Abstract

Sorghum seedlings were inoculated with Fusarium proliferatum and F thapsinum 3 days after germination Seven days later infected seedlings were dissected into the coleoptile mesocotyl seed scutellum and root and defence responses measured Infection significantly increased the levels of soluble phenolics and anthocyanins the phytoalexins apigeninidin and luteolinidin and the enzymes peroxidase beta;13glucanase and chitinase in some tissues Constitutive levels of chitinase were high The strongest defence responses and highest levels of preformed defences were seen in the scutellum Responses to F thapsinum tended to be stronger than those to F proliferatum The findings supported the hypothesis that the plant is able to suppress the activity of these fungi during the endophytic stage of infection
