The photosystem I assembly apparatus consisting of Ycf3–Y3IP1 and Ycf4 modules
Nature Communications, 2018 In oxygenic photosynthesis, light energy is converted into redox energy by two photosystems (PSI and PSII). PSI forms one of the largest multiprotein complexes in thylakoid membranes consisting of a core complex, peripheral light-harvesting complexes ...

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2008 Diatoms occupy a key position as a primary producer in the global aquatic ecosystem. We developed methods to isolate highly intact thylakoid membranes and the photosystem I (PS I) complex from a marine centric diatom, Chaetoceros gracilis. The PS I reaction center (RC) was purified as a super complex with light-harvesting fucoxanthin-chlorophyll (Chl ...

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2007 A photosystem I (PSI)-fucoxanthin chlorophyll protein (FCP) complex with a chlorophyll a/P700 ratio of approximately 200:1 was isolated from the diatom Phaeodactylum tricornutum. Spectroscopic analysis proved that the more tightly bound FCP functions as a light-harvesting complex, actively transferring light energy from its accessory pigments ...

Expression profiles of sugarcane under drought conditions: Variation in gene regulation
Genetics and Molecular Biology, 2015 Drought is a major factor in decreased sugarcane productivity because of the resulting morphophysiological effects that it causes. Gene expression studies that have examined the influence of water stress in sugarcane have yielded divergent results ...

Assembly of the precursor and processed light-harvesting chlorophyll a/b protein of Lemna into the light-harvesting complex II of barley etiochloroplasts. [PDF]
, 1986 When the in vitro synthesized precursor of a light-harvesting chlorophyll a/b binding protein (LHCP) from Lemna gibba is imported into barley etiochloroplasts, it is processed to a single form.

Covalently Binding the Photosystem I to Carbon Nanotubes
, 2009 We present a chemical route to covalently couple the photosystem I (PS I) to carbon nanotubes (CNTs). Small linker molecules are used to connect the PS I to the CNTs.

Inhomogeneous energy transfer dynamics from iron-stress-induced protein A to photosystem I
Frontiers in Plant ScienceCyanobacteria respond to iron limitation by producing the pigment-protein complex IsiA, forming rings associated with photosystem I (PSI). Initially considered a chlorophyll-storage protein, IsiA is known to act as an auxiliary light-harvesting antenna ...

Modeling of Transient Absorption Spectra in Exciton Charge-Transfer Systems
, 2017 Time-resolved spectroscopy provides the main tool for analyzing the dynamics of excitonic energy transfer in light-harvesting complexes. To infer time-scales and effective coupling parameters from experimental data requires to develop numerical exact ...
