Application of CRISPR-Mediated Gene Editing for Crop Improvement.

Plant gene editing has become an important molecular tool to revolutionize modern breeding of crops. Over the past years, remarkable advancement has been made in developing robust and efficient editing methods for plants. Despite a variety of available genome editing methods, the discovery of most recent system of clustered regularly interspaced short palindromic repeats-CRISPR-associated proteins (CRISPR-Cas) has been one of the biggest advancement in this path, with being the most efficient approach for genome manipulation. Until recently, genetic manipulations were confined to methods, like Agrobacterium-mediated transformations, zinc-finger nucleases, and TAL effector nucleases. However this technology supersedes all other methods for genetic modification. This RNA-guided CRISPR-Cas system is being rapidly developed with enhanced functionalities for better use and greater possibilities in biological research. In this review, we discuss and sum up the application of this simple yet powerful tool of CRISPR-Cas system for crop improvement with recent advancement in this technology.
