Plant CO2 sensors, nucleic acids encoding them, and methods for making and using them

A set of recombinant or synthetic antisense nucleic acids comprising:

• (a) (i) a first nucleic acid complementary to or capable of hybridizing under stringent conditions to a sequence comprising a nucleic acid sequence encoding an amino acid sequence having at least about 95%, 96%, 97%, 98%, or 99%, or more or complete sequence identity to SEQ ID NO:3, or functional fragments thereof, wherein the first nucleic acid sequence or functional fragment nucleic acid sequence encodes a polypeptide with a β-carbonic anhydrase (carbonate dehydratase) activity, and
• (ii) a second nucleic acid complementary to or capable of hybridizing under stringent conditions to a sequence comprising a nucleic acid sequence encoding an amino acid sequence having at least about 95%, 96%, 97%, 98%, or 99%, or more or complete sequence identity to SEQ ID NO:9 or functional fragments thereof, wherein the second nucleic acid or functional fragment encodes a polypeptide with a β-carbonic anhydrase (carbonate dehydratase) activity, or
• (b) (i) a first nucleic acid having at least about 95%, 96%, 97%, 98%, or 99%, or more or complete sequence identity to SEQ ID NO:1 over a region of at least about 50, 75, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150 or more residues, or over the full length of a protein coding sequence (transcript) or gene, and
• (ii) a second nucleic acid having at least about 95%, 96%, 97%, 98%, or 99%, or more or complete sequence identity to SEQ ID NO:7 over a region of at least about 50, 75, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150 or more residues, or over the full length of a protein coding sequence (transcript) or gene.
