Article Snippet: story shade combine the effects of reductions in irradiance and changes in spectral quality.. We studied the seedling development of two Southeast Asian dipterocarp trees in response to differences in irradiance (photosynthetic photon flux density, PPFD) and spectral quality (red to far-red ratio, R:FR).. The two species, Hopea helferei and H. odorata, are taxonomically closely related but differ in their ecological requirements; H. helferei is more drought-tolerant and typically grows in more open habitats. Article Title: Differential effects of severe water stress on linear and cyclic electron fluxes through Photosystem I in spinach leaf discs in CO(2)-enriched air. Article Snippet: Linear and cyclic electron fluxes through Photosystem I in 1% CO2 were quantified in spinach leaf tissue under severe water stress.. Using actinic light with a peak at 697 nm for preferential light absorption by Photosystem I while also stimulating Photosystem II to improve redox poising, the cyclic electron flux after 60 s of illumination was a substantial proportion (33–44%) of the total electron flux through PSI at irradiances up to *1,070 lmol photons m s. At the maximum irradiance, the cyclic electron flux changed little with the progressive water loss from leaf tissue up to *60%; by contrast, the linear electron flux was approximately halved.. A reason for this differential effect of water stress on the capacity for cyclic and linear electron flow could be the increased crowding of soluble proteins in the stroma due to chloroplast shrinkage.

Article Snippet: Methyl viologen (MV) is a well-known electron mediator that works on the acceptor side of photosystem I.. We investigated the little-known, MV-induced inhibition of linear electron flow through photosystem II (PS II) in spinach-leaf discs.. Even a low [MV] decreased the (1) average, light-adapted photochemical efficiency of PS II traps, (2) oxidation state of the primary quinone acceptor QA in PS II during illumination, (3) photochemical efficiency of lightadapted open PS II traps, (4) fraction of absorbed light energy dissipated constitutively in a light-independent manner or as chlorophyll (Chl) a fluorescence emission, (5) Chl a fluorescence yield corresponding to dark-adapted open reactioncenter traps (Fo) and closed reaction-center traps (Fm), and (6) half-time for re-oxidation of QA in PS II after a singleturnover flash. Article Title: Quantification of cyclic electron flow around Photosystem I in spinach leaves during photosynthetic induction. Article Snippet: The variation of the rate of cyclic electron transport around Photosystem I (PS I) during photosynthetic induction was investigated by illuminating dark-adapted spinach leaf discs with red + far-red actinic light for a varied duration, followed by abruptly turning off the light.. The post-illumination re-reduction kinetics of P700, the oxidized form of the photoactive chlorophyll of the reaction centre of PS I (normalized to the total P700 content), was well described by the sum of three negative exponential terms.. The analysis gave a light-induced total electron flux from which the linear electron flux through PS II and PS I could be subtracted, yielding a cyclic electron flux. Article Title: Relationships between phytoplankton light absorption, pigment composition and size structure in offshore areas of the Mediterranean Sea Article Snippet: Phytoplankton absorption is mainly determined by pigment composition and packaging into the cell, in turn affected by pigment concentration and cell size and shape.. The variations of the chlorophyll-specific absorption coefficients at two selected wavelengths (443 nm and 675 nm) were analysed for offshore areas of the Mediterranean Sea (Alboran, Algerian, Tyrrhenian, Ionian Basins and Sardinia Channel) investigated in autumn 2006, 2007 and 2008.. The spatial distribution of Tchl a, accessory pigments, size structure and taxonomic composition of phytoplankton assemblages was diversified among the areas, characterized by higher contribution of photoprotective pigments in oligotrophic surface waters, while accessory chlorophylls increased in deeper layers and where microphytoplankton dominated. a ph(443) values decreased from the oligotrophic waters to the more mesotrophic ones where microphytoplankton prevailed, while for a ph(675) a small range of variation was observed.
