manipulation of different genes in crop plants to get desirable characters has become an important tool of plant biotechnology. in the current study, cotton variety mnh-786 was modified for its characteristics to show resistance against lepidopteran insects and herbicide by transformation of cry1ac+cry2a and gtgene cloned in a different cassette under 35s promoter. mature embryos of cotton mnh-...

To increase the production level of heterologous proteins in plants, strategies such as choice of strongerpromoters, optimization of codon usage and specific localization of foreign proteins are of major concern.Calcitonin (CT), a 32 amino acid polypeptide is a powerful and specific inhibitor of bone resorption and isused to treat several human diseases. Calcitonin activity is...

The testing and release of genetically modified organisms (GMOs)—in particular GM plants—is tightly regulated internationally to prevent any negative effects on the environment or human health. However, these regulations are based on transgenic organisms and do not discriminate between transgenic plants and cisgenic plants, although we believe that they are fundamentally different (see sidebar)...

Transgenesis is a term first coined by Gordon and Ruddle (1983) to describe a technology which allows the transfer of functioning genes between organisms, irrespective of species barriers. An organism so transformed is called transgenic. In usage, the term is employed mostly in relation to higher organisms and now commonly extends to include all plants and animals which have been genetically ma...

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...

Jute (Corchorus sp.) is naturally occurring, biodegradable, lignocellulosic-long, silky, golden shiny fiber producing plant that has great demands globally. Paper and textile industries are interested in jute because of the easy availability, non-toxicity and high yield of cellulosic biomass produced per acre in cultivation. Jute is the major and most industrially used bast fiber-producing crop...

Cervical cancer is linked to infection with human papillomaviruses (HPV) and is the third most common cancer among women worldwide. There is a strong demand for the development of an HPV preventive vaccine. Transgenic plants expressing the HPV major capsid protein L1 could be a system to produce virus-like particles for prophylactic vaccination or could even be used as edible vaccines to induce...

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...
