NASC ID: N2110920

Name: asl9

ABRC stock number: CS2110920

Description: asl9-1 has a premature stop codon at the 19th codon via an insertion of a single nucleotide “A”. This was generated using CRISPR-CAS9 system. pJY-35SpCas9-RG1 binary construct was used to target LBD3/ASL9 via agrobacterium-mediated transformation, in which 35S promoter and AtU6 promoter drive Cas9 and sgRNA, respectively. Three 20-mer targeting regions were selected for CRISPR guide sequences, based on the prediction results from CRISPR RGEN Tools (www.rgenome.net): RG1 (5’-AGACAAAAGGGTCACAGACA-3’); RG2 (5’-TCGCCGGAGAAGTTTACAGC-3’); and RG3 (5’-GGCTCTTTGGCCGGAAAATA -3’). Eight hygromycin-resistant transgenic T1 plants harbouring the CRISPR cassette either with sgRNA-RG1, RG2, or RG3 were grown for T2 germline transmission of potentially edited alleles. Sanger sequencing analyses on targeted regions from T2 progenies revealed that targeted RG1successfully generated homozygous asl9-1 allele. After confirming the mutation, T-DNA containing CRISPR-CAS9 was removed by outcrossing to the Col-0 wild type..
