Localization of PPP genes in Muller elements of 12 Drosophila species.

aAccording to Cohen [65].bThe gene names are given according to Flybase (http://flybase.org/) and are followed by frequently used synonyms. The names of the genes that constitute the minimal PPP toolkit are written in bold face.cSpecies names are abbreviated as follows: Dmel: D. melanogaster, Dsim: D. simulans, Dsec: D. sechellia, Dyak: D. yakuba, Dere: D. erecta, Dana: D. ananassae, Dpse: D. pseudoobscura, Dper: D. persimilis, Dwil: D. willistoni, Dmoj: D. mojevensis, Dvir: D. virilis, Dgri: D. grimshawi.dThe correct chromosomal localization of a gene is given in parentheses if different from the position inferred from the gene name.These gene sequences wereeidentified,frevised, orgconfirmed by PCR and DNA sequencing.hThe gene size was confirmed by PCR.iThe gene localization was corrected on the bases of genome environment.x stands for a lost/missing gene.The localization of intronless genes is highlighted in underlined italics.
