CRISPR-Cas interference decays rapidly with distance from the leader sequence in a long array

Marijn Ceelen, Mauro Albertini, Gregory J. Velicer, Sébastien Wielgoss

The paper shows that CRISPR-Cas interference in Myxococcus xanthus declines rapidly with distance from the leader sequence, with only ~4% of spacers effective, contrasting with ~95% effectiveness in Vibrio cholerae.
