Unique variations of SRY gene result in distinct patrilineal phylogeny of Capra hircus and other domestic Bovidae
Journal Title: Animal Science Papers and Reports - Year 2013, Vol 31, Issue 3
Abstract
Patrilineal phylogeny of Beichuan White goat and other domestic Bovidae was inferred from 5ยด- UTR and coding region of SRY gene. Variation analysis revealed 208 variable sites, meanwhile, a 50-bp fragment inserted downstream of the initiation codon (ATG) of SRY genes modified the translational initiation process in Bos and Bubalus, while the mechanism of what should be explained in a further study. Amino acid sequence alignments of HMG-box region indicated a high degree of conservation among goats and other Bovidae. All the sequences of Bovidae clustered into Bos, Bubalus and Capra. Bos indicus, Bos taurus, Bos javanicus, Bos frontalis, Bos grunniens and Bison bonasus were comprised in genus Bos, while Bubalus bubalis and Syncerus caffer belonged to genus Bubalus. Beichuan white goats and other Capra hircus specimens were clustered into genus Capra. Patrilineal phylogeny of Bovidae exhibited a discrepancy from the earlier matrilineal analysis.
