Simulating Concerted Evolution
Teshima and Innan, in [1], describes simulation results for duplicated genes under concerted evolution. Their simulation method evolves a pair of initially identical genes; mutations can accumulate in the two genes—under an infinite sites mutation model—causing divergence between the genes, and gene conversions can occur between the two genes, reducing the divergence again. Their method, howeve...
متن کاملConcerted Evolution in the Ribosomal RNA Cistron
BACKGROUND Gene conversion is the mechanism proposed to be responsible for the homogenization of multigene families such as the nuclear ribosomal gene clusters. This concerted evolutionary process prevents individual genes in gene clusters from accumulating mutations. The mechanism responsible for concerted evolution is not well understood but recombination during meiosis has been hypothesized ...
متن کاملGenomic fossils reveal adaptation of non-autonomous pararetroviruses driven by concerted evolution of noncoding regulatory sequences
The interplay of different virus species in a host cell after infection can affect the adaptation of each virus. Endogenous viral elements, such as endogenous pararetroviruses (PRVs), have arisen from vertical inheritance of viral sequences integrated into host germline genomes. As viral genomic fossils, these sequences can thus serve as valuable paleogenomic data to study the long-term evoluti...
متن کاملRapid concerted evolution in animal mitochondrial DNA.
Recombinational genetic processes are thought to be rare in the uniparentally inherited mitochondrial (mt) DNA molecules of vertebrates and other animals. Here, however, we document extremely rapid concerted microevolution, probably mediated by frequent gene conversion events, of duplicated sequences in the mtDNA control region of mangrove killifishes (Kryptolebias marmoratus). In local populat...
متن کاملI-33: Oxidative Stress Responses in EarlyPregnancy
Background: Survival of the conceptus is dependent on continuous progesterone signaling in the maternal decidua but how this is achieved under conditions of oxidative stress that characterize early pregnancy is unknown. Materials and Methods: Laboratory-based analysis of endometrial biopsies and primary endometrial cultures. Results: Using primary cultures, we show that modest levels of reactiv...
