Reconstructing the origin of oxygenic photosynthesis: do assembly and photoactivation recapitulate evolution?

Frontiers in Plant Science, 2016
Due to the great abundance of genomes and protein structures that today span a broad diversity of organisms, now more than ever before, it is possible to reconstruct the molecular evolution of protein complexes at an incredible level of detail.

Monitoring photosynthesis in individual cells of Synechocytis sp. PCC 6803 on a picosecond timescale

, 2010
Picosecond fluorescence kinetics of wild-type (WT) and mutant cells of Synechocystis sp. PCC 6803, were studied at the ensemble level with a streak-camera and at the cell level using fluorescence-lifetime-imaging microscopy (FLIM).

Cytoplasmic N-Terminal Protein Acetylation Is Required for Efficient Photosynthesis in Arabidopsis [PDF]

, 2003
The Arabidopsis atmak3-1 mutant was identified on the basis of a decreased effective quantum yield of photosystem II. In atmak3-1, the synthesis of the plastome-encoded photosystem II core proteins D1 and CP47 is affected, resulting in a decrease in the ...

Cyanobacterial Acclimation to Photosystem I or Photosystem II Light [PDF]

Plant Physiology, 1986
The organization and function of the photochemical apparatus of Synechococcus 6301 was investigated in cells grown under yellow and red light regimes. Broadband yellow illumination is absorbed preferentially by the phycobilisome (PBS) whereas red light is absorbed primarily by the chlorophyll (Chl) pigment beds.

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

Applications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Photosystem II function under extreme low light and low temperatures; polar vs. temperate phytoplankton

Frontiers in Photobiology
Polar phytoplankton achieve slow, but ecologically significant, productivity under exceptionally low light, where the sequential arrivals of photons at Photosystem II complexes are widely spaced in time.

Use of chlorophyll fluorescence and P700 absorbance to rapidly detect glyphosate resistance in goosegrass (Eleusine indica)

Journal of Integrative Agriculture, 2015
The rapid detection of glyphosate resistance in goosegrass (Eleusine indica) will enhance our ability to respond to new resistant populations of this major weed.

Special issue in honour of Prof. Reto J. Strasser - Influence of Cuscuta campestris Yunck. on the photosynthetic activity of Ipomoea tricolor Cav. - in vivo chlorophyll a fluorescence assessment

Photosynthetica, 2020
Cuscuta campestris Yunck. is a parasitic plant, acquiring nutrients from the hosts. Although a generalist, its hosts differ in their susceptibility. Ipomoea tricolor Cav. is a semi-compatible host - C.

Hydrogen Migration Enhances Proton‐Coupled Electron Transfer in an S‐Scheme Heterojunction for High‐Efficiency Photocatalysis

Carbon Energy, EarlyView.
Precisely directed built‐in electric field in an S‐scheme heterojunction synergizes photogenerated charge separation with interfacial proton migration, thus co‐localizing electrons and protons on the NOH surface and boosting proton‐coupled electron transfer kinetics in the rate‐determining hydrogen release step. ABSTRACT The kinetic bottleneck in solar‐

Effects of spine-shading on aspects of photosynthesis for three cactus species

Botan‪ical Sciences, 2016
We evaluated the effect of spine removal on three cactus species varying in spine-shading of stems. Turbinicarpus schmiedickeanus showed the greater spine shading (c. 61 %), followed by Mammillaria zephyranthoides (43 %), and Echinocactus platyacanthus (
