HvALMT1 from barley (Hordeum vulgare L.) encodes a protein capable of facilitating the transport of malate and other organic anions when expressed in Xenopus oocytes. The HvALMT1 gene is primarily expressed in guard cells of stomata, in regions behind the root apex and at lateral root junctions. We investigated the function of HvALMT1 in planta by overexpressing it in barley under the control of a constitutive promoter. Transgenic plants expressing HvALMT1 at levels four to 9-fold greater than...[Show more]
