Horizontal gene transfer ( HGT) or lateral gene transfer ( LGT) [ 1][ 2][ 3] is the movement of genetic material between organisms other than by the ("vertical") transmission of DNA from parent to offspring ( reproduction ). [ 4] HGT is an important factor in the evolution of many organisms. [ 5][ 6] HGT is influencing scientific understanding ...
Inferring horizontal gene transfer. Horizontal or lateral gene transfer (HGT or LGT) is the transmission of portions of genomic DNA between organisms through a process decoupled from vertical inheritance. In the presence of HGT events, different fragments of the genome are the result of different evolutionary histories.
Horizontal, or lateral, transmission describes the acquisition of a facultative symbiont from the environment or from a nearby host. [2] The life cycle of the host includes both symbiotic and aposymbiotic phases. The aposymbiotic phase generally begins in the germ cells, and during development, the host organism acquires the symbiont and ...
Horizontal gene transfer ( HGT) refers to the transfer of genes between distant branches on the tree of life. In evolution, it can scramble the information needed to reconstruct the phylogeny of organisms, how they are related to one another. HGT can also help scientists to reconstruct and date the tree of life, as a gene transfer can be used ...
Marketing. Horizontal integration is the process of a company increasing production of goods or services at the same level of the value chain, in the same industry. A company may do this via internal expansion or through mergers and acquisitions. [ 1][ 2][ 3] The process can lead to monopoly if a company captures the vast majority of the market ...
The phrase horizontal evolution is used in evolutionary biology to refer to: Concerted evolution, whereby individual members of a DNA family within one species are more closely related to each other than to members of the same type of DNA family in other species; [1] Horizontal gene transfer, where genes are transferred from one organism to ...
Horizontal correlation. Horizontal correlation is a methodology for gene sequence analysis. Rather than referring to one specific technique, horizontal correlation instead encompasses a variety of approaches to sequence analysis that are unified by two specific themes: Sequence analysis is performed by making comparisons horizontally, along the ...
NORWICH, Conn. (AP) — Veteran diplomat Martin S. Indyk, an author and leader at prominent U.S. think tanks who devoted years to finding a path toward peace in the Middle East, died Thursday.
