Compensated deleterious mutations in insect genomesRob J Kulathinal
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA 02138, USA
Science 306:1553-4. 2004..Surprisingly, the fraction 10% is not affected by phylogenetic distance. These results support a selection-driven process that allows compensated amino acid substitutions to become rapidly fixed in taxa with large populations...
Male sex drive and the masculinization of the genomeRama S Singh
Department of Biology, McMaster University, Hamilton, ON, Canada
Bioessays 27:518-25. 2005..Male sex-drive theory complements the female-choice theory of sexual selection and allows for the genetic variation of costly sexual traits to be continuously replenished...
Rapid evolution of the sex-determining gene, transformer: structural diversity and rate heterogeneity among sibling species of DrosophilaRob J Kulathinal
Department of Biology, McMaster University, Hamilton, Ontario, Canada
Mol Biol Evol 20:441-52. 2003..A comparison of tra orthologs across the genus Drosophila suggest that TRA maintains an assortment of RS domains for proper sex determining function while much of the protein evolves relatively unconstrained...
The nature of genetic variation in sex and reproduction-related genes among sibling species of the Drosophila melanogaster complexRob J Kulathinal
Department of Biology, McMaster University, Hamilton, Ont, Canada L8S 4K1
Genetica 120:245-52. 2004..These results follow a general trend observed in other taxa and demonstrate the preferential involvement of SRR genes in reproductive isolation and species formation...
Evolution in the fast lane: rapidly evolving sex-related genes in DrosophilaWilfried Haerty
Department of Biology, McMaster University, Hamilton, Ontario L8S 4K1, Canada
Genetics 177:1321-35. 2007..SFP genes also show evidence of lineage-specific gene loss and/or gain. These results bring us closer to understanding the details of the evolutionary dynamics of SRR genes with respect to species divergence...
Mammalian sperm proteins are rapidly evolving: evidence of positive selection in functionally diverse genesDara G Torgerson
Department of Biology, McMaster University, Hamilton, Ontario, Canada
Mol Biol Evol 19:1973-80. 2002..These results demonstrate the rapid evolution of sperm-specific genes and highlight the molecular action of sexual selection on a variety of characters involved in mammalian sperm function...
Evolution of genes and genomes on the Drosophila phylogenyAndrew G Clark
Department of Molecular Biology and Genetics, Cornell University, Ithaca, New York 14853, USA
Nature 450:203-18. 2007..These may prove to underlie differences in the ecology and behaviour of these diverse species...
Revisiting the protein-coding gene catalog of Drosophila melanogaster using 12 fly genomesMichael F Lin
Broad Institute of MIT and Harvard, Cambridge, Massachusetts 02139, USA
Genome Res 17:1823-36. 2007..These results affect >10% of annotated fly genes and demonstrate the power of comparative genomics to enhance our understanding of genome organization, even in a model organism as intensively studied as Drosophila melanogaster...
The latest buzz in comparative genomicsRob J Kulathinal
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA 02138, USA
Genome Biol 6:201. 2005..The publication of the Drosophila pseudoobscura sequence provides a snapshot of how genomes have changed over tens of millions of years and sets the stage for the analysis of more fly genomes...
Bayesian analysis suggests that most amino acid replacements in Drosophila are driven by positive selectionStanley A Sawyer
Department of Mathematics, Washington University, St. Louis, MO 63130, USA
J Mol Evol 57:S154-64. 2003..These results are model dependent and we discuss possible modifications of the model that might allow more neutral and nearly neutral amino acid replacements to be fixed...
Fine-scale mapping of recombination rate in Drosophila refines its correlation to diversity and divergenceRob J Kulathinal
Department of Molecular and Cellular Biology, Harvard University, Cambridge, MA 02138, USA
Proc Natl Acad Sci U S A 105:10051-6. 2008..We propose that it is not cross-overs per se that are mutagenic, but rather repair of DNA double-strand break precursors via crossing over and gene conversion...
The functional genomic distribution of protein divergence in two animal phyla: coevolution, genomic conflict, and constraintCristian I Castillo-Davis
Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts 02138, USA
Genome Res 14:802-11. 2004..Thus, strong purifying selection appears to act on the same core cellular processes in both mammalian and nematode lineages, whereas positive and/or relaxed selection acts on different biological processes in each lineage...
