A wheat GTP-binding protein like gene reduces tolerance to low temperature in Arabidopsis

Abstract Low temperature adversely affects plant growth and crop yield. The studies largely focus on cold stress ( TaGPBL . TaGPBL is responsive to low temperature of 16 °C, and its ectopic overexpression in Arabidopsis results in more remarkable growth restriction under 16 °C, but has no effect under 22 °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.
