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...

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...

The plant-parasitic nematode, Neotylenchus linlordi, congregated around colonies or filtrates from mycelia of Gliocladium roseum, Rhizoctonia solani, Pyrenochaeta terrestris and Chaetomium indicum. The average time required for the nematodes to reach the fungal colonies ranged from less than 4 hr for G. roseum to 20 hr for R. solani. Nematodes first circled near the point of introduction, then ...

In order to enrich the phylogenetic diversity represented in the available sequenced bacterial genomes and as part of an "Assembling the Tree of Life" project, we determined the genome sequence of Thermomicrobium roseum DSM 5159. T. roseum DSM 5159 is a red-pigmented, rod-shaped, Gram-negative extreme thermophile isolated from a hot spring that possesses both an atypical cell wall composition a...

Allium roseum L. (Alliaceae) endemic mediterranean specie was represented in the North Africa by 12 different taxa. In the present study, chemical composition, antiproliferative, antioxidant and antimicrobial activities of the essential oil extracted from A. roseum var. grandiflorum Briq. bulbs collected in the North of Tunisia were investigated. Chemical characterization has shown methyl metha...

Z. Naturforsch. 55c, 5 2 8 -5 3 3 (2000); received April 5/April 20. 2000 Pelargonium Species, Umckaloabo, Coumarins, Oxygenation Pattern The coumarin patterns of Pelargonium sidoides DC. and Pelargonium reniforme CURT., forming the origin of the herbal medicine “umckaloabo”, were analysed and compared for therapeutic equivalence. For both species, members of triand tetraoxygenated coumarins al...
