Su(H)1/Su(H)IB115 mutant tissues exhibit a loss of ptc-positive prohemocytes and the overproduction of differentiated plasmatocytes. By contrast, an increase is not observed in the crystal cell population in Su(H)1/Su(H)IB115 mutant lymph glands.
Dorsal, ventral and dorsoventral clones that extend to the wing margin produce extensive scalloping.
Lethality during the first day of pupal development. Supernumerary cells stained in mutant imaginal discs have adopted a sensory organ precursor (SOP) fate instead of the epidermal fate they would normally express. The excess SOPs arise from the proneural clusters of potential precursor cels that appear in the imaginal discs during the development of wild type bristles. The wing pouch region of the wing imaginal disc and the retinal field of the eye-antennal imaginal disc are dramatically reduced. Identical phenotype is seen when transheterozygous with Df(2L)TE35BC-24, Su(H)IB115, Su(H)2 or Su(H)8.
