Photoinhibition of photosynthesis on a coral reef
Photoinhibition of macroalgae in the epilithic algal community (EAC) of coral reefs was studied using chlorophyll fluorescence techniques at One Tree Island, Great Barrier Reef, Australia. F jFm (variable to maximum fluorescence darkened samples) of shallow macroalgae declined by 50% on fine summer and winte~ days, reco.vering i~ late afternoon. Within a species, thalh from low-hght habItats we...
متن کاملModeling Diurnal Variation of Whole-plant Photosynthesis of Greenhouse Roses
Whole-plant photosynthetic rate of rose (cv. Kardinal) was measured with an open system consisting of a computer-controlled data acquisition system and an infrared gas analyzer (IRGA). The system was used to monitor diurnal patterns of whole-plant gas exchange in response to environmental variables and a model to simulate this was constructed. A model for leaf photosynthesis was calibrated and ...
متن کاملCoral host cells acidify symbiotic algal microenvironment to promote photosynthesis.
Symbiotic dinoflagellate algae residing inside coral tissues supply the host with the majority of their energy requirements through the translocation of photosynthetically fixed carbon. The algae, in turn, rely on the host for the supply of inorganic carbon. Carbon must be concentrated as CO2 in order for photosynthesis to proceed, and here we show that the coral host plays an active role in th...
متن کاملThe relationship between diurnal variations in intraocular pressure measurements and central corneal thickness and corneal hysteresis.
PURPOSE To examine the relationship between office-hour changes in IOP, measured with the Goldmann applanation tonometer (GAT) and dynamic contour tonometer (DCT), and the corneal characteristics central corneal thickness (CCT) and corneal hysteresis (CH). METHODS Sixty-two eyes of 62 untreated normal subjects and patients with untreated glaucoma had IOP measurements performed with the GAT (m...
متن کاملProteomics analysis reveals a dynamic diurnal pattern of photosynthesis-related pathways in maize leaves
Plant leaves exhibit differentiated patterns of photosynthesis rates under diurnal light regulation. Maize leaves show a single-peak pattern without photoinhibition at midday when the light intensity is maximized. This mechanism contributes to highly efficient photosynthesis in maize leaves. To understand the molecular basis of this process, an isobaric tag for relative and absolute quantitatio...
