A metapopulation model for the introgression from genetically modified plants into their wild relatives

摘要: Most models on introgression from genetically modified (GM) plants have focused small spatial scales, modelling gene flow a field containing GM into single adjacent population of wild relative. Here, we present model to study the effect multiple plantations whole metapopulation The most important result is that even very low levels and selection can lead high probability transgene goes fixation in metapopulation. Furthermore, overall frequency metapopulation, after certain number generations introgression, depends dynamics. If there rate migration or turnover, much higher than with lower rates. However, under an island structure, this increased has only transgene. Considering these results, studies potential ecological risks should look not at acting transgene, but also dynamics
