Epicuticular waxes serve as a protective layer on plant aerial surfaces. The chemical reactions of wax biosynthesis are well understood, but little is known about the underlying regulatory mechanisms. New data from Yang et al. and Lange et al. argue that RNA degradation and silencing play a key role in regulating the content of alkanes, the most abundant components of wax.
表皮蜡质在植物气生表面起保护作用。蜡质生物合成的化学反应已被充分了解，但对其潜在的调控机制知之甚少。Yang 等人和 Lange等人的新数据表明，RNA 降解和沉默在调节烷烃（蜡质中最丰富的成分）含量方面发挥着关键作用。
