Biotechnological applications, especially transgenic plants, probably hold the most promise in augmenting agricultural production in the first decades of the next millennium. However, the application of these technologies to the agriculture of tropical regions where the largest areas of low productivity are located, and where they are most needed, remains a major challenge. In this paper, some ...

We conducted a comparative analysis of biochemical parameters for the ascorbate-glutathione cycle in non-transgenic and transgenic Nicotiana tabacum, plants cultivated heavy metal polluted soils. Transgenic had their genome bacterial acdS-gene encoding 1-aminocyclopropane-1-carboxylate deaminase (ACC-deaminase) enzyme. The introduction elevated concentrations copper, chromium, lead ions into so...

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...

The present study deals with the establishment of rolA-transgenic and rolB-transgenic plants for first time through Agrobacterium tumefaciens mediated transformation, exploiting inherent morphogenic potential an important medicinal plant, Bacopa monnieri (L.) Wettst. showed integration expression rolA rolB genes respectively, whereas Ri-transformed rolA, rolB, rolC rolD genes. Morphogenic diffe...

In an attempt to improve stress tolerance of tomato (Lycopersicon esculentum) plants, an expression vector containing an Arabidopsis C-repeat/dehydration responsive element binding factor 1 (CBF1) cDNA driven by a cauliflower mosaic virus 35S promoter was transferred into tomato plants. Transgenic expression of CBF1 was proved by northern- and western-blot analyses. The degree of chilling toler...

dehydrogenase, which catalyzes the biosynthesis of mannitol from fructose, was cloned from Escherichia coli and transferred to poplar (Populus tomentosa Carr.) through Agrobacterium-mediated transformation. The transgenic plants were screened and selected on Murashige and Skoog (MS) medium containing 30 – 50 mg l – 1 kanamycin and verified by polymerase chain reaction (PCR) and Southern blottin...

transgenic tomato plants of south indian cultivar arka vikas were developed using agrobacterium strain eha 105, harbouring bt cry2a gene with a construct containing 35s camv promoter, ocs terminator and nptii selectable marker, through agrobacterium-mediated transformation. this study was conducted to improve the regeneration and transformation protocol for south indian cultivar arka vikas. hyp...

Physiological responses to water stress in hybrid poplar (INRA 7171-B4, Populus tremula L. x P. alba L.) lines transformed to overexpress a pine cytosolic glutamine synthetase (GS1) gene were compared with those of non-transgenic plants. Before, during and after a drought treatment, net photosynthetic rates (Anet) were higher in transgenic than in non-transgenic plants. Stomatal conductance (gs...
