Chinese scientists identify gene that could make rice perennial and boost yields

Chinese researchers have discovered a gene that could allow rice to regrow year after year, potentially significantly increasing yields and reducing farming costs, according to state media reports.

Scientists at the Center for Excellence in Molecular Plant Sciences at the Chinese Academy of Sciences have uncovered a genetic mechanism that enables plants to survive winter and regenerate from their roots. This breakthrough could turn rice from an annual crop into a perennial one.

The study found that a genomic region called EBT1 plays a key role in extending a plant’s lifespan by suppressing aging signals and maintaining its vegetative state. Using this knowledge, researchers developed a new rice variety, G43, which produces around 70 branches compared with 12 branches in conventional varieties.

The team also combined the EBT1 gene with other growth-related genes, resulting in plants capable of surviving at least two years under suitable field conditions. Experts say the findings could support long-term efforts to convert annual crops into perennials, improving yields while reducing labor and input costs.

However, further field trials and large-scale validation are needed before the new varieties can be widely adopted. Researchers emphasize that developing perennial crops is increasingly important given climate change and rising global food demand.
