Analysis of initial chlorophyll fluorescence induction kinetics in chloroplasts in terms of rate constants of donor side quenching release and electron trapping in photosystem II [PDF]

, 2008
The fluorescence induction F(t) of dark-adapted chloroplasts has been studied in multi-turnover 1 s light flashes (MTFs). A theoretical expression for the initial fluorescence rise is derived from a set of rate equations that describes the sequence of ...

In vivo label-free mapping of the effect of a photosystem II inhibiting herbicide in plants using chlorophyll fluorescence lifetime

Plant Methods, 2017
Background In order to better understand and improve the mode of action of agrochemicals, it is useful to be able to visualize their uptake and distribution in vivo, non-invasively and, ideally, in the field.

Bay Leaf Extract-Based Near-Infrared Fluorescent Probe for Tissue and Cellular Imaging

Journal of Imaging, 2021
The development of fluorescence dyes for near-infrared (NIR) fluorescence imaging has been a significant interest for deep tissue imaging. Among many imaging fluoroprobes, indocyanine green (ICG) and its analogues have been used in oncology and other ...

Chlorophyll Fluorescence Imaging of the Chlorophyll Fluorescence Induction Phenomenon for Plant Health Monitoring

Environment Control in Biology, 2009
Chlorophyll fluorescence imaging is useful as a non-destructive method for evaluating photosynthetic function of plants. A dynamic change in chlorophyll fluorescence intensity, known as the chlorophyll fluorescence induction phenomenon, can be observed by illuminating a dark-adapted green leaf with a stable intensity excitation light.

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

, 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).

Application of modulated chlorophyll fluorescence and modulated chlorophyll fluorescence imaging to study the environmental stresses effect

Annali di Botanica, 2016
Chlorophyll (Chl) a fluorescence is a widely used tool to monitor the photosynthetic process in plants subjected to environmental stresses. this review reports the theoretical bases of Chl fluorescence, and the significance of the most important Chl fluorescence parameters.

Detection of the tulip breaking virus (TBV) in tulips using optical sensors [PDF]

, 2009
The tulip breaking virus (TBV) causes severe economic losses for countries that export tulips such as the Netherlands. Infected plants have to be removed from the field as soon as possible.

A Cheap Chlorophyll a Fluorescence Imaging System

Photosynthetica, 2000
A cheap chlorophyll (Chl) a fluorescence imaging system was developed for measuring leaf areas of 30×45 cm. Uniform saturating irradiances were created using CuSO4 filtered radiation from stroboscopes. The system was tested using maize leaves treated with diuron. Comparison was made with a small-area-measuring pulse amplified modulation Chl fluorometer.

OsCPK12-OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice. [PDF]

Adv Sci (Weinh)
OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

Chlorophyll fluorescence imaging as a tool to evaluate calyx senescence during the ripening of persimmon fruit treated with gibberellic acid

, 2021
The effect of gibberellic acid (GA) on retarding loss of persimmon firmness and fruit coloration has been previously reported. Nevertheless, information about the effect of this treatment on calyx senescence is lacking.
