Nannochloropsis is an eukaryotic alga of the phylum Heterokonta, originating from a secondary endosymbiotic event. In this work, we investigated how the photosynthetic apparatus responds to growth in different light regimes in Nannochlorops...
Essential role of the PSI-LHCII supercomplex in photosystem acclimation to light and/or heat conditions by state transitions [0.03%]
PSI-LHCII 超复合物在光和/或热条件下通过状态转换进行光系统适应中的关键作用
Yoko Marutani,Yasuo Yamauchi,Mari Higashiyama et al.
Yoko Marutani et al.
Light and temperature affect state transitions through changes in the plastoquinone (PQ) redox state in photosynthetic organisms. We demonstrated that light and/or heat treatment induced preferential photosystem (PS) I excitation by binding...

Julie E Chaves et al.
Heterologous production of isoprene (C5H8) hydrocarbons in cyanobacteria, emanating from sunlight, CO2, and water, is now attracting increasing attention. The concept entails application of an isoprene synthase transgene from terrestrial pl...
The plastoquinol-plastoquinone exchange mechanism in photosystem II: insight from molecular dynamics simulations [0.03%]
基于分子动力学模拟的光系统II中plastoquinol和plastoquinone交换机制的研究
Veranika Zobnina,Maya D Lambreva,Giuseppina Rea et al.
Veranika Zobnina et al.
In the photosystem II (PSII) of oxygenic photosynthetic organisms, the reaction center (RC) core mediates the light-induced electron transfer leading to water splitting and production of reduced plastoquinone molecules. The reduction of pla...
