ABSTRACT

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.

摘要

作为植物陆地化的适应性创新，角质层覆盖植物表面，极大地促进了陆地植物的发育和抗逆性。尽管在过去几十年中，由于角质层生物合成突变体和先进的角质层组成分析技术的贡献，在理解开花植物角质层生物合成的分子机制方面取得了巨大进展，但对角质层生物合成的起源和进化知之甚少。最近关于早期分化的现存陆地植物谱系苔藓植物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。在这篇小型评论中，我们强调了苔藓植物角质层生物合成的分子生物学的这些最新进展，
