Using a Novel Partitivirus in Pseudogymnoascus destructans to Understand the Epidemiology of White-Nose Syndrome.

White-nose syndrome is one of the most lethal wildlife diseases, killing over 5 million North American bats since it was first reported in 2006. The causal agent of the disease is a psychrophilic filamentous fungus, Pseudogymnoascus destructans. The fungus is widely distributed in North America and Europe and has recently been found in some parts of Asia, but interestingly, no mass mortality is observed in European or Asian bats.

Taxonomy and phylogenetic relationships of nine species of Hypocrea with anamorphs assignable to Trichoderma section Hypocreanum.

Morphological studies and phylogenetic analyses of DNA sequences from the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of the large exon of tef1 (LEtef1) were used to investigate the taxonomy and systematics of nine Hypocrea species with anamorphs assignable to Trichoderma sect. Hypocreanum. Hypocrea corticioides and H.

Systematics of Hypocrea citrina and related taxa.

Morphological studies and phylogenetic analyses of DNA sequences from three genomic regions - the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of translation elongation factor (tef1) - were used to investigate the systematics of Hypocrea citrina and related species. A neotype specimen is designated for H. citrina that conforms to Persoon's description of a yellow effuse fungus occurring on leaf litter.

Development of a Real-Time RT-PCR SYBR Green Assay for Tomato ring spot virus in Grape.

Grapevines infected with Tomato ring spot virus (ToRSV) pose an economic risk for growers in the northeastern United States. This study describes a one-step real-time reverse-transcription polymerase chain reaction (RT-PCR) SYBR Green assay for detecting ToRSV in grapevines. Two newly designed primer pairs based on the ToRSV coat protein gene sequence were evaluated for specificity and optimized for a SYBR Green assay.

Hypocrea/Trichoderma: species with conidiophore elongations and green conidia.

Species of Trichoderma and Hypocrea that have green conidia and sterile or fertile elongations of their conidiophores are described or redescribed and their phylogenetic position explored. The described species include T. crassum, T.
