Arabidopsis LFR, a SWI/SNF complex component, interacts with ICE1 and activates and expression in cold acclimation.

Low temperatures restrict the growth and geographic distribution of plants, as well as crop yields. Appropriate transcriptional regulation is critical for cold acclimation in plants. In this study, we found that the mutation of Leaf and flower related (LFR), a component of SWI/SNF chromatin remodeling complex (CRC) important for transcriptional regulation in Arabidopsis (), resulted in hypersensitivity to freezing stress in plants with or without cold acclimation, and this defect was successfully complemented by .
