Abstract: Several recent analyses have used quartet-based methods to assess the congruence among phylogenies derived for large sets of genes from prokaryotic genomes. The principal conclusion from these studies is that lateral gene transfer (LGT) has blurred prokaryotic phylogenies to such a degree that the darwinian scheme of treelike evolution might be abandoned in favor …
Text: The realization that horizontal (lateral) gene transfer (HGT) might have had a major impact on biological evolution is perhaps the most fundamental change in our perception of general aspects of biology brought about by massive genome sequencing (Gogarten et al., 2002; Doolittle et al., 2003). As Lawrence and Hendrickson (2003) rightly point out in …
Abstract: Horizontal gene transfer (HGT) enables bacteria to access, share, and recombine genetic variation, resulting in genetic diversity that cannot be obtained through mutational processes alone. In most cases, the observation of evolutionary successful HGT events relies on the outcome of initially rare events that lead to novel functions in the new host, and that …
Abstract: In recent years, corn crop is produced extensively as first and second product in Kahramanmaraş the pests formed European corn borer (Ostrinia nubilalis Hübner) and the stem corn borer (Sesamia nonagrioides Lef.), causes the loss of product per year, average 10-20 % rate. In particularly, this crop loss is observed from the fields which …
Abstract: T-DNA insertion mutants have become a valuable resource for studies of gene function in Arabidopsis. In the course of both forward and reverse genetic projects, we have identified novel interchromosomal rearrangements in two Arabidopsis T-DNA insertion lines. Both rearrangements were unilateral translocations associated with the left borders of T-DNA inserts that exhibited normal Mendelian …
Abstract: This paper provides an overview of the effects of transgenic plants, also known as Genetically Modified Organisms, and food safety. Modern biotechnologies are powerfull tools in reprogramming life. However, a major problem in the risk assessment of the organisms produced by biotechnology is that the outcome of transformations can not be fully foreseen. Potential …
