Defects in leaf carbohydrate metabolism compromise acclimation to high light and lead to a high chlorophyll fluorescence phenotype in Arabidopsis thaliana [PDF]

, 2012
Background: We have studied the impact of carbohydrate-starvation on the acclimation response to high light using Arabidopsis thaliana double mutants strongly impaired in the day- and night path of photoassimilate export from the chloroplast.

A non-destructive method for monitoring the ripening of tomatoes based on their induction of chlorophyll fluorescence

Journal of Agricultural Engineering, 2020
Maturity is one of the most important factors associated with assessing the quality of tomatoes. The aim of this study is to develop a new device to measure the degree of ripeness of tomato fruits based on chlorophyll fluorescence.

Chlorophyll a + b Content and Chlorophyll Fluorescence in Avocado

Journal of Agricultural Science, 2012
Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m -2 in TxS240 to 4320 mg m -2 in Simmonds.

Application of chlorophyll fluorescence in fruit science [PDF]

1st PhotosynthOS Conference - Book of abstracts, 2023
The wide range of research on chlorophyll fluorescence (ChlF) demonstrates its usefulness in many plant biology, agronomy, and ecology research areas. Perennial fruit trees are frequently exposed to various biotic and abiotic stresses throughout their lifespan, limiting their crop quality and yield.

Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity

Advanced Science, EarlyView.
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Fluorescence Decay Studies of Chlorophyll a in Vivo

Biophysical Journal, 1965
The study of the fluorescence of chlorophyll a offers a useful approach toward better understanding of the primary act of photosynthesis. This paper describes new measurements of the decay of chlorophyll a fluorescence in vivo, made with a considerably improved oscilloscopic-display technique.
