|a VQ motif-containing proteins play important roles in plant abiotic and biotic stresses. In this study, we cloned the VQ protein gene TaVQ4-D that is induced by drought stress. Arabidopsis and wheat plants overexpressing TaVQ4-D showed increased tolerance to drought stress. In contrast, wheat lines in which TaVQ4-D expression had been silenced showed decreased drought tolerance. Under drought stress conditions, the contents of superoxide dismutase and proline increased and the content of malondialdehyde decreased in transgenic wheat plants overexpressing TaVQ4-D compared with the wild type. At the same time, the expression of reactive oxygen species-scavenging-related genes and stress-related genes was up-regulated. However, plants of TaVQ4-D-silenced wheat lines showed decreased activities of antioxidant enzymes and reduced expression of some stress-related and antioxidant-related genes. In addition, the TaVQ4-D protein physically interacts with two mitogen-activated protein kinases (MPK3 and MPK6) and plays a role in plant drought stress as the phosphorylated substrates of MPK3 and MPK6. In summary, the results of our study suggest that TaVQ4-D can positively regulate drought stress tolerance in wheat
