In recent years, the frequent occurrence of extreme weather has severely impacted wheat yields, causing widespread damage due to low temperatures in many parts of the country. This led to extensive death of wheat plants, significantly affecting wheat production in China. Exploring and understanding the genes related to the regulation of wheat's cold resistance and deciphering their control mechanisms can provide crucial genetic resources and technological support for breeding wheat with improved cold resistance. The research team led by Professor Chen Feng from the College of Agriculture has published a research article titled 'ATaSnRK1α modulates TaPAP6L-mediated wheat cold tolerance through regulating endogenous jasmonic acid' in the internationally renowned academic journal Advanced Science.
The study cloned two key genes related to cold resistance, TaSnRK1α and TaPAP6L, and confirmed their low-temperature response functions and regulatory mechanisms. The research proposes a new mechanism by which the TaSnRK1α-TaPAP6L module enhances wheat cold resistance by regulating the content of jasmonic acid (JA). This discovery not only provides important genetic resources for stress-resistant wheat breeding in China but also lays a theoretical foundation for understanding the genetic basis and regulatory mechanisms of wheat's response to low temperatures.
