Derived from OK0469 [cuEx363] following EMS mutagenesis. The ceh-22
::gfp fusion pOK185.01 (kindly provided by T. Vilimas) contains an SphI to XhoI ceh-22
promoter fragment (bp 14719 to 17467 of F29F11, accession Z73974) (Kuchenthal et al., 2001) fused to a gfp::his2
B orf derived from SEM474 (Gaudet and Mango, 2002) to promote tight nuclear localization of GFP.
