Whole mount in situ hybridization of Bombyx fng and BmWnt-1, Bombyx homolog of wg in wing discs. (A and B) Expression of Bombyx fng in wing discs (A, dorsal view; B, cross-section). The fng cDNA antisense probe was hybridized to the wing discs of last instar larvae. (C) DAPI staining in cross-section. D, dorsal; V, ventral; tr, trachea. (D–G) Expression of BmWnt-1 in wing discs. BmWnt-1 cDNA antisense probe was hybridized to the wing discs of the last instar larvae. D and F show the expression patterns in wild-type and fl wing discs, respectively. E and G show the schematic representation of the BmWnt-1 expression in wild-type and fl wing discs, respectively. Bars, 0.5 mm.
