Identification of Acremonium acutatum and Trichothecium roseum isolated from Grape with White Stain Symptom in Korea

During 2010 and 2012 grape harvest seasons in Gyeonggi-do, Korea, a white stain symptom was observed on the harvested grape fruits in 'Campbell-Early' and 'Kyoho' varieties. In samples collected from the infected vine, two different strains of pathogenic fungi have been found and identified as Acremonium acutatum and Trichothecium roseum based on fungal morphology and nucleotide sequence of int...

Roseocardin, a novel cardiotonic cyclodepsipeptide from Trichothecium roseum TT103.

A new cyclodepsipeptide, designated roseocardin, was isolated from the culture broth of Trichothecium roseum TT103. Roseotoxin B and destruxins A and B were also isolated during the same procedure. The structure of roseocardin was determined by EI-MS, NMR and X-ray crystallographic analysis. Roseocardin as well as the other cyclodepsipeptides were shown to produce positive inotropic effects on ...

Acremonium phylogenetic overview and revision of Gliomastix, Sarocladium, and Trichothecium

Over 200 new sequences are generated for members of the genus Acremonium and related taxa including ribosomal small subunit sequences (SSU) for phylogenetic analysis and large subunit (LSU) sequences for phylogeny and DNA-based identification. Phylogenetic analysis reveals that within the Hypocreales, there are two major clusters containing multiple Acremonium species. One clade contains Acremo...

Characterization and biocontrol ability of fusion chitinase in Escherichia coli carrying chitinase cDNA from Trichothecium roseum.

The antifungal mechanism of mycoparasitic fungi involves fungal cell wall degrading enzymes such as chitinases. Trichothecium roseum is an important mycoparasitic fungus with significant antifungal ability, but studies on chitinases of T. roseum were poor. Here, we report a novel chitinase cDNA isolated from T. roseum by PCR amplification based on conserved chitinase sequences. Southern blot an...
