Abstract:Citrus canker, caused byXanthomonas citrisubsp. citri (Xcc), is a devastating disease worldwide. Previously, we successfully generated canker-resistantCitrus sinensiscv. Hamlin lines in the T0 generation, achieving a mutation efficiency of 97.4%. This was achieved through the transformation of embryogenic protoplasts using the Cas12a/1 crRNA ribonucleoprotein (RNP) system to edit the canker susceptibility gene,CsLOB1, which led to small indels. Here, we transformed embryogenic protoplasts of Hamlin with Cas12a… Show more
