The two plants share the genome parts, researchers believe, through a process known as “horizontal gene transfer.” Horizontal transfer occurs when genes are passed between organisms without sexual reproduction, as opposed to vertical transfer, in which a parent passes genes to its offspring, As ...
However, horizontal transposon transfer (HTT) is not easily detected, primarily because the complex TE life cycle can generate phylogenetic patterns similar to those expected for HTT events. The increasingly large number of new genome projects, in all branches of life, has provid...
In biology, horizontal gene transfer (HGT) occurs in bacteria, which recombine by transferring part of the DNA from one microbe to another. Similar to linguistic borrowing, this violates the assumptions of tree-based phylogenetics. In phylogenetic models with HGT, a tree still describes the ...
especially when it occurs between phylogenetically distant hosts1,18,19. Most host switches occur via interspecific horizontal transfers (Fig.1:qhi), promoting incongruence in host and symbiont phylogenies20,21,22. In contrast
To test whether transformation-mediated gene transfer occurs in swarm boundaries between different B. subtilis strains, we first tested for swarm boundary formation between all pairwise combinations of six B. subtilis strains isolated from two 1-cm3 soil samples15 and calculated Average Nucleotide Ident...
A key process in the evolution of prokaryotes is the extensive horizontal gene transfer (HGT) that occurs via transformation, transduction, or conjugation (reviewed in [18]). The size of the transferred DNA fragments varies from several hundred nucleotides to segments of many kilobases encompassing ...
medicae showed significant up-regulation in the most Hg-tolerant strain while inside the most Hg-accumulating host-plant. Transfer of a plasmid containing the Mer operon from the most tolerant strain to low-tolerant strains resulted in an immediate increase in Hg tolerance, indicating that the ...
The outward flux of buoyant fluid from beneath the plate occurs primarily in the Ekman layer, while outward flow in the thicker thermal boundary layer is inhibited by a dominant thermal-wind balance. The O(Ra1/2 E3/4 thickness of the thermal boundary layer is determined by a balance between...
Horizontal gene transfer (HGT) is widespread in the evolution of prokaryotes, especially those associated with the human body. Here, we implemented large-scale gene-species phylogenetic tree reconstructions and reconciliations to identify putative HGT-de
Gene transfer from these organelles to the nucleus, often called endosymbiotic gene transfer (EGT), has been studied in many eukaryotic groups27,28,29 and will not be included here. In this study, we identified genes in land plants that were acquired independently from other sources, primarily ...
