Abstract

Methods and materials for modulating biomass levels in plants are disclosed. For example, nucleic acids encoding biomass-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased biomass levels and plant products produced from plants having increased biomass levels.

First claim

What is claimed is:

1 . 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 the nucleotide sequence encodes a polypeptide comprising an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:117, producing a plant from said plant cell, wherein the plant expresses the polypeptide, and selecting the plant for having an increased plant biomass of at least 60% as compared to the corresponding plant biomass an of a control plant that does not comprise said exogenous nucleic acid.

2 . The method of claim 1 , wherein said polypeptide comprises the amino acid sequence of SEQ ID NO: 117.

3 . A transgenic plant comprising an exogenous nucleic acid, said exogenous nucleic acid comprising a regulatory region operably linked to a nucleotide sequence, wherein the nucleotide sequence encodes a polypeptide comprising an amino acid sequence having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:117 that is expressed in the plant, wherein the plant is selected for having an increased plant biomass of at least 60% as compared to the corresponding plant biomass of a control plant that does not comprise said exogenous nucleic acid.

4 . A progeny of the transgenic plant of claim 3 , wherein the progeny comprises the exogenous nucleic acid and exhibits the increased plant biomass of the transgenic plant.

5 . The transgenic plant of claim 3 , wherein said plant is a member of a species selected from the group consisting of switchgrass, sorghum , sudangrass, miscanthus , energycane, poplar, corn, soybean, canola, wheat, cotton, rice, sunflower, alfalfa, sugarbeet, and pearl millet.

6 . The transgenic plant of claim 3 , wherein said polypeptide comprises the amino acid sequence of SEQ ID NO:117.

7 . A seed product comprising embryonic tissue from the transgenic plant according to claim 3 or from a progeny thereof, wherein the seed product comprises the exogenous nucleic acid.

8 . The method of claim 1 , wherein the polynucleotide comprises the nucleotide sequence of SEQ ID NO:116.

9 . The method of claim 1 , wherein the polypeptide has 97 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:117.

10 . The progeny of claim 4 , wherein the polynucleotide comprises the nucleotide sequence of SEQ ID NO:116.

11 . The progeny of claim 4 , wherein the polypeptide has 97 percent or greater sequence identity to the amino acid sequence of SEQ ID NO:117.

12 . A seed produced by the progeny of claim 4 , wherein the seed comprises the exogenous nucleic acid.
