Phytohormones are chemical substances that in minute concentration instruct a plethora of developmental and physiological responses in plants. These signal molecules synthesized within the plant body are referred to as plant growth regulators. The available literature revealed that manipulation of phytohormonal content could be a promising approach towards augmentation of environmental stress tolerance in crop plants. They play pivotal role in acclimatization against unstable environmental extremes. Gibberellins are plant hormones affecting germination, stem elongation, flowering, abolition of dormancy, determination of sex expression, leaf and fruit senescence, and enzymatic stimulation. The uncertainty in climatic condition and over expanding population has led to a heap of abiotic stresses in plants. Salinity, high temperature, chilling, freezing, heavy metals, drought, flooding, allelochemicals, and radiation are the stresses that hinder development of plants. The perception of these stresses by plants occurs in a highly coordinated and interactive manner by triggering the activation of a myriad of elaborate signaling networks in which phytohormones play a significant role. The present review describes biosynthesis, signaling, and the potential roles of gibberellins as a tool in mitigating stress, increasing growth, development, and tolerance in plants. In future, revelations evolving the comprehensive knowledge to understand the relationship of plant growth regulators and stress conditions are discussed. This review also enlightens the latest research progress in GA signaling and its crosstalk with other hormonal pathways, underlying the multitude role of DELLA proteins with components of other hormonal signaling pathways.

减轻赤霉素在各种环境线索中的策略及其与植物中其他激素途径的串扰：综述

植物激素是一种化学物质，其浓度极低，可指导植物的大量发育和生理反应。这些在植物体内合成的信号分子被称为植物生长调节剂。现有文献表明，操纵植物激素含量可能是增强作物对环境胁迫耐受性的一种有前途的方法。它们在适应不稳定的极端环境方面发挥着关键作用。赤霉素是影响发芽、茎伸长、开花、休眠解除、性别表达确定、叶和果实衰老以及酶促刺激的植物激素。气候条件的不确定性和人口的过度扩张导致了植物中的大量非生物胁迫。盐度、高温、寒冷、冰冻、重金属、干旱、洪水、化感化学物质和辐射是阻碍植物发育的压力。植物对这些压力的感知以高度协调和互动的方式发生，通过触发无数复杂的信号网络的激活，植物激素在其中发挥重要作用。本综述描述了赤霉素作为减轻压力、促进植物生长、发育和耐受性的工具的生物合成、信号传导和潜在作用。将来，将讨论发展综合知识以了解植物生长调节剂与胁迫条件之间关系的启示。这篇综述也启发了 GA 信号传导及其与其他激素途径的串扰的最新研究进展，
