Claim 0:
1. A gene editing system comprising one or more delivery vehicles, wherein:
the delivery vehicle(s) comprise RNA cargo,
said RNA cargo comprises (a) at least one mRNA molecule encoding (i) a nucleic acid programmable nuclease and (ii) a retron reverse transcriptase, (b) an engineered retron ncRNA, and (c) guide RNA for the nucleic acid programmable nuclease;
wherein the engineered retron ncRNA comprises an HDR nucleotide sequence substituted into a retron ncRNA;
wherein the retron ncRNA nucleotide sequence has about 85% to 98% sequence identity to any one of SEQ ID NO:15833, SEQ ID NO:18547, or SEQ ID NO:19053;
wherein the HDR nucleotide sequence is substituted at a hairpin loop of the retron ncRNA;
wherein the retron reverse transcriptase and the retron ncRNA are from the same phylogenetic clade;
each delivery vehicle contains (a)(i) and/or (a)(ii) and/or (b) and/or (c),
whereby one delivery vehicle or more than one delivery vehicle delivers (a)(i), (a)(ii), (b), and (c).
