Chapter 15 - Integrated approaches of “omics” for the improvement of stress tolerance in plants

Abstract

Climate change and increasing environmental stressors are major threats to global food security. Plants are facing various environmental stressors, such as drought, high salinity, and extreme temperatures, which can result in reduced growth and yield. To address these challenges, there is a need to identify genes and pathways involved in stress tolerance in plants. Recent advances in omics technologies, such as genomics, transcriptomics, proteomics, and metabolomics, have provided new opportunities to understand the molecular mechanisms underlying stress tolerance in plants. Integrated omics approaches have been used to identify the relationship between gene expression, protein abundance, and metabolic pathways under stress conditions. For example, integrating transcriptomic and proteomic data can provide insight into the relationship between gene expression and protein abundance under stress conditions. Similarly, integrating metabolomic and proteomic data can provide insight into the relationship between metabolic pathways and protein abundance under stress conditions.
