GO annotation (A) and COG classification (B) of the 3,343 unigenes that were highly expressed in the trichomes and that were also present both Hubei- and Zunyi-cultivars. In the “biological process” category of the GO annotation, most unigenes were assigned to the term “metabolic process” (1,329 unigenes; 40%). With a COG classification, a number of unigenes were assigned to metabolism-related processes, including 145 unigenes for the “carbohydrate transport and metabolism,” 146 for the “lipid transport and metabolism,” and 120 for the “secondary metabolites biosynthesis, transport and catabolism.”
