Comparison of starch-metabolic genes between sorghum genotypes. The expression dynamics of representative starch-metabolic genes were compared between sorghum genotypes and shown in heatmap (a), with the starch-metabolic 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 geneIDs highlighted in red are those shared the upregulation expression trends between sweet lines Rio, Della and SIL05 but contrast to BTx406 and R9188
