FlyBase Allele Report: Dmel\Mad[12]

Mad¹²/Mad^k00237 transheterozygotes show a significant reduction in the number of synaptic boutons at the third instar larval neuromuscular junction, as compared to controls.

(Banerjee et al., 2017)

Mad¹²/+ third instar larvae have similar numbers of boutons to wild type.

(Li et al., 2016)

Mad¹² mutant nuclei are small and tightly packed, unlike wild-type copper cell nuclei, which are polyploid and regularly spaced.

Eight days after induction of intestinal stem cell (ISC) clones, the number of cells in Mad¹² mutant clones is significantly higher than in wild-type clones. After injury by feeding bleomycin, mutant clones have more cells than both wild-type clones and mutant clones before injury.

Wild-type clones contain one stem cell, whereas approximately one-third of Mad¹² mutant clones show a gradual increase in ISC number over time.

One-stem-cell Mad¹² mutant clones contain more stem cells than wild-type clones, indicating that mutant ISCs divide more often than wild-type ones.

(Guo et al., 2013)

Heterozygotes climb sightly, but significantly, better than wild-type controls in a negative geotaxis assay.

(Goldstein et al., 2011)

Very few Mad¹² mutant wing disc clones are recovered.

(Oh and Irvine, 2011)

Mad¹²/Mad⁷ mutant third instar larvae show increased uptake and transport of ingested fluorescently labeled fatty acids from the midgut lumen to the fat body compared to wild-type controls.

(Ballard et al., 2010)

Clones of Mad¹²-mutant cells cause premature differentiation of the adult midgut precursor cells into large, polyploid, enterocyte-like cells compared with wild-type cells.

(Mathur et al., 2010)

Somatic clones of Mad¹² homozygous cells in the developing retina at 42 hours APF have abnormal arrangements of inter-ommatidial cells including aberrant bristle-bristle contacts and abberant arrangements of secondary and tertiary pigment cells.

(Cordero et al., 2007)

Homozygous cells in the morphogenetic furrow (in clones that encompass the morphogenetic furrow) can stil achieve proper apicobasal contraction.

(Corrigall et al., 2007)

Mad¹² mutant germline stem cells (GSCs) show maintenance and cell division defects when clones are generated during adult stages. However no defects are seen when Mad¹² clones are generated during the larval and pupal stages.

(Shcherbata et al., 2007)

Mosaic female germaria containing germline stem cells in contact only with homozygous somatic cap cells do not show any defects in germline stem cell renewal.

(Bolivar et al., 2006)

G1 arrest is delayed in Mad¹² eye disc cells; some mutant cells don't arrest at all in larger Mad¹² clones.

(Firth and Baker, 2005)

Homozygous clones in the wing disc extrude from the wing epithelium.

(Gibson and Perrimon, 2005)

When neutral marked clones are induced in the ovary, the proportion of germaria carrying marked somatic stem cells 3 weeks after clone induction is around 70% of that seen one week after clone induction. For Mad¹² homozygous clones, the equivalent figure is under 25%, resulting in significantly fewer clones in the follicle cells.

(Kirilly et al., 2005)

Mad¹¹/Mad¹² transheterozygotes exhibit abnormal L4/L5 wing veins, with no L2 or crossveins and a large margin notch.

(Takaesu et al., 2005)

Clones of male Mad¹² homozygous germline stem cells are still present in less than 1% of testes one week after clone induction and none are present two weeks after clone induction. This is in contrast to wild-type control clones, which are present in 82% of testes one week after clone induction and 64% two weeks after clone induction.

(Kawase et al., 2004)

The evoked excitatory junctional potential (EJP) (measured at muscle 6 of segment A3) shows a decrease in amplitude in Mad¹/Mad¹² animals compared to wild type. Quantal content is reduced compared to wild type.

(McCabe et al., 2004)

The average number of crystal cells per embryo is significantly reduced in homozygous stage 13-14 embryos compared to wild type.

(Milchanowski et al., 2004)

Ovarioles carrying Mad¹² GSC clones are not recovered, but ovarioles with mutant Mad¹² germ cells in egg chambers are recovered, indicating that Mad¹² GSCs can not be maintained before adulthood.

(Zhu and Xie, 2003)

Homozygous clones induced before 72 hours after egg laying (AEL) show elimination of entire tarsal segments, whereas if clones are induced after 84 hours AEL, only dorsal leg pattern features are affected.

(Galindo et al., 2002)

In somatic clones induced late in the third larval instar L3 bifurcates or terminates at the clone boundary. L2 was seen to loop round a small clone. In 50 clones, all were seen to disrupt vein formation in a cell autonomous manner.

(Marquez et al., 2001)

When somatic clones are created in the glial cells of the developing eye, they contain fewer cells than equivalent wild-type clones. the total number glial cells remains the same as wild-type cells appear to compensate for the loss of mutant ones.

(Rangarajan et al., 2001)

Encapsulation defects of 16-cell cysts are seen in ovaries containing homozygous follicle cell clones.

(Jordan et al., 2000)

Clones induced in the pleura showed a sternite or tergite identity rarely - 6 cases out of several hundred clones. Other clones retain a pleural identity or display a weak phenotype such as mild sclerotinization. Clones at or near the dorsal midline show loss of tergal pigmentation. A partial loss of pigmentation is often observed in clones lateral to the anterior inflection of the pigment band.

(Kopp et al., 1999)

20% of the dorsal branch fusion events are disrupted. The fusion cell extends a sprout but does not contact the appropriate fusion partner.

(Steneberg et al., 1999)

Gastric caecae frequently fail to elongate. Dorsal trunk and visceral branches of the developing trachea are essentially normal. Branching defects occur, ganglionic branches fail to fuse. Dorsal trunk is normal.

(Waltzer and Bienz, 1999)

Embryos lacking maternal and zygotic Mad function (Mad¹⁰/Mad¹² embryos derived from females with homozygous Mad¹² germ line clones) show loss of dorsal tissue and expansion of the lateral denticle bands into dorsal regions. The phenotype is partially paternally rescuable.

(Das et al., 1998)

Mad^Ez/Mad¹² flies have imaginal disc defects. All the progeny of Mad^Ez/Mad¹² females mated to wild-type males die as embryos. One-half of the embryos (presumptive genotype Mad¹²/+ have a weakly ventralised phenotype, and the other half (presumptive genotype Mad^Ez/+) have a variably expressive dorsal-open phenotype.

(Hudson et al., 1998)

Females with homozygous germ line clones lay very few eggs, all of which are unfertilised and smaller than normal. The ovaries of these females may contain no discernible ovarioles or may contain many degenerating egg chambers, the most mature of which are at stage 10.

(Wisotzkey et al., 1998)

Clonal analysis in the germarium reveals that mutant stem cells are lost more rapidly than wild type, though there is no effect on the formation of 16 cell cysts or their subsequent development. Stem cell half life is 0.25 weeks (wild type being 4.6 weeks). Stem cell division rate relative to control is 0.21. Cysts contain the normal 16 cells, including and oocyte.

(Xie and Spradling, 1998)

Clonal analysis revealed that Mad function is autonomously required in the eye imaginal disc cells for proliferation and/or survival.

(Wiersdorff et al., 1996)

Heterozygotes with Df(2L)C28 die as prepupae.

(Raftery et al., 1995)

Larval heterozygotes with Df(2L)JS17 exhibit reduced fat body, midgut defects and greatly reduced gastric caecae and dissected pupae exhibit absent or severely reduced imaginal discs.

(Sekelsky et al., 1995)

Addition of Mad¹²/+ to animals expressing anchor^GD3613 under the control of Scer\GAL4^A9 partially suppresses the thickened wing vein phenotype and suppresses the increased wing size phenotype, to the extent that it is decreased compared to flies with Scer\GAL4^A9 driver alone.

(Wang et al., 2018)

The decreased number of synaptic boutons at the third instar larval neuromuscular of Mad¹²/Mad^k00237 transheterozygotes is not suppressed or enhanced by either Nrx-1²⁷³ or Nlg1^Δ46 homozygosity.

(Banerjee et al., 2017)

Mad¹²/+ suppresses the increase in total boutons (and satellite boutons) at the neuromuscular junction in Ube3a³⁵/Ube3a³⁵ third instar larvae.

(Li et al., 2016)

The progeny from Mad¹²/+ mothers and dpp^hr4/+ fathers present embryo ventralization in less than half of cases, and near lethality, as compared to controls; the progeny from Mad¹²/+ mothers and dpp^hr27/+ fathers, but not dpp^hr56/+ or dpp^e87/+ fathers, exhibit semi-lethality, as compared to controls.

(Quijano et al., 2016)

The neuromuscular junction overgrowth phenotype (increased total number of boutons and increased number of satellite boutons) of brat¹¹/brat^2L-192-9 larvae is significantly suppressed by Mad¹²/+.

The reduced uptake of FM1-43 dye seen at the neuromuscular junction in brat¹¹/brat^2L-192-9 larvae is significantly suppressed by Mad¹²/+.

Dcr-1^Q1147X mutant germline stem cells lacking one copy of Mad¹² show clear stem cell maintenance defects when clones are generated during late larval/early pupal stages.

Expressing Dl^{Scer\UAS.P\T.cJa} under the control of Scer\GAL4^nos.PG in Mad¹² mutant GSCs during the larval/pupal stages results in an enlargement of the niche at 7 and 14 days after clone induction. No stem cell maintenance defects are observed. The number of Mad¹² mutant GSCs in the enlarged niche increases from 7 days to 14 days.

(Shcherbata et al., 2007)

Eye disc cells simultaneously mutant for Mad¹², ci⁹⁴ and Su(H)^del47 continue proliferating instead of arresting in G1 ahead of the morphogenetic furrow. The same phenotype is seen in cells mutant for Mad¹² and ci⁹⁴ - the presence of Su(H)^del47 has no autonomous effect on G1 arrest.

G1 arrest is delayed in Mad¹², Su(H)^del47 eye disc cells.
