CABI Book Chapter Info
Cover for Introduction and the AIGM research project.

As a sequel to a series of workshops organized by the European Science Foundation programme Assessment of the Impacts of Genetically Modified Plants (AIGM), this conference aimed at exploring the ecological and evolutionary effects of the introduction of transgenes into wild relatives of crops, by...

Cover for Hybridization in nature: lessons for the introgression of transgenes into wild relatives.

Many factors determine the chance of transfer of genes from crops to wild relatives: the distance and divergence between them, the extent of gene flow, and the fitness of hybrids. The spectrum of genes that can be transferred to a target species by genetic modification is much wider than that of...

Cover for Hybrids between cultivated and wild carrots: a life history.

Cultivated and wild carrots can hybridize spontaneously, and transgenes may therefore potentially spread from genetically modified carrots into wild populations. This can happen by several different routes. Flowering cultivated carrots may send out pollen to neighbouring populations of wild carrots ...

Cover for Gene exchange between wild and crop in <i xmlns="http://www.w3.org/1999/xhtml">Beta vulgaris</i>: how easy is hybridization and what will happen in later generations?

Four conditions are needed for the introgression of crop genes into wild relatives: (i) pollination is possible; (ii) zygotes are formed (compatibility of pollen and ovules); (iii) F1 hybrids and later hybrid generations are viable and fertile; and (iv) there is no selection against the introduced...

Cover for Hybridization between wheat and wild relatives, a European Union research programme.

This contribution is based mainly on ongoing research in an EU Framework 5 research programme. Wheat is a self-compatible, wind-pollinated species whose flowers are often cleistogamous. Crop to crop gene flow is very limited. Field experiments demonstrate that the distance of wheat pollen dispersal ...

Cover for Molecular genetic assessment of the potential for gene escape in strawberry, a model perennial study crop.

The risk of gene escape from crops to closely related wild species is a major concern, but can be difficult to assess when crop and wild species are genetically similar. Molecular markers with high resolving power can be informative tools for measuring crop-wild gene flow. As a first step towards...

Cover for Asymmetric gene flow and introgression between domesticated and wild populations.

Gene flow may have very different consequences for the structure of the genetic diversity of populations depending on its direction (symmetric versus asymmetric). If gene flow is symmetric between two or more populations, its effect will be the reduction of genetic diversity between the populations ...

Cover for Crop to wild gene flow in rice and its ecological consequences.

Gene flow is the major pathway for transgene escape from crops to their wild relatives (including weedy biotypes). Transgenes that spread to and persist in the environment will probably lead to ecological consequences. Those genes that resist biotic and abiotic stresses could considerably enhance...

Cover for Potential for gene flow from herbicide-resistant GM soybeans to wild soya in the Russian Far East.

We review the potential for related soya species to cross-pollinate in field and greenhouse conditions. Several local soybean cultivars were fertilized successfully by pollen from wild soya. However, when the GM soybean cv. Stine 2254 RR (GTS 40-3-2) was used as a pollen 'donor' and plants of ...

Cover for Introgression from genetically modified plants into wild relatives.

Introgression is the incorporation of a gene from one organism complex into another as a result of hybridization. A major concern with the use of genetically modified (GM) plants is the unintentional spread of the new genes from cultivated plants to their wild relatives and the subsequent impacts...
