Coloration of sorghum leaves after infection with Bipolaris sorghicola . (A) Nakei-MS3B (right) has purple lesions and M36001 (left) has no change in color. Populations derived from Nakei-MS3B × M36001 had purple (#96), orange (#3, #127) or red (#62) lesions. (B) Quantification of accumulated pigments by LC-MS/MS. The “orange” lines (#3, #127) accumulated apigeninidin, whereas the “purple” lines (#96, Nakei-MS3B) accumulated luteolinidin. The “red” line (#62) accumulated both pigments. Box indicates color exhibited by lesions in each sorghum line.
