Abstract:
:Rosellinia necatrix is responsible for the white rot root disease of avocado in Southern Spain. Entoleuca sp. is a fungus isolated from roots of these same trees, but it is not pathogenic in avocado. Here, we describe two new species of partitiviruses detected in isolates of the avocado sympatric fungi Entoleuca sp. and R. necatrix, termed Entoleuca partitivirus 1 (EnPV1), genus Alphapartitivirus, and Entoleuca partitivirus 2 (EnPV2), genus Betapartitivirus. For both R. necatrix and Entoleuca sp., the dsRNA of the RdRp genomic segment of EnPV1 accumulates at a higher rate than the CP dsRNA, except for a set of Entoleuca sp. isolates where titers of the CP dsRNA are 35-50 times higher than those of the RdRp dsRNA and between 250-380 times higher than the CP dsRNA titers found in the rest of Entoleuca sp. and R. necatrix isolates. For EnPV2, the accumulation rates of the RdRp dsRNA in Entoleuca sp., is in most of the cases, higher than the CP dsRNA. In contrast, in R. necatrix isolates, EnPV2 dsRNA2 generally accumulates at a higher rate. Genetic analysis of the partitiviruses revealed that there is no apparent variation in the nucleotide sequences among the strains. RNA silencing of the partitiviruses appears to be limited in Entoleuca sp., as shown by small RNA sequencing. Finally, the investigation of the presence of these partitiviruses in a fungal collection revealed that they have no role in the pathogenicity of R. necatrix in avocado or in the avirulence of Entoleuca sp. in this host.
