Functional annotation of unigenes. (A) GO ontology annotation of the A. roxburghii (JXL28) transcriptome showing the major GO terms in the molecular function, biological process, and cellular component categories. (B) Histogram representation of the cluster of orthologous group (COG) classification for assembled unigenes. (C) A KEGG analysis of the JXL28 transcriptome showing the top 20 highly represented KEGG pathways. The X-axis indicates the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways, and the Y-axis indicates the number of transcripts in each pathway. (D) Species-based distribution of blastx matches for each clustered unitranscript of the JXL28 transcriptome. The species with a match < 1% are grouped in the “Other” category.
