Purpose / Description: Vector for single guide RNA targeting the phytoene synthase gene PSY1 with RNA scaffold for Streptococcus pyogenes Cas9 (SpCas9), controlled by the U6 snRNA promoter #4.
Reference: Targeting of Photoreceptor Genes in Chlamydomonas reinhardtii via Zinc-Finger Nucleases and CRISPR/Cas9
Vector for single guide RNA targeting the *phytoene synthase* gene PSY1 with RNA scaffold for *Streptococcus pyogenes* Cas9 (SpCas9), controlled by the U6 snRNA promoter #4. The vector contains an aphVIII cassette for selection on paromomycin.
