Horizontal gene transfer HGT or lateral gene transfer LGT is the movement of genetic material between unicellular and or multicellular organisms other than by the “vertical” transmission of DNA from parent to offspring. HGT is an important factor in the evolution of many organisms..Acquisition of DNA through horizontal gene transfer is distinguished from the transmission of genetic material from parents to offspring during reproduction, which is known as vertical gene transfer. In transformation, prokaryotes take up free fragments of DNA, often in the form of plasmids, found in their environment..Horizontal gene transfer may occur via three main mechanisms transformation, transduction or conjugation. Transformation involves uptake of short fragments of naked DNA by naturally transformable bacteria.
