Nucleotide sequences and corresponding polypeptides conferring modulated plant growth rate and biomass in plants

A method for promoting increased biomass in a plant grown in low nitrate conditions, said method comprising:

• (a) transforming a plant cell with a nucleic acid molecule comprising a nucleotide sequence encoding an amino acid sequence that is at least 95% identical to the sequence set forth in SEQ ID NO:
• 95;
• (b) regenerating from said plant cell a transformed plant in which said nucleic acid molecule is overexpressed;
• and
• (c) selecting from a plurality of said transformed plants a transformed plant having an increased biomass as compared to a plant that has not been transformed with said nucleotide sequence and is grown under the same conditions.

A method for increasing biomass of a plant grown in low nitrate conditions, said method comprising:

• a) introducing into a plant cell a vector construct comprising
• a first nucleic acid molecule that is a regulatory sequence which causes transcription in a plant;
• and
• a second nucleic acid molecule encoding an amino acid sequence that is at least 95% identical to the sequence set forth in SEQ ID NO:
• 95, wherein said first and second nucleic acid molecules are operably linked;
• b) regenerating from said plant cell a transformed plant in which said second nucleic acid molecule is overexpressed;
• and
• c) selecting from a plurality of said transformed plants a transformed plant having increased biomass when grown in low nitrate conditions as compared to a control plant that does not comprise said overexpressed nucleic acid and is grown under the same conditions.

A method of modulating architecture of a plant grown in low nitrate conditions, said method comprising:

• (a) introducing into a plant cell an isolated nucleic acid molecule comprising a nucleotide sequence that encodes an amino acid sequence that is at least 95% identical to the amino acid sequence set forth in SEQ ID NO:
• 95;
• (b) regenerating from said plant cell a transformed plant in which said nucleic acid molecule is overexpressed;
• and
• (c) selecting from a plurality of said transformed plants a transformed plant having modulated plant architecture when grown in low nitrate conditions as compared to a control plant grown under the same conditions.
