SbSTP20, a sorghum monosaccharide transporter, is essential for endosperm hexose influx and sub-aleurone thickening, boosting grain protein and micronutrients.
- Why it matters: Biofortification in sorghum is limited by a breeding trade-off between yield and nutritional quality, and domestication can erase beneficial grain-quality alleles.
- What they did: The authors ectopically expressed SbSTP20 in developing sorghum grains, used CRISPR to edit Sbstp20, and tested a natural SbSTP20thick variant for hexose influx, sub-aleurone thickness, and nutrient composition.
- The result: Sbstp20 editing reduced hexose influx and increased sub-aleurone layers with 6.6–7.5% higher grain protein and enriched Fe and Zn; SbSTP20thick improved nutrition without changing grain size or thousand-grain weight and raised metabolizable energy by up to 6% in swine digestion.
