The Small RNA ncS35 Regulates Growth in Burkholderia cenocepacia J2315.

ABSTRACT: Burkholderia cenocepacia J2315 is a member of the B. cepacia complex. It has a large genome with three replicons and one plasmid; 7,261 genes code for annotated proteins, while 113 code for functional RNAs. Small regulatory RNAs of B. cenocepacia have not yet been functionally characterized. We investigated a small regulatory RNA, designated ncS35, that was discovered by differential RNA sequencing. Its expression under various conditions was quantified, and a deletion mutant, ΔncS35, was constructed. Compared to planktonic growth in a rich medium, the expression of ncS35 was elevated when B. cenocepacia J2315 was grown in biofilms and in minimal medium. Cells of the deletion mutant showed increased aggregation, higher metabolic activity, a higher growth rate, a
