Genotypes normalized transcript counts for carotenoid biosynthesis genes differentially expressed at 42 DAP in high versus low carotenoid sorghum accessions. A) Phytoene Synthase (PSY); B) Phytoene desaturase (PDS). PI329435 and PI510924 represent the low carotenoid group, while PI585347 and PI585348 represent the high carotenoid group. Differences in gene expressions were assessed at the group level (High vs. Low), not at the genotype level
