High impact information on Drosophilidae

• The complete genomic organization of the Drosophila troponin T (TnT) gene shows many interesting features, including the presence of a microexon of only 3 nucleotides conserved among Drosophilidae [1].
• From examination of the central axonal projections of sensory bristles on the notum of several species of Drosophilidae, we demonstrate different features that may indicate different functions for macro- and microchaetes [2].
• To explain this unexpected finding, it is proposed that the ADH: genes of the family Drosophilidae may not be orthologous to the ADH: genes of the other two families, Tephritidae and Sarcophagidae [3].
• The codon bias of the Adh gene of D. funebris is among the lowest reported for any Adh gene in the Drosophilidae species and is very similar to that of the Adhr gene [4].
• The region of the clock gene period (per) that encodes a repetitive tract of threonine-glycine (Thr-Gly) pairs has been compared between Dipteran species both within and outside the Drosophilidae [5].

Biological context of Drosophilidae

• The accelerated evolution in the repetitive region of the Drosophilidae appears to be mainly due to an expansion of two ancestral repeats, one encoding a Thr-Gly dipeptide and the other a pentapeptide rich in serine, glycine, and asparagine or threonine [5].
• Sequences from the nuclear (nu) alcohol dehydrogenase gene, the nu 28S ribosomal RNA locus, and the mitochondrial cytochrome oxidase II gene were used both individually and in combined analyses to infer the phylogeny of the subgenus Sophophora (Diptera: Drosophilidae) [6].

Associations of Drosophilidae with chemical compounds

• We subjected at least 41 Drosophilidae taxa to a phylogenetic analysis using a 516-base pair (bp) fragment of the alpha-methyldopa (Amd) nuclear gene and a 672 bp fragment of the mitochondrial cytochrome oxidase subunit II (COII) gene both individually and in combination [7].
• Survey of malathion resistance and avermectin susceptibility in field populations of Drosophila melanogaster (Diptera: Drosophilidae) and D. simulans [8].

Gene context of Drosophilidae

• Cytochrome P-450 field insecticide tolerance and development of laboratory resistance in grape vine populations of Drosophila melanogaster (Diptera: Drosophilidae) [9].
• The TpnC gene complement is five genes in Drosophilidae as previously reported for D. melanogaster [10].
• Evolution of the AMP-forming acetyl-CoA synthetase gene in the Drosophilidae family [11].
• We analyzed the phylogenetic relationship between the species of Lordiphosa and other Drosophilidae using alcohol dehydrogenase (Adh) gene sequences [12].
• Unexpectedly, several species within the dipteran family Drosophilidae were found to contain two differently sized 4f-rnp gene sequence variants, owing to precise in-frame intron losses [13].
