Query: NC_012880:3915500 Dickeya dadantii Ech703, complete genome
Lineage: Dickeya dadantii; Dickeya; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Temp: Mesophile. Dickeya dadantii formerly (Erwinia chrysanthemi) is a phytopathogenic bacterium that causes soft rot diseases on many crops. This organism produces pectinolytic enzymes which break down plant cell walls allowing for the spread of disease.
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.
