incidence of M. fructicola on noninoculated fruit. Fumigation of nectarines following inoculation did not reduce the incidence of brown rot in comparison with the inoculated control treatment. No evidence of phytotoxicity on the fruit was recorded. Conclusions: Lemon myrtle essential oil exhibited the strongest antifungal activity against M. fructicola, in vitro and to a lesser extent, under in vivo conditions. Significance and Impact of the Study: The results demonstrate that lemon myrtle essential oil, in particular, has potential as an antifungal agent to control M. fructicola.     

Evolution of an intronic microsatellite polymorphism in Toll-like receptor 2 among primates

Nonhuman primates express varying responses to Mycobacterium tuberculosis: New World monkeys appear to be resistant to tuberculosis (TB) while Old World monkeys seem to be particularly susceptible. The aim of this study was to elucidate the presence of the regulatory guanine–thymine (GT) repeat polymorphisms in intron 2 of Toll-like receptor 2 (TLR2) associated with the development of TB in humans and to determine any variations in these microsatellite polymorphisms in primates. We sequenced the region encompassing the regulatory GT repeat microsatellites in intron 2 of TLR2 in 12 different nonhuman primates using polymerase chain reaction amplification, TA cloning, and automatic sequencing. The nonhuman primates included for this study were as follows: chimpanzee (Pan troglodytes), bonobo (Pan paniscus), gorilla (Gorilla gorilla), orangutan (Pongo pygmaeus), Celebes ape (Macaca nigra), rhesus monkey (Macaca mulatta), pigtail macaque (Macaca nemestrina), patas monkey (Erythrocebus patas), spider monkey (Ateles geoffroyi), Woolly monkey (Lagothrix lagotricha), tamarin (Saguinus labiatus), and ring-tailed lemur (Lemur catta). Nucleotide sequences encompassing the regulatory GT repeat region are similar across species and are completely conserved in great apes. However, Old World monkeys lack GT repeats altogether, while New World monkeys and ring-tailed lemurs have much more complex structures around the position of the repeats. In conclusion, the genetic structures encompassing the regulatory GT repeats in intron 2 of human TLR2 are similar among nonhuman primates. The sequence is most conserved in New World monkeys and less in Old World monkeys.     

New lanostane-type triterpenoids, inonotsutriols D, and E, from Inonotus obliquus

Two new lanostane-type triterpenoids, inonotsutriols D (1) and E (2), were isolated from the sclerotia of Inonotus obliquus (Pers.: Fr.) Pil. (Japanese name: kabanoanatake; Russian name: chaga). Their structures were determined to be lanost-8-ene-3β,22R,24R-triol (1) and lanost-8-ene-3β,22R,24S-triol (2) on the basis of spectral data, including 2D NMR analysis. In addition, major compounds, inotodiol (3), trametenolic acid (4), 3β-hydroxylanosta-8,24-dien-21-al (5), 21-hydroxylanosterol (6), inonotsuoxide A (7) and inonotsuoxide B (8) were identified, and all compounds, except 2, were evaluated for their cancer cell growth inhibitory activity against P388, HL-60, L1210 and KB cell lines.     

New species of the subfamily Cossoninae (Coleoptera: Curculionidae) in Dominican amber

The following new genus and seven new species of Cossonine weevils (Curculionidae: Cossoninae) are described from Dominican amber: Acamptus exilipes Poinar and Legalov, n. sp. (similar to A. rigidus), Caulophilus camptus Poinar and Legalov, n. sp. (similar to C. bennetti), Caulophilus elongatus Poinar and Legalov, n. sp. (similar to C. swensoni), Caulophilus ruidipunctus Poinar and Legalov, n. sp., Dryotribus pedanus Poinar and Legalov, n. sp. (similar to D. amplioculus), Ogygius obrieni Poinar and Legalov, n. gen., n. sp. (similar to the genus Apotrepus), and Stenotrupis pumilis Poinar and Legalov, n. sp. (similar to S. breviscapus). A key to the Dominican amber species of the genus Caulophilus is provided. Based on the extant weevil fauna, it appears that the Hispaniolan Cossonine were more diverse in the Tertiary than at present. http://zoobank.org/urn:lsid:zoobank.org:pub:14D1CFC0-4967-4D22-888B-0DE3E157D6BD     

Relationship of otolith length to fish total length in six demersal species from the NW Mediterranean Sea

Relationships between otolith major axis length (mm) and fish size (total length, cm) were described by means of linear regression analysis for six demersal fish species from the NW Mediterranean: blue whiting (Micromesistius poutassou), greater forkbeard (Phycis blennoides), red mullet (Mullus barbatus), poor cod (Trisopetus minutus capelanus), horse mackerel (Trachurus trachurus), and Mediterranean mackerel (Trachurus mediterraneus). Results show that reconstruction of body size from otolith measurement is possible by applying this approach based on the relationship of otolith length – fish length.     

Deposition of type and voucher material from the helminthological collection of Elon E. Byrd

Elon E. Byrd was a prominent helminth taxonomist who published between 1930–1965. After his death in 1974, his collection was put in storage at the University of Georgia School of Veterinary Medicine. A recent examination of his collection yielded a number of taxonomically valuable specimens that should be available to research workers worldwide. This paper enumerates the specimens recovered and their deposition. Digenean families and genera represented are: Brachycoeliidae (Brachycoelium), Dicrocoeliidae (Paradistomum), Lecithodendriidae (Prosthodendrium, Pseudosonsinotrema), Microphallidae (Levinseniella), Ochetosomatidae (Dasymetra, Pneumatophilus, Renifer, Neorenifer), Plagiorchiidae (Leptophyllum, Paurophyllum, Stomatrema, Styphlodora), Proterodiplostomidae (Pseudoneodiplostomum, Pseudocrocodilicola), Spirorchiidae (Spirorchis, Henotosoma, Vasotrema, Unicaecum, Hapalorhynchus), Telorchiidae (Cercorchis); the Nematoda are represented by the Diaphanocephalidae (Kalicephalus). No attempt was made to determine current generic status or synonymies.

Inheritance of colour and coat in the Belgian Shepherd dog

The several colours and coats of the Belgian Shepherd dog are shown to be due primary to combinations of the following genes: dominant black (A ^s ), dominant yellow (A ^y ), chinchilla (ch), long hair (l) and wire hair (Wh). The gene for black and tan (a ^t ) is or has been present in the breed. All of the dominant yellow dogs exhibit a black facial mask and extensive suffusion of black guard hairs on the body.     

A short review on dermatophytoses of animals in Romania

Dermatophytoses of animals in Romania are reviewed. Ringworm infections have been found in cattle (whereT. verrucosum was the only isolated agent), horses (the causative organisms beingT. verrucosum, T. mentagrophytes andM. equinum), cats (dermatophytes isolated:M. canis andT. quinckeanum), dogs (M. canis andM. gypseum), fowlsT. gallinae). From the laboratory animals: guinea pigs (T. mentagrophytes, M. audouinii, T. rubrum), mice (T. quickeanum andT. mentagrophytes), rats (T. mentagrophytes), rabbits (T. mentagrophytes andM. canis) and hamster)T. mentagrophytes). Among the wild animals, only the chamois had a ringworm infection byM. gypseum, other large or smaller wild animals harboring only saprophytically some poozhilic and geophilic dermatophytes.     

Sublethal effects of Thymus vulgaris essential oil on life-table parameters of two-spotted spider mite,Tetranychus urticae Koch (Acari: Tetranychidae)

Sublethal effects of Thymus vulgaris were investigated on life-table parameters of Tetranychus urticae Koch (Acari: Tetranychidae) in the laboratory conditions at 25?±?1?°C, 70?±?10% RH and a 14:10?h (L:D) photoperiod. Bioassay was conducted to assess the effect of different concentrations of T. vulgaris essential oil on two-spotted spider mite. LC₅₀ and LC₂₀ of T. vulgaris on T. urticae were calculated as 18.86 and 6.24?μl/litre air for 24?h after treatment. In the sublethal effects, after 24?h exposure to LC₅₀ concentration, mortality, fecundity and longevity of the females that survived from treatment were determined. Results showed that T. vulgaris caused significant reductions in fecundity and longevity of adults. Life-table assay indicated that the intrinsic rate of increase (r _m), net reproductive rate (R ₀), finite rate of increase (λ), mean generation time (T), significantly reduced in treated females compared to control. These results suggest that T. vulgaris could be incorporated in integrated pest management programmes of T. urticae.
