Figure 5

Light-dependent P700 oxidation measurement and PSI activity in S. pistillata coral fragments. (a) PSI quantum yield (Y(I), acceptor and donor side limitations (Y(NA) and Y(ND), respectively) as a function of PPFD). (b) Relative electron transport rate through PSI (rETR-PSI) calculated as the product of Y(I) and PPFD. (c,d) Maximum P700 absorbance change in the presence of 20 µM DCMU at high light (Pm) in function of its chlorophyll a content (c) or in function of its skeleton thickness (d). A correlation factor (R2) obtained from a linear trendline is shown for (c) and (d). n = 13 for (a) and (b).
