Psn46/PsnW6 and Psn46/PsnW11 show early pupal lethality. The third instar larvae form a pupal case, but no adult structures develop. Mutant larvae show underdeveloped eye and wing discs. The eye imaginal disc fails to undergo proper neuronal differentiation. The wing imaginal disc is smaller with the most severe defects observed in the region that will give rise to the wing blade. The antenna and leg imaginal discs appear normal.
PsnW11/Psn[+] is an enhancer of wing vein L3 phenotype of Nnd-3
PsnW11 is a suppressor of wing vein L2 phenotype of NAx-1
PsnW11 is a suppressor of wing vein L5 phenotype of NAx-1
Nnd-3, PsnW11/Psn[+] has wing margin bristle phenotype
Nnd-3/N[+], PsnW11 has wing margin bristle phenotype
