Complete genome sequencing of the gammaproteobacterial endosymbiont of the scaly-foot gastropod (aka “kurosuke”), an armored snail that lives in deep-sea vents
Research Press Release | September 13, 2013
|Key Points||– The successful analysis of the complete genome sequence of the gammaproteobacterial endosymbiont that provides life-support for scaly-foot gastropods.
– The identification of the principal metabolic pathways and unique evolutionary process of the endosymbiont via genome analysis and incubation experiments.
– The determination of the endosymbiont’s mode of transmission from a genetic comparison of individual gastropods collected from a single colony.
– An understanding of the scaly-foot gastropod’s sensitive environmental response using the same methods as human blood tests.
|Overview||In addition to the complete genome sequencing of the gammaproteobacterial endosymbiont of the scaly-foot gastropod, a unique snail with mineralized scales, and the comprehensive identification of its metabolic pathways, the endosymbiont’s mode of transmission was determined.
In addition, an understanding was gained of the scaly-foot gastropod’s sensitive environmental reception and response.
This study is the first to clarify at the genetic level the survival tactics that the scaly-foot gastropod and gammaproteobacterial endosymbiont have evolved in order to survive in deep-sea vents.
It is expected to serve as a foundation for further advances in the study of the scaly-foot gastropod, a snail about which much still remains unknown.
