“…More extensive taxon sampling will be required before this can be tested rigorously. Previous studies based on morphology (Bock and Wheeler, 1972), polytene chromosome banding patterns (Ashburner et al, 1984), and nucleotide sequences (Goto and Kimura, 2001) support the notion that the ananassae and montium species groups diverged from the other subgroups early in the evolution of the melanogaster species group. Both the previous studies and our 451 analyses suggest three clades, (1) ananassae, (2) montium, and (3) suzukii-takahashii-ficusphila-melanogaster-eugracilis.…”

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). We used several optimality criteria, including maximum likelihood, maximum parsimony, and minimum evolution, to analyze these partitions to test the monophyly of the subgenus Sophophora and its four largest species groups, melanogaster, obscura, saltans, and willistoni. Our results suggest that the melanogaster and obscura species groups are each monophyletic and form a closely related clade. The Neotropical clade, containing the saltans and willistoni species groups, is also recovered, as previous studies have suggested. While the saltans species group is strongly supported as monophyletic, the results of several analyses indicate that the willistoni species group may be paraphyletic with respect to the saltans species group.

“…Some studies have analyzed their phylogenies of melanogaster species group from morphology (Bock & Wheeler, 1972), biogeography (Throckmorton, 1975;Lemeunier, David & Tsacas, 1986), chromosomal data (Ashburner, Bodmer & Lemeunier, 1984), and molecular evidences (Pe´landakis & Solignac, 1993;Inomata, Tachida & Yamazaki, 1997;Goto, Kitamura & Kimura, 2000;Harr, Zangerl & Schlotterer, 2000;Schawaroch, 2000;Kopp & True, 2002). In this study, we constructed a phylogenetic tree about subgroup species of Drosophila melanogaster species group based on the Dfak TyK domains and the intron loss (Figure 3a).…”

Intron loss and its evolutionary significance have been noted in Drosophila. The current study provides another example of intron loss within a single-copy Dfak gene in Drosophila. By using polymerase chain reaction (PCR), we amplified about 1.3 kb fragment spanning intron 5-10, located in the position of Tyr kinase (TyK) domain of Dfak gene from Drosophila melanogaster species group, and observed size difference among the amplified DNA fragments from different species. Further sequencing analysis revealed that D. melanogaster and D. simulans deleted an about 60 bp of DNA fragment relative to other 7 Drosophila species, such as D. elegans, D. ficusphila, D. biarmipes, D. takahashii, D. jambulina, D. prostipennis and D. pseudoobscura, and the deleted fragment located precisely in the position of one intron. The data suggested that intron loss might have occurred in the Dfak gene evolutionary process of D. melanogaster and D. simulans of Drosophila melanogaster species group. In addition, the constructed phylogenetic tree based on the Dfak TyK domains clearly revealed the evolutionary relationships between subgroups of Drosophila melanogaster species group, and the intron loss identified from D. melanogaster and D. simulans provides a unique diagnostic tool for taxonomic classification of the melanogaster subgroup from other group of genus Drosophila.

“…D. simulans and D. melanogaster are closely related members of the melanogaster species group, having diverged $2.5-4 million years ago (MYA) (Ashburner et al 1984;Cariou 1987). In contrast, the last shared ancestor for D. virilis and D. melanogaster is thought to have lived $65-70 MYA during the late Cretaceous period (Beverley and Wilson 1984;Cariou 1987).…”

Exploratory Activity in Drosophila Requires thekurtzNonvisual Arrestin

When Drosophila adults are placed into an open field arena, they initially exhibit an elevated level of activity followed by a reduced stable level of spontaneous activity. We have found that the initial elevated component arises from the fly's interaction with the novel arena since: (1) the increased activity is independent of handling prior to placement within the arena, (2) the fly's elevated activity is proportional to the size of the arena, and (3) the decay in activity to spontaneous levels requires both visual and olfactory input. These data indicate that active exploration is the major component of elevated initial activity. There is a specific requirement for the kurtz nonvisual arrestin in the nervous system for both the exploration stimulated by the novel arena and the mechanically stimulated activity. kurtz is not required for spontaneous activity; kurtz mutants display normal levels of spontaneous activity and average the same velocities as wild-type controls. Inhibition of dopamine signaling has no effect on the elevated initial activity phase in either wild-type or krz 1 mutants. Therefore, the exploratory phase of open field activity requires kurtz in the nervous system, but is independent of dopamine's stimulation of activity.
