The phycobilisome (PBS) is a major light-harvesting complex in cyanobacteria and red algae. To obtain the detailed structure of the hemidiscoidal PBS core composed of allophycocyanin (APC) and minor polypeptide components, we analyzed all n...
Photorespiration provides the chance of cyclic electron flow to operate for the redox-regulation of P700 in photosynthetic electron transport system of sunflower leaves [0.03%]
光呼吸为能量循环流动调节P700+/P700在向日葵叶片中光合电子传递系统中的氧化还原态提供机会

Daisuke Takagi et al.
To elucidate the molecular mechanism to oxidize the reaction center chlorophyll, P700, in PSI, we researched the effects of partial pressure of O2 (pO2) on photosynthetic characteristic parameters in sunflower (Helianthus annuus L.) leaves....
Molecular studies on structural changes and oligomerisation of violaxanthin de-epoxidase associated with the pH-dependent activation [0.03%]
与pH值依赖激活相关光保护色素脱环氧酶结构变化及寡聚化的分子研究

Erik Ingmar Hallin et al.
Violaxanthin de-epoxidase (VDE) is a conditionally soluble enzyme located in the thylakoid lumen and catalyses the conversion of violaxanthin to antheraxanthin and zeaxanthin, which are located in the thylakoid membrane. These reactions occ...
The effect of lanthanides on photosynthesis, growth, and chlorophyll profile of the green alga Desmodesmus quadricauda [0.03%]
镧系元素对绿藻Desmodesmus quadricauda光合作用、生长和叶绿素谱型的影响

Tomáš Řezanka et al.
Lanthanides (La, Gd, Nd, Ce) accumulated in the green alga Desmodesmus quadricauda but their intracellular localizations were distinctly different: lanthanum and gadolinium were localized in cytoplasm, while neodymium and cerium were in the...
In photosynthesis, oxygen comes from water: from a 1787 book for women by Monsieur De Fourcroy [0.03%]
光合作用中的氧气来自水：取材于1787年一本面向女性的读物（富克罗先生著）
Pierre Joliot,Antony R Crofts,Lars Olof Björn et al.
Pierre Joliot et al.
It is now well established that the source of oxygen in photosynthesis is water. The earliest suggestion previously known to us had come from René Bernard Wurmser (1930). Here, we highlight an earlier report by Monsieur De Fourcroy (1787),...
The efficiency of non-photochemical fluorescence quenching by cation radicals in photosystem II reaction centers [0.03%]

In the evolution of different cyanobacteria performing oxygenic photosynthesis, the core complexes of the two photosystems were highly conserved. However, cyanobacteria exhibit significant diversification in their light-harvesting complexes...
Crystal structure analysis of C-phycoerythrin from marine cyanobacterium Phormidium sp. A09DM [0.03%]
