Query: NS_000191:120700 Uncultured Termite group 1 bacterium phylotype Rs-D17, complete
Lineage: uncultured Termite group 1 bacterium; enviromental sample; ; ; Elusimicrobia; Bacteria
General Information: Termite gut symbion. Termites harbor a symbiotic gut microbial community that is responsible for their ability to thrive on recalcitrant plant matter. Found specifically within the cells of the cellulolytic flagellate Trichonympha agilis in the gut of the termite Reticulitermes speratus.
Subject: NC_008043:167108 Silicibacter sp. TM1040 mega plasmid, complete sequence
Lineage: Ruegeria; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This strain was isolated from a culture of the dinoflagellate Pfiesteria piscicida CCMP1830 which has been implicated in many large scale algal blooms resulting in increased mortality in fish. The bacteria are attached to the surface of the dinoflagellate and in some ways allow the dinoflagellate to grow as those lacking the bacteria die off. The bacterium also chemotaxes towards the dinoflagellate product DMSP (dimethylsulfoniopropionate) and metabolizes it. DMSP is a major source of sulfur in marine ecosystems and plays a role in the sulfur biogeochemical cycle. The implication is a tight association between these important dinoflagellates and this marine bacterium.
