Functional annotations of Paradoxornis webbianus bulomachus contigs. A: Distribution of the assigned number of gene ontology (GO) terms per contig. The mean level of assigned GO terms was 6.0 ± 1.8 for a total of 60,008 annotated terms. B: Distribution of GO assignment (second-level GO terms) in the three main GO categories (cellular component, molecular function and biological process). Counts of terms of < 100 were combined in the figure. ‘Other’ within ‘molecular function’ combines 5 terms including electron carrier (75 counts), antioxidant (31 counts), translation regulator (13 counts), nutrient reservoir (2 counts) activities and protein tag (1 count).
