Application and Prospect of Gene Editing in Forage Grass Breeding

doi:10.11983/CBB22280

Abstract

Abstract: Gene editing technology can manipulate the genome of organisms precisely and directionally. It is one of the most eye-catching subversive technologies in the field of life sciences, and has become the key technology in breeding of agriculture and animal husbandry. Recently, the demand for high-yield and high-quality forage grass are increasing in China, therefore, it is urgent to cultivate high-quality forage grass varieties with independent intellectual property rights. Here, we briefly reviewed the development of gene editing technology and its application in agricultural breeding, summarized the research progress in genome editing of gramineous and leguminous forage, and prospected the future direction of molecular module-based technology in forage grass breeding using genome editing.

Key words: forage grass, gene editing, breeding technology, molecular module-based design breeding
