What tangled web: barriers to rampant horizontal gene transfer.
Dawkins in his The Selfish Gene(1) quite aptly applies the term "selfish" to parasitic repetitive DNA sequences endemic to eukaryotic genomes, especially vertebrates. Doolittle and Sapienza(2) as well as Orgel and Crick(3) enlivened this notion of selfish DNA with the identification of such repetitive sequences as remnants of mobile elements such as transposons. In addition, Orgel and Crick(3) ...
متن کاملRampant horizontal gene transfer and phospho-donor change in the evolution of the phosphofructokinase.
Previous work on the evolution of the phosphofructokinase (PFK) has shown that this key regulatory enzyme of glycolysis has undergone an intricate evolutionary history. Here, we have used a comprehensive data set to address the taxonomic distribution of the different types of PFK (ATP-dependent and PPi-dependent ones) and to estimate the frequency of horizontal gene transfer (HGT) events. Numer...
متن کاملMitochondrial DNA of Vitis vinifera and the issue of rampant horizontal gene transfer.
The mitochondrial genome of grape (Vitis vinifera), the largest organelle genome sequenced so far, is presented. The genome is 773,279 nt long and has the highest coding capacity among known angiosperm mitochondrial DNAs (mtDNAs). The proportion of promiscuous DNA of plastid origin in the genome is also the largest ever reported for an angiosperm mtDNA, both in absolute and relative terms. In a...
متن کاملRampant horizontal transfer of SPIN transposons in squamate reptiles.
Transposable elements (TEs) are highly abundant in the genome and capable of mobility, two properties that make them particularly prone to transfer horizontally between organisms. Although the impact of horizontal transfer (HT) of TEs is well recognized in prokaryotes, the frequency of this phenomenon and its contribution to genome evolution in eukaryotes remain poorly appreciated. Here, we pro...
متن کاملRampant polyuridylylation of plastid gene transcripts in the dinoflagellate Lingulodinium
Dinoflagellate plastid genes are believed to be encoded on small generally unigenic plasmid-like minicircles. The minicircle gene complement has reached saturation with an incomplete set of plastid genes (18) compared with typical functional plastids (60-200). While some of the missing plastid genes have recently been found in the nucleus, it is still unknown if additional genes, not located on...
