syb3311 created by the insertion of a tandem array containing seven copies of the GFP11 beta-strand (gfp11x7) in the endogenous casy-1 locus; can be crossed with reporter lines expressing the complementing split GFP fragment (gfp1-10) in specific cell types to facilitate tissue-specific labeling. Split-GFP tag inserted into endogenous casy-1 locus using CRISPR/Cas9 with two guide RNAs simultaneously. Reference: Ding C, et al. Elife. 2022 Mar 14;11:e73557. PMID: 35285800.
