英文摘要Deep-sea hydrothermal vent is one of the most extreme environments on Earth with low oxygen and high levels of toxins. Decapod species from the family Alvinocarididae have colonized and successfully adapted to this extremely harsh environment. Mitochondria plays a vital role in oxygen usage and energy metabolism, thus it may be under selection in the adaptive evolution of the hydrothermal vent shrimps. In this study, the mitochondrial genome (mitogenome) of alvinocaridid shrimp Shinkaicaris leurokolos (Kikuchi & Hashimoto, 2000) was determined through Illumina sequencing. The mitogenome of S. leurokolos was 15,903 bp in length, containing 13 protein-coding genes, 2 rRNAs, and 22 tRNAs. The gene order and orientation were identical to those of sequenced alvinocaridids. It has the longest concatenated sequences of protein-coding genes, tRNAs and shortest pooled rRNAs among the alvinocaridids. The control regions (CRs) of alvinocaridid were significantly longer (p < 0.01) than those of the other caridaen. The alignment of the alvinocaridid CRs revealed two conserved sequence blocks (CSBs), and each of the CSBs included a noncanonical open reading frame (ORE), which may be involved in adjusting mitochondrial energy metabolism to adapt to the hydrothermal environment. Phylogenetic analysis supported that the deep-sea hydrothermal vent shrimps may have originated from those living in shallow area. Positive selection analysis reveals the evidence of adaptive change in the mitogenome of Alvinocarididae. Thirty potentially important adaptive residues were identified, which were located in atp6, coxl, cox3, cytb and nadl-5. This study explores the mitochondria] genetic basis of hydrothermal vent adaptation in alvinocaridid for the first time, and provides valuable clues regarding the adaptation.
