Bacterial wilt is a common disease that causes severe yield and quality losses in many plants. In the present study, we used the model Ralstonia solanacearum-Arabidopsis thaliana pathosystem to study transcriptional changes associated with wilt disease development. Susceptible Col-5 plants and RRS1-R-containing resistant Nd-1 plants were root-inoculated with R. solanacearum strains harbouring o...

Seed weight is a very important and complex trait in rapeseed (Brassica napus L.). The seed weight of rapeseed shows great variation in its natural germplasm resources; however, the morphological, cytological and genetic causes of this variation have remained unclear. In the present study, nine highly pure inbred rapeseed lines with large seed weight variation and different genetic backgrounds ...

Transgenic maize MON88017, expressing the Cry3Bb1 toxin from Bacillus thuringiensis (Bt maize), confers resistance to corn rootworms (Diabrotica spp.) and provides tolerance to the herbicide glyphosate. However, prior to commercialization, substantial assessment of potential effects on non-target organisms within agroecosystems is required. The MON88017 event was therefore evaluated under field...

Introduction: Nuclear moisture density gauges are widely used in construction industry in different countries across the world, including Ghana, on a large scale. Like all irradiating devices, the nuclear gauges should be subjected to radiation safety assessment based on radiation protection and safety principles. Regarding this, the objective of this research was to i...

background & aim: treatment with herbal medicines is very popular in all over the world. nowadays, using medicinal plants has increased because of undesirable effects of the chemical drugs. more than 10000 plant species are used for medicinal purposes, mainly as traditional medicines in the treatment of dysmenorrhea.  the aim of this study was determining the rate of herbal remedies to reli...

the aim of this study was to assess the effects of heavy metal tolerant soil microbes inoculation on growth and metal uptake of pearl millet (pennisetum glaucum), couch grass (triticum repens) and alfalfa (medicago sativa) in a soil spiked (and subsequently aged) with increasing concentrations of pb. a soil sample (soil 1) was spiked with increasing (0 to 1500 mg/kg) concentrations of pb and in...

background & aim: secondary metabolites with bioactive and functional properties in essence of aromatic plants can be useful for improvement of quality and persistence of food as natural preservative.  the aim of this study was to evaluate the in vitro antibacterial of essential oils of some of the medicinal plants collected from chaharmahal va bakhtiari province, iran. experimental: the e...

I enjoy designing and constructing systems that achieve robustness by adapting to changing constraints. My recent focus has been in decentralized systems, including mechanisms for expressing and enforcing security relationships among mutually distrustful administrative domains, securely deploying mobile agents, and the efficient dissemination of on-line content. My hope is that this work will f...
