  1. ...is driven by a complex interplay of factors, including selection, recombination, and introgression. The regions determining sexual identity are particularly dynamic parts of eukaryotic genomes that are prone to molecular degeneration associated with suppressed recombination. In the fungus Neurospora...
  2. ...standard procedures ( Sambrook and Russell 2001 ) and rDNA bands were detected using a probe from a conserved region of the LSU derived from S. cerevisiae . Nucleotide diversity Sequences of the polyubiquitin repeat (poly-u repeats) arrays (after removal of introns; monomer ubiquitin sequences were...
  3. ...to the independent underlying mechanisms of mutation compared with other SMs. Approximately 22% of TRMs occurred in microsatellites (defined as tandem repeats with monomers <10 bp), and most of the remainder occurred in satellite DNA. The C. reinhardtii contains many introns featuring tandem repeats (Craig et al...
  4. ...are the most biased, with a 16-fold higher mutation rate in repeats. In Neurospora and several other fungi, CpA dinucleotides are the preferred mutational target of RIP, but in Coccidioides we see a pronounced effect onCpGdinucleotides—a context that has also been reported in other fungi (Galagan and Selker...
  5. ...to ensure that our data set contained only TEs belonging to well-defined, multicopy families (see Methods). Consistent with prior investigations (Wright et al. 2003), 85.7% of the TEs in our data set occupied intergenic regions; i.e., they were not within exons, introns, or untranslated regions (UTRs...

  7. ...evolution includes a neutral component, which is manifest in the positive correlation between the gain and loss rates and a selection-driven component as reflected in the links between intron gain and loss and sequence evolution. The increased intron gain and decreased intron loss in evolutionarily...
  8. ...splicing signals underwent extensive changes during evolution, in parallel with considerable changes in terms of exon-intron architecture and domain structure of the splicing regulators. These changes were presumably shaped by the lifestyle of the organism, selective pressure on maintaining multi-intron...
  9. ...5-6 introns per gene in basidiomycetes such as Cryptococcus neoformans ( Loftus et al. 2005 ), to one to two introns per gene on average for many recently sequenced ascomycetes (e.g., Neurospora, Magnaporthe ) ( Galagan et al. 2003 ; Borkovich et al. 2004 ; Dean et al. 2005 ) to <300 introns...
  10. .... Original annotations for TEs are indicated in parentheses. Promoters include [−1 kb; +100 bp] around the transcription start site; Terminators include [−100 bp; +1 kb] around the transcription termination site; Genes include both exons and introns. MBD1 peaks were shuffled in the to generate a random set...
