Abstract: | Mitochondrial inner membrane uncoupling proteins (UCP) catalyze a proton conductance that dissipates the proton electrochemical
gradient established by the respiratory chain, thus affecting the yield of ATP synthesis. UCPs are involved in mitochondrial
energy flow regulation and have been implicated in oxidative stress tolerance. Based on the global gene expression profiling
datasets available for Arabidopsis thaliana, in this review we discuss the regulation of UCP gene expression during development and in response to stress, and provide interesting insights on the possible existence
of epigenetic regulation of UCP expression. |
