A Wheat Cell Wall Fragment Suppresses Elicitor-induced Resistance Responses and Disturbs Fungal Development

A fraction prepared by Pectolyase-digestion of wheat cell walls suppressed plant responses when co-injected with a fungal elicitor of hypersensitive-like lignification.This fraction also reduced haustorial mother cell formation and prevented the development of haustoria when injected into wheat leav...

Zusammenfassung:	A fraction prepared by Pectolyase-digestion of wheat cell walls suppressed plant responses when co-injected with a fungal elicitor of hypersensitive-like lignification.This fraction also reduced haustorial mother cell formation and prevented the development of haustoria when injected into wheat leaves prior to inoculation with the stem rust fungus.
