Mitochondrial haplotypes influence metabolic traits across bovine inter- and intra-species cybrids.

ABSTRACT: In bovine species, mitochondrial DNA polymorphisms and their correlation to productive or reproductive performances have been widely reported across breeds and individuals. However, experimental evidence of this correlation has never been provided. In order to identify differences among bovine mtDNA haplotypes, transmitochondrial cybrids were generated, with the nucleus from MAC-T cell line, derived from a Holstein dairy cow (Bos taurus) and mitochondria from either primary cell line derived from a domestic Chinese native beef Luxi cattle breed or central Asian domestic yak (Bos grunniens). Yak primary cells illustrated a stronger metabolic capacity than that of Luxi. However, all yak cybrid parameters illustrated a drop in relative yak mtDNA compared to Luxi mtDNA, in line with a mitonucl
