A DNA microarray, comprising 70-mer oligonucleotides, representing 8,453 open reading frames (ORFs), was constructed based on the Bradyrhizobium japonicum strain USDA110 genomic sequence. New annotation predicted 199 additional genes, which were added to the microarray and were shown to be transcribed. These arrays were used to profile transcription in cells under a variety of conditions, inclu...

We focused on the impact of industrial wastes on the water quality of the El-Amia drain in Egypt and the effect of irrigation with industrial wastewater on the growth, cell membranes, photosynthetic pigment content, the antioxidant system and selected osmoprotectants (proline, total amino nitrogen and soluble sugars) in three crop plants: turnip, tomato and lettuce. Furthermore, the present wor...

The role of soil microbiota in plant stress management, though speculated a lot, is still far from being completely understood. We conducted a greenhouse experiment to examine synergistic impact of plant growth promoting rhizobacterium, Bacillus subtilis (BERA 71), and arbuscular mycorrhizal fungi (AMF) (Claroideoglomus etunicatum; Rhizophagus intraradices; and Funneliformis mosseae) to induce ...

drought is considered as one of the most important limiting factors for oil seed canola plant(brassica napus l.) growth and productivity in iran. on the basis of root and shoot dry weight asaffected by water stress exerted by peg 6000, out of 9 canola cultivars, a relatively tolerant (cv. aghaii)and a sensitive cultivar (cv. po4) were selected. their responses to low water potential with respec...

Azadirachta indica is an important multipurpose social-forestry species moderately tolerant to salinity stress. There is an increase in the demand for saline tolerant lines of neem. In the present study, a tissue culture method was optimized to obtain callus and regenerates from nodal explants and exposed them to different levels of saline concentration in MS were selected for the determination...

Directly upstream of the Halobacterium salinarum transducer genes basT and htpIV we identified two open reading frames (orfs) with significant homologies to genes encoding binding proteins for amino acids and compatible solutes, respectively. Behavioral testing of deletion mutants indicates that halobacterial chemotaxis towards branched-chain amino acids as well as compatible osmolytes of the b...

Soil salinity limits agricultural land use and crop productivity, thereby a major threat to global food safety. Plants treated with several phytohormones including cytokinins were recently proved as powerful tool enhance plant’s adaptation against various abiotic stresses. The current study was designed investigate the potential role of 6-benzyladenine (BA) improve broad bean (Vicia faba L.) to...

In pulse crops, synchronized flowering altered the source-sink relationship due to rapid translocation of nutrients from leaves developing pods. Additional nutrition through foliar feeding plays a vital role in production by stimulating root development, nodulation, energy transformation, various metabolic processes and increasing pod setting, thereby yield. Many researchers are trying reduce t...

Traditional mulch material (farmyard manure) has long been used in agriculture. However, recent developments have also introduced the scientific community and farmers to advanced chemicals such as potassium polyacrylamide (KPAM), which revolutionised concept of soil water-holding capacity many compared with other materials being used. To compare effect different organic inorganic amendment unde...

Anthropogenic activities have caused important increases in soil Cu levels not only in urban areas but also in croplands. This study was designed to find out the effect of different concentration of copper on physiological and biochemical changes in Eucalyptus camaldulensis seedlings. Seeds of Eucalyptus camaldulensis were grown in marble chips and irrigated with nutrient solution mixed with co...
