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.
Keywords: Abiotic, CRISPR, Plant breeding, RNA interference (RNAi), Stress.
