A recent study by Sang et al. successfully demonstrated the simultaneous editing of SBEIIb to develop rice germplasm with an enhanced resistant starch composition, without compromising palatability. This research reveals the unique advantages of promoter engineering in optimizing resistant starch content while preserving palatability achieved through precise modulation of starch biosynthetic and regulatory enzymes, outperforming conventional gene editing approaches. Such findings pave the way for developing elite genotypes with the potential to reduce the societal burden of chronic diseases and satiety management.
