摘要： BACKGROUNDVerticillium wilt is a critical disease affecting cotton in the Xinjiang province, a region producing 90% cotton in China. Defining the specific temperature thresholds for disease prevalence is essential but has remained unclear.RESULTSThis study aimed to establish a model to quantify the relationship between temperature and cotton verticillium wilt disease risk. Through a controlled temperature experiment, we identified a nonlinear temperature relationship, with an optimal temperature of 26.5 degrees C. Then a beta model, parameterized from these findings, was validated against historical regional disease data, confirming its ability to accurately reflect interannual variations in disease occurrence and its direct applicability from laboratory to regional scales. We then utilized the model to project future disease risks under two Shared Socioeconomic Pathways (SSP) climate scenarios. The projections estimate a 4.8% to 10.1% increase in disease risks in Xinjiang by the 2080s under SSP1-2.6 and SSP5-8.5 scenarios, respectively.CONCLUSIONThis research offers a valuable predictive tool for cotton verticillium wilt risks, informing strategic decisions for cotton production in the face of climate change. The successful application of a laboratory-derived model at a regional scale marks a significant advancement in plant disease risk assessment, underscoring temperature as a dominate factor in cotton disease dynamics.
