Phenylpropanoid metabolism during growth and development of Capsicum frutescens fruits
Sukrasno, N. | Yeoman, M.M.
The production of capsaicinoids in fruits of Capsicum frutescens takes place after the increase in fruit length has ceased. However, before the onset of capsaicinoid synthesis, fruits actively accumulate p-coumaroyl, caffeoyl and 3,4-dimethoxycinnamoyl glycosides, 3-O-rhamnosylquercetin and 7-O-glucosylluteolin. The onset of capsaicinoid accumulation is paralleled by the disappearance of the three cinnamoyl glycosides and two flavonoids, together with the active accumulation of 'lignin-like' substances and the glycosides of vanillic acid, p-hydroxybenzaldehyde and several unknown C6-C1 compounds. These results are discussed in relation to the regulation of capsaicinoid synthesis.
