Dynamics of photosynthetic membrane composition and function

Twenty-two common British angiosperms were examined for their ability to acclimate photosynthetically to sun and shade conditions Plants were grown under low irradiance, far-red enriched light (50 μmol m−2 s−1), selected to mimic as closely as possible natural canopy shade, and moderately high light of insufficient irradiance to induce photoinhibitory or photoprotective responses (300 μmol m−2 s−1) Light-and CO2-saturated photosynthetic rates of oxygen evolution (Pmax) and chlorophyll content were measured Large variation was found in both parameters, and two ‘strategies’ for long-term acclimation were identified: firstly a change in chlorophyll per unit leaf area which was found to correlate positively with photosynthetic capacity, and secondly changes in chlorophyll alb ratio and Pmax, indicative of alterations at the chloroplast level, which were not associated with a change in chlorophyll content per unit leaf area Combinations of these two strategies may occur, giving rise to the observed diversity in photosynthetic acclimation The extent and nature of photosynthetic acclimation were compared with an index of shade association, calculated from the association each species has with woodland It was found that the greatest flexibility for change at the chloroplast level was found in those species possessing an intermediate shade association, whilst acclimation in ‘sun’ species proceeded by a change in chlorophyll content; obligate shade species showed little capacity for acclimation at either the chloroplast or leaf level A framework for explaining the variation between plant species in leaf-level photosynthetic capacity, in relation to the natural light environment, is presented This is the first time the potential for light acclimation of photosynthesis in different plant species has been satisfactorily linked to habitat distribution
