Crispr-Cas Mediated Crop Improvement in Rice: A Review

Abstract

Rice is the staple food crop that is grown across the globe due to its resilience to climatic conditions. Cereals are the predominant food grains consumed by the majority of the population across the globe, with rice alone feeding 50% of the global populace. In order to feed the geometrically rising population, there is a need for a dramatic upsurge in rice production levels. But climate change is one of the causes resulting in the rising of various biotic and abiotic stresses. The advancement of science had resulted in the development of Genome editing technologies like clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9), transcription activator-like effectors nucleases (TALENs), and zinc-finger nucleases (ZFNs). Among these techniques, due to ease of application, and high precision crisper-cas technology had emerged as a solution to overcome various obstacles in the journey of enhancing production levels of rice. In this, we will review various improvements made in the rice crop using crispercas which ultimately led to enhanced production.
