The present work aimed to compare antioxidant response and lipid peroxide detoxification capacity of an arctic-alpine species Arabis alpina its close relative model Arabidopsis thaliana under acute short duration (3 h 6 h) UV-B stress (4.6 8.2 W/m2). After 3 exposure UV-B, A. showed lower peroxidation H2O2 accumulation when compared thaliana. Moreover, Fv/Fm value dropped 0.70, while 0.75 indic...

The name Isoetes pedersenii H.P. Fuchs (Lycophyta), a species known only from the Mburucuyá National Park, Corrientes, Argentina, is validated. Observations were carried out on herbarium material with stereoscopic, light and scanning electron microscopes. The species is described and typified. A diagnosis and discussion about its distribution and its relationship with the morphology of other sp...

Recent studies show that Mortierella elongata can perform plant-growth promotion across different types of crops, including bahiagrass, corn, tomato, squash, and watermelon. Compared to the well-known species have plant-growth-promotion abilities (e.g., mycorrhizal fungi, Trichoderma), growers, agents, stakeholders are not familiar with "Mortierella" despite important role these fungal taxa pla...

The aim of this work was to study the chemical composition, antioxidant and antibacterial properties of Achillea distans Waldst. et Kit. subsp. distans and Achillea distans Waldst. et Kit. subsp. alpina Rochel, from the Rodna Mountains (Romania). The identification and quantification of major phenolic compounds was performed by a HPLC-MS method. The total polyphenolic and flavonoid content was ...

The esterase profiles of 9 strains of Mortierella ramanniana grown on glucose and olive-oil media were determined by starch-gel electrophoresis. The enzymes produced on the oil medium were in most instances produced also on the glucose medium, but on the latter some additional esterase components were produced. The esterase patterns of the different strains varied widely; only one esterase was ...

Three β-cyclocitral-derived halolactones, which exhibit antifeedant activity towards storage product pests, were subjected to microbial transformation processes. Among the thirty tested strains of filamentous fungi and yeast, the most effective biocatalysts were Absidia cylindrospora AM336, Mortierella isabellina AM212 and Mortierella vinaceae AM149. As a result of regio- and enantioselective h...

AlPiNA is a symbolic model checker for High Level Petri nets. It is comprised of two independent modules: a GUI plugin for Eclipse and an underlying model checking engine. AlPiNA’s objective is to perform efficient and user-friendly, easy to use model checking of large software systems. This is achieved by separating the model and its properties from the model checking-related concerns: the use...

Canopy disturbances such as windthrow events have obvious impacts on forest structure and composition aboveground, but changes in soil microbial communities and the consequences of these changes are less understood.We characterized the densities of a soil-borne pathogenic oomycete (Pythium) and a common saprotrophic zygomycete (Mortierella) in nine pairs of forest gaps created by windthrows and...
