Query: NC_013859:9500 Azospirillum sp. B510 plasmid pAB510e, complete sequence
Lineage: Azospirillum; Azospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Azospirillum are commonly isolated from the rhizosphere and root surfaces from a wide variety of plants. Azospirillum species are considered to be plant growth promoting organisms, producing plant hormones for cell elongation (auxins), cell division and growth (cytokinins) and stem elongation (gibberellins). These compounds contribute to an enhanced uptake of nutrients and water and thus increased plant growth. Azospirillum sp. B510 was isolated from rice in Japan.
Subject: NC_010125:2998619 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.
