Viruses, bacteria, and eukaryotic symbionts interact with algae in a variety of ways to cause disease complexes, often shaping marine and freshwater ecosystems. The advent of phyconomy (a.k.a. seaweed agronomy) represents a need for a greater understanding of algal disease interactions, where underestimated cryptic diversity and lack of phycopathological basis are prospective constraints for algal domestication. Here, we highlight the limited yet increasing knowledge of algal pathogen biodiversity and the ecological interaction with their algal hosts. Finally, we discuss how ecology and cultivation experience contribute to and reinforce aquaculture practice, with the potential to reshape biosecurity policies of seaweed cultivation worldwide.

藻类病理学的重新出现：当藻类生物学遇到生态学和生物安全时

病毒、细菌和真核共生体以多种方式与藻类相互作用，引起疾病复合体，常常塑造海洋和淡水生态系统。藻类学（又名海藻农学）的出现代表了对藻类疾病相互作用有更深入了解的需要，其中低估的隐秘多样性和缺乏藻类病理学基础是藻类驯化的潜在限制。在这里，我们强调对藻类病原体生物多样性及其与藻类宿主的生态相互作用的了解有限但不断增加。最后，我们讨论生态和养殖经验如何促进和加强水产养殖实践，并有可能重塑全球海藻养殖的生物安全政策。
