Abstract
With continued economic development in Asia the demand for high yielding varieties with premium grain quality traits is set to increase. This presents a significant challenge to plant breeders because varieties must be tailored to meet regional preferences. It is already apparent that traditional breeding techniques cannot meet this challenge and so emerging genomics technologies will have to be utilized. Genome editing tools afford the ability to efficiently and precisely manipulate the genome. Among these, the bacterial clustered, regularly interspaced, short palindromic repeat (CRISPR) associated protein 9 (Cas9) or CRISPR-Cas9 has emerged as the easiest, most economic, and efficient technology to undertake genome editing in rice. This technique allows precise site-specific gene modification or integration. In this chapter we present a method for utilizing CRISPR-Cas9 for improving grain quality traits in rice; this should enable molecular breeders to quickly and efficiently produce high yielding rice varieties tailored to meet specific cultural and regional requirements for grain quality.
