Biotic and abiotic stresses are the main constrain of potato ( L.) production all over the world. To overcome these hurdles, many techniques and mechanisms have been used for increasing food demand for increasing population. One of such mechanism is mitogen-activated protein kinase (MAPK) cascade, which is significance regulators of MAPK pathway under various biotic and abiotic stress conditions in plants. However, the acute role in potato for various biotic and abiotic resistance is not fully understood. In eukaryotes including plants, MAPK transfer information from sensors to responses. In potato, biotic and abiotic stresses, as well as a range of developmental responses including differentiation, proliferation, and cell death in plants, MAPK plays an essential role in transduction of diverse extracellular stimuli. Different biotic and abiotic stress stimuli such as pathogen (bacteria, virus, and fungi, etc.) infections, drought, high and low temperatures, high salinity, and high or low osmolarity are induced by several MAPK cascade and MAPK gene families in potato crop. The MAPK cascade is synchronized by numerous mechanisms, including not only transcriptional regulation but also through posttranscriptional regulation such as protein-protein interactions. In this review, we will discuss the recent detailed functional analysis of certain specific MAPK gene families which are involved in resistance to various biotic and abiotic stresses in potato. This study will also provide new insights into functional analysis of various MAPK gene families in biotic and abiotic stress response as well as its possible mechanism.
生物和非生物胁迫是全球马铃薯生产的主要限制因素。为了克服这些障碍，人们采用了许多技术和机制来满足不断增长的人口对食物的需求。其中一种机制是丝裂原活化蛋白激酶（MAPK）级联反应，它是植物在各种生物和非生物胁迫条件下MAPK途径的重要调节因子。然而，MAPK在马铃薯各种生物和非生物抗性中的具体作用尚未完全明确。在包括植物在内的真核生物中，MAPK将信息从传感器传递到响应环节。在马铃薯中，生物和非生物胁迫以及一系列发育反应，包括植物的分化、增殖和细胞死亡，MAPK在多种细胞外刺激的转导中起着至关重要的作用。马铃薯作物中的几种MAPK级联反应和MAPK基因家族可诱导不同的生物和非生物胁迫刺激，如病原体（细菌、病毒和真菌等）感染、干旱、高温和低温、高盐度以及高或低渗透压。MAPK级联反应通过多种机制同步，不仅包括转录调控，还包括蛋白质-蛋白质相互作用等转录后调控。在本综述中，我们将讨论某些特定MAPK基因家族最近的详细功能分析，这些基因家族参与了马铃薯对各种生物和非生物胁迫的抗性。本研究还将为各种MAPK基因家族在生物和非生物胁迫响应中的功能分析及其可能机制提供新的见解。
