Heterobasidion viruses have previously been shown to affect each other's transmission and phenotypic effects on their hosts in a complex way. In this work, Heterobasidion parviporum strains hosting five coinfecting viruses simultaneously were constructed and used as donors in transmission experiments. They showed that viruses move more frequently between the mycelia of the same species than between the mycelia of H. parviporum and Heterobasidionannosum. One of the strains was used to show that coinfection of five viruses is relatively unstable in a natural environment and analyses of the growth rate and competitive ability of Heterobasidion strains hosting various virus combinations revealed that viral effects are not additive. The results also supported the view that the transmission of the promising virocontrol agent HetPV13-an1 may be enhanced by coinfecting viruses in the donor mycelium. However, its detrimental effects may be blocked by the presence of other viruses in the same mycelium. REPOSITORIES: GenBank accession number MN058080.

Heterobasidion sp. 上的多种病毒感染。

先前已证明异型担子病毒以复杂的方式影响彼此的传播和对宿主的表型效应。在这项工作中,构建了同时承载五种共感染病毒的 Heterobasidion parviporum 菌株,并将其用作传播实验中的供体。他们表明,病毒在同一物种的菌丝体之间比在 H. parviporum 和 Heterobasidionannosum 的菌丝体之间移动更频繁。其中一种毒株被用来表明五种病毒的共感染在自然环境中相对不稳定,并且对承载各种病毒组合的异型担子毒株的生长速率和竞争能力的分析表明,病毒效应不是累加的。结果还支持这样的观点,即有希望的病毒控制剂 HetPV13-an1 的传播可能会通过共感染供体菌丝体中的病毒而增强。然而,它的不利影响可能会被同一菌丝体中其他病毒的存在所阻止。存储库:GenBank 登录号 MN058080。
