malfunction | downregulation of RcEGS1 expression in flowers by virus-induced gene silencing leads to a reduction of the relative content of eugenol compared to wild-type flowers | Rosa chinensis |
physiological function | enzyme is responsible for eugenol biosynthesis in roses | Rosa chinensis |
physiological function | enzyme is responsible for eugenol biosynthesis in roses. Major volatile compounds from flower of Rosa x hybrida cv. Yunxiang at stage 4 are analyzed by SPME-GC/MS, the highest amount of 2-phenylethanol, followed by eugenol and methyleugenol, overview | Rosa hybrid cultivar |
