| Abstract | Potato, the world's third most important food crop, is frequently challenged by both biotic and abiotic stresses. Among these, late blight—caused by Phytophthora infestans—is one of the most destructive pathogens. Current management often involves intensive fungicide application, with up to 18 treatments per season, leading to high costs and environmental concerns. While nitrogen (N) is essential for plant growth, excessive N may increase susceptibility to late blight, making nitrogen balance crucial for both yield and disease resistance. This study uses RNA-seq to compare two potato cultivars, Victoria and Gasoré, which differ in both late blight resistance and nitrogen-use efficiency. We provide insights into molecular mechanisms that link nitrogen utilization with late blight resistance, highlighting key transcription factors and pathways that could guide the development of more resilient and nitrogen-efficient potato cultivars. |
