FIG 7.

Rank order expression of TA-associated genes from the whole S. meliloti genome (A) and the pSymA and pSymB megaplasmids of S. meliloti (B). RNA-seq read data were the mean data obtained using mRNA from S. meliloti P110 cells grown in media with limiting and excess phosphate. Those RNA-seq counts were combined with RNA-seq data extracted from Rm2011 cells as outlined by Sallet et al. (41). The expression was quantified as frequency of 5′ RNA-seq read counts per nucleotide within a given gene region, and the x axis represents the order of TA genes from the least to the most highly expressed. The expression data for each gene are in Table S3 in the supplemental material.
