Omics’ Approaches to Analysis of Stress Response Genes in Medicinal Plants

Global agricultural productivity is under severe pressure from climate change, which is anticipated to worsen in the future years. The global population is expanding quickly, and climate change is accelerating. In 2050, there will be 9.7 billion people on the planet, according to estimates. A significant hunger issue is being caused by the fact that present agriculture production is insufficient to feed the world's 7.9 billion inhabitants. One of the main issues limiting agricultural output is abiotic stress. Understanding the molecular mechanisms underlying plants' abiotic stress response is crucial in the current phase of persistent climate change. The emergence of -omics techniques offers crucial tactics for encouraging profitable field research, supporting inquiries ranging from standard models to an expanding range of species, tolerant, and sensitive genotypes. This chapter discusses all of the molecular alterations that occur in stressed plants and emphasizes the novel discovery made possible by the integration of omics. The majority of omics technologies include extremely high throughput, quick data production rates, and massive outputs. The advancements in our understanding of plant biology in the modern era are clearly attributable to these technologies. As a result, the emphasis in this article is on omics studies and an ecological approach to abiotic stress tolerance in plants.
