| Pattern | The pry-1 reporter gene is widely expressed throughout development. Expression starts halfway through embryogenesis and is mainly localized to the ventral and lateral hypodermal cells. At the early L1 stage, pry-1 is expressed at high levels in the lateral hypodermal cells (or seam cells) V5 and V6 and in the Q neuroblasts QL and QR. pry-1 is also expressed in the ventral hypodermal (P) cells P7/8 to P11/12, body wall muscle cells, and neurons in the head, the tail, and the ventral nerve cord. No differences in pry-1 expression levels between QL and QR was observed, but this may be a result of PRY-1 GFP overexpression. At the end of the L1 stage, pry-1 is expressed at high levels in all seam cells. Expression was also observed in the QL and QR daughter cells. At later larval stages, pry-1 is expressed at high levels throughout the animal, including hypodermal cells, body wall muscle cells, and many neurons in the ventral nerve cord and head and tail ganglia. In addition, pry-1 is expressed in the vulva precursor (Pn.p) cells and in the developing vulva and male tail. | ||

| Remark | The expression pattern of this construct was similar in independent transgenic lines, but the subcellular localization of the PRY-1 GFP fusion protein differed, ranging from localization at the plasma membrane and in cytoplasmic dots to diffuse cytoplasmic and nuclear staining. This difference in subcellular localization may be a consequence of variations in expression levels of the fusion protein in different transgenic lines. For ease of cell identification, a transgenic line showing diffuse cytoplasmic and nuclear staining was selected. This transgene fully rescued the lethality, the multivulva phenotype, and the QR.d migration defect of pry-1(mu38 and nc1). This suggests that the PRY-1 GFP fusion protein is functional and is correctly expressed in cells in which PRY-1 is essential. | ||
