A research team led by Assistant Professor Chetphilin Suriyasak<\/span><\/span> and Professor Yushi Ishibashi<\/span><\/span> of the Environment and Food Unit<\/a> and the Sustainable Food Resource Design Research SIF<\/a> has uncovered a novel mechanism by which high temperatures during the rice grain-filling stage induce an \u201cepigenetic memory\u201d in seeds through DNA methylation. The study further revealed that this memory alters gene expression and agricultural traits\u2014including yield\u2014in subsequent generations.<\/p>\n

These findings suggest that, in response to increasing heat stress caused by climate change, it may become possible to regulate crop traits through environmental design during seed formation\u2014without modifying genetic sequences\u2014by utilizing the \u201cepigenomic memory\u201d of seeds. In the future, this approach is expected to contribute to the development of climate-adaptive cultivation strategies, optimization of seed production and seedling cultivation processes, and technologies for stabilizing crop yields.<\/p>\n
