RNA-seq of Pseudomonas aeruginosa PAO1 planktonic and biofilm cells treated with coumarin

Coumarin has been reported as a quorum sensing inhibitor for Pseudomonas aeruginosa. The goal of this transcriptomic analysis is to elucidate the effect of coumarin on gene expression of P. aeruginosa. Therefore, planktonic cells of P. aeruginosa were treated by coumarin for 1h and biofilms were formed in the presence of coumarin for 24h. Unreated controls (with dimethyl sulfoxide ) for both planktonic and biofilm samples were also included. Three biological replicates per treatment were performed with RNA sequencing.
