Functional distribution of the specific genes. a Proportions of each COG categories in the bacteria from different habitats. b The repartition of the four functional categories in each studied habitat. The red stars indicate the overrepresented functions in a habitat, compared to the other habitats, we also indicated the percent of specific genes supporting these functions
