Members of the family Partitiviridae are reported from a variety of fungal and plant taxa. After dsRNA-preparation, deep sequencing, and bioinformatics, we here reveal the existence of various divergent partitiviruses co-infecting the ectomycorrhizal fungus Sarcosphaera coronaria, symbiotically associated with the pine species Pinus brutia in Turkey. A total of 75 complete or nearly complete sequences related to the members of Alphapartitivirus and Betapartitivirus, were detected from the ascocarp sample of the fungal isolate. Two of the identified partitivirus genome segments encoding for partitiviral capsid protein represent evolutionarily distinct members of Alphapartitivirus, indicating that they may have diverged in the presence of long spatial isolation. In an attempt to match the two genome segments of the identified partitiviruses and distinguish individual species co-inhabiting a single host, nine possible genome segment pairs were identified.

据报道，Partitiviridae家族的成员来自各种真菌和植物类群。经过dsRNA的制备，深度测序和生物信息学研究后，我们在这里揭示了多种多样的Partitiviruses的存在，它们共同感染了与土耳其松树Pinus brutia共生的外生菌根真菌Sarcosphaera coronaria。从真菌分离物的果皮样品中检测到总共75个完整或接近完整的序列，这些序列与甲型和丙型病毒的成员有关。鉴定出的部分病毒编码的部分病毒的基因组片段中的两个代表了阿尔巴病毒的进化上不同的成员，表明在长时间的空间隔离下它们可能会发散。为了匹配已鉴定出的Partitiviruses的两个基因组片段并区分共同居住在单个宿主中的单个物种，鉴定了九个可能的基因组片段对。
