Rapid Response of Suspension-cultured Parsley Cells to the Elicitor from Phytophthora megasperma var. sojae1: INDUCTION OF THE ENZYMES OF GENERAL PHENYLPROPANOID METABOLISM

RESUMO

Large and rapid increases in the activities of two enzymes of general phenylpropanoid metabolism, phenylalanine ammonia-lyase and 4-coumarate:CoA ligase, occurred in suspension-cultured parsley cells (Petroselinum hortense) treated with an elicitor preparation from Phytophthora megasperma var. sojae. Highest enzyme activities were obtained with an elicitor concentration similar to that required for maximal phenylalanine ammonialyase induction in cell suspension cultures of soybean, a natural host of the fungal pathogen.
