Fig. 6. Sktl is required for actin organization. Wild-type (A-E) and sktl^2.3 mutant (F-O) Drosophila germline clones co-stained for plasma membrane (B,G,L, green in merge A,F,K) and F-actin (C-E,H-J,M-O, red in merge A,F,K). Interruption of the actin cortex along the anterior margin is found in 36% of mutant oocytes (arrowheads in I,J). Ectopic F-actin structures are observed in 15% of mutant oocytes. D,I,N are magnifications from C,H,M, respectively. E,J,O are optical cross-sections of C,H,M, respectively, at the level of the red arrowheads. Asterisk, nucleus.
