Variation in the spatio- temporal expression of Insecticidal Genes in Cotton
Variations in the efficacy of insecticidal genes in transgenic cotton and the involved mechanisms need to be understood fully so as to plan rational resistance management strategies to retard the rate of resistance development and to control target pests effectively by enhancing the endotoxin expression through genetic or agronomic management.
Introduction of cry1Ab gene into cotton (Gossypium hirsutum) enhances resistance against Lepidopteran pest (Helicoverpa armigera)
The results showed that transgenic lines in T 1 progeny have appreciable level of resistance (40-60%) against lepidopteran pests in both green house and field conditions.
Camv 35 S is a Developmental Promoter Being Temporal and Spatial in Expression Pattern of Insecticidal Genes ( Cry 1 ac & Cry 2 a ) in Cotton
Stable integration and spatio -temporal expression of two insecticidal genes (Cry1Ac and Cry2A) in transgenic cotton was studied. Firstly, integration of both genes was confirmed in these advance
Expression of the cry1EC gene in castor (Ricinus communis L.) confers field resistance to tobacco caterpillar (Spodoptera litura Fabr) and castor semilooper (Achoea janata L.)
Castor (cv. DCS-9) has been transformed through Agrobacterium-mediated and particle gun bombardment methods using appropriate vectors containing the Bt chimeric gene cry1EC driven by enhanced 35S promoter to demonstrate integration and inheritance of the introduced genes.
Camv 35S is a Developmental Promoter Being Temporal and Spatial in Expression Pattern of Insecticidal Genes (Cry1ac & Cry2a) in Cotton.
The study conducted suggested that CaM V 35S promoter is a developmental promoter and also it triggered research to find out new possible promoters to make expression of insecticidal genes consistent throughout life of cotton plant.
Agrobacterium Mediated Genetic Transformation of Tomato using Cry 2 A Gene
An attempt was made to develop transgenic tomato plants harbouring cry2A gene through Agrobacterium mediated transformation, which were reported to be resistant to lepidopteran insect pests.
The focus would shift from frequency of transformation to the development of tailor-made transformation system and concerns about uncontrolled spread of the transgene(s) in ecosystem will become irrelevant in the near future.
Insect resistance and risk assessment studies of advanced generations of basmati rice expressing two genes of Bacillus thuringiensis
Advanced generations of different transgenic lines of indica basmati rice (Basmati-370) expressing two unrelated Bt genes, cry1Ac and cry2A were evaluated for resistance to Yellow Stem Borer (YSB)
Genome Editing in Agriculture: Technical and Practical Considerations
Current delivery and regeneration methods are evaluated, their suitability for important crop species is discussed, and the practical aspects of applying the different genome-editing techniques in agriculture are considered.


Gene discovery and product development for grain quality traits.
Genomics-based strategies for gene discovery, coupled with high-throughput transformation processes and miniaturized, automated analytical and functionality assays, have accelerated the identification of product candidates.
Improved phytonutrient content through plant genetic improvement.
The knowledge base on which genetic enhancement may be based is reviewed, gaps in scientific knowledge and technical capacities are identified, and a role for the federal government in research is suggested.
Crop Engineering Goes South
So-called nonprimary crops, often native to the subtropics or tropics, that have untapped potential for producing food, fiber, fuel, and medicines are being studied.
Nutritional genomics: manipulating plant micronutrients to improve human health.
The term "nutritional genomics" is used to describe work at the interface of plant biochemistry, genomics, and human nutrition.
Engineering Plants to Cope With Metals
Metal-resistance genes and enzymes, newly identified in plants and other organisms, could be engineered into crops to help them flourish on metal-rich soils, turning them into a green cleanup crew for heavy metal contamination.
The Plant Revolution
T he initial phase of a revolution in agriculture has already occurred. Large areas of genetically modified (GM) crops of soybeans, corn, cotton, and canola have been successfully grown in the
Biotechnology and food security in the 21st century.
Public investment will be needed, and new and imaginative public-private collaboration can make the gene revolution beneficial to developing countries, which is crucial for the well-being of today's hungry people and future generations.
Worlds apart? The reception of genetically modified foods in Europe and the U.S.
The results of survey research on public perceptions of biotechnology in Europe and the United States during 1996-1997, together with an analysis of press coverage and policy formation from 1984 to 1996, can help to answer this question.
