摘要： How to balance rice resistance and yield is an important issue in rice breeding. Plants with mutated necrotic lesion genes often have persistent broad-spectrum resistance, but this broad-spectrum resistance usually comes at the expense of yield. Currently, many necrotic lesion mutants in rice have been identified, and these genes are involved in disease resistance pathways. This review provides a detailed introduction to the characteristics, classification, and molecular mechanisms of necrotic lesion formation. Additionally, we review the molecular regulatory pathways of genes involved in rice disease resistance. Concurrently, we summarize the relationship between resistance and yield in rice using newly developed gene editing methods. We discuss a rational and precise breeding strategy to better utilize molecular design technology for breeding disease -resistant and high -yield rice varieties.
