BACKGROUND Many of the processes affecting genetic diversity act on local populations. However, studies of plant nucleotide diversity have largely ignored local sampling, making it difficult to infer the demographic history of populations and to assess the importance of local adaptation. Arabidopsis lyrata, a self-incompatible, perennial species with a circumpolar distribution, is an excellent ...

Meconopsis horridula is one of the eight most famous flowers in Chinese province of Yunnan. In this study, a modified biotin-streptavidin capture method was used to detect 13 microsatellite markers in the genome of M. horridula. The polymorphism of each locus was assessed in 24 samples collected from four populations. The number of alleles per locus ranged from 2 to 7 (mean: 3.2). The observed ...

The present study was carried out to validate the single nucleotide polymorphism (SNP) in mitochondrial gene- cytochrome b oxidase at 14,716 bp (C T transition) position obtained from whole genome sequence data of indigenous cattle breeds Department Animal Genetics and Breeding, Madras Veterinary College, Tamil Nadu. A total 288 animals, viz. Alambadi (16), Bargur (99), Kangayam (54), Pulikulam...

Osteosarcoma is one of the most common bone malignancies in adolescents, and hereditary factors may influence its susceptibility. We assessed the association between XRCC3 Thr241Met polymorphism and susceptibility to osteosarcoma in a Chinese population. Between May 2012 and May 2014, a total of 136 osteosarcoma patients and 136 healthy control subjects were included in our study. The XRCC3 Thr...

molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. the insulin like growth factor-i (igf-i) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. the objectives of the present study were the estimate the haplotype frequencies of the igf-i gene polymorphisms i...

OBJECTIVE The objective of the current study was to examine the relationship between the COMT Val(158)Met polymorphism and neuropsychological performance in depressed and nondepressed older adults. METHODS One hundred and twenty-six clinically depressed older adults and 105 nondepressed comparison participants were compared on neuropsychological performance and COMT Val(158)Met (Val/Val, Val/...

BACKGROUND The prediction of the genetic disease risk of an individual is a powerful public health tool. While predicting risk has been successful in diseases which follow simple Mendelian inheritance, it has proven challenging in complex diseases for which a large number of loci contribute to the genetic variance. The large numbers of single nucleotide polymorphisms now available provide new o...

The genomic revolution has generated an extraordinary resource, the catalog of variation within the human genome, for investigating biological, evolutionary and medical questions. Together with new, more efficient platforms for high-throughput genotyping, it is possible to begin to dissect genetic contributions to complex trait diseases, specifically examining common variants, such as the singl...
