CRISPR CAS FOR BRINGING DESIRED TRAITS IN CROPS

The projected surge in the global population, concomitant with escalating environmental perturbations, necessitates the sustainable production of high quality food to ensure long term food security. In order to overcome this major undertaking, adaptation of innovative, resilient and science driven agricultural strategies has been considered to be an essential step in plant biotechnology. Advanced biotechnological approaches like genome editing with site directed mutagenesis permit to step forward towards new cultivar with desirable traits in economically important crops Latterly, Zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspersed short palindromic repeats(CRISPR)/CRISPR associated protein 9 system has revolutionised the plant breeding system with exceptional achievements. On that account, the present review re-evaluates and discusses the information on genome editing technologies specially CRISPR/Cas9 approach in detailtogether with complete mechanism of CRISPR/Cas, problem and future aspects of the approach aiming to develop desirable agronomic genetic traits.
