Figure 4. Expression Patterns of
evl-20. Expression patterns were analyzed in stable
unc-119-rescuing lines with an extrachromosomal array carrying
evl-20::gfp transcriptional reporter construct and a wild-type
unc-119 genomic fragment.(A-C) Nomarski, fluorescence, and merged images of a wild-type embryo during hypodermal enclosure, respectively (ventral view). Expression of
evl-20::gfp reporter is seen in migrating hypodermal cells. In these panels, anterior is to the left, and right is to the top. Scale bar in (A) is 5 um.(D-F) Nomarski, fluorescence, and merged images of the mid region of a wild-type hermaphrodite in mid L4 stage, respectively (lateral view). Expression of
evl-20::gfp reporter is seen in the vulva and the uterus. Scale bar in (D) is 10 um.(G-I) Nomarski, fluorescence, and merged images of a wild-type male tail in early L4 stage, respectively (lateral view). Expression of
evl-20::gfp reporter is seen in the proctodeum and some other cells. Scale bar in (G) is 10 um.
