Plants live in constantly changing environments that are often unfavorable or stressful. Root development strongly affects plant growth and productivity, and the developmental plasticity of roots helps plants to survive under abiotic stress conditions. This review summarizes the progress being made in understanding the regulation of the phtyohormone ethylene in rice root development in response to abiotic stresses, highlighting the complexity associated with the integration of ethylene synthesis and signaling in root development under adverse environments. Understanding the molecular mechanisms of ethylene in regulating root architecture and response to environmental signals can contribute to the genetic improvement of crop root systems, enhancing their adaptation to stressful environmental conditions.
植物生长于不断变化的环境中，这些环境常常不利或具有胁迫性。根系发育强烈影响植物的生长和生产力，而根系的发育可塑性有助于植物在非生物胁迫条件下存活。本综述总结了在理解植物激素乙烯对水稻根系发育响应非生物胁迫的调控方面所取得的进展，强调了在不利环境下根系发育中乙烯合成与信号整合的复杂性。了解乙烯调控根系结构及对环境信号响应的分子机制，有助于作物根系系统的遗传改良，增强其对胁迫环境条件的适应性。
