The chapter "Climate Change Effects on Plant Disease: Genomes to Ecosystems" by K. A. Garrett et al. reviews the impact of climate change on plant diseases, focusing on various scales from genomic to ecosystem levels. Key points include: 1. **Genomic Level**: Advances in high-throughput gene expression analysis have enabled the discrimination of responses to different stressors and potential trade-offs in responses. 2. **Individual Plant Level**: Experiments have synthesized the effects of climate variables on infection rates, though pathosystem-specific characteristics complicate synthesis. 3. **Population Level**: The adaptive potential of plant and pathogen populations is crucial for predicting the magnitude of climate change effects on plant diseases. 4. **Ecosystem Level**: Ecosystem ecologists are addressing the role of plant diseases in ecosystem processes, with potential for greater understanding of large-scale impacts. The chapter highlights the challenges and progress in studying climate change effects on plant diseases, including the need for more sophisticated models, closer links between empirical and modeling studies, and the consideration of multiple interacting factors. It also discusses the implications of climate change on disease management, the evolution of pathogens, and the potential for new patterns of host-sharing by pathogens. The authors emphasize the importance of integrating genomic, population, and ecosystem perspectives to better understand and manage the impacts of climate change on plant diseases.The chapter "Climate Change Effects on Plant Disease: Genomes to Ecosystems" by K.
