Role of MAPK in regulation of ROS under environmental stress

Author(s):

Abstract:
Plants confront many abiotic and biotic factors like diseases, insect, salt, drought, mineral stresses, heat and cold stress throughout their life cycle. As a result plant shows a complex signaling cascade that is mitogen activated protein (MAP) Kinase pathway; when it encounters with different environmental stresses it gives a particular response against it. Here MAPK activated by the ROS, which act as a secondary messenger it is when the plant get any environmental stress there is an increase in the Abscisic acid (ABA) that is through phosphorelay mechanism and hence activates ABA pathway. ROS leads to enhance when plant encounter with different environmental stresses and this results in the programmed cell death (PCD) and to avoid such higher production of ROS plants scavenges with antioxidants enzymes and metabolites. Counteract to scavenge toxic ROS and furthermore the plant combat and survive under stressed conditions.
