title: Putrescine facilitated enhancement of capsaicin production in cell suspension cultures of Capsicum frutescens.
abstract: Putrescine treatment (0.1 mmol/L) influenced enhancement of growth and capsaicin production in the cell suspension cultures of C. frutescens. The administration of polyamine inhibitor DFMA (alpha-DL-difluoromethylarginine) resulted in a reduction of the growth, capsaicin content and the endogenous titres of polyamines (PAs). The capsaicin synthase activity was also higher in the putrescine (Put) treated cultures. Ethylene levels were lower in the cultures treated with putrescine. This study suggested that Put facilitates growth and capsaicin production.
