GC-content evolution in mammalian genomes: the biased gene conversion hypothesis.
BASE composition is spatially structured in mammaisochores may simply reflect variable mutation processes among genomic regions, consistent with the neutral lian genomes. From sodium chloride centrifugation experiments, Bernardi et al. (1985) defined three model. Such variation in mutational biases has never been demonstrated. Alternatively, isochores might be major classes of genomic fragments...

متن کاملBiased Gene Conversion and GC-Content Evolution in the Coding Sequences of Reptiles and Vertebrates
Mammalian and avian genomes are characterized by a substantial spatial heterogeneity of GC-content, which is often interpreted as reflecting the effect of local GC-biased gene conversion (gBGC), a meiotic repair bias that favors G and C over A and T alleles in high-recombining genomic regions. Surprisingly, the first fully sequenced nonavian sauropsid (i.e., reptile), the green anole Anolis car...
متن کاملGC-Content Evolution in Bacterial Genomes: The Biased Gene Conversion Hypothesis Expands
The characterization of functional elements in genomes relies on the identification of the footprints of natural selection. In this quest, taking into account neutral evolutionary processes such as mutation and genetic drift is crucial because these forces can generate patterns that may obscure or mimic signatures of selection. In mammals, and probably in many eukaryotes, another such confoundi...
متن کاملMutational Biases and GC-Biased Gene Conversion Affect GC Content in the Plastomes of Dendrobium Genus
The variation of GC content is a key genome feature because it is associated with fundamental elements of genome organization. However, the reason for this variation is still an open question. Different kinds of hypotheses have been proposed to explain the variation of GC content during genome evolution. However, these hypotheses have not been explicitly investigated in whole plastome sequences...
