The plant defensin NaD1, from Nicotiana alata, has potent antifungal activity against a range of filamentous fungi including the two important cotton pathogens, Fusarium oxysporum f. sp. vasinfectum (Fov) and Verticillium dahliae. Transgenic cotton plants expressing NaD1 were produced and plants from three events were selected for further characterization. Homozygous plants were assessed in gre...

tandem with transgenic technology, while also questioning the validity of OCT performance data. Cotton (Gossypium hirsutum L.) cultivars transgenically enhanced A key role of cultivar testing is to provide unbiased to impart herbicide resistance to either bromoxynil [3,5-dibromoagronomic performance in a defined environment while 4-hydroxybenzonitrile; BXN (Bayer Advanced, Peoria, IL)] or glyph...

Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize)...

Abstract Cotton production substantiated a crucial part in the escalating economic development of many countries. To realize increasing global demand for cotton, emphasis should be laid on to improve cotton fiber growth and production. The bioengineered transgenic proved expedient resolving inadequacies conventional but still required improvements encounter heightened textile industries. One po...

Four highly inducible genes of poplar trees, PtdKTI5, PtdWIN4, PtdPOP3 from hybrid poplar (Populus trichocarpa × P. deltoides) and PtKTI2 from trembling aspen (Populus tremuloides Michx.) have been individually transformed into Arabidopsis thaliana for overexpression. High transcriptional level of each transgene in transgenic Arabidopsis lines was confirmed by RT-PCR analysis. The development, ...

Salinity is one of the major environmental factors limiting plant growth and productivity. An H(+)-PPase gene, TsVP from Thellungiella halophila, was transferred into cotton (Gossypium hirsutum) in sense and antisense orientations under control of the cauliflower mosaic virus (CaMV) 35S promoter. Southern and Northern blotting analysis showed that the sense or antisense TsVP were integrated int...

Cotton (Gossypium spp.) fiber cells are seed trichomes derived from the epidermal layer of the cotton seed coat. The molecular components responsible for regulating fiber cell differentiation have not been fully elucidated. A cotton PROTODERMAL FACTOR1 gene (GbPDF1) was found to be expressed preferentially during fiber initiation and early elongation, with highest accumulation in fiber cells 5 ...

The cotton bollworm Helicoverpa armigera is the major insect pest targeted by cotton genetically engineered to produce the Bacillus thuringiensis toxin (transgenic Bt cotton) in the Old World. The evolution of this pest's resistance to B. thuringiensis toxins is the main threat to the long-term effectiveness of transgenic Bt cotton. A deletion mutation allele (r(1)) of a cadherin gene (Ha_BtR) ...

Transgenic Cry1Ac+CpTI cotton (CCRI41) is a promising cotton cultivar throughout China but side effects and especially sublethal effects of this transgenic cultivar on beneficial insects remain poorly studied. More specifically potential sublethal effects on behavioural traits of the honey bee Apis mellifera L. have not been formally assessed despite the importance of honey bees for pollination...
