Reassortment is the mixing of the genetic material of a species into new combinations in different individuals. Several different processes contribute to reassortment, including assortment of chromosomes, and chromosomal crossover. [1]
Jul 9, 2015 · Reassortment is an evolutionary mechanism of segmented RNA viruses that plays an important but ill-defined role in virus emergence and interspecies transmission. Recent experimental studies have greatly enhanced our understanding of the cellular mechanisms of reassortment within a host cell.
Reassortment is a mechanism available to viruses with segmented genomes (e.g., orthomyxoviruses, reoviruses, and bunyaviruses) allowing generation of novel viruses. Reassortment involves shuffling of complete genome segments.
Sep 13, 2018 · This exchange is a type of recombination called reassortment. Classical recombination involves the joining of nucleic acid sequences derived from two different templates into one chimeric product. During reassortment, however, entire gene segments are swapped to give rise to chimeric genomes.
May 23, 2016 · A shared feature of all segmented RNA viruses is their capacity to exchange genome segments during co-infection by a process called reassortment. Specifically, when two or more viruses infect a...
Jul 4, 2011 · RNA viruses are able to undergo two forms of recombination: RNA recombination, which (in principle) can occur in any type of RNA virus, and reassortment, which is restricted to those viruses with...
Feb 13, 2012 · For segmented viruses, reassortment can introduce drastic genomic and phenotypic changes by allowing a direct exchange of genetic material between coinfecting strains. For instance, multiple influenza pandemics were caused by reassortments of viruses typically found in separate hosts.
Dec 23, 2014 · Reassortment occurs when two or more viruses co-infect a single host cell and exchange discrete RNA segments by means of the packaging of segments from different origins in some progeny viruses. The most characteristic model is antigenic shift in influenza A virus (Nelson et al., 2008).
Jul 9, 2015 · Reassortment is an evolutionary mechanism of segmented RNA viruses that plays an important but ill-defined role in virus emergence and interspecies transmission. Recent experimental studies have greatly enhanced our understanding of the cellular mechanisms of reassortment within a host cell.
Reassortment is a process of genetic recombination that is restricted to segmented RNA viruses and plays a vital role in the evolution of the viruses with pandemic potential in some viruses.
