Genomic deletion at the F3′H locus. (A) Genomic structure of F3′H loci. Three F3′H genes are tandemly duplicated in BTx623. Nakei-MS3B has a genomic deletion affecting Sb04g024710 and Sb04g024730, resulting in fusion of the open reading frames of these F3′H genes (Sb04g024710N). (B, C) Genomic PCR analysis. Genomic PCR of F2 lines derived from Nakei-MS3B × M36001 (B) and five sorghum varieties (C). Boxes at bottom indicate colors on areas of each sorghum plant infected with Bipolaris sorghicola. Positions of the PCR primers are indicated by arrowheads in panel A.
