Abstract
High molecular weight cell wall components from Phytophthora infestans caused "browning" in tomato callus, a decrease in survival of single tomato cells, and elicited antimicrobial compounds synthesis. Treated callus extracts inhibited germination of conidia, and reduced germ tube length and mycelial growth. Results were discussed for new knowledges in P. infestans-Tomato system and further possibilities for more thorough investigations on the kinetics and mechanisms of phytoalexin induction in plant tissue culture.
