The presence of phyto-hormones in plants at relatively low concentrations plays an indispensable role in regulating crop growth and yield. Salt stress is one of the major abiotic stresses limiting cotton production. It has been reported that exogenous phyto-hormones are involved in various plant defense systems against salt stress. Recently, different studies revealed the pivotal performance of hormones in regulating cotton growth and yield. However, a comprehensive understanding of these exogenous hormones, which regulate cotton growth and yield under salt stress, is lacking. In this review, we focused on new advances in elucidating the roles of exogenous hormones (gibberellin (GA) and salicylic acid (SA)) and their signaling and transduction pathways and the cross-talk between GA and SA in regulating crop growth and development under salt stress. In this review, we not only focused on the role of phyto-hormones but also identified the roles of GA and SA responsive genes to salt stress. Our aim is to provide a comprehensive review of the performance of GA and SA and their responsive genes under salt stress, assisting in the further elucidation of the mechanism that plant hormones use to regulate growth and yield under salt stress.
植物中低浓度的植物激素的存在在调节作物生长和产量方面起着不可或缺的作用。盐胁迫是限制棉花生产的主要非生物胁迫之一。据报道，外源植物激素参与了植物对盐胁迫的各种防御系统。最近，不同的研究揭示了激素在调节棉花生长和产量中的关键作用。然而，对于这些调节棉花在盐胁迫下生长和产量的外源激素，我们缺乏全面的了解。在这篇综述中，我们重点阐述了外源激素（赤霉素（GA）和水杨酸（SA））及其信号转导途径以及 GA 和 SA 之间的交叉对话在调节作物生长和发育中的作用。在这篇综述中，我们不仅关注植物激素的作用，还确定了 GA 和 SA 响应基因在盐胁迫下的作用。我们的目的是提供一个全面的综述，介绍 GA 和 SA 及其响应基因在盐胁迫下的表现，以协助进一步阐明植物激素在盐胁迫下调节生长和产量的机制。
