| Outline of Final Research Achievements |
Plant MRS2 proteins may play a role in Mg2+ transport. Magnesium and aluminum transport activity and Al inhibition of Mg2+ transport of 3 Arabidopsis thaliana MRS2 proteins and 2 Oryza sativa MRS2 proteins were analyzed using purified MRS2 proteins reconstituted into liposomes and functional complementation assay with Escherichia coli mutants. The results showed that these MRS2 proteins could transport Mg2+, but their Al sensitivity was much different among the MRS2 proteins.
