The alternative oxidase (AOX) of plant mitochondria transfers electrons from the ubiquinione pool to oxygen without energy conservation and prevents the formation of reactive oxygen species (ROS) when the ubiquinone pool is over-reduced. Thus, AOX may be involved in plant acclimation to a number of oxidative stresses. To test this hypothesis, we exposed wild-type (WT) Xanthi tobacco plants as well as Xanthi plants transformed with the Bright Yellow tobacco AOX1a cDNA with enhanced (SN21 and… CONTINUE READING
