A number of consequences of climate change, notably salinity, put global food security at risk by impacting the development and production of lentils. Salinity-induced stress alters lentil genetics, resulting in severe developmental issues and eventual phenotypic damage. Lentils have evolved sophisticated signaling networks to combat salinity stress. Lentil genomics and transcriptomics have discovered key genes and pathways that play an important role in mitigating salinity stress. The development of saline-smart cultivars can be further revolutionized by implementing proteomics, metabolomics, miRNAomics, epigenomics, phenomics, ionomics, machine learning, and speed breeding approaches. All these cutting-edge approaches represent a viable path toward creating saline-tolerant lentil cultivars that can withstand climate change and meet the growing demand for high-quality food worldwide. The review emphasizes the gaps that must be filled for future food security in a changing climate while also highlighting the significant discoveries and insights made possible by omics and other state-of-the-art biotechnological techniques.

Digestive issues are recognized as significant contributors to various chronic diseases, including obesity, diabetes, and cardiovascular disease. Barley, a traditional grain, offers considerable promise in addressing these health challenges due to unique nutritional and bioactive compounds. This review examines the therapeutic potential of various parts of barley, underutilized resource, for chronic disease prevention and management. ology: A comprehensive literature search was conducted across multiple databases like Google Scholar, PubMed, and ISI Web of Science, to identify nutritional components and functional ingredients in barley that contribute to gut health and chronic disease mitigation. The finding suggests that humans digest barley starch more slowly than wheat and rice, which benefits chronic disease management. Barley's high-molecular-weight β-glucan high content acts as a prebiotic, promotes gut health through microbiome modulation and short-chain fatty acid production, potentially preventing colon cancer and boosting immunity. Recent studies on exploring barley grass of high land showed functional ingredients such as flavonoids, saponarin lutonarin, superoxide dismutase, gamma-aminobutyric acid, polyphenols K, Ca, Se, tryptophan chlorophyll, and vitamins, suggesting potential for enhanced antioxidant activity and improved management of chronic conditions like diabetes, cholesterol, hypertension, cardiovascular health, liver protection, and even boosted immunity. This review underscores the therapeutic potential of barley and its components in chronic disease management, highlighting the need for well-designed clinical trials to translate these findings into effective interventions.
