ENHANCING PHOTOSYNTHETIC RATES, ABIOTIC STRESS TOLERANCE AND BIOMASS YIELD BY EXPRESSING C4 PLANT FERREDOXINS IN C3 PLANTS

摘要

The invention include systems, methods, and compositions related to the enhancement of photosynthetic electron transfer rates, abiotic stress tolerance, C0₂ fixation rates, and increases in yield/biomass in plants. These methods and associated transgenic plants encompass the expression, or overexpression, of one or more genes that improve photosynthetic electron transfer rates, abiotic stress tolerance, C0₂ fixation rates, and yield/biomass in plants. Such enhanced plant characteristics may be achieved through the expression, or overexpression of select photosynthetic ferredoxin proteins in a plant or plant cell. In certain embodiments, such enhanced plant characteristics may be achieved through the expression, or overexpression, of one or more photosynthetic ferredoxin proteins from a C4 plant in a C3 plant or plant cell.
