WormMine: ExpressionPattern Expr11860

• Pattern: Fluorescence was observed in all developmental stages after hatching with strong expression in the nervous system and the somatic gonad during L2-L4 larval stages. Additionally, GFP signals were detected in the uterus as well as in the spermatheca of adult worms. Strong riok-1 expression was seen in the head neurons required for chemotaxis like the AWC neurons, the nerve ring (RID/RIF neurons), in inhibitory motor neurons (DA/DD/VA/VD), mechanosensory neurons (ALML/PLML), as well as in the tail sensory neurons (DVA/PDA). GFP was also detected in both nerve cords and associated commissures. In the L2-larva, GFP expression was observed in the somatic gonad as well as in the ventral nerve cord. In the L3-larva, riok-1 expression is maintained in the somatic gonad in ventral uterine (VU/AC) cells. After commitment, riok-1 is expressed in the anchor cell. In contrast, GFP expression could not be detected in the ventral precursor cells (VPCs) in the hypodermis. In the L4-larva, riok- 1 is expressed in the vulF cells of the vulva, cells of the uterus and the uterine seam cells (utse). In young adult worms, the riok-1 expression is maintained in the cells of vulva and the uterus.
