Abstract

SUMMARY: A heat-labile elicitor of phytoalexin accumulation in carrot ( L.) was detected in culture filtrate of grown in Czapek-Dox medium. The elicitor activity correlated with the activity of pectinolytic enzymes in the culture filtrates. The culture filtrates induced the release of heat-stable elicitors from carrot cell homogenates, pectic fraction of carrot cell walls and citrus pectin. The coincidence of heat sensitivity and sodium periodate inactivation profiles of elicitor and pectinolytic activity suggested that the activity of pectinolytic enzymes is essential for the release of the heat-stable elicitor. The culture filtrates of and showed similar elicitation patterns.
