  1. ...in nematodes (Thomas 2006). These findings suggest that C. nigoni populations are likely to experience some stronger selection pressures such as pathogen exposure compared with C. briggsae, driving the species-specific expansion and evolution of the ubiquitin-ligase-adaptor genes.View larger version...
  2. ...cerevisiae and Schizosaccharomyces pombe , the nematode Caenorhabditis elegans , the fruit fly Drosophila melanogaster , and the green plant Arabidopsis thaliana . A significant fraction of the proteins encoded in each of these s, up to 80% in A. thaliana , belong to LSEs. Many paralogous gene families...
  3. ...positive selection across the studied nematode species. As expected, the majority of genes show genetic drift: 45.3% for Caenorhabditis, 56.4% for Eurhabditis, and 63.2% for Rhabditida (Fig. 5C). As we were mostly interested in signals of positive (adaptive) evolution, we evaluated branch-site models...
  4. ...that plant disease-resistance gene clusters might generate diversity under extreme stress ( Friedman and Baker 2007 ). Here we present evidence that NB-LRR genes, and many others, are particularly prone to have become transposed. In contrast, genes in other gene families, like those encoding most sorts...
  5. ...of indel differences observed among the Bristol, Hawaiian, and Madeiran nematode strains points to the dynamic nature of s and the flux of many of the gene families within this organism. Results Oligonucleotide probe quality and detection of homozygous 50-kb and 1-kb deletions We designed a pilot...
  6. ...plant with a sequenced (Supplemental Fig. S9; Tuskan et al. 2006 ). Among large gene families within A. thaliana ( n > 125) ( Clark et al. 2007 ), variation in PR content was readily apparent ( Fig. 7A,B ; Supplemental Fig. S10). Transcription factors, for which MBML2 SNP data suggested strong...
