This strain carries a dpy-5 mutation to facilitate genome modification in CeRep55 quadruple deletion background: fjDf1 (also known as fj115); fjDf2 (aka fj85); fjDf3 (aka fj123); fjDf4 (aka fj120) X. This strain lacks four major clusters of CeRep55 repeats on the X chromosome. The condensation of unpaired X chromosomes in male testes is insufficient. CeRep55 is a class of minisatellite sequences consisting of a 27-nt tandem repeat that is present on all chromosomes. Some CeRep55 clusters express long non-coding RNAs and small RNAs. Each of the four deletion sites was designed to acquire a sequence tag (TGTACAGGAAACAGCTATGACC; similar to M13 reverse) instead of the CeRep55 tandem repeats. The deletions of CeRep55 clusters can be checked by PCR with the following primers: fjDf1 in Y73B3A, CAACCTGACTCTCGCCAAGAC and GGAGAAGTAGGCGTGTCAGTTA; fjDf2 in Y75D11A, CAAGTGCCAAACTAGACTGCTC and TTCAAAACGCTACGCGATACCAG; fjDf3 in Y81B9A, AAATGCCCCTATCTCACAGTGG and GACTGCTAGAATCTGACTCGTC; fjDf4 in Y49A10A, CAACCTGACTCTCGCCAAGAC and GGAGAAGTAGGCGTGTCAGTTA. The PCR check can also be performed with the M13 reverse primer and the right-side primer. Reference: Tabara H, et al.
