Plant cuticle is the hydrophobic protection layer that covers aerial plant organs and plays a pivotal role during plant development and interactions of plants with the environment. The mechanical structure and chemical composition of cuticle lipids and other secondary metabolites vary considerably between plant species, and in response to environmental stimuli and stresses. As the cuticle plays an important role in responses of plants to major abiotic stresses such as drought and high salinity, close attention has been paid to molecular processes underlying the stress-induced biosynthesis of cuticle components. This review addresses the genetic networks responsible for cuticle formation and in particular highlights the role of transcription factors that regulate cuticle formation in response to abiotic stresses.
植物表皮是覆盖在气生植物器官表面的疏水保护层,在植物发育和与环境相互作用过程中起着关键作用。表皮脂质和其他次生代谢物的机械结构和化学成分在不同植物物种之间差异很大,并对环境刺激和胁迫做出响应。由于表皮在植物对主要非生物胁迫(如干旱和高盐)的响应中起着重要作用,因此人们密切关注表皮成分胁迫诱导合成的分子过程。本文综述了负责表皮形成的遗传网络,特别强调了转录因子在响应非生物胁迫调节表皮形成中的作用。
