Differential RNA-seq of Plant Beneficial Rhizobacterium Bacillus amyloliquefaciens FZB42 Reveals sRNA Bas01 involved in Sporulation and Biofilm Formation

ABSTRACT: Bacillus amyloliquefaciens FZB42 is a representative organism for Gram positive soil bacteria associated with plant roots and beneficial to plant growth. It is of immense importance to understand mechanisms of this class of bacteria adapting to rhizosphere. In this work employing differential RNA sequencing (RNA-seq) and Northern blot, we systematically identified transcription start sites of mRNAs as well as non-coding regulatory RNAs in FZB42. The genes regulated at different growth phases and located in polycistronic operons were also identified. A set of genes were re-annotated. In addition, a sRNA named Bas01 was identified to be involved in Bacillus sporulation and biofilm formation. The result we obtained provides valuable data for investigation of Bacillus gene expression and molecular details of rhizobacterial interaction with host plants.

Acetylome analysis of Bacillus amyloliquefaciens

Project description:Lysine acetylation is a major post-translational modification that plays an important regulatory role in almost every aspects in both eukaryotes and prokaryotes. Bacillus amyloliquefaciens, a Gram-positive bacterium, is very effective for the control of plant pathogens. Here, we conducted the first lysine acetylome in B. amyloliquefaciens through a combination of highly sensitive immune-affinity purification and high-resolution LC−MS/MS. Overall, we identified 3268 lysine acetylation sites in 1254 proteins. Acetylated proteins are associated with a variety of biological processes and a large fraction of these proteins are involved in metabolism. These data serves as an important resource for further elucidation of the physiological role of lysine acetylation in B. amyloliquefaciens.

Transcriptomics of Bacillus amyloliquefaciens SQR9 to maize root exudates

Project description:Root exudates play an important role in plant-microbe interaction. The transcriptional profilings of plant growth-promoting rhizobacteria Bacillus amyloliquefaciens SQR9 in response to maize root exudates under static condition, were investigated by an Illumina RNA-seq for understanding the regulatory roles of the root exudates. 4 treatments, including 2 blank control (24 h and 48 h-post inoculation, named as 5 and 15, respectively), and 2 treatments with maize root exudates (24 h and 48 h-post inoculation, named as 7 and 17, respectively)

Transcription profiling by array of Bacillus amyloliquefaciens FZB42 wildtype and sigD- mutants grown in media supplemented with soil extract

Project description:Bacillus amyloliquefaciens FZB42 is a well-studied Gram-positive plant growth-promoting rhizobacteria. In this work we aim to study the effect of the effect of sigD deletion on the transcriptome of FZB42. The transcritomes were compared by two-color microarray of the sigD- mutant and the wildtype of B. amyloliquefaciens FZB42 grown in 1C medium supplemented with soil extract (SE). This submission includes data from two independent experiments with three biological replicates. Here a biological replicate means the bacterial culture from one flask used for RNA preparation. The samples were collected by two performers. The experiments were varied in sample performer, the date of the experiment.

RNA-Seq gene expression profiling in the plant growth promoting Bacillus atrophaeus UCMB-5137 revealed an alternative strategy of plant colonization compared to Bacillus amyloliquefaciens endophytes

Project description:Plant growth promoting rhizobacteria (PGPR) of the genus Bacillus are successfully used as biofertilizers and biopesticides. They potentially can reduce the use of chemicals in agriculture as an ecologically safe alternative, but to optimize the application of PGPR, more profound knowledge on specific gene regulation and molecular mechanisms of interaction with plants is needed. Advance in sequencing technologies made it affordable to compare transcriptom profiles of relative organisms to check to which extend PGPR strains or closely related species differ in their strategies of plant colonization. This work aimed at analysis of gene regulation in a biotechnological strain Bacillus atrophaeus UCMB-5137 to compare it with the gene expression profile of a generally recognized PGPR strain B. amyloliquefaciens FZB42. It was found out that despite the close taxonomic relatedness, these two organisms developed ability to colonize plants independently and use different strategies of plant colonization. Root exudate has triggered in UCMB-5137 alteration in expression in many genes controlled by stress response transcription factors (TF) SigB and SigD, while SigF, SigH, SigW, CcpA and several other TFs regulated genes associated with quorum sensing and biofilm formation, and adjusted the carbohydrate metabolism. Counting to peculiarities of gene regulation in different PGPR strains will allow optimization of their practical application.
