| Abstract: |
This article discusses the development of high-resistant starch rice through the simultaneous editing of two genes, SS3a and SS3b, which encode soluble starch synthase. Resistant starch (RS) is beneficial for human health as it is not easily digested and can contribute to the prevention of blood sugar-related and intestinal-related diseases. The researchers used CRISPR/Cas9 genome editing technology to create mutants of SS3a and SS3b in rice, resulting in increased RS content in the grains. The study found that SS3b mutation had a synergistic effect with SS3a mutation in increasing RS content. These findings provide a new strategy for breeding rice varieties with high RS content and contribute to understanding the functions of starch synthase-related genes in cereals.
