The genome of the strain Sp245, isolated in Brazil from wheat roots, consists of one chromosome and six plasmids. This site needs JavaScript to work properly. Sp245T and its close relatives to other Azospirillum species type strains, such as A. brasilense Sp7T and A. formosense CC-Nfb-7T , revealed values lower than the limit of species circumscription. Azospirillum brasilense Sp245 was reported to harbor two functional nirK genes on different replicons . 2013 Nov;49(11):1270-5. We studied changes in the physiological and biochemical parameters of wheat ( Triticum aestivum L. âSaratovskaya 29â) seedlings treated with lipopolysaccharide isolated from the outer membrane of the associative bacterium Azospirillum brasilense Sp245.

A. brasilense is able to fix nitrogen in the presence of low oxygen levels, making it a microaerobic diazotroph. No study has been carried out to uncover these regulatory molecules in the diazotrophic alpha-proteobacterium Azospirillum brasilense Sp245 to date. It is considered a free-living soil bacterium that has the ability to affect the growth of numerous agricultural crops worldwide through the excretion of various hormones and the bacteria’s ability of nitrogen fixation. Clipboard, Search History, and several other advanced features are temporarily unavailable. Azospirillum brasilense is one of the most well-studied plant growth promoting bacteria. Azospirillum brasilense is a well studied, nitrogen-fixing (diazotroph), genetically tractable, Gram-negative, alpha-proteobacterium bacterium, first described in Brazil (in a publication in 1978) by the group of Johanna Döbereiner and then receiving the name "brasilense". The genome of Azospirillum brasilense encodes five RpoH sigma factors: two OxyR transcription regulators and three catalases. Sp245T, a finding that was corroborated by the genome clustering of OGRI values and housekeeping phylogenies. Int J Syst Evol Microbiol. An antimicrobial compound was isolated from Azospirillum brasilense culture extracts by high-performance liquid chromatography and further identified by gas chromatography-mass spectrometry as the auxin-like molecule, phenylacetic acid (PAA).
