WebAs a precise genome editing technology, base editing is broadly used in both basic and applied plant research. Cytosine base editors (CBEs) and adenine base editors (ABEs) represent the two commonly used base editor types that mediate C-to-T and A-to-G base transition changes at the target sites, respectively. To date, no transversion base editors … WebCBEs were first reported by Liu and co-workers in 2016 , and base editor 1 (BE1) was developed by fusing a naturally existed cytidine deaminase rAPOBEC1 to dCas9 (Cas9 variants containing both D10A and H840A mutations). rAPOBEC1 catalyzes cytosine (C) deamination into uracil (U), which is recognized as thymine (T) in base-pairing process; …
