Strain information
Strain ID MT1209
Strain Name ZRSdelta3.4kb
Strain Type Mutants
Characteristics A 3.4 kb deletion was generated by CRISPR/Cas9 in the region harboring ZRS and shadow ZRS (sZRS) enhancers (Intron 5 of Lmbr1 gene, chromosome 20). Both enhancers drives expression of shh gene to pectoral fin buds. CRISPR targeted sequences are GTCCAGCTGTATTACCATGCAGG and TGGCCTCTAACGAGCCACACGGG. The original background of this mutant is Cab strain. In pectoral fin buds, shh gene expression is not detected by in situ hybridization. The pectoral fins are completely failed.

Upper pannels, expression of shh at 3 dpf is absent in pectoral fin buds from ZRS+sZRS. 3.4 kb deletion mutants.
Lower pannels, ZRS+sZRS. 3.4 kb deletion mutants lack pectoral fins.
