Comparison of gene ontology (GO) results for our annotated full-length nontoxin sequences with those of the contigs from a de novo assembly with NGen. Only level 2 GO terms are shown. The distributions of GO terms are similar across data sets, suggesting that the annotated transcripts provided a comprehensive characterization of the genes expressed in the venom gland. (A) The distributions of sequences reaching various stages of identification and annotation are shown. The level 2 GO terms are shown for molecular function (B), biological process (C), and cellular component (D).
