Deep sequencing-based identification of small regulatory RNAs in Synechocystis sp. PCC 6803.

ABSTRACT: Synechocystis sp. PCC 6803 is a genetically tractable model organism for photosynthesis research. The genome of Synechocystis sp. PCC 6803 consists of a circular chromosome and seven plasmids. The importance of small regulatory RNAs (sRNAs) as mediators of a number of cellular processes in bacteria has begun to be recognized. However, little is known regarding sRNAs in Synechocystis sp. PCC 6803. To provide a comprehensive overview of sRNAs in this model organism, the sRNAs of Synechocystis sp. PCC 6803 were analyzed using deep sequencing, and 7,951,189 reads were obtained. High quality mapping reads (6,127,890) were mapped onto the genome and assembled into 16,192 transcribed regions (clusters) based on read overlap. A total number of 5211 putative sRNAs were revealed from the genome and
