Learn about the difference between vertical gene transfer & horizontal gene transfer. Understand the artificial and natural mechanisms of lateral...
Horizontal gene transfer (HGT) is now widely accepted as an indispensable mechanism in the evolution of microbes, but its contribution in metazoans still raises controversies. This is partly due to the methodologies used for the comprehensive prediction of HGT candidates from genomic information and ...
While horizontal gene transfer has been shown to occur naturally in nature (between plants that grow close to each other), various artificial techniques are used to insert gene sequences to some plants with the aim of increasing yields, making them more tolerant of various environmental conditions...
The overall structure of membranes forms a lipid monolayer which is much more heat resistant than the lipid bilayer of mesophilic organisms. c. Gene transfer DNA transfer is a vital part o several hyperthermophilic organisms in order to survive extremely high temperatures. Horizontal gene transfer tak...
Prokaryotic gene evolution occurs either by horizontal gene transfer, mutation, or sexual reproduction in sexually reproducing species as bacteria. Some prokaryotes acquire new genes by the process of conjugation where the plasmid of a prokaryote is introduced into another to transfer new genes to it,...
The main way in which viruses in soils act beneficially is by transferring genes between microbial hosts by horizontal gene transfer. The gene transfer enables the transfer of beneficial characteristics between different communities. Another way that viruses in soils have potential benefits for plants is...

Unicellular organisms emerged over 3 billion years ago where horizontal gene transfer occurred between different species that finally led to the formation of three different cell types. This theory was proposed after the analysis of the three cells’ genomes and obtaining results showing that they shar...
The analyzed organisms included eukaryotes and in particular fungi; horizontal gene transfer events are very rare in these organisms. Thus, the methods used for inferring the ancestral families of orthologs, which assume only gene deletions and duplications, should reliable. ...
Viral virulence factors, for instance, are chieflyproteinsthat are incited by the infective virus to be produced by the host’s ownproteinmachinery. Bacterial virulence factors are likewise proteins that are coded for by their owngenesor byplasmidsthat they acquired via horizontalgene transfer. ...
