Effect of deletion of all0854 on gene expression of Nostoc sp. PCC 7120

Project description:To investigate the function of All0854, we constructed the all0854 deletion mutant Mall0854, in which all0854 was knocked out by CRISPER-cpf1. We then performed gene expression profiling analysis using data obtained from RNA-seq of wide type Nostoc sp. PCC 7120 and Mall0854.

Nitrogen-regulated antisense transcription in the adaptation to nitrogen deficiency in Nostoc sp. PCC 7120

Project description:Transcriptomic analyses using high-throughput methods have revealed abundant antisense transcription in bacteria. Most frequently, antisense transcription is due to the overlap of mRNAs with long 5’ regions or 3’ ends that extend beyond the coding sequence. In addition, antisense RNAs that do not contain any coding sequence are also observed. Nostoc sp. PCC 7120 is a filamentous cyanobacterium that, under nitrogen limitation, behaves as a multicellular organism with division of labor among two different cell types that depend on each other, the vegetative CO2-fixing cells and the nitrogen-fixing heterocysts. Differentiation of heterocysts depends on the global nitrogen regulator NtcA and requires the specific regulator HetR. To identify antisense RNAs potentially involved in heterocyst differentiation we performed an RNA-Seq analysis of cells subjected to nitrogen limitation (either at 9 or 24 hours after nitrogen removal) and analyzed the results in combination with a genome-wide set of nitrogen-regulated transcriptional start sites and a prediction of transcriptional terminators. Our analysis resulted in the definition of a transcriptional map including more than 4,000 transcripts, 65% of them in antisense orientation to other transcripts. In addition to overlapping mRNAs we identified nitrogen-regulated non-coding antisense RNAs transcribed from NtcA-dependent or HetR-dependent promoters.

Emergence of essential functions of a transcription factor in the cyanobacterium Nostoc/Anabaena sp. PCC 7120 [ChIP-seq]

Project description:How new functions emerge as genes diversify during evolution is an important question in biology. cyclic adenosine monophosphate receptor protein (CRP) -type transcription factors are widespread in bacteria, often with several members coexisting in the same organism. How do they achieve functional specificity with highly conserved structures? In the filamentous cyanobacterium Nostoc/Anabaena sp. PCC 7120, both NtcA and DevH belong to the CRP family, yet DevH is essential while NtcA is not. Together with previously published data, we demonstrate here that ntcA and devH mutually and positively regulate each other for enhanced expression. Furthermore, NtcA and DevH share a common consensus DNA binding site, and both of them exert global regulation functions for metabolism, photosynthesis and cell development. We show that compared to NtcA, DevH achieved functional specificity and essentiality by structural innovations and increased cellular concentrations, leading to a stronger and broader regulatory function independent of allosteric control. Based on our data, we propose a model on how these two conserved transcription factors provide both overlapping and distinct regulatory functions, to better coordinate transcriptional activities under different conditions. This study constitutes an example illustrating how functional divergence can be achieved following gene diversification of transcription factors, leading to increased complexity in gene regulation networks.
