The indispensable contribution of s36 protein in biogenesis of chorion’s radial complexity.
(A,B) Transmission electron micrographs of representative control (c355-GAL4/+) follicles. (C–H) Transmission electron microscopy images of eggshell’s ultrastructural organization in s36-downregulated (c355 > s36_RNAi) follicles. Phenotypic variation (C–H) dictates the ability of s36 to modulate developmental randomness likely evolved during chorion’s assembly.
