Study on the function of <i>TTG1</i> gene in <i>Camellia oleifera</i>.

ABSTRACT: Camellia oleifera is an economically important woody oil crop in China, where seed oil quality and yield are critical determinants of commercial value. Although the WD40-repeat transcription factor TTG1 is known to regulate plant secondary metabolism and development, its specific functions in C. oleifera remain uncharacterized. In this study, we isolated the CoTTG1 gene from C. oleifera, which encodes a nuclear-localized protein (molecular weight 38.38 kDa, pI 5.0) sharing 99.71% sequence identity with Camellia japonica TTG1. Heterologous expression resulted in: (1) significantly increased leaf trichome density (up to 114 trichomes/50 mm²); (2) enhanced seed anthocyanin accumulation (199-318% increase); and (3) substantial alterations in fatty acid
