Sorghum produces phytoalexins that are 3-deoxyanthocyanidin flavonoids. The compounds inhibit the growth of phytopathogenic fungi in vitro. The phytoalexins appear to be synthesized in subcellular inclusions within a host epidermal cell that is about to be penetrated by a fungus. This site-restricted synthesis suggests that the phytoalexin response occurs initially in the first cells that come under fungal attack and is not simply a response of cells that surround the original infection site.

Knowledge to Exploit for Improved Management Anthracnose, caused by the fungus Colletotrichum graminicola (Ces.) G.W. Wils., is a disease of worldwide importance on corn (Zea mays) (33,95,98). The disease affects all parts of the plant and can be found at any time during the growing season, but it is observed most frequently in the form of anthracnose leaf blight (ALB) or anthracnose stalk rot (ASR) (Fig. 1).
