The scaleless wings mutant in Bombyx mori is associated with a lack of scale precursor cell differentiation followed by excessive apoptosis.

Abstract excerpt

The scaleless wings mutant in Bombyx mori (scaleless, sl) was previously reported morphologically. In the present study, we give data to clarify the mechanism of the mutation at the developmental level. Programmed cell death participates in the wing scale development during early pupal stage, and there are significant differences between that of sl and the wild type (WT) at each phase. Well-differentiated scale...
