Project description: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. Examination of transcriptome profile of rhizobacterium B. amyloliquefaciens FZB42 grown under six conditions.
Project description:We report the application of a high-throughput technique, RNA-seq, to study the transcriptomic response of P. chlororaphis and Bacillus amyloliquefaciens growing in co-cultures in King B solid medium
Project description:Transcription profiling by array of Bacillus amyloliquefaciens strain FZB42 after soil extract treatment, at OD600=1.0 and OD600=3.0 respectively.

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.
Project description:We report the banana transcriptome profile in response to two distinct growth-promoting rhizobacteria, Bacillus amyloliquefaciens and Pseudomonas fluorescens. The goal of our study is to identify plant genes differentially regulated by rhizobacteria-plant interaction along time. At the same time, we show that despite these two rhizobacteria regulate distinct sets of genes, the same functional categories has been over-represented, such as transcription factor activity, response to stress and metabolic processes.
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.
