Plants often live in adverse environmental conditions and are exposed to various stresses, such as heat, cold, heavy metals, salt, radiation, poor lighting, nutrient deficiency, drought, or flooding. To adapt to unfavorable environments, plants have evolved specialized molecular mechanisms that serve to balance the trade-off between abiotic stress responses and growth. These mechanisms enable plants to continue to develop and reproduce even under adverse conditions. Ethylene, as a key growth regulator, is leveraged by plants to mitigate the negative effects of some of these stresses on plant development and growth. By cooperating with other hormones, such as jasmonic acid (JA), abscisic acid (ABA), brassinosteroids (BR), auxin, gibberellic acid (GA), salicylic acid (SA), and cytokinin (CK), ethylene triggers defense and survival mechanisms thereby coordinating plant growth and development in response to abiotic stresses. This review describes the crosstalk between ethylene and other plant hormones in tipping the balance between plant growth and abiotic stress responses.
植物常常生活在不利的环境条件下，面临各种胁迫，如高温、低温、重金属、盐分、辐射、光照不足、养分缺乏、干旱或洪涝。为了适应不利环境，植物进化出了专门的分子机制，以平衡非生物胁迫响应与生长之间的权衡。这些机制使植物即使在不利条件下也能继续生长和繁殖。乙烯作为一种关键的生长调节剂，被植物用来减轻其中一些胁迫对植物发育和生长的负面影响。通过与茉莉酸（JA）、脱落酸（ABA）、油菜素内酯（BR）、生长素、赤霉素（GA）、水杨酸（SA）和细胞分裂素（CK）等其他激素协同作用，乙烯触发防御和生存机制，从而协调植物在非生物胁迫下的生长和发育。本综述描述了乙烯与其他植物激素之间的相互作用，这种相互作用影响着植物生长与非生物胁迫响应之间的平衡。
