Abstract

A conidia suspension of Magnaporthe grisea carried elicitor activity that induced the expression of defense-related genes and the production of H₂O₂ in suspension-cultured rice cells. The levels of H₂O₂ 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.
