      abstract     = {Mitochondria are important sources of energy in plants and
                      are implicated in coordination of a number of metabolic and
                      physiological processes including stabilization of redox
                      balance, synthesis and turnover of a number of metabolites,
                      and control of programmed cell death. Mitochondrial electron
                      transport chain (mETC) is the backbone of the energy
                      producing process which can influence other processes as
                      well. Accumulating evidence suggests that mETC can affect
                      responses to environmental stimuli and modulate tolerance to
                      extreme conditions such as drought or salinity. Screening
                      for stress responses of 13 Arabidopsis mitochondria-related
                      T- DNA insertion mutants, we identified ndufs8.2-1 which has
                      an increased ability to withstand osmotic and oxidative
                      stresses compared to wild type plants. Insertion in
                      ndufs8.2-1 disrupted the gene that encodes the NADH
                      dehydrogenase [ubiquinone] fragment S subunit 8 (NDUFS8) a
                      component of Complex I of mETC. ndufs8.2-1 tolerated reduced
                      water availability, retained photosynthetic activity and
                      recovered from severe water stress with higher efficiency
                      compared to wild type plants. Several mitochondrial
                      functions were altered in the mutant including oxygen
                      consumption, ROS production, ATP and ADP content as well as
                      activities of genes encoding alternative oxidase 1A (AOX1A)
                      and various alternative NAD(P)H dehydrogenases (ND). Our
                      results suggest that in the absence of NDUFS8.2
                      stress-induced ROS generation is restrained leading to
                      reduced oxidative damage and improved tolerance to water
                      deficiency. mETC components can be implicated in redox and
                      energy homeostasis and modulate responses to stresses
                      associated with reduced water availability.},
