Abstract
Abiotic stresses extensively reduce agricultural crop production globally. Traditional breeding approaches have been widely used to mitigate the risks of abiotic stresses. The discovery of gene editing technology for modifying stress-responsive genes and associated molecular networks has paved the foundation for sustainable crop management against environmental stress. Integrated approaches based on functional genomics and transcriptomics are now expanding the opportunities to elucidate the molecular mechanisms underlying abiotic stress responses. This review summarizes some of the features and weblinks of plant genome databases related to abiotic stress genes utilized for crop improvement. Clustered, regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas) based gene-editing tool has revolutionized stress tolerance research due to its simplicity, versatility, adaptability, flexibility, and broader applications. However, off-target and low cleavage efficiency hinder the successful application of CRISPR/Cas systems. Computational tools have been developed for designing highly competent gRNA with better cleavage efficiency. This powerful genome editing tool offers tremendous crop improvement opportunities, overcoming conventional breeding techniques' shortcomings. Furthermore, we also discuss the mechanistic insights of the CRISPR/Cas9-based genome editing technology. This review summarizes the current advances in understanding plant species' abiotic stress response mechanism and applying the CRISPR/Cas system genome editing technology to develop crop resilience against drought, salinity, temperature, heavy metals, and herbicides.
