More than a half-century has passed since it was discovered that phytohormone cytokinin (CK) is essential to drive cytokinesis and proliferation in plant tissue culture. Thereafter, cytokinin has emerged as the primary regulator of the plant cell cycle and numerous developmental processes. Lately, a growing body of evidence suggests that cytokinin has a role in mitigating both abiotic and biotic stress. Cytokinin is essential to defend plants against excessive light exposure and a unique kind of abiotic stress generated by an altered photoperiod. Secondly, cytokinin also exhibits multi-stress resilience under changing environments. Furthermore, cytokinin homeostasis is also affected by several forms of stress. Therefore, the diverse roles of cytokinin in reaction to stress, as well as its interactions with other hormones, are discussed in detail. When it comes to agriculture, understanding the functioning processes of cytokinins under changing environmental conditions can assist in utilizing the phytohormone, to increase productivity. Through this review, we briefly describe the biological role of cytokinin in enhancing the performance of plants growth under abiotic challenges as well as the probable mechanisms underpinning cytokinin-induced stress tolerance. In addition, the article lays forth a strategy for using biotechnological tools to modify genes in the cytokinin pathway to engineer abiotic stress tolerance in plants. The information presented here will assist in better understanding the function of cytokinin in plants and their effective investigation in the cropping system.
自发现植物激素细胞分裂素（CK）对于驱动植物组织培养中的细胞分裂和增殖至关重要以来，已经过去了半个多世纪。此后，细胞分裂素已成为植物细胞周期和众多发育过程的主要调节因子。最近，越来越多的证据表明，细胞分裂素在减轻非生物和生物胁迫方面发挥作用。细胞分裂素对于保护植物免受过度光照以及光周期改变所产生的一种独特的非生物胁迫至关重要。其次，细胞分裂素在不断变化的环境中也表现出多胁迫恢复力。此外，细胞分裂素的稳态也受到几种形式胁迫的影响。因此，本文详细讨论了细胞分裂素在应对胁迫中的多种作用及其与其他激素的相互作用。在农业方面，了解细胞分裂素在不断变化的环境条件下的作用过程有助于利用这种植物激素来提高生产力。通过这篇综述，我们简要描述了细胞分裂素在非生物挑战下增强植物生长性能的生物学作用以及细胞分裂素诱导胁迫耐受性的潜在机制。此外，本文还提出了一种利用生物技术工具修饰细胞分裂素途径中的基因以培育植物非生物胁迫耐受性的策略。此处提供的信息将有助于更好地理解细胞分裂素在植物中的功能及其在种植系统中的有效研究。
