【摘要】：植物分枝角度是形成理想株型的最重要组成部分,其与植物的产量形成、适应环境能力和竞争能力密切相关。植物分枝角度受遗传因素、植物激素和环境因素等多重调控,但是遗传因素起主要作用。近年来的研究表明:TILLER ANGLE CONTROL1(TAC1)、LAZY1(LA1)、PROSTRATE GROWTH1(PROG1)、LOOSE PLANT ARCHITECTURE1(LPA1)等基因在调节植物分枝角度中起关键作用;植物激素,如生长素和独角金内酯等,对分枝角度的调控也起到关键作用。此外,环境与基因、激素之间的交互作用同样可调节分枝角度。而不同基因调控分枝角度的机制不同,基因可通过与蛋白质、酶、激素或者与其它基因的交互作用调节分枝角度。本研究主要介绍了这些基因在调控植物分枝角度中的相关分子机制,为深入了解植物分枝角度的调控机制提供参考。
[Abstract]:Plant branching angle is the most important component of forming ideal plant type, which is closely related to plant yield formation, adaptability to environment and competitiveness. Branching angle is regulated by genetic factors, plant hormones and environmental factors, but genetic factors play a major role. Recent studies have shown that: TILLER ANGLE CONTROL1 (TAC1), LAZY1 (PROG1), LOOSE PLANT ARCHITECTURE1 (LPA1) and other genes play a key role in regulating the branching angle of plants. Plant hormones, such as auxin and monogalactone, also play a key role in the regulation of branching angles. In addition, the interaction between environment and genes, hormones can also adjust the branching angle. Different genes regulate branching angle through interaction with proteins, enzymes, hormones or other genes. In this study, the molecular mechanism of these genes in the regulation of branching angle of plants is introduced, which provides a reference for further understanding the regulation mechanism of branching angle of plants.
