Fig. 1From: Unraveling transcriptomics of sorghum grain carotenoids: a step forward for biofortificationSamples hierarchical clustering and heat map of total carotenoid concentration at maturity for each accession. Darker colors in the heat map represent higher carotenoid concentrations, which were measured at maturity in a previous study [56]. R1-R3 denotes each biological replicateBack to article page
