Abstract

The wax coating is an element of the lipid protective layer, the cuticle, which covers the above-ground organs of plants and is the main barrier that prevents non-stomatal water loss. The cuticle helps protect plant surfaces from pathogens and ultraviolet radiation and influences interactions between plants and insects. The accumulation of cuticular wax is one of the mechanisms of adaptation to drought stress. As a result, there are more and more reports on the relationship between cuticular wax and plant resistance to drought. This article deals with the relationship between cuticular waxes and drought resistance in cereals. The paper presents the achievements to date on (i) the relationship between wax biosynthesis and plant response to drought stress using glaucous and nonglaucous near-isogenic lines and on (ii) investigating the role of genes for cuticular wax biosynthesis and transport and the transcription factors that regulate them using mutants with disrupted wax coat formation.

叶片表皮蜡质作为谷物抗旱性的决定性状
蜡涂层是植物的脂质保护层(角质层)的一个组成部分,角质层覆盖着植物的地上器官,是防止非气孔水分流失的主要屏障。角质层有助于保护植物表面免受病原体和紫外线辐射的侵害,并影响植物和昆虫之间的相互作用。表皮蜡质积累是植物适应干旱胁迫的机制之一。因此,关于角质层蜡质与植物抗旱性之间关系的报道越来越多。本文研究了谷物表皮蜡质与抗旱性的关系。本文介绍了迄今为止在以下方面取得的成就:(1)利用白霜和非白霜近等基因系研究蜡生物合成与植物对干旱胁迫的反应之间的关系;(2)利用蜡被破坏的突变体研究表皮蜡生物合成和运输基因的作用以及调节这些基因的转录因子。
