Nucleotide substitution: G?A. Mutation at exon 3 splice acceptor site.
Indistinguishable from wild type on Southern blot. Faint residual band on immunoblots (as for Df(1)C128) where product is thought to be a remnant from the maternal supply.
G8064532A
Reported as a G to A mutation in the splice acceptor. No protein detected in mutants.
Stage 14 oocytes carrying mys10 somatic clones are much more rounded than wild-type.
Homozygous clones in the wing produce discrete, round blisters of variable size. These blisters can be located anywhere on the wing. Wing venation is normal.
Clones present in the wing 4-6 hours after pupariation (AP) cause no morphological abnormalities. In 30 and 36 hour AP dorsal and ventral clones are associated with pronounced matrix-filled blisters. Blisters result from failure of mutant clone cells to reappose with normal cells in the opposite surface. Both mutant and normal cells generally fail to undergo the cell shape changes required for re-apposition. Clones induced late in larval development may be long but only a few cells wide, the dorsal and ventral surfaces in the adult wing are separated.
Dorsal wing clones as small as 50 cells display a wing blister phenotype.
No anti-βPS staining at muscle attachment sites.
Cells derived from homozygous late gastrula embryos appear less stretched out and more rounded and have fewer cell-cell contacts than wild-type cells when cultured in vitro on laminin-coated coverslips.
Folds in one or both surfaces of the wing, wing blisters, vein abnormalities and missing or enlarged halteres were seen in adults mosaic for mys function.
mys10, sog[+]/sogEP7 has wing vein | dorsal | somatic clone phenotype
mys10, sogEP7 has wing vein | dorsal | somatic clone phenotype
Small mys10 somatic clones in the wing generated a sogEP7 background cause distinct vein phenotypes: Dorsal clones that cross over or lie adjacent to longitudinal veins, such as L4 and L5 induce the formation of veins with diffuse borders that are less compact, less pigmented and wider than normal veins. Dorsal clones running over L3 induce dramatic vein thickening and diffuse vein borders. In contrast, ventral clones have no effect on veins.
When tested in the odour-induced jump test, mutants with the heteroallelic combination of mys10 with swsolfE-x26 show normal responses to iso-amyl acetate, ethyl acetate and benzaldehyde compared to controls.
mys10 fails to complement the isoamyl acetate olfactory response phenotype seen in mysolfC-x3, mysolfC-x5, mysolfC-x10 and mysolfC-x17.
Maternal germline clonal analysis demonstrates a maternal effect lethal phenotype that is rescuable by introduction of the wild-type copy of the gene from the father.
