Jae-Yean Kim is Professor of Applied Life Science at Gyeongsang National University and founder and CEO of Nulla Bio. His laboratory has spent a decade on the two hardest problems in plant genome editing: making precise edits work in dicots, and delivering them into genotypes that resist transformation. The group reported the first practical prime editing in tomato, developed the Ultra Prime Editor and a root-to-shoot system yielding T0 homozygous prime-edited Arabidopsis, and published Cas12a gene targeting with geminiviral replicons and dominant-negative KU80. This work appears in Nature Communications and Plant Biotechnology Journal. He founded Nulla Bio in 2022 to translate these platforms into crops, and chairs the Korean Society for New Plant Breeding Technology.
