Gene editing technology provides new opportunities to enhance maize disease resistance, while environmental factor studies contribute to increased agricultural productivity. In recent years, genome sequencing and genome-wide association studies have identified multiple disease resistance genes, particularly R genes, which play crucial roles in defense against fungi, bacteria, and viruses. Additionally, signaling molecules such as NPR1 and MAPK are key in the expression of defense genes and systemic acquired resistance. Future research directions include optimizing the efficiency of gene editing techniques like CRISPR/Cas9, leveraging diversity and population genomics to identify the genetic basis of disease-resistant traits, exploring the effects of climate change and soil conditions on disease resistance, constructing an integrated model of maize disease resistance mechanisms, and examining molecular interactions between pathogens and maize. This paper aims to synthesize the progress and challenges in research on disease resistance mechanisms in corn and provide a reference for future research directions.
