Abstract

Crops increasingly face overlapping stresses such as heat, drought, salinity, and pathogens that conventional breeding or genome editing rarely overcome in combination. To address this, we propose CRISPR-enabled horizontal gene transfer (CRISPR-HGT) as a programmable framework that recreates the evolutionary process by which plants historically acquired adaptive microbial genes. Microbial genes, refined under extreme environments, provide a naturally preadapted resource for multi-trait resilience. By integrating tools such as Cas12a, CasΦ, RNA-targeting, and dCas-based epigenome editors with AI-guided microbial gene discovery, CRISPR-HGT enables modular and inducible stress regulation. This approach shifts genome editing from allelic modification to evolution-guided design. We outline a conceptual pipeline spanning microbial gene mining to adaptive field deployment, highlighting the ecological, biosafety, and regulatory dimensions, from the European Union's cautious oversight to the UK's product-based framework. CRISPR-HGT thus introduces an evolution-informed paradigm for engineering crops that anticipate stress and sustain yield under climate uncertainty.
