Conjugating bacteria

Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. This takes place through a pilus. It is a parasexual mode of reproduction in bacteria. It is a mechanism of horizontal gene transfer as are transformation and … See more The process was discovered by Joshua Lederberg and Edward Tatum in 1946. See more Conjugation diagram 1. Donor cell produces pilus. 2. Pilus attaches to recipient cell and brings the two cells together. See more Hyperthermophilic archaea encode pili structurally similar to the bacterial conjugative pili. However, unlike in bacteria, where … See more Conjugation is a convenient means for transferring genetic material to a variety of targets. In laboratories, successful transfers have been reported from bacteria to yeast, plants, … See more Conjugation in Mycobacteria smegmatis, like conjugation in E. coli, requires stable and extended contact between a donor and a recipient strain, is DNase resistant, and the transferred … See more Bacteria related to the nitrogen fixing Rhizobia are an interesting case of inter-kingdom conjugation.
