Environmental factors that plants face during their life cycle are dynamic in nature. Plants require adequate amount of water for their growth and development. At the event of moisture deficit in the soil, the water potential in the cells drastically reduced. Under salt stress, plants succumb to salt injuries in addition to dehydration. Plants try to combat such situation by adopting a variety of mechanisms, including closure of stomata that limits water loss and exclusion of Na+ to reduce salt injury. The process starts with stress signal perception, transduction of signal following different pathways and ultimately activation of regulatory proteins or even stress responsive genes to combat the hindrance to normal growth and development caused due to moisture deficit. In the present review, the authors presented a detailed overview of the signaling process in plants under drought and salt stress. | Signal transduction in plants under drought and salt stress - An overview
