Functional classification of the assembled unigenes. (A) Functional classification of the assembled unigenes based on Gene Ontology (GO) categorisation. The results are summarised in three main GO categories: biological processes, cellular components and molecular functions. The x-axis indicates the subcategories, and the y-axis indicates the numbers related to the total number of GO terms present; the unigene numbers that are assigned the same GO terms are indicated at the top of the bars. (B) Histogram of Clusters of Orthologous Groups (COG) classification. The unigenes were aligned to the COG database to predict and classify possible functions. Out of 25,619 hits in the NCBI non-redundant (nr) database, 10,806 unigenes were annotated and separated into 25 clusters.
