Plants with enhanced photosynthesis and methods of manufacture thereof

A method of producing a transgenic plant having enhanced photosynthesis, the method comprising:

• transforming a plant cell with a recombinant polynucleotide comprising a nucleic acid sequence encoding an algal CCP1 or CCP2 polypeptide, comprising an amino acid sequence that is at least 75% identical to SEQ ID NO:
• 6, operatively linked to a plant-expressible promoter, wherein the nucleic acid sequence encoding the algal CCP1 or CCP2 polypeptide is further operatively linked to a transcription terminator;
• growing a transgenic plant from the plant cell until the transgenic plant produces seed;
• and
• selecting seeds from the transgenic plant in which the transgenic plant has:
• (i) a CO2 assimilation rate higher than a plant of the same species not transformed with the recombinant DNA construct;
• and
• (ii) a reduced transpiration rate lower than a plant of the same species not transformed with the recombinant DNA construct.
