CRISPR/Cas13a (formerly C2c2) from the bacterium Leptotrichia shahii is an RNA-guided CRISPR system that targets sequences in RNA rather than DNA. PAM is not relevant for an RNA-targeting CRISPR, although a guanine flanking the target negatively affects efficacy, and has been designated a "protospacer flanking site" (PFS). GUIDE-Seq3’ Homology is much more important than 5’ Homology. Thanks to this wonderful loophole, as long as 15-20 bases at the 3’ end of the primer are absolutely conserved from the target sequences, we can add up to ~30 bases to the 5’ end without negatively impacting the reaction.The flanking sequences, copy number, and presence of backbone sequences, and overall transgene insertion structure were determined for each of the plant genomes, with the additional identification of moderate-sized secondary insertions that would have previously been missed. ...
