Functional enrichment of unigenes from Litopenaeus vannamei. (A) KOG classification of unigenes. Each bar represents the number of unigenes classified into each of the 26 KOG functional categories. (B) Gene Ontology (GO) classification of unigenes. Three major GO categories were enriched: biological process, cellular component, and molecular function. (C) Kyoto Encyclopedia of Genes and Genomes (KEGG) classification of unigenes. The unigenes were assigned to six special KEGG pathways, including organismal systems, metabolism, human diseases, genetic information processing, environmental information processing, and cellular processes.
