Query: NC_013854:3126385 Azospirillum sp. B510, complete genome
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_011059:1 Prosthecochloris aestuarii DSM 271, complete genome
Lineage: Prosthecochloris aestuarii; Prosthecochloris; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: This species is a green sulfur bacterium which forms sedimentary biofilm layers. It has been shown to be associated with coral killed by Black-Band Disease (BBD) a microbial infection of larger coral species. This is a concern for reef conservationists as the larger species are responsible for coral scaffolds, and their reduction by disease would have considerable impact on the reef structure. While there is currently no cause-and-effect link between Prosthecochloris aestuarii and BBD, the species was found on coral which was killed by the disease and was not found on healthy coral or in the surrounding seawater.
