A total of 5,192 unigene sequences were annotated by the KEGG data and plotted to 87 operative catalogs. Genetic information processing was the largest transcript category including translation, transcription, folding, sorting, and degradation (Figure 4). The first four transcript-related pathways in the genetic information processing were spliceosome (505, 9.7%), ribosome (471, 9.1%), protein processing in endoplasmic reticulum (435, 8.4%), and RNA transport (4335, 8.3%) (Table S2). Gene function was classified by KOG data and most were defined specifically in signal transduction mechanisms, posttranslational modification, protein turnover, chaperones, cytoskeleton, intracellular trafficking, secretion, and vesicular transport (Figure S2). A large number of KOG-annotated genes were related to neuron cell commitment and sensation, such as neuropeptide signal transduction (122), innervation activity (50), sensory perception of sound (357), sensory perception of light stimulus (22), and neurotransmitter biosynthesis including gamma-aminobutyric acid (144), dopamine secretion (77), G protein-coupled serotonin receptor (10), and histamine secretion (7) (Table S1).
