Identification and characterization of a flagellin gene from the endosymbiont of the hydrothermal vent tubeworm Riftia pachyptila

Article Abstract:

The bacterial endosymbionts of the hydrothermal vent tubeworm Riftia pachyptila play a major role in furnishing their host with fixed carbon. Findings of previous research indicate that the symbionts are chosen from an environmental bacterial population, even though a free-living form has been neither cultured from nor identified in the hydrothermal vent environment. A flagellin gene from a symbiont fosmid library was cloned and characterized to evaluate the free-living potential of the symbiont. Findings gave the first evidence of a motile free-living stage of a chemoautotrophic symbiont and support the hypothesis that the symbiont of R. pachyptila is obtained with each new host generation.

A histidine protein kinase homolog from the Endosymbiont of the hydrothermal vent tubeworm Riftia pachyptila

Article Abstract:

Microbiological research indicates that uncultivated bacterial endosymbionts of the hydrothermal vent tubeworm Riftia pachyptila use a phosphotransfer signal transduction pathway to pass on fixed carbon to the host organism. Genetic cloning techniques were used to encode the bacterial gene to express Riftia symbiont signal kinase. Further research is required to establish exactly how details on the communication of signal transduction proteins in the symbiont.

Fate of nitrate acquired by the tubeworm Riftia pachyptila

Article Abstract:

Research has been conducted on the tubeworm Riftia pachyptila. Results indicate that ammonia and nitrate elimination by R. pachyptila occurs at low rates.
