Patent ID: 8426677

Claim:
A method of generating a transgenic plant having one or more features selected from the group consisting of reduced height, increased tillering number, more biomass, a stronger and thicker stem, a stronger root system, more leaves, stable increase of yields and/or seed production, and enhanced stress tolerance, than a plant of substantially the same genetic background grown under the same conditions, the method comprising: (a) transforming a cell of the plant of substantially the same genetic background with a nucleic acid molecule to obtain a recombinant plant cell; (b) generating a transgenic plant from the recombinant plant cell, wherein the transgenic plant recombinantly expresses a polypeptide selected from the group consisting of: (1) a polypeptide having an amino acid sequence that is at least about 80% identical to SEQ ID NO:2, wherein the amino acid sequence has a domain that is at least 80% identical to SEQ ID NO:70; (2) a polypeptide having an amino acid sequence that is at least about 80% identical to SEQ ID NO:4, wherein the amino acid sequence has a domain that is at least 80% identical to SEQ ID NO:71; (3) a polypeptide having an amino acid sequence that is at least about 80% identical to SEQ ID NO:10 or at least about 80% identical to SEQ ID NO:12, wherein the amino acid sequence has a domain that is at least 80% identical to SEQ ID NO:74; and (4) a mutant class C20 GA2ox having at least one mutation in domain III of class C20 GA2ox, the mutant C20 GA2ox having a reduced enzymatic activity to hydroxylate a class C20-GA precursor compared with an otherwise identical class C20 GA2ox that does not comprise the at least one mutation, and the domain III comprising the amino acid sequence of SEQ ID NO:17.
