Male tail phenotype resulting from mutations in lon-8. (A), (B), DIC micrographs of ventral views of representative male tails of him-5(e1490) and lon-8(hu187) animals. Bar is 20 μm. Whereas rays 1–9 can clearly be distinguished in wild type males, in lon-8 males they are clumped together as an amorphous mass. (C)-(F) DIC and fluorescence micrographs of approximately 40 hour old him-5(e1490) males expressing lon-8::gfp in the lateral and ventral part of the tail hypodermis. These are, from 1–7: V6.pppaa, T.aa, R6.p, T.apapa, R7.p, R8.p and R9.p. "Set" indicates the male tail seam. (C)-(D) left lateral view, (E)-(F) mid-plane view.
