Abstract
A new procedure is reported for high-yield isolation of guard cell protoplasts from Vicia faba L. Delayed light emission and P(700) content plus absorption and fluorescence emission spectra of these protoplast extracts are reported. It is concluded that both photosystems are present. The presence of photosystem II and the absence of the reductive-step enzyme of the Calvin-Benson Cycle (Outlaw WH Jr, J Manchester, CH DiCamelli, DD Randall, B Rapp, GM Veith 1979 Proc Natl Acad Sci USA 76: 6371-6375) in a cell has no precedent in the literature. It is speculated that noncyclic photosynthetic electron flow is an environmental sensor which causes stomata to remain open in light.Entities:
