| Research Abstract |
The mechanisms for the expression and function of aluminum-activated malate transporter (ALMT1) of wheat were analyzed. We demonstrated that the variation of the upstream sequence of ALMT1 is strongly correlated to the aluminum sensitivity of wheat, and that three acidic amino acids within hydrophilic C-terminal domain of ALMT1 is required for the activation of transport function by aluminum. Furthermore, we found that the functions of several ALMT homologues in Arabidopsis are related to aluminum resistance and closing stomata, suggesting that ALMT proteins comprise a family of anion transporters, possessing diverse functions.
