Flavonoid components and flower color change in transgenic tobacco plants by suppression of chalcone isomerase gene.

FEBS letters - 7 Nov 2005

Nishihara Masahiro, Nakatsuka Takashi, Yamamura Saburo

Abstract excerpt

A cDNA encoding chalcone isomerase (CHI) was isolated from the petals of Nicotiana tabacum and the effect of its suppression on flavonoid biosynthesis was analyzed in transgenic tobacco plants. CHI-suppression by RNA interference (RNAi) showed reduced pigmentation and change of flavonoid components in flower petals. The plants also accumulated high levels of chalcone in pollen, showing a yellow coloration. Our...
