Immigrans Species Group
The ''Drosophila immigrans'' species group is a polyphyletic and speciose lineage of ''Drosophila'' flies, including over 100 species. Immigrans species belong to the Immigrans-tripunctata radiation of the subgenus Drosophila. Well-described species include ''Drosophila immigrans'', and the sister species ''Drosophila albomicans'' and ''Drosophila nasuta''. The genome of ''D. albomicans'' was sequenced in 2012 in an effort to characterize novel sex chromosome development in ''D. albomicans''. Immigrans group species are related to mushroom-breeding Drosophila of the Quinaria A quinaria (plural: quinariae) is a Roman unit of area, roughly equal to . Its primary use was to measure the cross-sectional area of pipes in Roman water distribution systems. A "one quinaria" pipe is in diameter.

Vinegar Fly
''Drosophila melanogaster'' is a species of fly (the taxonomic order Diptera) in the family Drosophilidae. The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the "vinegar fly" or "pomace fly". Starting with Charles W. Woodworth's 1901 proposal of the use of this species as a model organism, ''D. melanogaster'' continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution. As of 2017, five Nobel Prizes have been awarded to drosophilists for their work using the insect. ''D. melanogaster'' is typically used in research owing to its rapid life cycle, relatively simple genetics with only four pairs of chromosomes, and large number of offspring per generation. It was originally an African species, with all non-African lineages having a common origin. Its geographic range includes all continents, including islands. ''D. melanogaster'' is a common pest in homes, restaurants, and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosophilidae
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. Another distantly related family of flies, Tephritidae, are true fruit flies because they are frugivorous, and include apple maggot flies and many pests. The best known species of the Drosophilidae is ''Drosophila melanogaster'', within the genus ''Drosophila'', also called the "fruit fly." ''Drosophila melanogaster'' is used extensively for studies concerning genetics, development, physiology, ecology and behaviour. Many fundamental biological mechanisms were discovered first in ''D. melanogaster.'' The fruit fly is mostly composed of post-mitotic cells, has a very short lifespan, and shows gradual aging. As in other species, temperature influences the life history of the animal. Several genes have been identified that can be manipulated to extend the lifespan of these insects. Additionally, ''Drosophi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immigrans-tripunctata Radiation
The immigrans-tripunctata radiation is a speciose lineage of ''Drosophila'' flies, including over 300 species. The immigrans-tripunctata radiation is a sister lineage to most other members of the subgenus Drosophila. A number of species have had their genomes or transcriptomes sequenced for evolutionary studies using ''Drosophila''. Species groups The following species groups and numbers largely derive from O'Grady (2018). * Immigrans species group (106 species) * Tripunctata species group (83 species) * Quinaria species group (35 species) * Guarani species group (24 species) * Cardini species group (16 species) * Calloptera species group (8 species) * Bizonata species group (7 species) * Funebris species group (7 species) * Testacea species group (4 species) Sequenced genomes or transcriptomes The following species have extensive genetic sequence data available.

Drosophila (subgenus)
''Drosophila'' is a paraphyletic subgenus of the genus ''Drosophila'', a classification of fruit flies. This subgenus was first described by Alfred Sturtevant in 1939.Sturtevant, A. H. (1939)On the subdivision of the genus ''Drosophila'' ''Proceedings of the National Academy of Sciences of the United States of America''. 25, 137–141. Members of the subgenus Drosophila can be distinguished from other Drosophilid species by breaks in the pigmentation along the dorsal section of their abdomen. Phylogeny Most species are within three major groups, the ''virilis-repleta'' radiation, the ''immigrans-tripunctata'' radiation and the Hawaiian Drosophila. Additionally, several smaller species groups are recognized consisting of smaller numbers of species, like the ''tumiditarsus'' species group and the ''polychaeta'' species group.

Drosophila Quinaria Species Group
The ''Drosophila quinaria'' species group is a speciose lineage of mushroom-feeding flies studied for their specialist ecology, their parasites, population genetics, and the evolution of immune systems. Quinaria species are part of the Drosophila subgenus. Mushroom-feeding ecology Quinaria group species are commonly found on wild mushrooms, and can metabolize toxic compounds in ''Amanita'' mushrooms, such as ibotenic acid and alpha-amanitin. Mushroom sites also host a number of natural enemies. For instance, as a consequence of their mushroom-feeding ecology, Quinaria species are frequently infected by nematodes of the genus '' Howardula''. Some Quinaria species are more or less susceptible to nematode parasitization, though the immunological reasons remain unclear. One possibility to explain this variance is differences in defensive bacterial symbionts. However another could be natural resource use, as most eukaryotes are unable to withstand the toxins in ''Amanita'' mushroo ...

Drosophila Testacea Species Group
The ''Drosophila testacea'' species group belongs to the Immigrans-tripunctata radiation of the subgenus Drosophila, and contains 4 species: '' Drosophila putrida'', ''Drosophila neotestacea'', ''Drosophila testacea'', and '' Drosophila orientacea''.Grimaldi, James, and Jaenike. 1992. Systematics and Modes of Reproductive Isolation in the Holarctic Drosophila testacea Species Group (Diptera: Drosophilidae). https://academic.oup.com/aesa/article/85/6/671/2759036 Testacea species are specialist mushroom-feeding flies, and can metabolize toxic compounds in ''Amanita'' mushrooms. The Testacea species group is studied for its specialist ecology, population genetics, and bacterial endosymbionts. The North American species ''Drosophila neotestacea'' is perhaps the best-studied of the group for its interactions with parasitic wasps and nematodes, bacterial endosymbionts, and trypanosomatid parasites. Of note, selfish X chromosomes (a form of meiotic drive) have been discovered in three o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosophila Albomicans
''Drosophila albomicans'' is a species of vinegar fly in the family Drosophilidae. ''Drosophila albomicans'' is a member of the Immigrans-tripunctata radiation of the subgenus Drosophila. The ''D. albomicans'' genome was first sequenced in 2012 to study the evolution of novel sex chromosomes, a characteristic this species is best known for. One commonly accepted definition of the biological species concept is that individuals or populations are members of different species if they are incapable of successful interbreeding. While ''D. albomicans'' and ''Drosophila nasuta'' are commonly referred to as distinct species, there appears to be little to no sexual isolation between these two ''Drosophila'' species. Instead, behavioural differences appear to reproductively isolate these two species. The Immigrans species group (to which ''D. albomicans'' belongs) is related to the ''Drosophila quinaria'' and ''Drosophila testacea'' species groups. The related species ''Drosophila immigr ...

Drosophila
''Drosophila'' () is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of ''Drosophila'' in particular, ''D. melanogaster'', has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "''Drosophila''" are often used synonymously with ''D. melanogaster'' in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appearance, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
