New rice gene combo boosts health benefits and changes starch properties.
A study looked at different genes in rice that affect starch content and quality. By combining specific alleles of two genes, SBE3 and GBSS1, researchers created rice lines with varying starch properties. These genetic variations changed the rice's appearance, structure, digestibility, and amylose content. The genes SBE3 and GBSS1 work together to influence the amount of amylose and resistant starch in rice. The expression of other starch-related genes also differed among the rice lines, affecting the overall starch characteristics. This research shows how specific gene combinations can alter the properties of rice starch.
