News Horizontal Gene Transfer

  • Cross species transfer of genes has driven evolution

    Far from just being the product of our parents, University of Adelaide scientists have shown that widespread transfer of genes between species has radically changed the genomes of today's mammals, and been an important driver of evolution. In the world's largest study of so-called "jumping genes", t more

  • Scientists watch bacteria 'harpoon' DNA to speed their evolution

    Indiana University scientists have made the first direct observation of a key step in the process that bacteria use to rapidly evolve new traits, including antibiotic resistance. Using methods invented at IU, researchers recorded the first images of bacterial appendages -- over 10,000 times thinner more

  • Parasitic plants may form weapons out of genes stolen from hosts

    Sneaky parasitic weeds may be able to steal genes from the plants they are attacking and then use those genes against the host plant, according to a team of scientists. In a study, researchers detected 52 incidences of the nonsexual transfer of DNA -- known as horizontal gene transfer, or HGT -- fro more

Horizontal gene transfer

Horizontal gene transfer Horizontal gene transfer (HGT), also Lateral gene transfer (LGT), is any process in which an organism transfers genetic material to another cell that is not its offspring. By contrast, vertical transfer occurs when an ... more
