High impact information on ICE1

 

Biological context of ICE1

 

Regulatory relationships of ICE1

  • The ice1 mutation blocks the expression of CBF3 and decreases the expression of many genes downstream of CBFs, which leads to a significant reduction in plant chilling and freezing tolerance [1].
 

Other interactions of ICE1

  • Our results indicate that cold stress responses in Arabidopsis are attenuated by a ubiquitination/proteasome pathway in which HOS1 mediates the degradation of the ICE1 protein [2].
