Rice Gene Variant QT12 Boosts Heat Resistance

The story of the rice gene variant QT12 began in 2012 with a comprehensive research mission to identify genes that confer heat resistance in rice. This extensive effort, primarily led by researchers at Huazhong Agricultural University, culminated in the discovery of QT12, a natural gene variant that significantly boosts rice's heat resistance. Published in May 2025, the research revealed that QT12 acts as a natural 'on-off system' that protects rice grains from heat stress, leading to increased yields (31-93%) and improved grain quality even during heatwaves. Large-scale field trials conducted in 2024 validated its effectiveness. Currently, the research team is collaborating with agricultural companies to integrate QT12 into commercial breeding programs, offering a promising solution to safeguard global food supplies against the escalating threat of climate change and rising temperatures.
