Key message: Here, a functional characterization of a wheat MSR has been presented: this protein makes a contribution to the plant’s tolerance of abiotic stress, acting through its catalytic capacity and its modulation of ROS and ABA pathways. Abstract: The molecular mechanism and function of certain members of the methionine sulfoxide reductase (MSR) gene family have been defined, however, these analyses have not included the wheat equivalents. The wheat MSR gene TaMSRA4.1 is inducible by salinity and drought stress and in this study, we demo...
