To shed light on the genetic equipment of the beneficial plant-associated bacterium Pseudomonas brassicacearum, we sequenced the whole genome of the strain NFM421. Its genome consists of one chromosome equipped with a repertoire of factors beneficial for plant growth. In addition, a complete type III secretion system and two complete type VI secretion systems were identified. We report here the...

A series of compounds representing four major pesticide groups were tested for toxicity to beneficial insects representing four different insect orders: Coleoptera (Coccinellidae), Hemiptera (Anthocoridae), Hymenoptera (Aphelinidae), and Neuroptera (Chrysopidae). These materials included organophosphates (methidathion, esfenvalerate and phosmet), carbamates (carbofuran, methomyl and carbaryl), ...

the rice fields consist of diverse fauna of arthropoda because of both subterranean and aquatic ecosystems. in this research, the fauna of predator beetles including carabidae, coccinellidae, staphylinidae, malachiidae, and their population fluctuation were studied in mazandaran province during 2002-2006. a number of 13 carabid species, one staphylinid species, six coccinellid species, and two ...

abstract background: the disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6g. methods: atotal of 568 iranian soldiers went under study for isolation and identification of yeast speci...

The nemertide toxins from the phylum Nemertea are a little researched family of neurotoxins with potential for development as biopesticides. Here we report recombinant production α-1 (α-1), 65-residue inhibitor cystine knot (ICK) peptide Lineus longissimus, known to target insect voltage-gated sodium channels. insecticidal activity was assessed and compared well characterised ICK venom peptide,...

background dermatophytes are a group of keratinophilic fungi worldwide, which can infect the skin, hair and nails of humans and animals. this genus includes several species that present different features of dermatophytosis. although, laboratory diagnosis of dermatophytes is based on direct microscopy, biochemical tests and culture, these manners are expensive, time consuming and need skilled s...

Influencing cancer metabolism by lifestyle changes is an attractive strategy as - if effective - exercise-induced problems may be less severe than those induced by classical anti-cancer therapies. Pursuing this idea, clinical trials evaluated the benefit of e.g. different diets such as the ketogenic diet, intermittent caloric restriction and physical exercise (PE) in the primary and secondary p...

Objective(s): Artemisia species are important medicinal plants throughout the world. Some species are traditionally used for their anti-inflammatory effect. The present study was designed to isolate sesquiterpene fractions from several Artemisia species and evaluate their anti-inflammatory activities on key mediators and signaling molecules involved in regulation of in...

Mutualism can be favored over exploitation of mutualism when interests of potential heterospecific partners are aligned so that individual organisms are beneficial to each others' continued growth, survival, and reproduction, that is, when exploitation of a particular partner individual is costly. A coral reef sponge system is particularly amenable to field experiments probing how costs of expl...
