Fig. 2. Mutations in CSN5 cause eggshell defects. (A) A wild-type
eggshell. Note the length of the dorsal appendages (DA) and the separation at
their bases. (B-F) Eggshells derived from females carrying
CSN5-mutant, germline clones. (B,C) Fused or absent DA in weakly or
strongly ventralized eggshells. (D) A partially dorsalized eggshell. Bases of
the appendages are more widely separated than in wild type. (E) Short but
normally spaced DA. (F) An unusual eggshell with duplicated DA. In addition to
these eggshell defects, some eggs had an unusually weak eggshell. These eggs
were sometimes destroyed during attempts to move them. This phenotype may be
related to observations made during dechorionation or fixation that many eggs
from CSN5 GLC mothers fall into pieces.
