ABSTRACT
The dynamics of plasma membrane (PM) protein responses towards changes in abiotic conditions have been one of the fundamental interests of plant research for decades. Salt is among the naturally occurring minerals of soil that affect plant growth and vitality. The salinity of soil takes the shape of stress when the root-water relation is perturbed due to excess accumulation of dissolved mineral solutes. Several crop species, including soybean, are susceptible to flood conditions, which can affect plant germination and vegetative as well as reproductive growth. The role of receptor-like kinases in sensing adverse environmental conditions and activating a downstream signaling cascade via activation of its intracellular kinase domain through phosphorylation is well established. One of the downstream manifestations of several abiotic stresses is the disturbance in plant-water homeostasis. PM-intrinsic aquaporins function as water channels that also transfer carbon dioxide and small uncharged solutes. The phytohormone abscisic acid regulates plant developmental processes and functions as a major player in abiotic stress response.
