  1. ncbi request reprint HOM-C evolution in Drosophila: is there a need for Hox gene clustering?
    Barbara Negre
    Departament de Genetica i de Microbiologia, Universitat Autonoma de Barcelona, 08193 Bellaterra Barcelona, Spain
    Trends Genet 23:55-9. 2007
    ..Although there is no evidence of an absolute requirement for Hox gene clustering in Drosophila, we found that strong functional constraints act on the individual genes...
  2. pmc An arthropod cis-regulatory element functioning in sensory organ precursor development dates back to the Cambrian
    Savita Ayyar
    Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK
    BMC Biol 8:127. 2010
    ..First identified in Drosophila, the SOPE contains discrete binding sites for four regulatory factors. The SOPE of the Drosophila asense gene is situated in the 5' UTR...
  3. pmc Fast sequence evolution of Hox and Hox-derived genes in the genus Drosophila
    Sònia Casillas
    Departament de Genetica i de Microbiologia, Universitat Autonoma de Barcelona, 08193 Bellaterra Barcelona, Spain
    BMC Evol Biol 6:106. 2006
    ..However, some observations point to a completely different scenario. Hox genes are usually highly conserved inside the homeobox, but very variable outside it...
  4. pmc Conservation of regulatory sequences and gene expression patterns in the disintegrating Drosophila Hox gene complex
    Barbara Negre
    Departament de Genetica i de Microbiologia, Universitat Autonoma de Barcelona, 08193 Bellaterra, Barcelona, Spain
    Genome Res 15:692-700. 2005
    ..Rather, the organization of Hox genes is modular, and their clustering seems the result of phylogenetic inertia more than functional necessity...
  5. ncbi request reprint A new split of the Hox gene complex in Drosophila: relocation and evolution of the gene labial
    Barbara Negre
    Departament de Genetica i de Microbiologia, Universitat Autonoma de Barcelona, Bellaterra Barcelona Spain
    Mol Biol Evol 20:2042-54. 2003
    ..Seemingly, the relocation of lab has not induced a change in evolution rate or degree of functional constraint. Nevertheless, further work is needed to ascertain whether the lab-pb split has had any effects on gene expression...
  6. pmc The transposon Galileo generates natural chromosomal inversions in Drosophila by ectopic recombination
    Alejandra Delprat
    Departament de Genetica i de Microbiologia, Universitat Autonoma de Barcelona, Bellaterra Barcelona, Spain
    PLoS ONE 4:e7883. 2009
    ..Previous work revealed that the transposon Galileo was involved in the generation of two polymorphic inversions of Drosophila buzzatii...
