Understanding the molecular mechanisms of pathogenesis is useful in developing effective control methods for fungal diseases. The white root rot fungus Rosellinia necatrix is a soilborne pathogen that causes serious economic losses in various crops, including fruit trees, worldwide. Here, using next-generation sequencing techniques, we first produced a 44-Mb draft genome sequence of R. necatrix strain W97, an isolate from Japan, in which 12,444 protein-coding genes were predicted. To survey… Expand
Transcriptome analysis of the fungal pathogen Rosellinia necatrix during infection of a susceptible avocado rootstock identifies potential mechanisms of pathogenesis
TLDR
The analysis of the full-length transcriptome of R. necatrix during the infection process is suggesting that the success of this fungus to infect roots of diverse crops might be attributed to the production of different compounds which, singly or in combination, interfere with defense or signaling mechanisms shared among distinct plant families.

Transcriptional Responses of Sclerotinia sclerotiorum to the Infection by SsHADV-1
TLDR
Details are provided into the effects of SsHADV-1 infection on the whole genome transcription in S. sclerotiorum and the expression of antiviral RNA silencing and virulence factor genes are suppressed. Expand
Advances in Understanding Defense Mechanisms in Persea americana Against Phytophthora cinnamomi
TLDR
Recent advances such as composite plant transformation, single nucleotide polymorphism (SNP) analyses as well as genomics and transcriptomics will complement existing molecular, histological, and biochemical assay studies and further elucidate avocado defense mechanisms. Expand
Diverse Partitiviruses From the Phytopathogenic Fungus, Rosellinia necatrix
TLDR
The characterization of 20 partitiviruses from 16 R. necatrix strains belonging to 15 new species and the identification of a probable reassortment event and a quintuple partitvirus infection of a single fungal strain provide a foundation for further studies aimed at elucidating mechanisms behind the differences observed.

Identification of Rosellinia species as producers of cyclodepsipeptide PF1022 A and resurrection of the genus Dematophora as inferred from polythetic taxonomy
TLDR
The results of this first HPLC profiling were largely inconclusive regarding the utility of secondary metabolites as genus-specific chemotaxonomic markers, but the phylogeny clearly showed that species featuring a dematophora-like asexual morph were included in a well-defined clade, for which the genus Dem atophora is resurrected.

Molecular Characterization of a Novel Polymycovirus From Penicillium janthinellum With a Focus on Its Genome-Associated PASrp
TLDR
Density gradient ultracentrifugation of the PASrp-associated PjPmV1 dsRNA revealed its uneven structure and a broad fractionation profile distinct from that of typical encapsidated viruses, discussed in view of the diversification of genomic segment numbers of the genus Polymycovirus. Expand
Proof of Concept of the Yadokari Nature: a Capsidless Replicase-Encoding but Replication-Dependent Positive-Sense Single-Stranded RNA Virus Hosted by an Unrelated Double-Stranded RNA Virus
Viruses typically encode their own capsids that encase their genomes. However, a capsidless positive-sense single stranded RNA [(+)ssRNA] virus, YkV1, depends on an unrelated double-stranded RNAExpand
