Plant annexins are proteins with multiple functions and roles in plant development and responses to abiotic stresses. We report here the functional analysis of the TdAnn12 annexin protein isolated from Triticum durum Desf. We have previously shown that TdAnn12 expression is highly induced by different abiotic stresses. In the present study, to investigate the physiological and biochemical stress-induced responses, we overexpressed TdAnn12 in tobacco. We demonstrate that transgenic tobacco plants expressing TdAnn12 exhibited enhanced tolerance to salt, osmotic stress and H2O2 at the seedling stage. Under greenhouse conditions, these plants showed tolerance to drought and salt stresses. Moreover, scavenging reactive oxygen species (ROS), higher chlorophyll content, lower lipid peroxidation levels and increased antioxidant activities (peroxidase, catalase and superoxide dismutase) were observed. Finally, accumulation of TdAnn12 in tobacco positively affects the regulation of some stress-related genes (MnSOD, APX1, CAT1, P5CS, NHX1, SOS1 and DREB1A). TdAnn12 interacts directly or indirectly with stress-related genes that could stimulate an adaptive potential to gain tolerance which is not present in non-transgenic (NT) plants. Our results clearly show that overexpression of TdAnn12 in transgenic tobacco improves stress tolerance through the removal of ROS.
