Proposed pathways for polysaccharide biosynthesis in P. cyrtonema. Activated monosaccharide units are marked in purple. Bold text in red background indicates key intermediates. Total expression levels of unigenes encoding enzymes involved in each step are shown. The columns L, R, and T represent leaf, root, and rhizome samples, respectively. Red and green represent high and low expression levels, respectively. Cluster of transcripts and Unigene are abbreviated as “CL” and “Un”, respectively. Arrows with solid lines represent the identified enzymatic reactions, and arrows with dashed lines represent multiple enzymatic reactions through multiple steps
