RNA-seq of P. aeruginosa clinical isolate collection under biofilm growth conditions
Purpose : The goal of this study was to use RNA-seq to compare transcriptional profiles under biofilm conditions with planktonic growth and explore the correlation of gene expression of a collection of clinical P. aeruginosa isolates to various phenotypes, such as biofilm structure or virulence. Methods : mRNA profiles were generated for Pseudomonas aeruginosa clinical samples derived from various geographical locations by deep sequencing. The removal of ribosomal RNA was performed using the Ribo-Zero Bacteria Kit (Illumina) and cDNA libraries were generated with the ScriptSeq v2 Kit (Illumina). The samples were sequenced in single end mode on an Illumina HiSeq 2500 device or paired end mode on an Illumina Novaseq 6000. mRNA reads were trimmed and mapped to the NC_008463.1 (PA14) reference genome from NCBI using bowtie2 with default settings. Overall design: mRNA profiles from Pseudomonas aeruginosa derived from static biofilm cultures grown for 12h to 48h in 96-well microtiter plates or planktonic LB cultures grown to an OD600 = 2 and deep sequenced using Illumina HiSeq 2500/NovaSeq 6000.
