transformation of plants using agrabacterium rhizogenes may affect secondary metabolite production as well as morphological changes. in this study, t-dna from ri plasmid in a. rhizogenes carrying pri15834-prt35s-gus was introduced into tobacco leaf segments to initiate development of transformed hairy roots. plant regeneration from transgenic roots used ms medium, and plants regenerated fro...

BACKGROUND: Nicotiana tobacco contains large amounts of alkaloid nicotine. Tobacco plant is used for smoking and causes many health problems since it is high in nicotine which is one of the widely-recognized toxic compounds with serious side effects for different body organs. Reducing nicotine content of this plant is a way to reduce its health hazards in cigarette smokers. Utilizing the new ...

The main aim of this study was to obtain the Crimean-Congo hemorrhagic fever virus (CCHFV) glycoprotein, through either stable transgenic plants or using a transient expression system, and determine the yield, quality and finally the immunogenicity of the plant-made CCHFV glycoprotein in a mouse model. We designed and synthesized a codon-optimized G1/G2 gene from the G1 and G2 parts of the CCHF...

Salinity is a major limiting factor for plant growth and development. To evaluate the impact of P5CS gene expression under in vitro salt stress condition, transgenic tobacco (Nicotiana plumbaginifolia) carrying P5CS gene and non-transgenic plants were treated with 0, 100, 150, 200 or 250 mM NaCl for 28 days. Proline content, lipid peroxidation and the activity of some antioxidant enzymes after ...

Recently, new molecular breeding and genetic engineering approaches have emerged to overcome the limitations of conventional breeding methods in generating disease-resistance transgenic plants. The use of antimicrobial peptides (AMPs) to produce transgenic plants resistant to a wide range of plant pathogens has achieved great success. Among huge number of AMPs, Dermaseptin B1 (DrsB1), an antimi...

expansins are cell wall proteins that due to changes in ph, causing the expansion of the cell wall .these proteins are causing deformation of walls through loosening hydrogen bonds between the cellulose and polymer matrix microfibrils .in this study, a root specific gene called atexpa18 -that directly affect the formation of root hairs and also its role  have been proved in other parts of the p...
