新疆马鹿群体遗传多样性及起源进化研究
Genetic Diversity, Origin and Evolution of Wapiti (Red Deer) in Xinjiang
摘要
Abstract
In order to explore the genetic diversity and classification status of wapiti (red deer) in Xinjiang and provide the basis research materials for the scientific protection and utilization of red deer,the whole D-loop sequences (896-999 bp) of five subspecies wapiti (Talim wapiti,Altai wapiti,Tianshan wapiti,Gansu wapiti and Alashan wapiti)in 108 samples were amplified and sequenced,the base composition and nucleotide sequence variation were analyzed.Results showed that there were 40 different haplotypes,the haplotype diversity (Hd) was 0.998±0.006,nucleotide difference (pi) was 0.041±0.005,Average number of nucleotide difference(K) was 36.08.The NJ and MP phylogenetic tree showed that Talim wapiti had further genetic distance with other subspecies,they should be clustered in different wapititypes;the gene exchange were found in Altai wapiti,Tianshan wapiti and Gansu wapiti,probably due to the hybridization caused by introduction in different population.It was concluded that there were abundant genetic diversity in wapiti in Xinjiang;Talim red deer might originated in Europe;other population originated in Asia ; gene exchange were found in different populations.关键词
