Host-Pathogen InteractionsXII. Response of Suspension-cultured Soybean Cells to the Elicitor Isolated from Phytophthora megasperma var. sojae, a Fungal Pathogen of Soybeans

Host-Pathogen InteractionsXII. Response of Suspension-cultured Soybean Cells to the Elicitor... Abstract The glucan elicitor isolated from the mycelial walls of Phytophthora megasperma var. sojae, the fungus which causes stem and root rot in soybeans, stimulates the activity of phenylalanine ammonia-lyase and the accumulation of glyceollin in suspension-cultured soybean cells.

Glyceollin is a phenylpropanoid-derived phytoalexin which is toxic to P. megasperma var. sojae.
