Pelargonium zonate spot virus (PZSV) is identified recently in tomato plants in the United States. To develop serological diagnostic tools for the detection of this virus, the production of good quality antibodies is a necessity. The coat protein (CP) gene of a California isolate of PZSV was cloned into a bacterial expression vector (pTriEX-4 Ek/LIC). The plasmid pTriEX-4-PZSV-CP was transforme...

background: nanosilver particles are among the potentially candidates for modulating the redox status and changing the growth, performance and quality of plants because of their physicochemical characteristics.   objective: this study was carried out to elucidate the potential effects of nanosilver particles application on variations of photosynthetic pigments (chlorophyll and carotenoids) and ...

background staphylococcus aureus is one of the most causative organisms in the skin wound infections. development of resistant s. aureus to current treatments in individuals with low immunity is a global concern. the aim of this study was to evaluate the efficacy of herbal formulation against skin wound infection. methods the efficacy of herbal formulation containing oliveria decumbens and pela...

We report an experiment designed to investigate whether olfactory cues can influence people's judgments of facial attractiveness. Sixteen female participants judged the attractiveness of a series of male faces presented briefly on a computer monitor using a 9-point visual rating scale. While viewing each face, the participants were simultaneously presented with either clean air or else with 1 o...

Antimicrobial activities of two ethanolic extracts, made from fresh and dried leaves of Pelargonium radula (Cav.) L'Hérit, were tested against fourteen species of bacteria and fifteen species of fungi. The well-diffusion method indicated the strongest activity against Pseudomonas aeruginosa. The broth dilution method revealed that the most sensitive microorganisms were Bacillus pumilus, Bacillu...

The search for new insecticides to control dengue fever, chikungunya, and Zika vectors has gained relevance in the past decades. The aim of the present study was to evaluate the larvicidal action of essential oils (EOs) from Thymus vulgaris, Salvia officinalis, Lippia origanoides, Eucalyptus globulus, Cymbopogon nardus, Cymbopogon martinii, Lippia alba, Pelargonium graveolens, Turnera diffusa, ...

Water is among the most important factors affected growth, yield and quality of medicinal aromatic plants since its deficiency may cause serious growth harms losses. Egypt suffers from a scarcity water, so each drop should be preserved. Therefore, objective present study was to determine suitable irrigation treatment (120, 100 80% ETo (evapotranspiration) humic acid amounts (control), 1.0, 1.5 ...
