As an adaptive innovation in plant terrestrialization, cuticle covers the plant surface and greatly contributes to the development and stress tolerance in land plants. Although past decades have seen great progress in understanding the molecular mechanism of cuticle biosynthesis in flowering plants with the contribution of cuticle biosynthesis mutants and advanced cuticle composition profiling techniques, origins and evolution of cuticle biosynthesis are poorly understood. Recent chemical, phylogenomic, and molecular genetic studies on cuticle biosynthesis in early-diverging extant land plant lineages, the bryophytes, shed novel light on the origins and evolution of plant cuticle biosynthesis. In this mini-review, we highlighted these recent advances in the molecular biology of cuticle biosynthesis in bryophytes, and provided evolutionary insights into plant cuticle biosynthesis.
作为植物陆地化的一种适应性创新，角质层覆盖在植物表面，对陆生植物的发育和胁迫耐受有很大贡献。尽管过去几十年在理解有花植物角质层生物合成的分子机制方面取得了很大进展，角质层生物合成突变体和先进的角质层成分分析技术做出了贡献，但角质层生物合成的起源和进化仍知之甚少。最近对早期分化的现存陆地植物类群——苔藓植物的角质层生物合成的化学、系统基因组学和分子遗传学研究，为植物角质层生物合成的起源和进化提供了新的线索。在这篇综述中，我们强调了苔藓植物角质层生物合成分子生物学方面的这些最新进展，并为植物角质层生物合成提供了进化见解。
