Abstract

Several photosynthetic parameters were examined in the different tissue layers of leaves from the recently characterized crassulacean acid metabolism/C4 intermediate plant, Peperomia camptotricha (Nishio and Ting, 1987). Light appears to control the development of certain photosynthetic characteristics within the tissue layers, while factors otherthan light seem to dictate others. Analysis of the chlorophyll content (including P700) and chlorophyll-proteins indicated that more light harvesting chlorophylls were associated with reaction centers in the tissues that were shaded by overlying tissue. Electron transport activity and chlorophyll-protein analysis indicated that the ratio of photosystem I to photosystem II in the spongy mesophyll (the abaxial tissue type and hence most shaded) was elevated relative to the overlying chlorophyll-rich median palisade mesophyll. The elevated photosystem I relative to photosystem II in the spongy mesophyll of Peperomia camptotricha may be related to C4 metabolism and an increased requirement for ATP.
