Who discovered horizontal gene transfer?

Mechanisms. There are several mechanisms for horizontal gene transfer: Transformation, the genetic alteration of a cell resulting from the introduction, uptake and expression of foreign genetic material (DNA or RNA). This process is relatively common in bacteria, but less so in eukaryotes.

Horizontal Gene Transfer – an overview | ScienceDirect Topics

Horizontal gene transfer (HGT) is the transfer of genetic material between contemporary organisms. HGT is a common event in prokaryotes (Dagan and Martin, 2007) and, although less likely to occur in complex eukaryotes, was an important aspect of their early evolution and continues to occur in single-celled eukaryotes, such as microalgae.
