Chlorophyll (Chl) a is found in all oxygenic photosynthetic organisms. Manning and Strain 1943 ([ 1 ][1]) others 2 ][2]–[ 4 ][3]) reported Chl d (3-desvinyl-3-formyl a) as the second pigment several species of marine macrophytic red algae, it now considered genuine
Changes in the temperature dependence of photosynthetic rate depending on growth were investigated for a temperate evergreen tree, Quercus myrsinaefolia . Plants grown at 250 μ mol quanta m –2 s –1 under two conditions, 15 and 30 °C. The optimal that maximizes light‐saturated photosynthesis 350 L CO 2 was found to be 20–25 30–35 °C leaves °C, respectively. We focused processes, carboxylation regeneration ribulose‐1,5‐bisphosphate (RuBP), which potentially limit rates. Because former process...
This study investigated the potential local CH4 sink in various plant parts as a boundary environment of emission and consumption. By comparing consumption activities cultures inoculated with from 39 species, we observed significantly higher associated aquatic plants than other emergent such woody leaves, macrophytic marine algae, sea grass. In situ activity by methanotrophs different species was range 3.7-37 μmol·h(-1)·g(-1) dry weight, which ca 5.7-370-fold epiphytic submerged plants. The...
Photosystem I (PSI) is a multi-subunit pigment-protein complex that functions in light-harvesting and photochemical charge-separation reactions, followed by reduction of NADP to NADPH required for CO 2 fixation photosynthetic organisms. PSI from different organisms has variety chlorophylls (Chls), some which are at lower-energy levels than its reaction center P700, special pair Chls, called low-energy Chls. However, the sites Chls still under debate. Here, we solved 2.04-Å resolution...
Regulation of electron transport composition was studied with Synechocystis (Aphanocapsa) PCC 6714 grown under various trophic conditions. Photosystem (PS) composition, PS I/IIratio, used as the index for system. Special attention paid to relationship between changes in I/II ratio and features transport. Results indicated that (1) change system is induced not only by light conditions but also influx efflux. (2) The occurs so relieve imbalance efflux, caused transport, (3) redox state...

Summary In Catharanthus roseus , monoterpenoid indole alkaloids (MIAs) are produced through the cooperation of four cell types, with final products accumulating in specialized cells known as idioblasts and laticifers. To explore relationship between cellular differentiation type‐specific MIA metabolism, we analyzed expression biosynthesis germinating seeds. Embryos from immature mature seeds were observed via stereomicroscopy, fluorescence microscopy, electron microscopy. Time‐series iridoid...
Changes in photosystem stoichiometry response to shift of environments for cell growth other than light regime were studied with the cyanophyte Synechocystis PCC 6714 relation change induced by light-quality shift. Following two environment-shifts examined: molecular form inorganic carbon source photosynthesis from CO2 HCO3− (CO2 stress) and increase salinity medium NaCl (0.5 M) (Na+ stress). Both Na+ stresses PSI abundance resulting a higher PSI/PSII stoichiometry. stress was found elevate...

Energy dissipation is crucial for land and shallow-water plants exposed to direct sunlight. Almost all green dissipate excess excitation energy protect the photosystem reaction centers, II (PSII) I (PSI), continue grow under strong light. In our previous work, we reported that about half of centers form a PSI–PSII megacomplex in Arabidopsis thaliana, was transferred from PSII PSI fast. However, physiological function structure remained unclear. Here, suggest high-light adaptable sun-plants...

Whereas the oxygen isotope ratio of coral skeleton is used for reconstruction past information on seawater, carbon considered a proxy physiological processes, principally photosynthesis and respiration. However, fractionation isotopes in biogenic carbonate such as still unclear. We conducted long‐term culture experiment Porites spp. corals at different light dosages (light intensity, 100, 300, or 500 μ mol m −2 s −1 ; daily period, 10 12 h) 25 ± 0.6°C to examine contribution photosynthetic...
The identification of protein complexes is important for the understanding structure and function regulation cellular processes. We used blue-native PAGE tandem mass spectrometry to identify systematically, built a web database, co-migration database (PCoM-DB, http://pcomdb.lowtem.hokudai.ac.jp/proteins/top), provide prediction tools complexes. PCoM-DB provides migration profiles any given interest, allows users compare them with other proteins, showing oligomeric states proteins thus...
Carotenoid composition is very diverse in Rhodophyta. In this study, we investigated whether variation related to the phylogeny of group. Rhodophyta consists seven classes, and they can be divided into two groups on basis their morphology. The unicellular group (Cyanidiophyceae, Porphyridiophyceae, Rhodellophyceae, Stylonematophyceae) contained only β-carotene zeaxanthin, "ZEA-type carotenoids." contrast, within macrophytic (Bangiophyceae, Compsopogonophyceae, Florideophyceae),...
