Gene flow between crops and their wild relatives
Gene flow from domesticated plants to free-growing relatives was a rather trivial issue before the advent of transgenic crops. Gene flow into crops was relatively more important, especially to plant breeders trying to introduce new genes in a crop, or to breeders and seed growers wanting to ensure the genetic purity of a cultivar. Genes can now be transferred from bacteria, or potentially any p...
متن کاملGene Flow Between Crops and Their Wild Progenitors
Gene flow occurs when there is migration of individuals (e.g., seeds) or gametes (e.g., pollen) between populations. Along with drift, selection, and mutation, it represents one of the main evolutionary forces causing changes in gene frequencies. The main effect of gene flow is the reduction of differentiation between populations accompanied by a parallel increase in differences between individ...
متن کاملDetecting gene flow from GM crops
The likelihood of transgene movement into wild relatives of cultivated crops varies vary dramatically with geography. From the perspective of the UK, crops such as maize lack any close relatives and so effectively cannot act as a source for transgene recruitment into wild plant species. At the other extreme, forage grasses such as Lolium perenne are wind pollinated and have abundant wild popula...
متن کاملGene flow from glyphosate-resistant crops.
Gene flow from transgenic glyphosate-resistant crops can result in the adventitious presence of the transgene, which may negatively impact markets. Gene flow can also produce glyphosate-resistant plants that may interfere with weed management systems. The objective of this article is to review the gene flow literature as it pertains to glyphosate-resistant crops. Gene flow is a natural phenomen...
متن کاملCrops gone wild: evolution of weeds and invasives from domesticated ancestors
The evolution of problematic plants, both weeds and invasives, is a topic of increasing interest. Plants that have evolved from domesticated ancestors have certain advantages for study. Because of their economic importance, domesticated plants are generally well-characterized and readily available for ecogenetic comparison with their wild descendants. Thus, the evolutionary history of crop desc...
