Genes that exhibited a 2-fold or greater alteration in expression in the PA2206C strain compared to the PA2206− mutant strain (p<0.05) are listed. Positive values indicate those genes which were upregulated in the PA2206C strain while values less than 1.0 indicate those genes which were downregulated.
