Figure 2From: cTFbase: a database for comparative genomics of transcription factors in cyanobacteriaRelationship between the number of TFs and the total number of ORFs in 21 cyanobacterial genomes. The total number of ORFs in each genome was plotted as a function against the number of TFs. Triangle indicates marine cyanobacteria, while square indicates fresh or soil cyanobacteria.Back to article page
