OsCIPK7 point‐mutation leads to conformation and kinase‐activity change for sensing cold response

Calcineurin B-like interacting protein kinases (CIPKs) play important roles via environmental stress. However, less is known how to sense the stress in molecular structure conformation level. Here, an OsCIPK7 mutant via TILLING procedure with a point mutation in the kinase domain showed increased chilling tolerance, which could be potentially used in the molecular breeding. We found that this point mutation of OsCIPK7 led to a conformational...
