Abstract: Recent years have witnessed transformative breakthroughs in plant disease resistance research, particularly in deciphering the intricate interplay between hosts and pathogens. Cutting-edge discoveries span pathogen recognition mechanisms, immune signaling cascades, and multi-layered interactions integrating plants, pathogens, vectors, and environmental variables. Notably, pioneering studies from domestic research institutions have driven progress across pathogen-sensing systems, secondary metabolite-mediated defense, immune module engineering in crop, and artificial intelligence (AI) -powered solutions for pathogen-resistant peptide design. The rapid development of CRISPR/Cas9-based gene editing technologies and AI has further empowered researchers to engineer disease-resistant crop varieties with unprecedented precision. Such progress holds profound implications for ensuring national food security and advancing strategic priorities in disease-resistant crop breeding, marking a transformative era in agricultural biotechnology and sustainable agriculture.
