CRISPR/CAS9 Technologies to Enhance Tolerance to Abiotic Stress in Crop Plants

Ravinder Singh*, Rajani Gupta, Renu Bhardwaj and Rattandeep Singh*

Abstract

Plants can identify and cope up with biotic and abiotic stressors, thus resulting in a reduction in agricultural production significantly. Currently, the primary goal of plant breeders is to develop the ability to tolerate multiple stress conditions without lowering the productivity of the crop. However, numerous attempts have failed to release these plants due to persistent divergence between growth and resistance to stressors. Such strategies are not appropriate to effectively enhance characteristics and ensure potential environmental impact. Genome editing approaches and RNA interference (RNAi) technique has been used to develop plants resistant to different environmental changes. Newly developed approaches such as CRISPR are used to grow new varieties that have external stressors tolerance and reduce a vital yield loss. This chapter addresses the use of CRISPR/CAS techniques to improve the stress tolerating ability of the plants.
