Comparison of sucrose-metabolic genes between sorghum genotypes. The expression dynamics of representative sucrose-metabolic genes were compared between sorghum genotypes and shown in heatmap (a), with the sucrose metabolism pathway shown in b. The cell colors are shaded to reflect the magnitude of log2 fold change of gene expression relative to the anthesis stages in each genotype. The expression levels in RPKM are labeled on each cell with statistical differences (q values determined by edgeR) indicated by asterisk (*q < 0.05; **q < 0.01; ***q < 0.005). The TPP gene highlighted in red was barely expressed in sweet lines Rio, Della and SIL05, but upregulated in BTx406 and R9188
