Crispr / cas: a new horizon in crop improvement

Human population has grown exponentially over the last several decades, making the problem of feeding an ever-growing population a huge concern. In such situations, augmentation in agricultural production is the utmost need for supplying nutrition along with food to the mankind. Moreover, conventional breeding methods are not enough to meet this demand due to its high time-consumption and labourintensive nature. Therefore, to vanquish these circumstances, CRISPR-Cas comes into the field of molecular approach to provide an alternative to the conventional procedures. CRISPR has played a crucial role in the progress in genome editing studies since last few decades. Base editing, knock out or knock in of desirable genes, fine tuning of several genes, promotion of antiviral defense, and alteration of various demanding biochemical pathways through this specific gene editing system has proven its ability to spread new wings for accelerating crop advancement in last few years. In a nutshell, this chapter mainly aims at the execution of CRISPR/Cas system towards the revolutionary approaches of future plant breeding, along with a short overview and future endeavour
