Fig. 2From: Comparative transcriptome analysis reveals sesquiterpenoid biosynthesis among 1-, 2- and 3-year old Atractylodes chinensisFunctional classification and pathway assignment of assembled unigenes by KEGG. The assembled unigenes were classified into six main categories in KEGG classification. The x-axis indicates the number of unigenes in category, and y-axis indicates the KEGG classificationBack to article page
