CRISPR/Cas9-mediated knockout of Neurog. (a) Tissue-specific (using Fog > Cas9) CRISPR/Cas9-mediated knockout of Neurog, using Asic > Unc-76:GFP as a reporter. Only 15/50 of Fog > H2B:mCherry + embryos also showed Asic > Unc-76:GFP-expressing BTNs. Open arrowhead indicates BTN with very faint reporter expression. (b) Control CRISPR embryo, showing Asic > Unc-76:GFP-expressing BTNs (white arrowheads). 42/50 of Fog > H2B:mCherry + control embryos had Asic > Unc-76:GFP-expressing BTNs. (c) Same conditions as in (a) but using GAD > Unc-76:GFP as an aBTN marker. Only 12/50 Fog > H2B:mCherry + embryos also showed GAD > Unc-76:GFP-expressing aBTNs. (d) Control CRISPR embryo, showing GAD > Unc-76:GFP-expressing aBTNs (white arrowheads). 39/50 of Fog > H2B:mCherry + control embryos had GAD > Unc-76:GFP-expressing aBTNs.
