Fig. 1From: Patterns of abundance, chromosomal localization, and domain organization among c-di-GMP-metabolizing genes revealed by comparative genomics of five alphaproteobacterial ordersNumbers of sequences with GGDEF, EAL or HD-GYP sequences in the five orders. The number of genomes and the total number of sequences for each order are above the diagrams. The Venn diagrams show the numbers of sequences with both GGDEF and EAL domains in the corresponding overlapping circles. The coloration is a gradient from the highest (red) to lowest (white) values within each orderBack to article page
