Genome size and intron size in Drosophila.
Petrov, Lozovskaya, and Hartl (1996) demonstrated that unconstrained regions of the non-long terminal repeat retrotransposable element Helena lose DNA at an unusually high rate in species of the Drosophila virilis species group. More recent data also indicate a high rate of DNA loss of Helena in species of the Drosophila melanogaster species subgroup (Petrov and Hartl 1998). Based on these obse...
متن کاملThe mode and tempo of genome size evolution in the subgenus Sophophora
Genome size varies widely across organisms, with no apparent tie to organismal complexity. While genome size is inherited, there is no established evolutionary model for this trait. Hypotheses have been postulated for the observed variation in genome sizes across species, most notably the effective population size hypothesis, the mutational equilibrium hypothesis, and the adaptive hypothesis. W...
متن کاملGenome-size evolution in fishes
Fishes possess both the largest and smallest vertebrate genomes, but the evolutionary significance of this variation is unresolved. The present study provides new genome-size estimates for more than 500 species, with a focus on the cartilaginous and ray-finned fishes. These results confirm that genomes are smaller in ray-finned than in cartilaginous fishes, with the exception of polyploids, whi...

15 صفحه اولEvolution of genome base composition and genome size in bacteria
In bacteria and archaea, genome size and guanine–cytosine (GC) content are correlated (Bentley and Parkhill, 2004; Musto et al., 2006; Mitchell, 2007; Suzuki et al., 2008; Guo et al., 2009). These parameters show greater correlation in bacteria (Pearson’s correlation coefficient r = 0.46) than in archaea (r = 0.195) (Nishida, 2012a). The GC content in bacteria varies widely from 13.5% in “Candi...
