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...
زمینه و هدف: بیماریهای عفونی، یکی از عوامل مهم مرگ و میر در جهان است. بهعلت مقاومت تعدادی از باکتریهای بیماریزای انسانی به آنتیبیوتیکها، استفاده از داروهای طبیعی و گیاهی برای کنترل این عوامل روبه افزایش است. هدف از این تحقیق، بررسی اثر ضدباکتریایی عصارهی گلسنگ ramalinahyrcanasipman علیه چند باکتری گرم مثبت و گرم منفی است. مواد و روشها: عصارهی اتانولی گلسنگ مورد نظر با استفاده از دس...
Bryophytes (liverworts, hornworts and mosses) comprise the three earliest diverging lineages of land plants (embryophytes). Marchantia polymorpha, a complex thalloid Marchantiopsida liverwort that has been developed into a model genetic system, occupies a key phylogenetic position. Therefore, M. polymorpha is useful in studies aiming to elucidate the evolution of gene regulation mechanisms in p...
During the last decade methylotrophic yeasts have gained increasing interest, both for fundamental (van der Klei and Veenhuis, 1996) and applied purposes (van Dijk et al., 2000; Gellissen, 2000). The special value of these yeasts (mainly Pichia pastoris and Hansenula polymorpha) in fundamental research is undoubtedly related to studies on the principles of peroxisome homeostasis (biogenesis vs....
