Query: NC_011982:206784 Agrobacterium vitis S4 plasmid pTiS4, complete sequence
Lineage: Agrobacterium vitis; Agrobacterium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Agrobacterium vitis is the causative agent of crown gall disease in grapes. Agrobacterium are Gram-negative, motile, soil-dwelling plant pathogens with the species name given based on the disease phenotype associated with the bacteria. Disease causing Agrobacterium spp. possess a tumor-inducing (Ti) plasmid, which carries genes for the formation of opines. A segment of the Ti plasmid gets transferred to the plant cell and integrates into the host cell genome. The plant cell then starts synthesizing opines, which can be catabolized by Agrobacterium spp, but not by the plant cells.
Subject: NC_010125:333895 Gluconacetobacter diazotrophicus PAl 5, complete genome
Lineage: Gluconacetobacter diazotrophicus; Gluconacetobacter; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Gluconacetobacter diazotrophicus strain PAL5 (ATCC 49037) was isolated from sugarcane roots in Brazil and will be used for comparative analysis. Nitrogen-fixing plant symbiont. This acid-tolerant organism is endophytic and colonizes internal plant tissues, establishing a symbiotic relationship with its host. This bacterium has been found in sugarcane, coffee, rice, tea, and other plants. The nitrogen-fixation systems of the bacterium provide the plant with essential nitrogenous compounds while the plant provides a protected environment for the bacterium to grow in. Nitrogen-fixation is important for sugarcane production, and this organism can fix nitrogen even in the presence of nitrate.
