Genetic network of putative positively selected genes (PSGs) and their functions. Functions are defined using GO and KEGG annotations and network is constructed using the Rgraphviz package. Each solid circle or square represents a gene or a functional category. PSGs between the two species are very similar in functions and pathways. They were mostly concentrated in functions related to metabolism, especially nutrient metabolism, and defense response
