Assessment of salt tolerance in transgenic tobacco (Nicotiana tobacum L.) plants expressing the AUX gene
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...
متن کاملInheritance and expression of the mouse metallothionein gene in tobacco: impact on cd tolerance and tissue cd distribution in seedlings.
Genetically engineered seedlings obtained from self-fertilized transgenic tobacco (Nicotiana tabacum) contained and expressed the mouse metallothionein and kanamycin resistance marker genes and were more tolerant to cadmium stress than untransformed controls. Cadmium accumulation in leaves of transgenic seedlings exposed to a low, field-like Cd concentration (0.02 micromolar) was about 20% lowe...
متن کاملResponses of Transgenic Tobacco (Nicotiana plambaginifolia) Over-Expressing P5CS Gene Underin vitroSalt Stress
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 ...

متن کاملincreasing stems length and leaf area in transgenic tobacco plants expressing arabidopsis atexpa18 gene
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...
