Fig. 1. Cuticular phenotypes associated with tup clones. (A)
View of the lateral-posterior region of a notum displaying ectopic structures
in a fly bearing f tup2 clones. The framed area is shown
at high magnification in B, after mounting of the cuticle. (B) S1 and
S2, extant first and second axilary sclerites; S1' and S2',
recognisable ectopic sclerites; asterisk and tg', mass of sclerotised
tissue and an ectopic tegula-like structure, respectively, bearing
macrochaetae and sensilla trichoidea. (C) Ectopic tegula (arrow) with
ytupex4 bristles, and extant tegula (arrowhead).
(D) Pedicel of a haltere (asterisk) showing rows of sensilla
campaniformia (white arrowheads). Black arrowhead, ectopic structure on the
metanotum bearing at its base pedicel-like sensilla campaniformia (arrows).
Insets show boxed regions at high magnification. (E) Protuberance on
the anterior lateral notum with f tup2 microchaetae
(arrowhead). (F) Notum showing loss of tissue and of bristles in the
scutellum (arrow) and a vesicular invagination (arrowhead). (G) High
magnification of the vesicle shown in F. Arrowhead, group of sensilla
campaniformia. (H,I) Two focal planes of an invagination with
y tupex4 microchaetae arising from its interior
(arrowhead). Green line, contour of a crinkled (ck)-marked
twin-spot which covers the invagination. (J) Cuticular defects (arrow
and arrowheads) on the scutum and scutellum of a fly with
ftupisl-1 clones. (K) Protuberance/invagination
(indicated by the arrow in J) at high magnification. Note the apical hole of
the invagination, and the abutting ck twin-spot tissue in the
top-left corner of the panel. (L) Malformation with a central
depression and ftup2 macro and microchaetae. Red,
sensillum campaniforme, as shown at higher magnification in the inset. In K
and L, some of the mutant ftup bristles are coloured yellow.
