Abstract Armillaria mellea and A. solidipes are two of the primary causal agents of Armillaria root rot (ARR) in over 500 woody hosts. Although extensive research on this disease has been conducted over the past few decades, finding controls for ARR has been challenging. This is largely due to the lack of knowledge of the fungal infection and host response processes. It is important to understand the infection process in order to develop new strategies to control the disease. In this review, the initial steps of the infection process of A. mellea and A. solidipes are discussed, with focus on fungal attachment and penetration. A mucilaginous substance produced at the rhizomorph tip is thought to aid attachment of the pathogen to host. Toxins and cell wall degrading enzymes produced by the fungus together with mechanical pressure generated by the rhizomorph is speculated to support fungal penetration. However, a detailed description of the Armillaria spp. infection process is lacking in the literature, and this illustrates the need for further studies.

蜜环菌和蜜环菌的感染过程

摘要蜜环菌和 A.solidipes 是蜜环菌根腐病 (ARR) 在 500 多种木质寄主中的两种主要病原体。尽管在过去的几十年中对该疾病进行了广泛的研究，但寻找 ARR 的控制措施一直具有挑战性。这主要是由于缺乏对真菌感染和宿主反应过程的了解。了解感染过程对于制定控制疾病的新策略非常重要。在这篇综述中，讨论了蜜蜂花和蜜蜂花感染过程的初始步骤，重点是真菌的附着和渗透。在根状茎尖端产生的一种粘液物质被认为有助于病原体附着在宿主上。据推测，真菌产生的毒素和细胞壁降解酶以及根状茎产生的机械压力支持真菌渗透。然而，蜜环菌属的详细描述。文献中缺乏感染过程，这说明需要进一步研究。
