General Information

General Information Comment Organism
physiological function feeding of leaves with geraniol, but not tryptophan (precursor fortryptamine), increases the accumulation of the monoterpene indole alkaloids catharanthine and vindoline. Gene silencing significantly reduces the monoterpene indole alkaloid content. Overexpression of GES in leaves increased monoterpene indole alkaloids content. GES exhibits correlation with monoterpene indole alkaloids levels in leaves of different Cataranthus roseus cultivars and has significantly lower expression relative to other pathway genes Catharanthus roseus
