Abstract
Methods and materials for modulating aluminum tolerance in plants are disclosed. For example, nucleic acids encoding aluminum tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased tolerance to aluminum and methods of increasing plant yield in soil containing elevated levels of aluminum.
Claims9
A method of increasing plant yield in soil containing elevated levels of Al3+, said method comprising growing a plant comprising an exogenous nucleic acid on soil having an elevated level of Al3+, said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence, wherein the nucleotide sequence has 90 percent or greater sequence identity to the nucleotide sequence set forth in SEQ ID NO:365 or wherein the nucleotide sequence encodes a polypeptide having 90 percent or greater sequence identity to the amino acid sequence set forth in SEQ ID NO:366, and wherein yield of said plant is increased as compared to the corresponding yield of a control plant that does not comprise said nucleic acid, wherein the regulatory region is heterologous with respect to the nucleotide sequence.
A method of increasing tolerance of a plant to elevated levels of aluminum, said method comprising
- a) introducing into a plurality of plant cells an exogenous nucleic acid comprising a regulatory region operably linked to a nucleic acid sequence, wherein the nucleotide sequence has 90 percent or greater sequence identity to the nucleotide sequence set forth in SEQ ID NO:365 or wherein the nucleotide sequence encodes a polypeptide having 90 percent or greater sequence identity to the amino acid sequence set forth in SEQ ID NO:366;
- b) producing a plant from said plant cell;
- and
- c) growing said plant on soil having an elevated level of Al3+, wherein said plant has increased yield as compared to that of a control plant that does not comprise said nucleic acid.
