A cDNA clone (AtPUMP) encoding a plant uncoupling mitochondrial protein was isolated from Arabidopsis thaliana . The cDNA contains an open reading frame of 921 nucleotides encoding 306 amino acids (predicted molecular weight 32 708). The predicted polypeptide is 81% identical and 89% similar to the potato UCP‐like protein, and includes an energy transfer protein motif common to mitochondrial transporters. The AtPUMP gene exists as a single copy in the Arabidopsis genome. The corresponding transcript was expressed in all tissues and was strongly induced by cold treatment. We suggest that the putative AtPUMP protein may play a role in heat‐requiring physiological events in Arabidopsis .
