Expression Pattern :

Pattern  We used a putative promoter 5 kb sequence immediately upstream of the start codon of pezo-1 isoforms i and j. GFP expression was mainly restricted to pharyngeal muscles and sensory neurons. In the pharynx, we saw GFP labeling of the pm3 muscle cells, the mc1 marginal cells in the corpus, a structure responsible for generating suction forces during the ingestion of suspended bacteria (Raizen et al. 2012), and in a neuron consistent in location and morphology with I4. A ventral cell located posterior to the terminal bulb and extending a process dorso-anteriorly toward the pharyngeal-intestinal valve (consistent with the excretory gland) was also labeled. Based on their location and characteristic extensive branching, we identified the anterior and posterior mechanoreceptors FLP and PVD (respectively) as also expressing GFP. Posteriorly, we tentatively identified a phasmid neuron consistent with the PHC neuron's morphology and location, as well as other cells associated with the uterus and anus, as expressing GFP. Unlike the other transcriptional constructs, GFP expression in these animals was visible as early as prezle-stage embryos. Primary Identifier  Expr16580
