PLANT CO2 SENSORS, NUCLEIC ACIDS ENCODING THEM, AND METHODS FOR MAKING AND USING THEM

摘要

The invention provides compositions and methods for manipulating the exchange of water and/or carbon dioxide (CO₂) through plant stomata by controlling CO₂ sensor genes. The invention provides compositions and methods for enhancing or optimizing biomass accumulation in a plant. The invention provides compositions and methods for for opening or closing a stomatal pore on a guard cell in the epidermis of a plant. The invention provides compositions and methods for increasing or decreasing oxygenation efficiency and/or carbon fixation in a guard cell in the epidermis of a plant by manipulating expression of a ribulose- 1,5-bisphosphate carboxylase/oxygenase. The invention provides promoters for regulating expression of a nucleic acid in a plant guard cell.
