Biosynthesis pathway: differentially expressed genes and patterns of expression across grain developmental time points (DAP). A) Carotenoid biosynthesis pathway 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 times. Positive Z-scores indicate higher expression compared to baseline
