Mitogenome Diversity and Maternal Origins of Guangxi Cattle Breeds.

ABSTRACT: Guangxi Province is located in the southernmost region of China, adjacent to the hotspot that is considered to be the putative migratory corridor or domestication area for Chinese indicine cattle. Here, we investigated the evolutionary status of Guangxi native breeds, Longlin (n = 21), Nandan (n = 18), and Weizhou cattle (n = 17) using mitogenome sequencing. Our results show that Bos indicus sub-haplogroup I1a predominates in Guangxi cattle breeds. Population structure by multidimensional-scaling analysis significantly differentiates Weizhou from the other two breeds (Longlin and Nandan). Moreover, the mtDNA haplotype composition and F_ST values indicate that the formation of Longlin and Nandan breeds may have been affected by Indian indicine, w
