SUPPRESSION OF TLA2-CpFTSY GENE EXPRESSION FOR IMPROVED SOLAR ENERGY CONVERSION EFFICIENCY AND PHOTOSYNTHETIC PRODUCTIVITY IN ALGAE

摘要

The invention provides method and compositions to minimize the chlorophyll antenna size of photosynthesis by decreasing TLA2 gene expression, thereby improving solar conversion efficiencies and photosynthetic productivity in green microalgae, under bright sunlight conditions.

主权项

1. A method of decreasing chlorophyll antenna size in a strain of green microalgae, the method comprising:
inhibiting expression of a Tla2 nucleic acid in the green algae strain by introducing into the green microalgae strain an expression cassette comprising a promoter operably linked to a polynucleotide that suppresses expression of Tla2; and selecting algae with decreased chlorophyll antenna size compared to green algae in which the expression cassette has not been introduced.
