PLANT CO 2 SENSORS, NUCLEIC ACIDS ENCODING THEM, AND METHODS FOR MAKING AND USING Abstract Figure 17 The invention provides compositions and methods for manipulating the exchange of water and/or carbon dioxide (C0 2) through plant stomata by controlling CO 2 sensor genes. The invention provides compositions and methods for enhancing or optimizing biomass accumulation in a plant. The invention provides compositions and methods 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.
