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 کاملQuantifying Gene Flow from Oilseed Rape to Its Wild Relatives
EXTENDED ABSTRACT Gene flow is defined as the movement of genes between populations and is a naturally occurring phenomenon among sexually compatible individuals. Crops have exchanged genes with their wild and weedy relatives for centuries, however this process has recently caused concern. The rapid advances in genetic engineering have hit an immense wall of opposition and gene flow is now seen...
متن کاملTransgenic Crops for Herbicide Resistance
A year after the introduction of the first commercial transgenic crop (Flavr SavrTM tomato with a longer shelf life) in 1994, transgenic, herbicide-resistant crops (HRCs) were introduced (Table 3.1) with the introduction of bromoxynil(3,5dibromo-4-hydroxybenzonitrile) resistant cotton and glufosinate[2-amino-4(hydroxymethylphosphinyl)butanoic acid] resistant canola. Bromoxynil resistance had li...
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 کاملApplication of an atmospheric gene flow model for assessing environmental risks from transgenic corn crops
Gene flow data from experiments under limited environmental conditions (e.g. wind speed and direction, atmospheric stability) have only provided limited information for gene flow risk management. It is necessary to apply models to predict the gene flow under a complete set of possible environmental conditions to inform farmers, seed companies, government agencies, and researchers about the risk...
