Plant cuticular wax, the last barrier of self-defense, plays an important role in plant growth and development.
2
However, the molecular and evolutionary mechanisms of cuticular wax in plants in response to drought stress are still lacking.
3
In this review, we focus on potential mechanisms, from evolutionary, molecular, and physiological aspects, that control cuticular wax and its roles in plant drought tolerance.
4
We propose that OsGL1-6 is involved in the accumulation of leaf cuticular wax and directly impacts drought resistance in rice.
5
Cuticular wax is a class of organic compounds that comprises the outermost layer of plant surfaces.
6
The comparative analysis of cuticular waxes revealed an increased accumulation of alkanes in leaves of transgenic lines.
7
Cuticular wax, the first protective layer of above ground tissues of many plant species, is a key evolutionary innovation in plants.
