Distribution of genes with differentially altered expression into COGs. Effect of the tolC gene mutation on the S. meliloti transcriptome analyzed according to the distribution of the genes with altered expression into 20 functional categories (COGs) as predicted using NCBI database. The black and grey bars represent the percentage of genes in each functional category whose transcription was decreased and increased, respectively, in the tolC mutant SmLM030-2 by comparison to the wild-type strain 1021.
