Abstract
A method of enhancing inorganic carbon fixation by a photosynthetic organism. The method is effected by transforming cells of the photosynthetic organism with an expressible polynucleotide encoding a polypeptide having a bicarbonate transporter activity. Preferably, the polynucleotide further includes a plant promoter. Sequences and constructs for implementing the method are also described.
Claims23
A method of enhancing inorganic carbon fixation by a photosynthetic plant, the method comprising the step of transforming cells of the photosynthetic plant with an expressible polynucleotide encoding a polypeptide as set forth in SEQ ID NO:3, said polypeptide enhancing by at least 5% inorganic carbon fixation as compared to, otherwise similar, non-transformed cells of the photosynthetic plant, said polynucleotide comprises a plant promoter operable in expressing said polypeptide.
An isolated recombinant nucleic acid molecule for enhancing inorganic carbon fixation by a photosynthetic plant, the nucleic acid molecule comprising:
- (a) a polynucleotide encoding a polypeptide as set forth in SEQ ID NO:3;
- and
- (b) a plant promoter being upstream to said polynucleotide effective in expressing said polypeptide in a plant via nuclear transcription;
- with the provision that when said polypeptide is expressed in cells of the photosynthetic plant, at least 5% enhanced inorganic carbon fixation is measurable as compared to otherwise similar, non-transformed, cells of the photosynthetic plant.
