Abstract |
To search the evidence of molecular evolution mechanism for aquatic and cave habitat inAndrias davidianus, the evolution analysis was carried out among several species transcriptome data. The transcriptome data ofNotophthalmus viridescens,Xenopus tropicalis, Cynops pyrrhogaster, Hynobius chinensisandA. davidianuswere obtained from the Genbank and reassembled exceptXenopus tropicalis. The BLAST search of transcriptome data obtained 1244 single-copy orthologous genes among five species.A phylogenetic tree showedA. davidianusto have the closest relationship toH. chinensis. Fourteen positively selected genes were detected inA. davidianusandN. vridescensgroup and fifteen inA. davidianusandH. chinensisgroup. Five genes were shared in the both groups which involved in the immune system, suggesting thatA. davidianusadaptation to an aquatic and cave environment required rapid evolution of the immune system compared toN. viridescensandH. chinensis. |
