Color variation in sorghum is controlled by the expression level of the F3'H gene

ABSTRACT: Sorghum populations derived from Nakei-MS3B and M36001 accumulated apigeninidin, or both apigeninidin and luteolinidin, in different proportions in lesions caused by B. sorghicola infection, suggesting that the relative proportions of the two 3-deoxyanthocyanidins determine color variation. QTL analysis and genomic sequencing indicated that two closely linked loci on chromosome 4, containing the flavonoid 3′-hydroxylase (F3′H) and Tannin1 (Tan1) genes, were responsible for the lesion color variation. The F3′H locus in Nakei-MS3B had a genomic deletion resulting in the fusion of two tandemly arrayed F3′H genes. The recessive allele at the Tan1 locus derived from M36001 had a genomic insertion and encoded a non-functional WD40 repeat transcription factor. Whole-mRNA sequencing reveal
