Low temperature adversely affects plant growth and crop yield. The studies largely focus on cold stress (<4 degrees C), while the response upon low temperature higher than 4 degrees C is rarely documented so far. Here, we isolate a GTP-binding protein beta subunit like gene TaGPBL. TaGPBL is responsive to low temperature of 16 degrees C, and its ectopic overexpression in Arabidopsis results in more remarkable growth restriction under 16 degrees C, but has no effect under 22 degrees C. TaGBPL overexpression reduces the induction of cold-inducible genes and the activities of ROS scavengers and producers in lower temperature dependent manner. The data indicate that TaGBPL participates in the response to low temperature, which provides evidence for deepening our insight into the role of G-protein in temperature perception and signaling transduction.
