“…The results of the present study show that ABA has altered the stomatal behavior as a signal participating in the opening and closing mechanism of the stomata. Results obtained in present study show that all the pulses taken for the study show the expected response in terms of decrease in stomatal conductance and from the present study it is evident that the exogenous application of ABA not only regulates the stomatal movements but also cause variations in pigment compositions as a result of that it enhances the water use efficiency [30]. ) compared to other treatments.…”

Pulses are a crucial group of crops that supply high-quality protein to complement the protein found in cereal crops for the large vegetarian population. Water scarcity and inefficient water management pose significant challenges to pulse production, which is crucial for food security and sustainable agriculture. This paper focuses on optimizing water utilization in pulse production to enhance crop yields and mitigate the impact on water resources. We explore various strategies and technologies that can improve water-use efficiency, including precision irrigation techniques, soil moisture monitoring, water-saving practices, and genetic improvement programs for drought-tolerant varieties. Additionally, we discuss the benefits of agroforestry systems and crop rotation in enhancing water infiltration and soil health. By implementing these measures, farmers can optimize water utilization, increase pulse yields, and contribute to sustainable agricultural practices. This research highlights the importance of addressing water scarcity in pulse production to ensure food security in the face of changing climatic conditions and growing population demands.

“…This suggests the existence of a biochemical signal from the roots that triggers adaptive mechanisms in the shoot. There is compelling evidence that the abscisic acid (ABA) plays an important role for long-distance signaling considering that the levels of this water-stress associated hormone increases in both xylem sap and leaves controlling stomata closure under stress (Jacobsen et al, 2009;Carvalho et al, 2011;Vijayalakshmi et al, 2014;Ollas and Dodd, 2016). However, several experiments have demonstrated that, under drought conditions, the stomata close can occur independently of the ABA biosynthesis by the roots (Stoll et al, 2000;Augé and Moore, 2002;Holbrook et al, 2002).…”

Plants are sessile organisms that must perceive and respond to various environmental constraints throughout their life cycle. Among these constraints, drought stress has become the main limiting factor to crop production around the world. Water deprivation is perceived primarily by the roots, which efficiently signal the shoot to trigger drought responses in order to maximize a plant's ability to survive. In this study, the tomato (Solanum lycopersicum L.) mutant procera (pro), with a constitutive response to gibberellin (GA), and its near isogenic line cv. Micro-Tom (MT), were used in reciprocal grafting under well-watered and water stress conditions to evaluate the role of GA signaling in root-to-shoot communication during drought stress. Growth, oxidative stress, gene expression, water relations and hormonal content were measured in order to provide insights into GA-mediated adjustments to water stress. All graft combinations with pro (i.e. pro/pro, MT/pro and pro/MT) prevented the reduction of growth under stress conditions without a reduction in oxidative stress. The increase of oxidative stress was followed by upregulation of SlDREB2, a drought-tolerance related gene, in all drought-stressed plants. Scions harboring the pro mutation tended to increase the abscisic acid (ABA) content, independent of the rootstock. Moreover, the GA sensitivity of the rootstock modulated stomatal conductance and water use efficiency under drought stress, indicating GA and ABA crosstalk in the adjustment of growth and water economy.
