Lateral Transfer of the lux Gene Cluster

Journal of Biochemistry, 2006
The lux operon is an uncommon gene cluster. To find the pathway through which the operon has been transferred, we sequenced the operon and both flanking regions in four typical luminous species. In Vibrio cholerae NCIMB 41, a five-gene cluster, most genes of which were highly similar to orthologues present in Gram-positive bacteria, along with the lux ...

Phage as agents of lateral gene transfer

Current Opinion in Microbiology, 2003
When establishing lysogeny, temperate phages integrate their genome as a prophage into the bacterial chromosome. Prophages thus constitute in many bacteria a substantial part of laterally acquired DNA. Some prophages contribute lysogenic conversion genes that are of selective advantage to the bacterial host.

Lateral gene transfer in eukaryotes

Cellular and Molecular Life Sciences, 2005
Lateral gene transfer -- the transfer of genetic material between species -- has been acknowledged as a major mechanism in prokaryotic genome evolution for some time. Recently accumulating data indicate that the process also occurs in the evolution of eukaryotic genomes. However, there are large rate variations between groups of eukaryotes; animals and

Lateral and oblique gene transfer

Current Opinion in Genetics & Development, 2001
Sequence information from complete genomes, and from multiple loci of strains within species, is transforming the way that we investigate the evolution of bacteria. Such large-scale assessments of bacterial genomes have provided evidence of extensive gene transfer and exchange.

TOWARDS IDENTIFYING LATERAL GENE TRANSFER EVENTS [PDF]

Biocomputing 2003, 2002
This paper is concerned with evaluating the performance of the model and algorithm in 5 for detecting lateral gene transfers events. Using a Poisson process to describe arrival times of transfer events, a simulation is used to generate "synthetic" gene and species trees.

Trends and barriers to lateral gene transfer in prokaryotes

Current Opinion in Microbiology, 2011
Gene acquisition by lateral gene transfer (LGT) is an important mechanism for natural variation among prokaryotes. Laboratory experiments show that protein-coding genes can be laterally transferred extremely fast among microbial cells, inherited to most of their descendants, and adapt to a new regulatory regime within a short time.

Lateral Gene Transfer Contributing to Leukemogenesis

Blood, 2015
Abstract The uncontrolled proliferation of genetically mutated cells is the commonly understood mechanism for cancer growth and invasion, with accumulation of new mutations in daughter cells leading to clonal diversity of cancer derived from a single founding event.

Lateral Gene Transfer or Viral Colonization?

Science, 2001
S. L. Salzberg and colleagues reexamined data that had been published by the international human genome sequencing group in which it appeared that between 113 and 223 genes were present in the human genome but were absent from lower eukaryotes ( Caenorhabditis elegans, Saccharomyces cerrevisiae, Drosophila melanogaster, Arabidopsis thaliana ) (Reports,

Lateral gene transfer in phylogeny of azoreductase enzyme

Computational Biology and Chemistry, 2008
This paper attempts to reconstruct the phylogeny of azoreductase enzyme from different organisms and compare it with the small subunit rRNA-based phylogeny of the organisms. The two phylogenies were found to be incongruent, indicating several events of lateral transfer of azoreductase gene between phylogenetically diverse organisms.

Lateral gene transfer and the nature of bacterial innovation

Nature, 2000
Unlike eukaryotes, which evolve principally through the modification of existing genetic information, bacteria have obtained a significant proportion of their genetic diversity through the acquisition of sequences from distantly related organisms.
