Abstract
Climate change seriously challenges agricultural production, profoundly impacting crop disease resistance. This paper aims to explore research directions on the impact of climate change on maize disease resistance gene expression, with a focus on the multidimensional effects on maize disease resistance. First, the paper reviews the importance of genomics and transcriptomics in identifying key disease-resistance genes and their regulatory mechanisms. Next, it discusses how metabolomic analysis reveals the effects of climate change on plant hormones and disease-resistant compounds, as well as the relationship between these metabolites and disease-resistance gene expression. Subsequently, the necessity of climate condition simulation experiments is introduced to observe how various environmental factors affect disease resistance gene expression and resistance capability. Additionally, the application of transgenic technology in enhancing disease resistance gene expression is mentioned, underscoring its potential in addressing the challenges posed by climate change. Finally, this paper highlights the importance of long-term monitoring and data analysis, ecological research, and comprehensive multi-factor studies to fully understand the mechanisms of climate change’s impact on maize disease resistance. These studies are expected to provide a scientific basis for maize breeding and management practices to enhance disease resistance in changing environments, thus safeguarding future food security and sustainable agricultural development.
