Schematic representation of the sucrose, cellulose and starch metabolic pathways, showing genes identified with supporting RNA-seq mapping information. The grey boxes represent enzyme products. The arrows represent enzyme reactions, solid arrows are enzyme reactions where the predicted enzyme-coding genes were identified in sugarcane, dotted arrows where the gene was not identified. EC numbers are shown for the predicted enzyme-coding genes identified. EC numbers in red indicate predicted enzyme-coding genes that were mapped with more than a thousand RNA-seq reads. The number of mRNA reads mapped is indicated in parentheses below the EC number. If more than one BAC to a single Sorghum loci was sequenced, the minimum and the maximum number of reads mapped to all BACs are shown. EC 126.96.36.199: beta-fructofuranosidase, 188.8.131.52: sucrose-6-phosphate phosphohydrolase, EC 184.108.40.206: sucrose phosphate synthase, EC 220.127.116.11: cellulose synthase, EC 18.104.22.168: sucrose synthase, EC 22.214.171.124: UDP glucose pyrophosphorylase, EC 126.96.36.199: xylan 1,4-beta-xylosidase, EC 188.8.131.52: pectinesterase, EC 184.108.40.206: polygalacturonase, EC 220.127.116.11: phosphoglucomutase, EC 18.104.22.168: glucose-1-phosphate adenylyltransferase, EC 22.214.171.124: starch synthase, EC 126.96.36.199: 1,4-alpha-glucan branching enzyme and EC 188.8.131.52: beta-amylase.
