wzIs30 [egl-6::ChR2-YFP + lin-15(+)] IV. Strain carries integrated transgene wzIs30 that expresses YFP-tagged channelrhodopsin under the egl-6 promoter in HSN and some head and tail neurons. Strain is in lite-1(ce314) and lin-15(n765ts) background. The transgene contains a rescue for lin-15 as a marker. Reference: Emtage L, et al. J Neurosci. 2012 Nov 14;32(46):16285-95.
