Horizontal gene transfer can be contrasted with vertical gene transfer - the transmission of genetic traits from generation to generation, parent to offspring. Conjugation is how a bacterium can share the information on a plasmid with its neighbors. Bacterial Conjugation Definition. Conjugation is the transfer of a plasmid or other self-transmissible DNA element and sometimes chromosomal DNA from a donor cell to a recipient cell via direct contact usually mediated by a conjugation pilus or sex pilus. Recipients of the DNA transferred by conjugation are called transconjugants. Bacterial Conjugation. Bacterial conjugation is one of the principal means of dissemination of genetic information among microbes and from bacteria to other domains of life including plants and other eukaryotes. From: Encyclopedia of Microbiology (Third Edition), 2009. Related terms: Plasmid; Nested Gene; Bacterium; Conjugation; Mutation; Bacteriophage This is an important gene transfer mechanism in the generation of genomic diversity and bacterial evolution. conjugation in which DNA is transferred between cells via a special tube. Transfer is one-way (from donor to recipient). The donor is referred to as ‘male’, the recipient as ‘female’ and the conjugation tube as a ‘sex pilus Gene Mapping By Using Conjugation. Gene Mapping Using Conjugation the three modes of genetic transfer in the bacterial system; Transformation, Conjugation, and Transduction.Conjugation.In this post (a continuation to Conjugation) we discuss the Interrupted Mating technique and Mapping of genes in bacterial chromosome using the same. Gene transfer: conjugation. Conjugation is a gene transfer process in which a recipient bacterium receives DNA from a donor bacterium by cell-to-cell contact through conjugative pili. Conjugation is mediated by certain plasmids or transposons. Here, we describe plasmid conjugation. Conjugation in bacteria is a process in which plasmids are transferred by themselves alone or along with other DNA element from one cell to another cell through conjugation tube. Conjugation occur by physical contact between cells. The cell which transfer plasmid is called donor and the cell which receive the plasmid is called recipient. Bacterial conjugation is a gene transfer mechanism, first introduced by the scientists named Lederberg and Tatum in the year 1946. The conjugation method was first studied in Escherichia coli.The formation of a conjugation tube is the characteristic feature in a conjugation mechanism. Conjugation. Transfer of DNA from a donor to a recipient by direct physical contact between the cells. In bacteria there are two mating types a donor (male) and a recipient (female) and the direction of transfer of genetic material is one way; DNA is transferred from a donor to a recipient. Mating types in bacteria. Conjugation, the transfer of DNA by direct cell-to-cell contact, depends on the presence of a conjugative plasmid. Plasmids are small, double-stranded DNA molecules that can exist independently of host chromosomes. They have their own replication origins, replicate autonomously, and are stably inherited.
