Ascochyta blight is a major biotic constraint of faba bean (Vicia L.) production and productivity worldwide caused by fabae. No studies have been performed in Algeria to identify A. fabae isolates or assess their pathogenicity, therefore information on local insufficient. Herein, 14 were obtained from samples identified based morphological traits phylogenetic analysis internal transcribed space...

Heat shock proteins (Hsps) and other molecular chaperones perform diverse physiological roles. One is to facilitate, in part, organismal thermotolerance, of which the functional consequences depend on Hsp70 concentration and developmental stage in Drosophila melanogaster. To test whether an Hsp70-thermotolerance relationship is a general phenomenon within Drosophila, I assayed Hsp70 concentrati...

Because of significant yield losses caused by fungal pathogens, new efficient and environmentally safe methods pest control are needed, amphiphilic compounds (biosurfactants) produced many microbes considered a good alternative. In the present study, biosurfactants rhizosphere isolate Bacillus mojavensis P1709 were assessed for their ability to protect postharvest cherry tomatoes from decay myc...

Fruit maturity for seed production can occur at various times because of the continual flowering pepper plants. Accordingly, seeds with different are acquired as fruits collected in a single harvest. Immature obtained this harvest may lead to decrease quality lots. Therefore, research aimed evaluate influence four endophytic bacteria strains (Pseudomonas fluorescens strain L5b, Pseudomonas gess...

Sequences from three gene regions from the nuclear and mitochondrial genomes were used to examine the extent and nature of hierarchical structure in the Drosophilamojavensis cluster (Drosophila arizonae, D. mojavensis and D. navojoa) of the D. repleta species group. To determine the genetic divergence of these three species, sequence data were analyzed using maximum parsimony and population agg...

The mojavensis cluster of the repleta species group of Drosophila (Drosophilidae: Diptera) consists of three species. One is newly described as D. navojoa. A second species, described here as D. arizonae, replaces D. arizonensis, which has become a junior subjective synonym for D. mojavensis, the third species in the cluster. A phylogeny of the three species is presented, based on chromosomal i...

Physalis alkekengi L. has been used as anti-infective plant in Iranian traditional medicine. To investigate antifungal activity of the plant extract, wild plant was collected and identified and the aerial parts were air dried and powdered subsequently macerated in solvent. Extracts were concentrated by rotary evaporator at 60 C under reduced pressure. Aqueous, ethanol and methanol extracts were...

indiscriminate and excessive uses of antibiotics may be lead promote the emergence of antibiotic-resistant microorganisms and side effects in patients. therefore the researchers recently have focused on the use of natural resources, especially medicinal plants. ruta graveolens is a kind of medical plants which contains antifungal and antibacterial components and use in traditional medicine in i...
