植物在整个生命周期中会受到许多环境胁迫，其中大部分胁迫都会激活丝裂原活化蛋白激酶（MAPK）途径。MAPKs在几个点上显示串扰，但已知激活和最终反应对特定刺激是特异性的，该特定刺激反过来激活特定的下游靶点。有趣的是，活性氧（ROS）是一种重要的和常见的信使产生的各种环境压力，并被称为激活许多MAPK。ROS在不同的环境刺激中激活类似的MAPK，显示出不同的下游靶点，具有不同的特异性反应。在动物和酵母中，不同浓度和种类的活性氧特异性激活MAPK的机制已得到阐述，但在植物中这方面仍不清楚。本文主要就活性氧介导的MAPK活化的特异性方面作一综述。已尝试审查参与ROS在非生物胁迫介导的MAPK信号，以及它如何区分与生物胁迫。
Plants encounter a number of environmental stresses throughout their life cycles, most of which activate mitogen activated protein kinase (MAPK) pathway. The MAPKs show crosstalks at several points but the activation and the final response is known to be specific for particular stimuli that in-turn activates specific set of downstream targets. Interestingly, reactive oxygen species (ROS) is an important and common messenger produced in various environmental stresses and is known to activate many of the MAPKs. ROS activates a similar MAPK in different environmental stimuli, showing different downstream targets with different and specific responses. In animals and yeast, the mechanism behind the specific activation of MAPK by different concentration and species of ROS is elaborated, but in plants this aspect is still unclear. This review mainly focuses on the aspect of specificity of ROS mediated MAPK activation. Attempts have been made to review the involvement of ROS in abiotic stress mediated MAPK signaling and how it differentiates with that of biotic stress.
