摘要
在开花植物中,性别表达是区分雄花和雌花的重要过程.激素可影响植物性别的转变或可塑性,大量的植物激素涉及花性别鉴定基因和发育通路,对植物发育过程中花性别分化具有重要意义.主要综述五种植物激素(如生长素、赤霉素、细胞分裂素、乙烯、脱落酸等)在植物性别分化中的作用.外源生长调节物质还可以通过调节有关酶的活性和内源激素的水平来影响植物性别分化.赤霉素可促进部分植物的雄性表达,生长素、脱落酸、乙烯及细胞分裂素可促进部分植物的雌性表达.为揭示激素对性别分化的影响的分子调控机制奠定了基础.
Abstract
In flowering plants,sex expression is an important process for distinguishing between male and female flowers.Hormone can affect the change of plant sex or plasticity,a large number of plant hormones involves flower sex identification genes and developmental pathway,in the process of plant development flower sex differentiation is of great significance.Mainly review five kinds of plant hormones(such as auxin,gibberellin,cytokinin,ethylene,abscisic acid,etc)in the role of plant sex differentiation.Exogenous growth regulators can also influence plant sex differentiation by modulating the activity of related enzymes and the levels of endogenous hormones.Gibbberellin can promote the male expression of some plants,while auxin,abscisic acid,ethylene and cytokinin can promote the female expression of some plants.Lays the foundation for revealing the molecular regulatory mechanisms of the effects of hormones on sex differentiation.
