THE POLLINATION OF GENETICALLY MODIFIED PLANTS

Acta Horticulturae, 1991
Genetically modified plants have now been produced in many species. An examination of pollination in these plant will be necessary before commercial cultivars are produced. In addition, this technology provides a new tool for the study of cross-pollination. An initial field trial, using tobacco, was carried out in 1989. Results demonstrated that pollen

Are Genetically Modified Plants Useful and Safe?

IUBMB Life, 2005
AbstractSo far, plants have been genetically modified essentially to achieve resistance to herbicides, or to pathogens (mainly insects, or viruses), but resistance to abiotic stresses (such as cold, heat, drought, or salt) is also being studied. Genetically modified (GM) plants with improved nutritional qualities have more recently been developed, such

Genetically modified plants – the debate continues

Trends in Ecology & Evolution, 2000
The debate about the potential risks and benefits of genetically modified organisms (GMOs) has hit the headlines over the past few months. The polarization of much of the debate obscures what really constitutes ecological risk, and what methods we can apply to identify and quantify those risks.

Environmental impacts of genetically modified plants: A review

Environmental Research, 2017
Powerful scientific techniques have caused dramatic expansion of genetically modified crops leading to altered agricultural practices posing direct and indirect environmental implications. Despite the enhanced yield potential, risks and biosafety concerns associated with such GM crops are the fundamental issues to be addressed.

Genetically Modified Plants and Bees

2011
Genetically modified crops which have opened new avenues of species alteration has been accompanied by concerns of their adverse effects on nontarget organisms such as bees. GM crops are commercially modified for pest and or herbicide resistance. Transgenes such as BT may be expressed in pollen and in the plant parts and secretions collected by bees ...

Breeding with Genetically Modified Plants

2009
Plant breeding aims at the genetic improvement of cultivated plants. Depending on the reproduction system of a plant the breeding process can last up to 15 years for crops and much longer for tree species. The breeding method is determined by the reproductive system of a plant and on the presence of hybrid yield (heterosis).

Genetically modified plants and the precautionary principle

Journal of Risk Research, 2004
The European regulation of genetically modified plants is a particular example of technological risk management that has become an essential part of the management of change. The role of regulators in this management process, when there are demands for regulatory action concerning unquantified (and sometimes unquantifiable) technological risks – with ...
