CHLOROPHYLL AND CAROTENOID CONTENTS IN TOMATO AND CUCUMBER PLANTS IN RELATION TO DIMETHOATE AND PROFENOFOS APLLICATION [PDF]

Journal of Plant Protection and Pathology, 2002
The insecticides, dimethoate and profenofos were sprayed on tomato and cucumber plants at the fruiting stage. Effect of these insecticides by different concentrations (half, one, and twice recommended rates) on chlorophyll “a”,”b”, total and carotenoid ...

Effects of Light Intensity on Development and Chlorophyll Content in the Arabidopsis Mutant Plants with Defects in Photosynthesis [PDF]

Journal of Stress Physiology & Biochemistry, 2015
The developmental stages and adaptability to different light intensity (150 µmol*m-2*s-1 and 100 µmol*m-2*s-1) in Arabidopsis mutant lines with defects of photosynthetic apparatus were analyzed. Plant development in the mutant lines depended on the light

THE INFLUENCE OF STRONG AND WEAK ACID UPON AGGREGATION AND PHEOPHYTINIZATION OF CHLOROPHYLL A AND B

Indonesian Journal of Chemistry, 2010
Chlorophyll is green pigment that can be found in plant chloroplast. Higher plants usually have two kinds of chlorophylls, chlorophyll a and b. These green pigments are easily degraded by temperature, light intensity, oxygen, acid, and water.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Peculiarities of the Growth and Photosynthetic Pigments Content in Algaeculture of Acutodesmus dimorphus (Tupin) P.M. Tsarenko under Salt and Acetate Stresses [PDF]

Journal of Stress Physiology & Biochemistry, 2017
The objective of this research was to investigate the effect of salt (NaCl) and acetate (NaC2H3O2) stresses on the pattern of biomass accumulation and photosynthetic pigments content in algae culture of the freshwater green alga Acutodesmus dimorphus ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

FEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Thriving across seawater depths: How blue light shapes a large PSI supercomplex and specific photosynthetic traits in the seagrass Posidonia oceanica

Plant Communications
Seagrasses are marine flowering plants that perform oxygenic photosynthesis both under high, white sunlight and under low, blue-green light, conditions fundamentally different from those experienced by land plants.

Productivity of triticale depending on the content of photosynthesizing pigments at anthesis

Рослинництво та ґрунтознавство, 2021
Photosynthetic pigments play an important role in the accumulation of dry matter and they can be the markers of stress. Change in the ratio of chlorophyll A and B indicates physiological changes and adaptation of the organism to changes of environmental ...
