A novel repressor for expression of a type 6 protein secretion system links nitrogen signaling with beneficial plant-microbe interactions

(Submitter supplied) To investigate the regulon of the novel transcriptional regulator TssR discovered in our study We then performed gene expression profiling analysis using data obtained from RNA-seq of wild type Azoarcus olearius sp. BH72 and tssR deleted mutant cultured under microaerobic conditions with additional ammonium

RNA-Seq provides new insights into the nitrogen response of Azoarcus olearius BH72 during N2-fixation beyond the nitrogen fixation process

(Submitter supplied) Azoarcus olearius BH72 is a diazotrophic endophyte carrying out biological nitrogen fixation (BNF) and supplying nitrogen to its host plant. Our previous microarray approach provided insights in the transcriptome of strain BH72 under N2-fixation in comparison to ammonium-grown conditions, which already indicated induction of genes not related to the BNF process. Due to the known limitations of the technique, we might have missed additional differentially regulated genes (DEGs). more...

Transcriptome profile of wild type Azoarcus sp. BH72 grown under microaerobic condition (0.3% oxygen) compared with that grown under aerobic condition (21% oxygen), both in presence of combined nitrogen source, respectively

(Submitter supplied) Low oxygen tensions are often encountered in flooded soils of rice fields by root-associated, strictly respiratory, beta proteobacterium, Azoarcus sp. BH72 which fixes nitrogen only under microaerobic condition. In this study, genome wide oligonucleotide microarrays were used compare the global transcription profile of Azoarcus sp. BH72 under microaerobic condition with cells grown under aerobic condition, both with ammonia as sole nitrogen source. more...

Transcriptome comparison of the wild type strain Azoarcus sp. BH72 with that of nifLA knockout strain under nitrogen fixing condition

(Submitter supplied) Azoarcus sp. BH72 is known to express nitrogenase genes endophytically in rice seedlings in gnotobiotic culture. Availability of fixed nitrogen is one of the important signals regulating the transcription of nitrogenase genes and hence nitrogen fixing activity. NifA is the essential transcription activator of nif genes. RNA isolated from the nifA knockout mutant of strain BH72 was compared with the transcriptome of wild type under nitrogen fixing condition using a global genome wide microarray approach and the differences in the gene expression profile were monitered.

Transcriptome comparison of wild type Azoarcus sp. strain BH72 grown under nitrogen fixation (experiment) with cells grown with combined nitrogen (ammonia) as nitrogen source

(Submitter supplied) Model endophyte Azoarcus sp. BH72 is known to contribute fixed nitrogen to its host Kallar grass by nitrogen fixation and also expresses nitrogenase genes endophytically in rice seedlings in gnotobiotic culture. Availability of fixed nitrogen is one of the important signals regulating the transcription of nitrogenase genes and hence nitrogen fixing activity. Therefore, we analysed global transcription in response to differences in the nitrogen source. more...

Transcriptomic analysis of responses to exudates reveal genes required for rhizosphere competence of the endophyte Azoarcus sp. strain BH72.

(Submitter supplied) Endophytic colonization is a very complex process which is not yet completely understood. Molecules exuded by the plants may act as signals which influence the ability of the microbe to colonize the host or survive in the rhizosphere. Here we investigated whether root exudates of the host might play a role in initiating the endophyte-rice interaction. The whole genome microarray approach was used to investigate the response of the diazotrophic model endophyte, Azoarcus sp. more...

Characterization of cell density-regulated gene expression of the grass endophyte Azoarcus sp. BH72

(Submitter supplied) Azoarcus sp. BH72 is able to communicate via cell density-dependent gene regulation. Here, the impact of cell-free conditioned culture supernatants, obtained from stationary phase Azoarcus wild type cultures, on gene expression was investigated determining changes in transcript profiles when early exponential aerobic cultures were incubated with cell-free culture supernatants for one and four hours. more...

Azoarcus sp. BH72 Array

(Submitter supplied) The Azoarcus microarray was designed by spotting gene-specific 70mer oligonucleotides (manufactured by Eurofins MWG GmbH) in quadruplicates onto epoxy-coated glass slides representing 3992 predicted protein-coding genes of Azoarcus sp. Strain BH72. Each oligonucleotide (40 µM) was spotted in 1.5 M betaine/450 mM sodium chloride/45 mM sodium citrate (pH 7).
