Lateral transduction is the process by which very long fragments of bacterial DNA are transferred to another bacterium. So far, this form of transduction has been only described in Staphylococcus aureus, but it can transfer more genes and at higher frequencies than generalized and specialized transduction. In lateral transduction, the prophage ...
Genes are transferred via transduction as the prophage genome is imperfectly excised from the host chromosome and integrated into a new host (specialized transduction) or as fragments of host DNA are packaged into the phage particles and introduced into a new host (generalized transduction). [2]
Transduction (machine learning), the process of directly drawing conclusions about new data from previous data, without constructing a model; Transduction (physiology), the transportation of stimuli to the nervous system; Transduction (psychology), reasoning from specific cases to general cases, typically employed by children during their ...
The final result of conjugation, transduction, and/or transformation is the production of genetic recombinants, individuals that carry not only the genes they inherited from their parent cells but also the genes introduced to their genomes by conjugation, transduction, and/or transformation.

A prime example concerning the spread of exotoxins is the adaptive evolution of Shiga toxins in E. coli through horizontal gene transfer via transduction with Shigella species of bacteria. [57] Strategies to combat certain bacterial infections by targeting these specific virulence factors and mobile genetic elements have been proposed. [ 12 ]
Regulation of GTA production and transduction has been best studied in R. capsulatus, where a quorum-sensing system and a CtrA-phosphorelay control expression of not only the main RcGTA gene cluster, but also a holin/endolysin cell lysis system, particle head spikes, an attachment protein (possibly tail fibers), and the capsule and DNA ...
There are three kinds of contextual factors that determine the shape the TGF-β response: the signal transduction components, the transcriptional cofactors and the epigenetic state of the cell. The different ligands and receptors of TGF-β are significant as well in the composition signal transduction pathway. [2]
An overview of major signal transduction pathways. While evolutionarily conserved molecular processes are involved in the cellular mechanisms underlying these switches, in animal species these are very different from the well-characterized gene regulatory mechanisms of bacteria, and even from those of the animals' closest unicellular relatives ...
