摘要:

植物表皮蜡质是植物与外界环境直接相接触的一层疏水保护层,由于它能够调节植物体内的水分应对干旱、盐和冷等非生物胁迫,因此对植物的生长和发育起着重要的作用。在不同的物种之间,植物表皮蜡质的结构和组成均有着很大差异,但都具有类似的蜡质合成途径,对该途径的研究已经取得了显著的成果。多种转录因子参与了植物的蜡质生物合成,其中隶属于AP2转录因子家族中的WIN/SHN通过与某些基因的启动子结合,调节蜡质合成相关基因的表达,从而影响蜡质的合成。在植物表皮蜡质合成的基础之上,重点对调节蜡质形成的转录因子WIN/SHN的结构特点、表达模式、转录调节作用及其对生理和表型的影响,以及对逆境的应答反应进行了综述,并对蜡质合成的复杂性问题进行了论述。鉴于蜡质对生命科学和农业生产实践的重要价值,深入开展包括WIN/SHN在内的遗传因子及环境因子对蜡质合成、调控与运转的机制研究将具有重要意义。

Abstract:

Plant cuticular wax is a hydrophobic protective layer by which plants directly contact with the external environment. Because it can regulate the water in plants to deal with abiotic stresses such as drought,salt and cold,it plays an important role in plant growth and development. Among different species,the structure and composition of the plant cuticular wax vary largely,but all have similar wax synthesis pathways,and remarkable research results on these pathways has achieved. Many transcription factors(TFs)are involved in the wax biosynthesis of plants. WIN/SHN,which belongs to the AP2 TF family,regulates the expressions of wax synthesis-related genes by binding to their promoters,thereby affecting the waxy synthesis. Based on the synthesis of plant cuticular wax,this article focuses on the review of WIN/SHN TFs,including their structural characteristics,expression patterns,transcriptional regulation and the effects on physiology and phenotype,as well as their responses to stresses. Furthermore,the complexity of wax synthesis is also discussed. In view of the important value of wax for life science and agricultural production practice,it is of great significance to carry out in-depth research on the mechanism of wax synthesis,regulation,transport and deposition regulated by the genetic and environmental factors including WIN/SHN TFs.
