Researchers at Huazhong Agricultural University in China identified a key gene that significantly increases rice tolerance to extreme heat, maintaining grain quality and performance. The discovery, published on Wednesday (1st) on the magazine website Cellit can represent a decisive advance in the face of the climatic challenges that threaten culture production.
Named QT12, the gene interacts with the NF-Y protein complex and acts as a kind of “firewall” within rice grains. It protects against the effects of intense heat and stabilizes starch and protein synthesis, essential for food quality, explained researcher Li Yibo, corresponding author of the study.
During the heat waves registered last year, the team performed large -scale field tests in the Yangtzé River basin – responsible for about two thirds of national rice production. By introducing the QT12 gene into the hybrid variety “Huazhan”, researchers recorded 49% productivity increases in Wuhan, 78% in Hangzhou and 31% in Changsha.
The discovery offers a new strategy for genetic improvement to ensure stable and high quality harvests even under high temperatures. According to Li, the team has already established partnerships with agricultural companies to accelerate the application of technology in the field.
With the impacts of climate change intensifying, solutions such as QT12 are highlighted as indispensable tools for protecting food safety in extreme heat regions.
