Abstract

Abstract:

Rice is one of the important food crops in China, and it is also the main food source for more than 3 billion people in the world. In recent decades, crop disease caused by various plant pathogens, climate change and other environmental problems seriously threaten global food security. There is an urgent need for rice plants with high yield and disease resistance, but the traditional breeding methods are complicated and inefficient. On the other hand, the numerous emerging gene editing techniques, such as CRISPR, zinc-finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), base editing (BE) and prime editing (PE), have shown great potential to accelerate rice breeding with increased yield, quality and disease resistance. They are also useful tools of fundamental research of gene function. In this review, we summarized the principles and developments of gene editing technologies, and their application progresses in rice disease resistance genes mining and breeding. Finally, we discussed the prospective applications of gene editing technologies in rice breeding for disease resistance.

Key words: gene editing, rice, CRISPR system, breeding research
