Abstract
Methods and materials for modulating low-nitrogen tolerance levels in plants are disclosed. For example, nucleic acids encoding low nitrogen tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased low-nitrogen tolerance levels and plant products produced from plants having increased low-nitrogen tolerance levels.
Claims16
A method of producing a plant, said method comprising growing a plant cell comprising an exogenous nucleic acid, said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence, wherein said nucleotide sequences encodes a polypeptide comprising an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:828, or wherein said nucleotide sequence comprises a polynucleotide sequence having 95 percent or greater sequence identity to the polynucleotide sequence of SEQ ID NO:827;
- wherein said polypeptide comprises a DUF246 domain;
- and
- wherein a plant produced from said plant cell has an increased level of low-nitrogen tolerance as compared to the corresponding level of low-nitrogen tolerance of a control plant that does not comprise said nucleic acid.
A plant cell comprising an exogenous nucleic acid said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence, wherein said nucleotide sequences encodes a polypeptide comprising an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:828, or wherein said nucleotide sequence comprises a polynucleotide sequence having 95 percent or greater sequence identity to the polynucleotide sequence of SEQ ID NO:827;
- wherein said nucleotide sequence encodes a polypeptide that comprises a DUF246 domain;
- and
- wherein a plant produced from said plant cell has an increased level of low-nitrogen tolerance as compared to the corresponding level of low-nitrogen tolerance of a control plant that does not comprise said nucleic acid.
An nucleic acid comprising a heterologous regulatory region operably linked to a nucleotide sequence, wherein said nucleotide sequences encodes a polypeptide comprising an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:828, or wherein said nucleotide sequence comprises a polynucleotide sequence that has 95 percent or greater sequence identity to a polynucleotide sequence of SEQ ID NO:827, wherein said polypeptide comprises a DUF246 domain.
