Background: Data bottlenecks and saturation limits in multi-locus genome editing of monocotyledonous plants (monocots) Existing single-Cas9-based double-strand break approaches reliant on stochastic repair mechanisms have led to significant reductions in precise genomic modifications, particularly in engineering complex traits such as drought tolerance and enhanced nutritional content in staple crops like rice and maize. This unpredictability hinders large-scale deployment of climate-resilient crop pipelines.

Summary: This pioneering study addresses longstanding inefficiencies and structural insertion limitations in multi-locus genome editing within monocot crops by deploying a Twin Prime Editing infrastructure. By integrating a dual-pegRNA strategy enabling simultaneous template-directed reverse transcription across complementary strands, the computational platform optimizes multi-gene editing kinetics. Experimental validation demonstrated a robust threefold enhancement in precise editing velocities for insertion, deletion, and replacement operations over conventional prime editing methods, successfully integrating traits for drought resilience and nutritional enhancement in standard rice and maize populations. This advancement provides a non-invasive computational framework to minimize false-positive structural variants, calculate multi-gene editing probabilities, and guide universal agricultural stratification strategies.
