J. Malarz et W. Kisiel, Effect of pectinase on the production of sesquiterpene lactones in the hairy root culture of Lactuca virosa L., ACT SOC BOT, 69(2), 2000, pp. 115-117
Direct addition of pectinase as an elicitor to the hairy root culture of La
ctuca virosa L. transformed with Agrobacterium rhizogenes stimulates the ac
cumulation of constitutive sesquiterpene lactones - lactuside A and crepidi
aside B. The highest amounts of lactuside A (80% above the control level) a
nd crepidiaside B (39% above the control level) have been found 24 and 48 h
ours, respectively, after pectinase treatment.
