Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

Pest Management Science, EarlyView.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

Assimilation of solar‐induced fluorescence satellite observations in the European Centre for Medium‐Range Weather Forecasts integrated forecast system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This work demonstrates the potential of the assimilation of satellite solar‐induced fluorescence (SIF) retrievals at eight‐day and 0.1° resolutions in the integrated forecast system (IFS), developed at the European Centre for Medium‐Range Weather Forecasts (ECMWF), at global scale, to provide a more realistic representation of the vegetation temporal ...

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Non-photochemical quenching of fluorescence in cyanobacteria

Biochemistry (Moscow), 2007
The pathways of energy dissipation of excessive absorbed energy in cyanobacteria in comparison with that in higher plants are discussed. Two mechanisms of non-photochemical quenching in cyanobacteria are described. In one case this quenching occurs as light-induced decrease of the fluorescence yield of long-wavelength chlorophylls of the photosystem I ...

Activation of non-photochemical quenching in thylakoids and leaves

Planta, 1994
The mechanism of rapidly-relaxing non-photochemical quenching in two plant species,Chenopodium album L. andDigitalis purpurea L., that differ considerably in their capacity for such quenching has been investigated (Johnson G.N. et al. 1993, Plant Cell Environ. 16, 673–679).

Improving photosynthetic efficiency by modulating non-photochemical quenching

Trends in Plant Science, 2023
High light exposure rapidly activates non-photochemical quenching (NPQ), protecting plants from photooxidative damage. Contrarily, its relaxation upon transition to normal light occurs quite slowly, limiting photosynthetic efficiency. De Souza et al.

PsbS-Dependent Non-Photochemical Quenching

2014
Much of the research on the thermal dissipation of excess absorbed light, measured as non-photochemical quenching (NPQ) of chlorophyll fluorescence, has been focused on a major, rapidly induced and rapidly reversible component of fluorescence quenching termed energy-dependent quenching, feedback de-excitation, or qE.

How Protein Disorder Controls Non-Photochemical Fluorescence Quenching

2014
We discuss the de-excitation of electronically excited states of chlorophyll a, monitored via non-photochemical quenching (NPQ) of chlorophyll fluorescence, with respect to (i) involvement of the main light-harvesting complex of photosystem II (LHCII trimers) and (ii) a change in pigment properties following a change in the conformation of this protein

Excimer and non-photochemical quenching in LHCII

The Journal of Chemical Physics
The light-harvesting complex of photosystem II (LHCII) plays the dual roles of photosynthetic energy capture and dissipation, where the excitation energy in excess is dissipated safely via non-photochemical quenching (NPQ) to avoid photodamage. Chlorophyll excimer was recently reported to be an intrinsic photophysical intermediate in LHCII, which may ...

Is qE Always the Major Component of Non-photochemical Quenching?

2008
Non-photochemical quenching (NPQ) was measured in Col-0 and npq1 mutant plants of Arabidopsis thaliana exposed for 40 min to different light intensities (85, 175, 420, 750 and 1,200 μmol photons m−2 s−1). A light-induced increase of NPQ was measured in Col-0 as well as in npq1 plants but no significant differences were found between two genotypes.
