A novel plant genome editing CRISPR/Cas9 System: To modify stress tolerance responses in plants
2019
The plant genome modification by Crispr/Cas9 system is gaining ground. In molecular biology, the use of this indispensable tool works on the basis of target recognition due to the existence of a short protospacer adjacent motif (PAM) that is complementary to the desired strand. The components of the genome-editing tool are guide RNA, Cas9 protein. The mechanistic nature of CRISPR/ Cas9 technology i.e. adaptation, expression and interference lead the desirable mutations in the crop plants. According to the need one can use the different types of programmable DNA targeting and editing platform type. The goal of this review is to provide an idea of the production of stress-tolerant crops. The molecular perception from structural and mechanistic research grant a groundwork for rational engineering for the production of plants that can withstand different kinds of stress.
