Plants having enhanced yield-related traits and a method for making the same

A method for making a plant having enhanced nitrogen use efficiency relative to a control plant, comprising

• (a) transforming a plant with a construct comprising:
• (i) a nucleic acid encoding a Nitrite Reductase (NITR) polypeptide, wherein said NITR polypeptide comprises the amino acid sequence of SEQ ID NO:
• 2 or an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
• 2;
• (ii) one or more control sequences capable of driving expression of the nucleic acid sequence of (i);
• and optionally
• (iii) a transcription termination sequence;
• and
• (b) selecting a plant having enhanced nitrogen use efficiency.

A method for the production of a transgenic plant having enhanced nitrogen use efficiency relative to a control plant, comprising:

• (i) introducing and expressing in a plant a nucleic acid encoding a Nitrite Reductase (NITR) polypeptide, wherein said NITR polypeptide comprises the amino acid sequence of SEQ ID NO:
• 2 or an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
• 2;
• (ii) cultivating the plant under conditions promoting plant growth and development;
• and
• (iii) selecting a plant having enhanced nitrogen use efficiency.
