Potential Dissemination of Antibiotic Resistance Genes From Transgenic Plants to Microorganisms

Abstract

Evidence that genes were transferred during evolution from plants to bacteria was obtained from nucleotide and protein sequence analyses. However, the extent of such transfers among phylogenetically distant organisms is limited by various factors, including those related to complexity of the environment and those endogenous to the bacteria, designed to prevent a drift of the genome integrity. The goal of this article is to give an overview of the potentials and limits of natural interkingdom gene transfers, with a particular focus on prokaryote originating sequences fitting the nuclear genome of transgenic plants.
