Abstract
Methods and compositions for improving photosynthesis by eliminating a sustained photoprotective mechanism by mutating or silencing the Chloroplastic Lipocalin (CHL) gene whereby photosynthesis of the plants increases. The sustained photoprotective mechanism negatively regulated by the Suppressor of Quenching 1 protein involves the chloroplastic lipocalin and occurs in the peripheral antenna of photosystem II.
Claims9
A method for improving photosynthesis in a plant cell or plant, comprising the reducing the expression of a Chloroplastic Lipocalin (CHL) gene in a plant cell or plant whereby the plant cell or plant, when cultured or grown under conditions suitable for photosynthesis, increases photosynthesis within the plant cell or plant.
A method for improving photosynthesis in a plant, comprising the steps of eliminating a sustained photoprotective mechanism in a plant by mutating or silencing the Chloroplastic Lipocalin (CHL) gene whereby photosynthesis of the plants increases.
A polynucleotide encoding a mutant CHL protein, wherein the mutant CHL protein has reduced or no biological activity.
