התחבר הרשם

Remote sensing of the health status of vegetation should be possible by using UV laser-induced fluorescence; nevertheless, the molecular origin of the leaf blue-green fluorescence emission is still unknown. In order to investigate possible relations of this fluorescence to the photosynthetic

Autoradiographs of (22)Na-loaded bean (Phaseolus vulgaris L. cv. ;Brittle Wax') leaf slices showed that most of the tracer was concentrated in vascular tissue. Rubidium-86 was uniformly distributed in slices that had been incubated in darkness; after incubation in the light many small dark spots

Four hydrogen peroxide detecting probes, 3,3'-diaminobenzidine (DAB), Amplex Red (AR), Amplex Ultra Red (AUR) and a europium-tetracycline complex (Eu(3)Tc) were infiltrated into tobacco leaves and tested for sensitivity to light, toxicity, subcellular localization and capacity to detect H(2)O(2) in

Studies on the abscission of blue lupin leaves : II. effects of kinetin and light on pulvinar and other types of explants.

התחבר הרשם

The responses of three types of explants of blue lupin leaves are considered: pulvinar explants, consisting of the pulvinar region alone, petiolar explants, consisting of the pulvinar region plus petiole and laminar explants consisting of the pulvinar region plus leaflets. Abscission is accelerated

התחבר הרשם

Cadmium is a toxic heavy metal causing iron deficiency in the shoot and light sensitivity of photosynthetic tissues that leads to decreased photosynthetic performance and biomass production. Light intensity had strong impact on both photosynthetic activity and metal accumulation of cadmium-treated

Zeaxanthin deficiency enhances the high light sensitivity of an ascorbate-deficient mutant of Arabidopsis.

התחבר הרשם

The ascorbate content of plants is usually increased in high light (HL), implying a function for ascorbate in the acclimation of plants to HL. Nevertheless, the importance of ascorbate in HL acclimation has not yet been tested directly. Here, we report on the acclimation process of an

1. Spinach leaves contain a "Spinach Protein Factor" (SPF) which increases light sensitivity of colloidal chlorophylls in aqueous solution (Terpstra, 1967). SPF activity, measured in different fractions of spinach-leaf acetone-powder extracts obtained by gel filtration on DEAE- and CM-Sephadex, runs

The blue light-specific response of Vicia faba stomata acclimates to growth environment.

התחבר הרשם

Stomata in epidermal strips from growth chamber-grown Vicia faba leaves opened less in response to white light than did stomata from greenhouse-grown leaves. Chlorophyll-mediated, red light-stimulated opening was similar in stomata from the two growth conditions, but stomata from the growth chamber

התחבר הרשם

In this study, the photosynthetic light response curves were measured for Liquidambar formosana during the leaf senescence from October to December in 2014. The measurements were simulated by a photosynthetic light response model (Ye model) and the conventional non-rectangular hyperbola model, in

A 38-year-old man presented with severe methanol intoxication after inhaling methanol over a period of 36 hours in a poorly-ventilated laboratory. He complained of visual disturbances, mild photophobia, hyperventilation and nausea. Laboratory results showed severe metabolic acidosis with a toxic

The retinal G protein-coupled receptor (RGR) enhances isomerohydrolase activity independent of light.

התחבר הרשם

Rod and cone visual pigments use 11-cis-retinal, a vitamin A derivative, as their chromophore. Light isomerizes 11-cis- into all-trans-retinal, triggering a conformational transition of the opsin molecule that initiates phototransduction. After bleaching all-trans-retinal leaves the opsin, and light
