Fig. 4. ash2 is required for net activation. (A-C) Expression of
net mRNA in third instar wing discs. (A) Wild-type discs showing
net transcripts in intervein regions. The position of veins (lacking
net mRNA) is indicated. (B) net expression is reduced in
discs ash2112411/ash2112411. However, the
central domain of the wing pouch shows expression of net. (C) Absence
of net mRNA in ash2I1 wing discs. (D) Wing of
net1 homozygous mutant with ectopic vein tissue. (E)
net1/net1; ash2I1 heterozygous flies
show posterior wing blistering and enhanced ectopic vein connections,
especially between L2-L3. (F) Wings of net1;
ash2112411 homozygous flies exhibit a total fusion of L2-L3
and L4-L5 with the corresponding loss of intervein regions B and D. The size
of the wing is also reduced and the posterior margin is partially lost. (G)
High magnification of L2 and L3 fusion, which is mostly associated with L2
thickening, as L5 is for L4-L5 fusion. Note the ventral pattern of corrugation
in L2 and the sensillia campaniforme, and dorsal corrugation in
L3.
