The mitogen-activated protein kinase (MAPK) pathway is an important signalling event associated with every aspect of plant growth, development, yield, abiotic and biotic stress adaptation. Being a central metabolic pathway, it is a vital target for manipulation for crop improvement. In this review, we have summarised recent advancements in understanding involvement of MAPK signalling in modulating abiotic and biotic stress tolerance, architecture and yield of plants. MAPK signalling cross talks with reactive oxygen species (ROS) and abscisic acid (ABA) signalling events in bringing about abiotic stress adaptation in plants. The intricate involvement of MAPK pathway with plant's pathogen defence ability has also been identified. Further, recent research findings point towards participation of MAPK signalling in shaping plant architecture and yield. These make MAPK pathway an important target for crop improvement and we discuss here various strategies to tweak MAPK signalling components for designing future crops with improved physiology and phenotypes.
丝裂原活化蛋白激酶（MAPK）途径是与植物生长、发育、产量、非生物和生物胁迫适应的各个方面相关的重要信号事件。作为一种中央代谢途径，它是作物改良的重要操纵目标。在这篇综述中，我们总结了最近在理解 MAPK 信号在调节植物的非生物和生物胁迫耐受性、结构和产量方面的作用方面的进展。MAPK 信号与活性氧（ROS）和脱落酸（ABA）信号事件的交叉对话，使植物适应非生物胁迫。MAPK 途径与植物病原体防御能力的复杂关系也已被确定。此外，最近的研究结果表明 MAPK 信号参与了植物结构和产量的形成。这些使得 MAPK 途径成为作物改良的重要目标，我们在这里讨论了各种策略来调整 MAPK 信号组件，以设计具有改善的生理学和表型的未来作物。
