Veterinarians have recognised a nonpruritic skin disease in the Golden retriever breed characterised by excessive scaling of large, variably pigmented flakes of skin in otherwise healthy dogs. This prospective case series describes clinical, histopathological, ultrastructural and genetic features of this cornification defect in 17 affected dogs. The condition affects young dogs of either sex and is characterised by symmetrical, predominantly ventro-lateral scaling and hyperpigmentation of the trunk. Histopathological and ultrastructural changes of the stratum corneum are suggestive of delayed degradation of corneodesmosomes. A genetic aetiology is proposed and a single-trait autosomal recessive mode of inheritance discussed. 相似文献

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species. 相似文献

Mungbean (V. radiata) is an important Asiatic legume supplying inexpensive protein to a vast majority of vegetarian masses. To increase markers repertoire in mungbean, a study was conducted to analyse 384 microsatellite markers derived from common bean, scarlet runner bean and adzuki bean for their transferability and polymorphism. The results showed that 87 (24.71%) primer pairs could amplify DNA loci of 20 mungbean genotypes including one accession of V. trilobata, while 52 showed reliable banding and polymorphism. These showed different degrees of variability at each locus producing 250 alleles with the number of alleles varying from 2 to 9. The major allele frequency varied from 0.17 to 0.95, while the polymorphic information content of SSRs ranged between 0.09 and 0.86 with an average of 0.60 ± 0.16. UPGMA revealed three major clusters accommodating ~95% of the accessions while one accession of V. trilobata (‘NSB‐007’) did not group with any other genotype describing the discriminating power of informative microsatellites. This study identified a set of useful microsatellite markers to accelerate the genetic studies and breeding programme of mungbean. 相似文献
