<span class="paragraphSection"><div class="boxTitle">Abstract</div>Baculovirus, an insect virus commonly used for recombinant protein expression in insect cells and gene delivery in mammalian systems, is often generated through bacmid-based engineering. To enable flexible and programmable bacmid engineering, we developed SHOT 2.0, an optimized CRISPR-associated transposon platform that mediates RNA-guided and customized bacmid editing in <span style="font-style: italic;">Escherichia coli</span>. The edited bacmid can be transfected into insect cells to produce recombinant baculoviruses. SHOT 2.0 supported site-specific integration of large DNA cargos (at least 14 kb) into defined loci such as <span style="font-style: italic;">v-cath</span> and <span style="font-style: italic;">ODVe56</span>, with integration at <span style="font-style: italic;">ODVe56</span> markedly improving transgene stability during serial virus passaging. The system is fully compatible with the Bac-to-Bac^® workflow, enabling dual-gene insertion into the bacmid and derived baculovirus. Leveraging this platform, we constructed an all-in-one baculovirus encoding the PE5max prime editor. This vector-mediated prime editing achieves efficiencies up to 85.6% in HEK293T cells and achieves robust prime editing in hard-to-transfect cell types, including iPSCs and liver cancer cells, with efficiencies up to 37.1%. These results demonstrate that SHOT 2.0 substantially expands the baculovirus engineering toolbox, providing a flexible platform for genome editing and future gene delivery.</span>
