摘要
水稻(Oryza sativa L.)作为全世界重要的粮食作物,提高其产量是保障国家粮食安全的重要策略。根系作为水稻最重要的器官之一,在水稻的生长发育、信号感知、激素合成、水分和养分吸收以及产量形成中起重要作用。然而,水稻根系的形成及生长发育也受到多种因素的影响。其中,植物激素在调控水稻根系生长发育过程中发挥着重要作用,使植物能够根据环境需求调节其发育、生长和生理状态。本文综述了影响水稻根系生长发育的非生物因素和生物因素;概述了与根系生长相关的基因及调控网络,重点阐述了植物激素在水稻根系形成及生长发育中的作用机制;总结了几种激素之间相互协同对根系的生长调控,并对其他影响根系的小分子物质进行讨论,旨在为水稻根系研究及提高水稻产量提供理论依据,也为今后更加精细化研究激素信号通路之间复杂的串扰以及和其他信号之间的作用机制提供新方向。
Being one of the major food sources in the world,rice(Oryza sativa L.)has been studied to promote its growth and increase its production for the security of human livelihood.Since the root system is crucial for the growth,signal perception,hormone synthesis,water and nutrient uptakes,and production of a rice plant,the formation,development,and functions of the system need to be well understood.However,since the affecting factors are numerous,the study could be challenging.For instance,plant hormones are of special interest regarding their roles in regulating root growth and development under everchanging environmental conditions.This article comprehensively reviewed subjects involving abiotic and biotic factors,related genes and regulatory networks,regulating plant hormones,and synergisms among hormones,metabolic trace minerals,and low-molecular substances.By emphasizing the studies on the plant hormones,it is hoped that research to further rice yield improvement and in-depth understanding of the basic biological mechanisms,complex interactions/interferences among biochemicals,and functional signaling pathways associated with rice root system development and functions will be realized.
