Soluble peroxidase from winter wheat seedlings with phenoloxidase-like activity.
Peroxidase isozymes from winter wheat (Triticum aestivum L. cv Orso) seedlings extracts showed phenoloxidase-like activity, becoming visible on polyacrylamide gels also in the absence of hydrogen peroxide. The results obtained after a characterization of the two activities, based on their substrate specificity, on their selective inhibition, and on the possible occurrence of artifacts, suggeste...
متن کاملAdaptive Changes in ATPase Activity in the Cells of Winter Wheat Seedlings during Cold Hardening.
A cytochemical study of ATPase activity in the cells of cold hardened and nonhardened winter wheat (Triticum aestivum L. cv. Nongke No. 1) seedlings was carried out by electron microscopic observation of lead phosphate precipitation. ATPase activity associated with various cellular organelles was altered during cold hardening. (a) At 22 degrees C, high plasmalemma ATPase activity was observed i...
متن کاملUltrastructural and Enzymic Studies of Cell Membranes from Ice-encased and Noniced Winter Wheat Seedlings.
A marked increase in the amount of cisternal-like cytoplasmic membranes was observed after ice encasement of winter wheat (Triticum aestivum L.) seedlings. Linear sucrose gradients were employed to separate the various membrane components of the microsomal membrane fraction. NADH- and NADPH-cytochrome c reductase, two specific enzyme markers for plant endoplasmic reticulum (ER) were used to loc...
متن کاملActivity of Fungicides Against Epiphytic Yeast-Like Fungi of Winter Wheat
In a field experiment the susceptibility of yeast-like fungi to selected fungicides with the active ingredients (a.i.) propiconazole, epoxyconazole, kresoxim-methyl, fenpropimorph, carbendazim, prochloraz and flusilazole, was analyzed. The direct effect of the fungicides on the colonies of yeast-like fungi was determined based on antibiograms – the diffusion method. The survival rate of the iso...
متن کاملEffects of iron and cupper ions on sulforaphane content and peroxidase activity in Lepidium draba seedlings
Sulforaphane (SFN) is an isothiocyanate which is produced through glucoraphanin hydrolysis via myrosinase activity. In the present study, SFN content and peroxidase activity has been assessed in treated Lepidium draba seedlings with different concentrations of iron and copper during 8 and 16 hours treatment. The results showed that the SFN content drastically elevated at treatment with...
