Gene Ontology (GO) classification of novel expression-validated genes (EVGs). EVGs not supported by the expressed sequence data (2,093) were submitted to a search against the Pfam database. Those with significant alignments (339) were assigned GO codes based on Pfam. The pie charts show the distribution of GO terms within this set of EVGs. Note that the total number of GO terms in each category is greater than the number of EVGs because of assignment of multiple GO terms to some EVGs. (a) Distribution of the different 'biological process' GO codes assigned to the EVGs with significant hits to the Pfam database: a total of 526 GO terms. (b) Distribution of the different 'molecular function' GO codes assigned to the EVGs with significant hits to the Pfam database: a total of 374 GO terms.
