High densities of antagonistic Streptomyces are associated with plant disease suppression in many soils. Here we review use of inoculation and organic matter amendments for enriching antagonistic Streptomyces populations to reduce plant disease and note that effective and consistent disease suppression in response to management has been elusive. We argue that shifting the focus of research from short-term disease suppression to the population ecology and evolutionary biology of antagonistic Streptomyces in soil will enhance prospects for effective management. A framework is presented for considering the impacts of short- and long-term management on competitive and coevolutionary dynamics among Streptomyces populations in relation to disease suppression.
高密度的拮抗链霉菌与许多土壤中的植物病害抑制有关。在这里，我们回顾了使用接种和有机质改良剂来富集拮抗链霉菌种群以减少植物病害的方法，并指出，针对管理措施的有效且一致的病害抑制效果一直难以实现。我们认为，将研究重点从短期病害抑制转移到土壤中拮抗链霉菌的种群生态学和进化生物学上，将提高有效管理的前景。本文提出了一个框架，用于考虑短期和长期管理对与病害抑制有关的链霉菌种群之间的竞争和共同进化动态的影响。
