水分胁迫对植物基因表达的影响(英文)

Effect of Water-Deficit Stress on Plant Gene Expression

水分胁迫会引起植物基因表达发生变化,这些变化可能导致植物从细胞水平上进行调节,并适应这种水分胁迫的环境.虽然前人从细胞水平上对水分胁迫的反映进行了大量的研究,但随着研究的不断深入,人们发现从分子水平上弄清楚植物对胁迫的反应显得更为重要.就植物细胞对水分胁迫感知、基因表达调控及ABA的合成与调控方面进行了综述.

Many changes in gene expression occur in response to water-deficit stress. These changes may lead to cellular adaptation of water-deficit stress. A challenge is to determine which changes support plant adaptation to conditions of reduced soil water content and which occur in response to lesions in metabolic and cellular functions. Most work in this field has concentrated on the responses to water-deficit stress at the cellular level, but as people＇s understanding improves, it will be important to develop a framework to integrate the cellular responses with whole plant responses. Therefore, this paper reviewed the whole reaction of plant to the water-deficit stress on sensing cellular water deficit, genes regulated by the water-deficit stress and regulation of ABA synthesis.
