Elicitor and calatalse activity of conidia suspensions of various strains of Magnaporthe grisea in suspension-cultured cells of rice.
A conidia suspension of Magnaporthe grisea carried elicitor activity that induced the expression of defense-related genes and the production of H(2)O(2) in suspension-cultured rice cells. The levels of H(2)O(2) produced were dependent on fungal isolates and were correlated with the catalase activity in the supernatant fraction of each conidia suspension, not with gene-for-gene interactions.
