Salinity is one of the major agricultural constraints exhibiting severe damage to crop productivity. Multivariate signaling pathways trigger plant’s tolerance against salt stress and promote survival via restoring cellular homeostasis. These signal transduction pathways comprise of osmotic and ionic homeostasis pathways, detoxification response pathways for repair and injury control and the growth regulation signaling pathways. The salt overly sensitive (SOS) pathway represents another prominent signaling pathway, arising as a major defence strategy in controlling ion homeostasis. Additionally, the downstream adaptive responses against salinity stress are prompted by mitogen-activated protein kinase (MAPK) and sucrose non-fermenting 1-related protein kinase 2 pathways. Recent investigations suggest that reactive oxygen species (ROS) have a major role in regulating the crosstalks of stress-induced hormonal signaling and endogenously elicited redox and metabolite signals. Thus, the aim of this chapter is to focus on the salt stress-mediated signal transduction pathways including major plant transcription factor (TF) families coordinating regulatory networks underlying salt stress tolerance.
