The gene flare is referred to in FlyBase by the symbol Dmel\flr (CG10724, FBgn0260049). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: actin binding. There is experimental evidence that it is involved in the biological process: actin filament depolymerization; sarcomere organization; imaginal disc-derived wing hair organization; phagocytosis, engulfment. 20 alleles are reported. The phenotypes of these alleles are annotated with: Z disc; trichome; macrochaeta; microchaeta; socket; wing hair. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: WD40 repeat; WD40-repeat-containing domain; WD40/YVTN repeat-like-containing domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderate expression. Peak expression observed within 00-06 and 12-18 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Many larval and adult organs/tissues expressed at moderate or high levels. Expression at high levels in the following post-embryonic organs or tissues: adult crop, larval midgut, larval hindgut, larval salivary gland, larval carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, larval/adult central nervous system, adult midgut, adult hindgut, larval Malpighian tubules, adult heart, larval fat body, larval trachea, adult ovary, adult male accessory gland, adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1637557_a_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of flr. Gene sequence location is 3L:13405943..13409553.

Phenotypic Description from the Red Book (Lindsley
& Zimm 1992)
Gene/Allele symbols may differ
from current usage
flr: flare
Chaetae and trichomes in thorax and abdomen abnormally shaped. Chaetae have rudimentary sockets, and shaft is
frequently crooked and branched. Trichomes transformed into
multiple short outgrowths which appear as swellings on wing
cells and as rosettes in abdominal cuticle cells. Homozygotes
are zygotic lethals but cell viable; homozygous clones may
have reduced survival in thorax but not in abdomen. Excellent
marker for homozygous 3L clones.

SMART is well suited for the determination of genotoxicity produced by in vivo nitrosation processes and for the study of their modulation by individual compounds or dietary complex mixtures.
The genotoxic effect of the essential oils of O.vulgare, C.capitata and S.thymbra is tested using the SMART assay: the oils do not show any mutagenic or recombinagenic activity.
Sodium azide is tested for somatic mutation and mitotic recombination induction in wing imaginal disc cells using the wing spot test. Sodium azide induces exclusively mitotic recombination in wing somatic cells after chronic exposure. This activity is reduced in the presence of high bioactivation capacity.
The mutagenic and/or carcinogenic activity of electromagnetic fields is estimated using the wing spot test in larvae, exposure causes a statistically significant enhancement of somatic recombination. Supplement of vitamin E suppresses this enhancement.
The genotoxic effects of N-nitroso-N-methylurea (MNU) and acetone oxime (ACOX) are tested using the SMART test. The effect of Hsap\GST on the genotoxic effect is studied: flies carrying three or more copies of Hsap\GST are significantly more resistant to the genotoxic effect of ACOX.
SMART is used to test the genotoxic effect of fullerene C-60: only at the highest possible fullerene concentration a slight genotoxic effect was observed in wing cells.
Assays of a series of compounds in the wing spot test indicates the single mwh spots appear most frequently, followed by less frequent twin spots and then the quite rare flr spots. Some compounds behave in this manner, others do not in that the frequency of single flr spots is equal to or exceeds that of twin spots.
The spectrum of genotoxic events detected by the wing somatic mutation and recombination test (SMART) and the wi eye spot test is different. The wi eye spot test appears not to detect mitotic recombination the way the wing spot test does.
Six alkylating agents have been ranked as follows according to their genotoxic potency in the wing spot test: methyl methanesulfonate > mitomycin C > N-dimethylnitrosamine > chlorambucil ~ monocrotaline > N-diethylnitrosamine.
The genotoxicity of 6 phenazine and aminophenazine derivatives is assayed using the wing spot test in larvae, chemicals exhibit significant mutagenicity.
The relative biological effectiveness of 252Cf neutrons has been determined for two different types of somatic mutations, the wing-spot test (using mwh and flr) and reversion of eye-colour (using w).
Three assays (z-w, wi and wing spot) are used to evaluate the genotoxic response of five chemicals classified as genotoxic non-carcinogens, chemicals significantly increase the frequency of mutant clones.
The wing somatic mutation and recombination test (SMART) of larvae is used to evaluate the genotoxicity of three polycyclic aromatic hydrocarbons (PAHs) and three of their nitro derivatives, genotoxic activity can be detected in somatic cells.
In young larvae only a few but very large spots are induced by application of a mutagen in the wing spot test. In older larvae the frequency is considerably increased but the sizes are smaller. Practically no twin spots (result of mitotic recombination) are found in young or in very old larvae. Results demonstrate the optimal age of the larvae for mutagen treatment is 72 hours.
Ascorbic acid (vitamin C), when used as a pretreatment, protects against mutation/recombination induced by γ rays and chromium (VI) oxide in larvae in the wing spot test.
The attached X and mwh/flr spot test system were used to demonstrate that ginseng and Salvia miltiorrhiza have inhibitory effects on the in vivo mutagenicity induced by N-methyl-N-nitro-N-nitrosoguanidine (MNNG) during spermatogenesis.
The wing spot test has been used to demonstrate that the somatic mutation and recombination test can be used for the genotoxic activity of alcoholic and non-alcoholic beverages.
The adenine derivatives, (R,S)-9-(2,3-dihydroxypropyl)adenine, D-eritadenine and 9-(2-phosphonylmethoxyethyl)adenine, are potent inducers of both single spots and twin spots in a wing-spot assay.
Somatic mutation and recombination test (SMART) is used to determine the relevance of the in vitro effects induced by benzophenone-3: benzophenone-3 is not genotoxic.
Wing-spot assay is used to evaluate the quantitative relationship between BaP-DNA adduct formation, determined by 32P-postlabelling, and the induction of phenotypically mutant cells.
The effect of chlorophyllin on the genotoxicity of chromium(VI) oxide in larvae transheterozygous for mwh and flr is assayed using the wing spot somatic test.
The somatic mutation and recombination test (SMART) in wing cells of three day old larvae transheterozygous for mwh and flr is used to study the mutagenic potential of three benzocphenanthridine alkaloids with antileukemic properties as compared with that of two structurally related aromatic polycyclic hydrocarbons.
The wing spot test is used to evaluate the genotoxicity of the antitumour indenoisoquinoline analogues of nitidine chloride and fagaronine chloride in larvae transheterozygous for mwh and flr, the analogues have a very weak genotoxic effect.
Four antidepressants and one neuroleptic drug are tested for genotoxicity using the somatic mutation and recombination test (SMART) in wing cells of three day old larvae transheterozygous for mwh and flr, the compounds are genotoxic.
Genotoxicity of acrolein is investigated using SMART, SCLT (sex chromosome loss test) and SLRLT (sex linked recessive lethal test). Acrolein is mutagenic in SLRLT when injected but not fed, SCLT does not reveal a clastogenic effect with acrolein and acrolein has a genotoxic effect in SMART.
The mutagenic and recombinogenic activity of 3-beta-hydroxy-13-alpha-amino-13,17-seco-5-alpha-androstan-17-oic-13,17-lactam-p-bis-(2-chloroethyl) aminophenoxyacetate (NSC 294859) has been assayed using a wing somatic mutation and recombination test (SMART).
Wing spot test (SMART) and sex-linked recessive lethal test (SLRLT) are used to test the mutagenicity of sumithion, a broad spectrum insecticide - compound is mutagenic in wing primordial cells and induces recombination at high doses.
SMART in wing cells is used to test genotoxicity of 5 tricyclic antidepressants, results implicate the nitrogen atom at position 5 in the 7-membered ring of the tricyclic molecule as being responsible for the genotoxic property of the compounds.
Genotoxicity of a chelating agent, nitrilotriacetic acid (NTA), is investigated using SMART. NTA is active in inducing mitotic recombination and possible aneuploidy in somatic cells.
The effects of chemicals classified as non-carcinogens or unclassified, but known to have given one or more positive results, are tested using SMART. Also the sensitivity of SMART compared to SLRLT is tested.
Genotoxicity of ethyl carbamate is tested using SMART: ethyl carbamate induces, in a dose-dependent manner, single as well as twin spots, indicating a recombinogenic activity.
The effects of repair deficiency are studied by comparing the frequency of somatic mutation and mitotic recombination in repair proficient female progeny with that in excision repair defective male progeny. Nine chemical mutagens with various modes of action are tested in this way.
The genetic toxicity of six carcinogens and six non-carcinogens are tested using SMART: carcinogens are highly toxic and the non-carcinogens are non-genotoxic.
