Abstract
Although present in huge abundance in the earth’s crust, the availability of silicon (Si) is very low in soil. But it imparts manifolds benefits on soil and plant health like increasing the yield of crops, stabilization of soil characteristics etc. The uptake of Si in soil and plant is mediated by certain carrier proteins which are present in the root of the crops. Mostly, the Poaceae crops are the efficient users of Si. A major impact of Si in crops is the remediation of biotic and abiotic stress. Globally, salt stress poses a serious hazard to plant development. Numerous studies have been conducted utilizing physiological, molecular genetics and genomic-based techniques in order to investigate the possible mechanisms to regulate the salinity stress through Si application. These studies were carried out in order to get a better understanding of the processes involved. Clarifying silicon's mitigating effects on oxidative stress, Na toxicity and salt-induced osmotic stress has advanced recently. The behavior of silicon in the soil, the processes by which it is absorbed and the function that it plays in plants in the process of warding off salt stress in plants are the primary topics of discussion in this article.
