The egl-27 reporter is expressed in the Y cell in the 1.5-fold embryonic stage as well as during the L1 larval stage, which precedes the initiation of Y transdifferentiation.
A short gcy-33 promoter fragment is expressed in the BAG sensory neurons ( Yu et al., 1997 ), here was observed that an extended gcy-33::GFP reporter gene fusion was expressed in BAG, URX, AQR, and PQR neurons.
wdr-5.1 was nuclear-localized in Y/PDA throughout transdifferentiation.In some cases faint additional WDR-5.1::GFP staining was observed in the cytoplasm.
