Abstract: | When growth-phase cell suspension cultures of Capsicum annuum were treated with cellulase-elicitor preparation at 3 μg/ml, the level of capsidiol was transiently increased in the culture
media rather than in the cells reaching its maximum approx 24 h after treatment. With methyl jasmonate it took 18 h. Elicitor
treatment doubled phospholiphase A2 (PLA2) activity but simultaneous treatment with aristolochic acid, a PLA2 inhibitor, inhibited sesquiterpenoid accumulation as well as PLA2 activity. Mastoparan, a G protein activator, treatment also increased PLA2 activity and capsidiol production. Taken together, the present study shows that induction of capsidiol production in the
C. annuum is mediated by PLA2 activation. |
