Application of wild Saudi plant extracts to control antibiotic resistant Staphylococcus aureus

Wild plants are always the promising sources to explore novel therapeutic agents. Kingdom of Saudi Arabia (KSA) has a wide collection from wild and medicinal plants that contains hundreds of precious species. Staphylococcus aureus is from the most clinically dangerous bacterial pathogens that could acquire many resistance types toward numerous chemical antibiotics. Seven wild KSA plants, e.g. Bassia eriophora, Blepharis...

Physiological and chemical characteristics of cultivated single cross maize (Zea mays L.) hybrids

Maize is the principle agricultural crop, considered the third important cereal crop in terms of its great economic importance as constitutes 70% of human food and animal fodder. So far, maize becomes crucial for starch, fructose and oil industries. Several maize breeding programs developed number of withstanding commercial hybrids against many diseases and characterized by high yield production. As hybrids vigor is...

The in vivo biosynthesis of antibacterial silver nanoparticles using red pepper (Capsicum annuum L) fruit extract

Green synthesis of nanoparticles using biological organisms is of increased demand by many scientific and economic sectors. Biosynthesis of silver nanoparticles was undertaken using aqueous extract from red fleshly sweet fruits of Capsicum annuum and the antibacterial activity of silver nanoparticles (Ag NPs) was investigated. We tracked color change of pepper extract from orange to deep dark brown after 10 mins of...

The role of bacteria on heavy-metals extraction and absorption by plants growing on multi-metal contaminated soils

Four bacterial isolates were examined for their ability to solubilize Cr, Cu, Pb and Zn in soils and for their effect on metals uptake by Zea mays and Sorghum bicolor plants. Bacillus subtilis DQ494445; Bacillus pumilus DQ49446, Pseudomonas pseudoalcaligenes DQ494447, and Brevibacterium halotolerans DQ494448 were added to Cr-rich soils and Cu-rich soils. B. pumilus and B. subtilis increase the availability of...

Selection of water deficit-tolerant banana cultivar through tissue culture techniques

Banana cultivation in Egypt is limited by water availability. The tolerance to occasional water stress was tested on small plantlets regenerated from shoot tip explants. Aseptic cultures of banana cultivars Maghraby, Valery, Grand Nain and Hindy were established and initiated on MS-basal medium supplemented with benzyladenine (BA, 3 mg/l) and agar (6 g/l). Growing explants were recultured, at 4 week intervals, on fresh...

Comparison between different serological methods for detdction of cowpea mosaic comovirus

Sensitivities of three serological tests; optimized Dot Immunobinding Assay (DIA), indirect Enzyme-Linked Immunosorbent Assay (ELISA) and Tissue Blot Immunobinding Assay (TBIA) were compared for detecting cowpea mosaic Como virus (CPMV) in different plant organs as well as in leaves of plants at different periods after inoculation. Results showed that indirect ELISA was more sensitive than indirect DIA. Indirect ELISA...

Induced resistance in chickpea against some seed-borne pathogenic fungi using the antioxidant, hydroquinone

In laboratory studies, the antifungal substance of antioxidant, hydroquinone at 5, 10, 15 and 20 mM reduced linear growth of two chickpea pathogenic fungi, Fusarium oxysporum f. sp. ciceris Schlect. Emend. Snyd & Hans. (2 isolates) and F. solani Mart. (4 isolates). The reduction in fungal linear growth was signify-cantly increased by increasing the concent-ration. The highest inhibitory effect of hydro-quinone at...

Genetic diversity among Ipomea carnea jacq. populations from different habitat types in Nile-Delta region of Egypt

Seed protein and isozyme variations were revealed by SDS-PAGE among 25 populations of Ipomea carnea Jacq. representing different localities and habitat types in Nile Delta region in Egypt. Genes expressions reflected as banding patterns of seed storage-proteins as well as of six isozymes (Acp, Akp, Est, Got, Per and Cbp) revealed a great inter-population variations. These variations indicate a high genetic diversity...

Biochemical and molecular markers associated with callus induction in some tomato cultivars

In this study, callus induction trait in different tomato genotypes were detected through three categories of genetically significant markers, morphological markers, protein-based markers and DNA- based markers (RAPD). Both molecular and biochemical markers associated with this trait offered a promising alternative to the morphological markers as they can be analyzed at a very early stage of plant development and mostly...

Epidemiological study on human Candidiasis in tanta hospitals, Egypt

In the present work Candida species were isolated from hospitalized patient samples for different underlying diseases admitted to Tanta El-Menshawy general hospital and Tanta university hospitals. The objective of this work is to study the isolation and identification of Candidia spp. from patient samples of (urine, stool, semen, C.S.F, oral and vaginal swabs) were directly culture on Sabouraud dextrose agar (SDA)...
