Abstract

In Europe as in North America, elms are devastated by Dutch elm disease (DED), caused by the alien ascomycete Ophiostoma novo-ulmi. Pathogen dispersal and transmission are ensured by local species of bark beetles, which established a novel association with the fungus. Elm bark beetles also transport the Geosmithia fungi genus that is found in scolytids' galleries colonized by O. novo-ulmi. Widespread horizontal gene transfer between O. novo-ulmi and Geosmithia was recently observed. In order to define the relation between these two fungi in the DED pathosystem, O. novo-ulmi and Geosmithia species from elm, including a GFP-tagged strain, were grown in dual culture and mycelial interactions were observed by light and fluorescence microscopy. Growth and sporulation of O. novo-ulmi in the absence or presence of Geosmithia were compared. The impact of Geosmithia on DED severity was tested in vivo by co-inoculating Geosmithia and O. novo-ulmi in elms. A close and stable relation was observed between the two fungi, which may be classified as mycoparasitism by Geosmithia on O. novo-ulmi. These results prove the existence of a new component in the complex of organisms involved in DED, which might be capable of reducing the disease impact.

摘要

在欧洲和北美的榆树上，榆枯萎病（DED）导致榆属植物大量死亡，这种疾病是由外来的子囊菌 Ophiostoma novo-ulmi 引起的。病原体的传播和传播是由当地的树皮甲虫来保证的，这些甲虫与真菌建立了一种新的共生关系。榆树皮甲虫还携带在被 O. novo-ulmi 殖民的树皮甲虫洞穴中发现的 Geosmithia 真菌属。最近观察到 O. novo-ulmi 和 Geosmithia 之间广泛的水平基因转移。为了在 DED 病理系统中定义这两种真菌之间的关系，从榆树上分离出包括 GFP 标记菌株在内的 O. novo-ulmi 和 Geosmithia 物种，在双培养中进行培养，并通过明场和荧光显微镜观察菌丝体相互作用。比较了在没有或存在 Geosmithia 的情况下 O. novo-ulmi 的生长和孢子形成。通过将 Geosmithia 和 O. novo-ulmi 共同接种到榆树上，在体内测试了 Geosmithia 对 DED 严重程度的影响。观察到两种真菌之间存在密切而稳定的关系，这种关系可能被归类为 Geosmithia 对 O. novo-ulmi 的菌寄生。这些结果证明了在参与 DED 的复杂生物群中存在一个新的组成部分，它可能有能力降低疾病的影响。
