Genomic islands: tools of bacterial horizontal gene transfer and evolution [PDF]

, 2017
Bacterial genomes evolve through mutations, rearrangements or horizontal gene transfer. Besides the core genes encoding essential metabolic functions, bacterial genomes also harbour a number of accessory genes acquired by horizontal gene transfer that ...

Ancestral genome estimation reveals the history of ecological diversification in Agrobacterium [PDF]

, 2017
Horizontal gene transfer (HGT) is considered as a major source of innovation in bacteria, and as such is expected to drive adaptation to new ecological niches.

Horizontal gene transfer and bacterial diversity [PDF]

Journal of Biosciences, 2002
Bacterial genomes are extremely dynamic and mosaic in nature. A substantial amount of genetic information is inserted into or deleted from such genomes through the process of horizontal transfer. Through the introduction of novel physiological traits from distantly related organisms, horizontal gene transfer often causes drastic changes in the ...

Bacterial sex in dental plaque [PDF]

, 2013
Genes are transferred between bacteria in dental plaque by transduction, conjugation, and transformation. Membrane vesicles can also provide a mechanism for horizontal gene transfer.

nec1, a Gene Conferring a Necrogenic Phenotype, Is Conserved in Plant-Pathogenic Streptomyces spp. and Linked to a Transposase Pseudogene

Molecular Plant-Microbe Interactions, 1998
We are investigating the genetic basis for, and evolution of, plant pathogenicity in Streptomyces spp. The plant-pathogenic species S. scabies, S. acidiscabies, and S.

Horizontal gene transfer overrides mutation in Escherichia coli colonizing the mammalian gut

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Colonization of the mammalian gut by trillions of commensal bacteria starts early in life and contributes to host health. However, colonization by pathogens can be the launching pad for infection.

Horizontal gene transfer between bacteria [PDF]

Environmental Biosafety Research, 2007
Horizontal gene transfer (HGT) refers to the acquisition of foreign genes by organisms. The occurrence of HGT among bacteria in the environment is assumed to have implications in the risk assessment of genetically modified bacteria which are released into the environment.
