(Submitter supplied) Transcriptomic analysis of suspended and flocculated (with the fungi) Synechocystis cells suggested that the EM-mediated co-flocculation was a result of down-regulation of the minor pilin genes and up-regulation of several genes including the chaperone gene for pilin regulation, the S-layer protein genes, the exopolysaccharide-polymerization gene, and the genes for signaling proteins involved in cell attachment and abiotic-stress responses. more...

(Submitter supplied) Photoautotrophic cyanobacteria assimilate the greenhouse gas carbon dioxide as their sole carbon source for producing useful bioproducts. However, harvesting the cells from their liquid media is a major bottleneck in the process. Thus, an easy-to-harvest method, such as auto-flocculation, is desirable. Here, we found that cyanobacterium Synechocystis sp. PCC 6803 co-flocculated with a natural fungal contamination in the presence of the antibiotic erythromycin (EM) but not without EM. more...

(Submitter supplied) Microarray analysis demonstrated that the expression levels of minor pilin genes change in response to surface contact. A total of 120 genes were determined to have altered transcription between planktonic and surface growth in this analysis. Among these genes, 13 are located on the pSYSM plasmid, and some are newly predicted minor pilin genes.

(Submitter supplied) To investigate acclimation mechanisms employed under extreme high light conditions, gene expression analysis was performed using the model microalgae Synechocystis sp. PCC 6803 (PCC 6803) cultured under various light intensities. From the low to the mid light conditions, the expression of genes related to light harvesting systems was repressed, whereas that of CO2 fixation and of D1 protein turnover-related genes was induced. more...

(Submitter supplied) The direct photosynthetic production of polyhydroxyalkanoate in cyanobacteria was improved by increasing carbon flux to biosynthetic pathway and introducing enzyme with higher activity. To understand the global transcriptional changes under photoautotrophic PHA biosynthesis conditions, RNA-seq analysis was performed.

(Submitter supplied) The unicellular cyanobacterium Synechocystis sp. PCC 6803 is a model system for studying biochemistry, genetics and molecular biology of photobiological processes. Despite its importance in basic and applied research, the genome-wide picture of transcriptional regulation in this bacterium is limited. Characteristic transcriptional responses to changes in the growth environment are expected to provide a scaffold for describing the Synechocystis transcriptional regulatory network as well as efficient means for functional annotation of genes in the genome. more...
