the preliminary result of a survey conducted on xylaria species in the north of iran is presented. based on morphological examination of fungal specimens collected from guilan, mazandaran and golestan provinces, eight species including xylaria arbuscula, x. cubensis, x. filiformis, x. hypoxylon, x. longipes, x. multiplex, x. pannosa, and x. polymorpha were identified. among the identified speci...

The plasma membrane H-ATPase generates an electrochemical gradient of H across the plasma membrane that provides the driving force for solute transport and regulates pH homeostasis and membrane potential in plant cells. Recent studies have demonstrated that phosphorylation of the penultimate threonine in H-ATPase and subsequent binding of a 14-3-3 protein is the major common activation mechanis...

Cell suspensions of Marchantia polymorpha hydrogenate progesterone to 5alpha-pregnane-3,20-dione. Structure elucidation of the product was achieved by comprehensive NMR analyses.

The antimicrobial activity of methanol extracts three thalloid liverworts, Marchantia polymorpha, Conocephalum conicum and Pellia endiviifolia bis-bibenzyl marchantin A, the most dominant compound in extract M. have been investigated this research. 1H-NMR spectroscopy revealed that polymorpha P. liverwort contain terpenes, oils, sugars bis-bibenzyls, while these specific macrocyclic compounds w...

Ornamental aquaculture is one of the main sources non-native species worldwide. Unintentionally transported “hitchhiking” organisms have been previously recorded; although most these are from tropical regions, here we report on first accidental transport zebra mussel (Dreissena polymorpha) in a shipment ornamental Aegagropila linnaei (Chlorophyta) Russia to Czech Republic. This invasive listed ...

In this study, some biochemical responses of Beta-Cyfluthrin (β-CF), which is a commercial insecticide in Dreissena polymorpha, were investigated. The 96 hour LC50 value β-CF on D. polymorpha was calculated as 509.62 µg L-1. exposed to subletal concentrations (1/16, 1/8 and 1/4 value: 32, 64 128 L-1) for 24 hours. Malondialdehyde (MDA) reduced glutathione (GSH) levels Acetylcholinesterase (AChE...

Plants have evolved several ways to remain dormant until the time is right for growth. For example, seeds maintain dormancy through the antagonistic effects of the phytohormones abscisic acid (ABA) and gibberellic acid. Auxin (indole-3-acetic acid [IAA]), in turn, regulates ABA-induced seed dormancy through its interaction with the ABA signaling pathway (Liu et al., 2013). Dormancy is also cruc...

An array of vectors have been identified that pose a risk spreading invasive alien species (IAS), from personal protective equipment to large such as vehicles and boats. Biosecurity practices remove and/or kill IAS reduce the accidental spread. The effectiveness biosecurity protocols suitable for is little tested requires development. One widely-used method high-pressure hot water spray machine...
