Characterisation of Drosophila Ubx^CPTI000601 and hth^CPTI000378 Protein Trap Lines

Figure 8

Midgut analysis. (a) Wild type midgut with all 3 constrictions indicated by purple arrowheads. Left arrowhead: 1st constriction; middle arrowhead: 2nd constriction; right arrowhead: 3rd constriction. (b) The 2nd constriction is missing in homozygous Ubx ¹ mutant embryos [16]. (c)–(h) show several examples of Ubx-YFP embryos with complete midguts. The 2nd constriction of the midgut is indicated by purple arrowhead. Panel B is reproduced from [16] with permission.
