Although theory has demonstrated rather low levels of gene flow are sufficient to counteract
opposing mutation, drift, and selection, widespread recognition of the evolutionary …

Plant evolutionary biologists' view of gene flow and hybridization has undergone a
revolution. Twenty–five years ago, both were considered rare and largely inconsequential …

Publisher Summary This chapter discusses the gene flow and introgression from
domesticated plants into their wild relatives. Domesticated plants cannot be regarded as …

Development of herbicide-resistant crops has resulted in significant changes to agronomic
practices, one of which is the adoption of effective, simple, low-risk, crop-production systems …

In Alien Species and Evolution, biologist George W. Cox reviews and synthesizes emerging
information on the evolutionary changes that occur in plants, animals, and microbial …

During the past decade there has been a tremendous resurgence of interest in polyploidy
that has in large part been stimulated by the development of increasingly powerful genetic …

With the advent of genetic engineering, designer crops might interbreed with natural
populations. Could such romances lead to the evolution of superweeds, as some have …

I niques, plant breeders now have access to an astounding number of useful genes that can
be in-serted into the plant genome. Virtu-ally all commercially important plants are being …

It is hard to ignore the ongoing, often emotional, public discussion of the impacts of the
products of crop biotechnology. At one extreme of the hype is self-rightoeus panic, and at the …

Whether new combinations of genes that result from hybridization and introgression
between wild and cultivated taxa are maintained, with the resultant development of …
