Figure 5. Gene structure and expression pattern of
ser-3. A,
ser-3 gene is located on the cosmid K02F2. The gray bar indicates the region deleted in the
ad1774 allele. The regions used for the reporter fusion (
ser-3::gfp) and in the rescue experiments are also indicated. B-E, The fluorescent images were taken from animals carrying
ser-3::gfp. The expression of GFP and DiI staining of sensory neurons are shown in green and red, respectively. ASH, ASJ, PHA, and PHB neurons are stained by DiI. UTR, Untranslated region. B, GFP expression was observed in various tissues, including neurons, head muscles, intestine, spermatheca, and eggs. C, In the head region, GFP expression was observed in several neurons, including SIA neurons. D, In the tail region, GFP expression was observed in PHA, PHB, and PVQ neurons and phasmid socket cells. PHA and PHB appear yellow because they are both stained with DiI and are expressing GFP. E, Weak GFP expression was observed in the gonad and the vulva. White dotted lines indicate the outlines of the head (C) and the tail (D) of the animals. Scale bars: B, 100 um; C-E, 20 um.
