Ecological patterns of genome size variation and the origin of species in salamanders
Bianca Sclavi, John Herrick
Salamanders (urodela) have among the largest vertebrate genomes, ranging in size from 10 to over 80 pg. The urodela are divided into ten extant families each with a characteristic…
Lineage specific reductions in genome size in salamanders are associated with increased rates of mutation
John Herrick, Bianca Sclavi
Very low levels of genetic diversity have been reported in vertebrates with large genomes, notably salamanders and lungfish [1-3]. Interpreting differences in heterozygosity, which…
Slow Evolution of rag1 and pomc Genes in Vertebrates with Large Genomes
Bianca Sclavi, John Herrick
Growing evidence suggests that many vertebrate lineages are evolving at significantly different rates. As a first approximation of evolutionary rates, we assessed the amount of neu…
Gene silencing and large-scale domain structure of the E. coli genome
Mina Zarei, Bianca Sclavi, Marco Cosentino Lagomarsino
The H-NS chromosome-organizing protein in E. coli can stabilize genomic DNA loops, and form oligomeric structures connected to repression of gene expression. Motivated by the link…
DnaA and the timing of chromosome replication in Escherichia coli as a function of growth rate
Matthew A. A. Grant, Chiara Saggioro, Ulisse Ferrari +3
Background: In Escherichia coli, overlapping rounds of DNA replication allow the bacteria to double in faster times than the time required to copy the genome. The precise timing of…
Slow evolution of vertebrates with large genomes
Bianca Sclavi, John Herrick
Darwin introduced the concept of the "living fossil" to describe species belonging to lineages that have experienced little evolutionary change, and suggested that species in more…
Gene clusters reflecting macrodomain structure respond to nucleoid perturbations
Vittore F. Scolari, Bruno Bassetti, Bianca Sclavi +1
Focusing on the DNA-bridging nucleoid proteins Fis and H-NS, and integrating several independent experimental and bioinformatic data sources, we investigate the links between chrom…
