Liu Hongtao's research group reveals the mechanism by which ambient temperature regulates the stability of blue light receptor cryptoflorin protein

On September 1, 2021, the international academic journal The Plant Cell published an online publication titled "Light-Response Bric-A-BracK/Tramtrack/Broad proteins mediate cryptochrome 2 degradation in response to" by Liu Hongtao's research group from the Center for Excellence in Molecular Plant Science, Chinese Academy of Sciences.

Under natural conditions, light and temperature usually change synergistically, and they jointly regulate important traits such as plant elongation, flowering time, endogenous biological clock, seed germination, and plant type

Liu Hongtao's research group found that the stability of CRY2 protein is regulated by environmental temperature, and CRY2 protein is degraded through 26S proteasome pathway at low environmental temperature

Ma Libang, a doctoral student at the Center for Excellence in Molecular Plant Science, Chinese Academy of Sciences, is the first author of the paper, and researcher Liu Hongtao is the corresponding author
