Interactions between Wheat Root System and Salt Stress Environments

Wheat (Triticum aestivum) is a dominant and staple crop around the globe; hence, a large portion of the population depends on this crop for their daily food consumption. However, wheat faces several environmental stressors in its surroundings that elicit a devastating effect on its productivity and yield. Therefore, wheat relies on several tolerance strategies to enhance its survival and yield capacity under sudden environmental perturbations, including salt stress. Wheat root systems respond to salt stress contact by coordinating regulatory actions that impact growth, physiology, and yield tolerance. The root systems-mediated signaling networks could be considered as salt tolerance messengers, as they pivotally control and lower salt-induced oxidative toxicities in wheat plants. In response to salt stress exposure, the root system induces adaptive modifications in their morphological, physiological, and metabolic well-being to overcome salt severity to a greater extent. These mechanisms are pivotal in maintaining the equilibrium between the antioxidant metabolisms, providing relief from salt-mediated ionic, osmotic, and oxidative disorders. This can be further enhanced through biotechnological interventions encompassing omics strategies to finely tune root behavior, aiming to promote and protect the wheat productivity in response to salt environments. Thus, the present chapter highlights and focuses on the effects of salt stress on wheat plants and explains how root systems can help ameliorate plant morbidities. With a comprehensive understanding of root-mediated salt acclimatization, researchers could augment wheat defense mechanisms associated with the current and future concern for transgenic development to improve food security standards and crop nutrition values.
