ABSTRACT Chinese indigenous chicken breeds are geographically widespread, and a total of 116 indigenous chicken breeds are listed as Chinese national genetic resources. However, these indigenous chicken breeds are facing serious challenges as declining population and germplasm degeneration because lots of commercial chicken breeds had been introduced. In this study, the genetic variations of eleven Chinese indigenous chicken breeds of Sichuan province and three commercial chicken breeds were investigated based on the partial mitochondrial DNA D-loop of 487bp in length. 147 individuals from 14 breeds were examined and 34 haplotypes were observed. Genetic diversity analysis showed that the highest haplotype diversity level was found in Dahen Chicken (DH)...

Variations in Tissue-Specific Expression of Adipose Differentiation-Related Protein Gene in Two Native Yunnan Chicken Breeds 89
Zhang,B; Xiang,D; Yang,R; Yang,L; Li,J; Zhao,Z.
ABSTRACT Adipose differentiation-related protein (ADFP) is a fatty acid-binding protein that can promote the absorption of long-chain fatty acids. However, few results have been published regarding its role in Yunnan Native chicken breeds. The aim of this study was to determine ADFP gene tissue-specific expression in Piao chickens (PC) and Wuliangshan black-bone chickens (WBC) by RT-qPCR. The ontogenetic expression levels of the ADFP gene were significantly different during growth and development phases in the subcutaneous fat, liver, and pectoralis muscle of PC, and in the subcutaneous fat, liver, and pectoralis muscle of WBC (p<0.05). Individual tissue-differential expression levelswere detectedon d 91 and 112 in PC, with highest levels determined in...
