Induced accumulation of cuticular waxes enhances drought tolerance in Arabidopsis by changes in development of stomata

► Conditional expression of the WIN1/SHN1 gene in transgenic Arabidopsis. ► Induction of WIN1/SHN1 gene expression results in increased epicuticular wax. ► Induced wax accumulation reduces the development of stomata. ► Induced accumulation of wax increases drought tolerance.
