Universal genes were grouped according to their Clusters of Orthologous Groups of proteins (COG) functional categories. Information storage and processing includes COG categories J, A, K, L, and B; cellular processes and signaling includes COG categories D, Y, V, T, M, N, Z, W, U, and O; Metabolism includes C, G, E, F, H, I, P, and Q; Poorly characterized includes R and S. Because some genes have been annotated into multiple COG categories, the sum of individual groups is slightly larger than the total number of single-copy genes.
After Bonferroni correction for multiple tests at the 0.05 level.
Significance was determined when P < 0.05 was observed in all three tests (NSS, Max χ2, and Phi) in the Phi package.
