Multiple functions of photosystem II.
Indian journal of biochemistry & biophysics, 2000 The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed. In addition to this most important activity, PSII has additional functions, especially in the regulation of (light) energy distribution.

Water oxidation in photosystem II [PDF]
Photosynthesis Research, 2019 Biological water oxidation, performed by a single enzyme, photosystem II, is a central research topic not only in understanding the photosynthetic apparatus but also for the development of water splitting catalysts for technological applications.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Reduced model of photosystem II and its use to evaluate the photosynthetic apparatus characteristics according to the fluorescence induction curves [PDF]
Компьютерные исследования и моделирование, 2012 The approach for the analysis of some large-scale biological systems, on the base of quasiequilibrium stages is proposed. The approach allows us to reduce the detailed large-scaled models and obtain the simplified model with an analytical solution.

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors
Advanced Materials, EarlyView.A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology
Advanced Materials Technologies, EarlyView.The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

Chlorophyll Fluorescence Measurements in Arabidopsis Wild-type and Photosystem II Mutant Leaves
Bio-Protocol, 2015 Chlorophyll fluorescence measurement is a widely used technique to determine photosynthetic performance. Light energy absorbed by a chlorophyll molecule can be dissipated by driving photochemical energy conversion, as heat in non-photochemical quenching ...

Molecular Evolution of Far-Red Light-Acclimated Photosystem II
Microorganisms, 2022 Cyanobacteria are major contributors to global carbon fixation and primarily use visible light (400−700 nm) to drive oxygenic photosynthesis. When shifted into environments where visible light is attenuated, a small, but highly diverse and widespread ...

Photoinactivation of Photosystem II in leaves
Photosynthesis Research, 2005 Photoinactivation of Photosystem II (PS II), the light-induced loss of ability to evolve oxygen, inevitably occurs under any light environment in nature, counteracted by repair. Under certain conditions, the extent of photoinactivation of PS II depends on the photon exposure (light dosage, x), rather than the irradiance or duration of illumination per ...
