Degradation pathways: differentially expressed genes and patterns of expression across grain developmental time points (DAP). A) Carotenoid degradation pathways with the putative genes catalyzing each reaction. B) Genes expressed in a higher proportion at the beginning of grain development (14 DAP), C) Genes expressed in higher proportion at the end of grain development (42 DAP). Asterisks next to genes represent the genes that were differentially expressed across sorghum grain development time points. Positive Z-scores indicate higher expression compared to baseline
