Using Portulacaria afra, Peperomia species, Clusia species,                     and Xerosicyos danguyi, the study will examine the shift from                   C3-photosynthesis to CAM-cycling to CAM-idling or to CAM.                       Studies will be conducted at the metabolic, enzymatic, and                      genetic levels.  Detailed studies of CO2 exchange, acid                         flux, activities of key enzymes, properties of PEPC, PEPC                       protein levels and their rate of synthesis, as well as                          measurements of mRNA for PEPC will be conducted during the                      shift from C3 to CAM-cycling and ultimately to CAM.  The                        shifts will be induced by drought, as a funtion of season,                      and as a funciton of development.  Also to so be pursued is                     the hypothesis that abscisic acid (ABA) or other hormone is                     related to the shift, at least in response to drought.  By                      monitoring genes and their expression, it will be determined                    at what stage during the shift in photosynthetic metabolism                     that fixation of CO2 shifts from light to dark, when acid                       flux begins, at what stage mRNAs for key enzymes such as PEPC                   appear, and when the various enzymes and regulatory proteins                    appear.                                                                         %%%                                                                             The regulation of photosynthesis is one of the most                             important aspects for the understanding and control of plant                    growth and development.  It has direct relevance to the                         production of food, fiber, and chemicals.  In this project,                     photosynthetic regulation will be studied in plants which can                   shift their photosynthetic mode during water stress, in                         normal development and with seasonal change.
