Forensic Analysis and Genetic Structure Construction of Chinese Chongming Island Han Based on Y Chromosome STRs and SNPs.

Y-chromosome short tandem repeat (Y-STR) and Y-chromosome single nucleotide polymorphism (Y-SNP) are genetic markers on the male Y chromosome for individual identification, forensic applications, and paternal genetic history analysis. In this study we successfully genotyped 38 Y-STR loci and 24 Y-SNP loci of Pudong Han ( = 689) and Chongming Han ( = 530) in Shanghai. The haplotype diversity of the Y filer platinum genotyping system was the highest in the Han population in the Pudong area of Shanghai (0.

Persistence of Metarhizium (Hypocreales: Clavicipitaceae) and Beauveria bassiana (Hypocreales: Clavicipitaceae) in Tobacco Soils and Potential as Biocontrol Agents of Spodoptera litura (Lepidoptera: Noctuidae).

Entomopathogenic fungi (EPF), such as Metarhizium spp. and Beauveria bassiana, are widely used in the biocontrol of many species of insect pests. Tobacco is an economically important crop in Guangdong Province of China, but insect pests, such as Spodoptera litura Fabricius, are a major threat to production.

A Comparison of Genetic Diversity of COX-III Gene in Lowland Chickens and Tibetan Chickens.

To obtain a full understanding of the genetic diversity of the cytochrome oxidase III gene and its association with high altitude adaptation in Tibetan chickens, we sequenced in 12 chicken populations (155 Tibetan chickens and 145 other domestic chickens). We identified a total of 11 single nucleotide polymorphisms (SNPs) and 12 haplotypes (Ha1-Ha12). Low genetic diversity (haplotype diversity = 0.
