Description

The U6:1 (snRNA:U6:96Aa) and U6:3 (snRNA:U6:96Ac) promoters (from the pCFD4 vector) regulate expression of two sgRNA sequences (GCTGGTGATTACGTCGGTGA and TGCGGGACCATCCGGGTACC) targeting loaf.

      CRISPR/Cas9 mutagenesis of loaf in the eye (Spyo\Cas9UAS.P2, loafgRNA.snRNA:U6:96Aa.snRNA:U6:96Ac) leads to the mis-targeting of R7 axons from the medulla M6 layer to the M3 layer.
