A TI{CRIMIC.TG4.0} DNA cassette has been inserted into ara, in a coding intron, and is predicted to gene trap all annotated transcripts of the gene. The TI{CRIMIC.TG4.0} cassette was inserted via the CRISPR/Cas-9 drop-in technique, using a dsDNA donor vector with homology arms of length 200bp. The sgRNA sequence used to target the gene was: CTGGTTGGCCCTGTCGAGCCGGG. The PCR check gave the expected-sized band for the right flank and a shorter than expected band for the left flank. The right flank was verified by sequencing.
