The changing environment is one of the predominant stressors that negatively influence plant growth, development, quality, and productivity. This is a wide-ranging topic on which numerous studies have been conducted globally to comprehend the physiological, biochemical, and molecular dynamisms operative in plants under challenging conditions. Despite all these efforts, various adaptive mechanisms of plants under the challenging environment remain to be uncovered. Therefore, modern tools and methods for the identification and application of genes, RNAs, and proteins responsible for increased yield and desirable agronomical traits in plants under challenging environments are needed. In the past few decades, plant omics tools are used to understand the deeper molecular tolerance networks in plants in a challenging environment.

This special issue intends to integrate recent omics approaches such as phenomics, genomics, transcriptomics, proteomics, metabolomics, cytomics and interactomics, to make novel advancements in defining the molecular aspects of plant response to the challenging environmental conditions.
