Gene flow and hybridization in plants are now understood to be significant and variable, impacting invasive species, rare plants, and crops. This has critical implications for the management and monitoring of transgenic crops and their potential spread.
Area of Science:
- Evolutionary Biology
- Plant Sciences
- Genetics
Background:
- Historically, gene flow and hybridization in plants were underestimated.
- Recent research reveals these processes are idiosyncratic and significant.
Purpose of the Study:
- To review the current understanding of plant gene flow and hybridization.
- To discuss the implications of these processes for transgenic crops.
Main Methods:
- Literature review and synthesis of existing data on plant gene flow and hybridization.
Main Results:
- Gene flow occurs at significant rates and distances.
- Hybridization can lead to aggressive invasives and increased extinction risk.
- Transgenes can spread to wild populations, with potentially negative impacts.
Conclusions:
- The variable nature of gene flow complicates management of transgenic crops.
- Intercrop transgene flow warrants further investigation.
- Understanding gene flow is crucial for assessing risks associated with genetically modified organisms.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
