Integrated multi-approaches reveal unique metabolic mechanisms of Vestimentifera to adapt to deep sea.

ABSTRACT:

Background

Vestimentiferan tubeworms are deep-sea colonizers, in which chemoautotrophic symbiosis was first observed. These animals are gutless and depend on endosymbiotic bacteria for organic compound synthesis and nutrition supply. Taxonomically, vestimentiferans belong to Siboglinidae and Annelida. Compared with other siboglinids, vestimentiferans are distinguished by high tolerance of the prevailing hydrogen sulfide in hydrothermal vents, rapid growth in local habitats, and a physical structure consisting of a thick chitinous tube. The metabolic mechanisms contributing to these features remain elusive.

Results

Comparative genomics revealed that unlike other annelids, vestimentiferans possessed trehaloneogenesis and lacked gluconeogenesis. Transcriptome and metabolome ana
