Abstract
The production of capsaicin by cell suspension cultures
of Capsicum frutescens mediated through the calcium channel was studied. Administration of the calcium ionophore A23187 resulted in a 1.43-fold enhancement of the total capsaicin production in the cell suspension cultures. Treatments wherein the calcium channel modulators verapamil and chlorpromazine were administered resulted in lower growth and capsaicin production, suggesting that calcium is involved in the signal transduction of capsaicin pathway in the suspension culture. The activity of Ca2+ATPase, which
is a calmodulin-related enzyme, was also studied under
the influence of the calcium channel modulators.
Maximum activity of Ca2+ATPase was observed preceding
the capsaicin elicitation. The activity of capsaicin
synthase correlated with the increased capsaicin
levels under the influence of calcium ionophore.
