L-Ascorbic Acid Peroxidase
نویسندگان
چکیده
Euglena gracilis was found to contain a peroxidase that specifically requires L-ascorbic acid as the natural electron donor in the cytosol. The presence of an oxidation-reduction system metabolizing L-ascorbic acid was demonstrated in Euglena cells. Oxidation of L-ascorbic acid by the peroxidase, and the absence of ascorbic acid oxidase activity, suggests that the system functions to remove H202 in E. gracilis, which lacks catalase.

Effects of ascorbic acid on physiological and biochemical responses of Zinnia elegans L. to different levels of light intensity
The aim of this study was to investigate the effect of different light intensities and ascorbic acid on some physiological and biochemical characteristics of Zinnia elegans L. The experiment was designed as a completely randomized design in a form of split-plot with three replications. The treatments were consisted of three light intensity levels (600, 1200 and 1800 μmol m-2 s-1) as the main fa...

A pot experiment was conducted during spring and summer of 2017 at collage of agriculture of Isfahan University of Technology, Esfahan, Iran, in order to evaluate the effects of different concentrations of foliar ascorbic acid application on the response of sorghum (speedfeed cultivar) to salinity. Treatments included two salinity levels (0 and 100 mM NaCl) and five concentrations of ascorbic a...
متن کاملEffect of Salicylic Acid, Citric Acid and Ascorbic Acid on Post-harvest Quality and Vase Life of Gerbera (Gerbera jamesonii) Cut Flowers
Cut gerbera (Gerbera jamesonii) flowers are sensitive to microbial contamination and have short vase life. The effect of salicylic acid, citric acid and ascorbic acid (50, 100 and 200 mg l-1) was evaluated on vase life of gerbera flowers. Changes in vase life, water absorption, and bacterial population in stem and vase solution, also biochemical characteristics such as protein concentration, li...

Drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. To evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. Cultivars with two-level white seedless and khosh...
