Plot of log₂ expression ratios of selected genes from transcriptomic data against proteomic data. In cases where no peptides were detected in the proteome in all three biological replicates, a value of 1 is assigned as the pseudo-spectrum count to avoid infinity and allow a ratio to be calculated. ■ represents genes that were differentially regulated in the proteome and in the transcriptome by 2-fold or greater, ♦ represents genes that were differentially regulated in the proteome and in the transcriptome but by less than 2-fold, ▲ represents genes that were differentially regulated by 2-fold or greater in the transcriptome but were not differentially regulated in the proteome, and × represents genes that were differentially regulated by less than 2-fold in the transcriptome and were not differentially regulated in the proteome. Genes that are related to nitrogen fixation are labeled with their locus tags.
