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 rice plant, said method comprising growing a rice plant cell comprising an exogenous nucleic acid, said exogenous nucleic acid comprising a regulatory region operably linked to a polynucleotide sequence,
wherein the polynucleotide sequence comprises a nucleotide sequence that encodes a polypeptide having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO: 209,
producing a rice plant from said rice plant cell, and
selecting the rice plant for having an increased panicle weight of at least 16.4% or an increased plant height of at least 5.66% as compared to the corresponding panicle weight or plant height of a control rice plant that does not comprise said exogenous nucleic acid.

2. The method of claim 1 , wherein said polypeptide comprises the amino acid sequence SEQ ID NO:209.

3. A transgenic rice plant or a progeny thereof, wherein the transgenic rice plant or progeny thereof comprises 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 having 95 percent or greater sequence identity to the amino acid sequence of SEQ ID NO: 209,
wherein the transgenic rice plant or progeny thereof is selected for having an increased panicle weight of at least 16.4% or an increased plant height of at least 5.66% as compared to the corresponding panicle weight or plant height of a control rice plant that does not comprise said exogenous nucleic acid.

4. The transgenic plant of claim 3 , wherein said polypeptide comprises the amino acid sequence SEQ ID NO: 209.

5. A seed product comprising embryonic tissue from the transgenic rice plant according to claim 4 , wherein the seed product comprises the exogenous nucleic acid.

6. The method of claim 1 , wherein the polynucleotide comprises the nucleotide sequence of SEQ ID NO:208.

7. The method of claim 1 , wherein the polypeptide has 97 percent or greater sequence identity to SEQ ID NO:209.

8. The transgenic rice plant of claim 3 , wherein the polynucleotide comprises the nucleotide sequence of SEQ ID NO:208.

9. The transgenic rice plant of claim 3 or a progeny thereof, wherein the transgenic rice plant or progeny thereof comprises the exogenous nucleic acid and wherein the polypeptide has 99 percent or greater sequence identity to SEQ ID NO:209.

10. The transgenic rice plant of claim 3 , wherein the polypeptide has 97 percent or greater sequence identity to SEQ ID NO:209.

11. A seed producing the transgenic rice plant of claim 3 , wherein the seed comprises the exogenous nucleic acid.
