A new species, Blitum venetum Iamonico, Argenti, Sciuto & Wolf is described from the Dolomites Massif (North-Eastern Italy) on basis of molecular analyses (nuclear ITS and plastid trnL-F regions) morphological investigation. The species similar to B. bonus-henricus californicum, but it differs these taxa by characters leaves (width, pubescence, margins), inflorescence (presence bracts),...

Research at 10 locations in coastal subtropical Queensland, Australia, has shown that salt marshes contained heterogeneous distributions of eggshells of the pest and vector mosquito Aedes vigilax (Skuse) (Diptera:Culicidae). The eggshell distribution was related to specific vegetation assemblages, with a mix of the grass, Sporobolus virginicus (L.) Kunth (Poales: Poaceae), and the beaded glassw...

Phytochemical investigation of the roots of Salsola imbricata allowed to two new bioactive biphenylpropanoids (1) and (2) named, biphenylsalsonoid A and B, respectively. Their structures were established through spectroscopic methods (1D and 2D NMR, (ES)-HRMS, and IR). The isolates were tested for their antioxidant activity using DPPH• and ABTS•+ assays. 1 and 2 showed a moderate activity towar...

Amplified fragment length polymorphism (AFLP) is a powerful fingerprinting technique that is widely applied in ecological and population genetic studies. However, its routine use has been limited by high costs associated with the optimization of fluorescently labelled markers, especially for individual study systems. Here we develop a low-cost AFLP protocol that can be easily transferred betwee...

The fungus Polymyxa betae is an obligate parasite of the roots of many plants of the family Chenopodiaceae. In the sugar beet, it acts as a vector of beet necrotic yellow vein virus, the agent of a serious disease known as rhizomania. With indirect methods of analysis, such as bioassay, one can establish only the presence or absence, but not the quantity, of P. betae in soil. A new method based...
