Viability is expressed as a percentage of the expected number. Wings from dmyc mutant adults were examined for trichome density to determine cell size (area). The number of trichomes from a specific region next to the posterior crossvein was counted within a 0.05 mm square and converted to area/cell (μM2). There were 43 squares from dmycP0 male wings, 31 each from dymcP1 and control male wings, and 34 from dymcP0; C765>dMyc male wings. Wing width is the distance from the posterior margin (at vein 5) perpendicular to the anterior margin. For wing length, vein 3 was measured from its origin in the hinge to the distal wing tip. A total of 20 dmycP0, 20 dmycP1, 26 dmycP0; C765>dMyc, and 15 control male wings were analyzed. Rescue of specific dmyc phenotypes by overexpression of dMyc cDNA was carried out by three means (see footnotes a–c). Complementation tests of dmycP0 with X chromosome deficiencies were carried out by crossing dmycP0 animals to wild-type (WT) flies or to flies carrying the deficiencies noted, and dymcP0/Df progeny were scored for viability. dymc is located at 3D5. (n), number of animals scored; nd, not determined.
Heat shock–induced (HS) dMyc transgene was used.
Scabrous Gal4 and UAS-dMyc used.
C765-Gal4 and UAS-dMyc used.
p ≤ .001 (reference = WT).
