Dwarf7 (dwf7) mutants and polypeptides, as well as methods of using the same, are disclosed. The dwf7 polynucleotides can be used in the production of transgenic plants which display at least one dwf7 phenotype, so that the resulting plants have altered structure or morphology.
1. An isolated polynucleotide comprising a nucleic acid sequence encoding a polypeptide having the amino acid sequence set forth in SEQ ID NO:23.
2. A recombinant vector comprising the isolated polynucleotide of claim 1 .
3. The vector of claim 2 , wherein said polynucleotide is operably linked to a control element.
4. An isolated cell comprising an exogenous polynucleotide, said exogenous polynucleotide comprising a nucleic acid sequence encoding a polypeptide having the amino acid sequence set forth in SEQ ID NO:23.
5. A plant comprising an exogenous polynucleotide, said exogenous polynucleotide comprising a control element operably linked to a nucleic acid sequence encoding a polypeptide having the amino acid sequence set forth in SEQ ID NO:23.
