Metamitron, a Photosynthetic Electron Transport Chain Inhibitor, Modulates the Photoprotective Mechanism of Apple Trees

open access: yesPlants, 2021
Chemical thinning of apple fruitlets is an important practice as it reduces the natural fruit load and, therefore, increases the size of the final fruit for commercial markets.

The Cupric Ion as an Inhibitor of Photosynthetic Electron Transport in Isolated Chloroplasts [PDF]

open access: yesPlant Physiology, 1972
Strong inhibition of uncoupled photosynthetic electron transport by Cu(2+) in isolated spinach chloroplasts was observed by measuring changes in O(2) concentration in the reaction medium. Inhibition was dependent not only on the concentration of the inhibitor, but also on the ratio of chlorophyll to inhibitor.

Effects of ethylene inhibitor and promoter on photosynthetic characteristics of soybean (Glycine max) seedling leaves

open access: yes浙江大学学报. 农业与生命科学版, 2010
Different concentrations of ethylene inhibitor AVG (aminoethoxyvinylglycine) and promoter ACC (1-aminocylopropane-1-carboxylic acid) were sprayed to seedlings of soybean cultivar Tiefeng 31, and their effects on photosynthesis and CO2 response curves ...

Ethylene Suppresses Abscisic Acid, Modulates Antioxidant System to Counteract Arsenic-Inhibited Photosynthetic Performance in the Presence of Selenium in Mustard

open access: yesFrontiers in Plant Science, 2022
Arsenic (As) stress provokes various toxic effects in plants that disturbs its photosynthetic potential and hampers growth. Ethylene and selenium (Se) have shown regulatory interaction in plants for metal tolerance; however, their synergism in As ...

Hydrostatic Pressure: A Reversible Inhibitor of Primary Photosynthetic Processes

open access: yesZeitschrift für Naturforschung C, 1973
Abstract Primary photosynthetic processes under pressures of up to 1300 atm were studied by means of chlorophyll fluorescence induction (Kautsky-effect) and compared to simultaneous oxygen exchange transients determined polarographically. Chlorophyll fluorescence induction was affected by increased hydrostatic pressure in three distinct

Ethylene potentiates sulfur-mediated reversal of cadmium inhibited photosynthetic responses in mustard

open access: yesFrontiers in Plant Science, 2016
The potential of exogenous ethylene and sulfur (S) in reversal of cadmium (Cd)-inhibited photosynthetic and growth responses in mustard (Brassica juncea L. cv. Pusa Jai Kisan) were studied.

Regulatory role of gamma-aminobutyric acid in cyanobacteria challenged with UV-B: The implication of nitric oxide

open access: yesPlant Stress, 2022
The present study examined the alleviatory role of gamma-aminobutyric acid (GABA) in UV-B challenged nitrogen fixing cyanobacteria and the significant role of nitric oxide (NO) as a downstream signal in GABA-mediated responses.

On a new inhibitor of photosynthetic electron-transport in isolated chloroplasts

open access: yesZeitschrift für Naturforschung B, 1970
A halogenated benzoquinone has been found to inhibit the photosynthetic electron transport system in isolated chloroplasts. 2·10-6ᴍ of dibromo-thymoquinone inhibit the Hill- reaction with NADP, methylviologen or anthraquinone to 100%, but do not effect the photoreduction of NADP at the expense of an artificial electron donor.

Chlorophyll fluorescence technique as a rapid diagnostic test of the effects of the photosynthetic inhibitor chlorotoluron on two winter wheat cultivars

open access: yes, 2003
A modified chlorophyll fluorescence technique was evaluated as a rapid diagnostic test of the susceptibility of wheat cultivars to chlorotoluron. Two winter wheat cultivars (Maris Huntsman and Mercia) exhibited differential response to the herbicide. All
