Dog rose (Rosa canina L.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as Rosa hybrid and Rosa floribunda. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and d...

In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...

A method of detecting lead was developed using square wave anodic stripping voltammetry (SWASV) with DNA-carbon nanotube paste electrode (CNTPE). The results indicated a sensitive oxidation peak current of lead on the DNA-CNTPE. The curves were obtained within a concentration range of 50 ngL(-1)-20 mgL(-1) with preconcentration time of 100, 200, and 400 sec at the concentration of mgL(-1), μgL(...

The production of antileukemic enzyme methionine γ-lyase (MGL) in distinctly related bacteria, Citrobacter freundii and in their recombinants expressing the Vitresocilla hemoglobin (VHb) has been studied. This study concerns the potential of Citrobacter freundii expressing the Vitreoscilla hemoglobin gene (vgb) for the methionine γ- liyase production. Methionine γ- liyase production by Citrobac...

The study was undertaken to assess the dosage-mortality ratio and toxic effects of Piper guineense fruit extracts on the adults of Biomphalaria pfeifferi, the snail intermediate host of Schistosoma mansoni, which causes intestinal schistosomiasis. The result showed significant toxic effects with crude ethanol and hot water fruits extracts. The estimated lethal dose concentration by arithmetic m...

Individual lines of Vitis vinifera Barbera and Chardonnay were obtained by in vitro culture of axillary buds collected from phytoplasma-affected mother plants. The molecular assays did not detect the “flavescence dorée” (FD) phytoplasma in the 66 lines tested after 6-9 months of culture, while the “bois noir”-associated phytoplasma was detected in 22 out of 50 lines. Despite the observed ineffi...
