3.3 Functional annotation of unigenes
All 84,627 SMRT sequencing from these unigenes were functionally annotated by searching seven databases: NR, Swiss-Prot, KEGG, KOG, eggNOG, GO, and Pfam. A total of 62,612 (73.99%) unigenes were annotated in at least one database. The most, 57,846 (68.35%) unigenes, were functionally annotated in the NR database. The least, 5,192 (6.14 %) unigenes, were functionally annotated in the KEGG database (Figure 2B). The functional annotations of all 84,627 unigenes are listed in Table S1.
