| metabolism | prephenate dehydratase takes part in the biosynthetic pathway of flavan-3-ols, overview | Camellia sinensis |
| additional information | a decrease in catechins content, 2-phenylethanol, and PDT activity is observed in the tea shoots infested by Exobasidium vexans over healthy shoots. Drought stress induced by withholding water for a period of 8 days causes initial increase in the contents of the catechins and 2-phenylethanol, and in PDT activity, but decreases with 3 day onwards with an increase in the severity of water stress, detailed overview | Camellia sinensis |
