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

A method for the production of a transgenic plant having increased seed yield relative to a control plant, comprising:

• (a) introducing and expressing in a plant a nucleic acid encoding a CLC-like polypeptide wherein said nucleic acid is selected from the group consisting of:
• (i) a nucleic acid comprising the nucleotide sequence of SEQ ID NO:
• 1;
• (ii) a nucleic acid encoding a polypeptide comprising the amino acid sequence of SEQ ID NO:
• 2;
• and
• (iii) a nucleic acid encoding a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
• 2;
• (b) cultivating the plant under conditions promoting plant growth and development;
• and
• (c) selecting for a plant having increased seed yield relative to a control plant.

A method for increasing biomass and/or seed yield in a plant relative to a control plant, comprising:

• (a) introducing and expressing in a plant a nucleic acid encoding a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
• 2;
• and
• (b) selecting for a plant having increased biomass and/or seed yield relative to a control plant by measuring and comparing biomass and/or one or more seed-related parameters selected from the group consisting of total weight of seeds, number of filled seed, seed fill rate, harvest index, and Thousand Kernel Weight (TKW) of said plant and said control plant.
