The ubiquitous snRNA:U6:96Ac promoter drives expression of a single sgRNA (GAGTCGACAACAGGTGAGTG) that targets plum.
Crispr-Cas9 mutagenesis of plum by expressing Spyo\Cas9UAS.Tag:NLS(Unk) under the control of Scer\GAL4GMR71G10 and using plumgRNA.pCFD3-2 as a guide, results in a high frequency of mushroom body gamma neuron pruning defects.
