Rhizopus oryzae is reported for the first time on Cucumis melo L. var. makuwa Makino. A detailed description of this Korean specimen is given, along with its rDNA internal transcribed spacer sequence. On the basis of mycological characteristics and molecular data, the fungus was identified as R. oryzae Went & Prinsen Geerligs.

Alternaria porri causing purple blotch disease of onion is a destructive phytopathogen which causes severe loss in productivity. The present study aimed to unravel the antagonistic potential and efficacy volatile organic compounds produced by various Trichoderma spp. against A. through Gas chromatography-mass spectrometry (GCMS) analysis. Ten isolates species were isolated from rhizospheric soi...

Gray mold of blueberry caused by Botrytis sp. is reported for the first time in Korea. A detailed description of the fungus is given, along with its rDNA internal transcribed spacer sequence. The fungus was identified as Botrytis cinerea based on mycological characteristics and molecular data.

Black yeasts morphologically identified as Exophiala cf. spinifera were re-analyzed on the basis of morphology, nutritional physiology and ITS rDNA sequencing data. Ribosomal small subunit (SSU) DNA sequence data confirmed that strains belonged to a clade containing the ex-type strain of E. spinifera. Variation in the Internal Transcribed Spacer (ITS) region of the rDNA was studied within this ...

Two strains of the mushroom Pleurotus, isolated from nature in Vietnam and Japan, contained a similar combination of two distinct rDNA internal transcribed spacer (ITS) sequences. They were perhaps hybrid dikaryons between P. cystidiosus subsp. abalonus and a novel P. cystidiosus subspecies. These mushrooms produce dikaryotic arthroconidia. This unique asexual reproduction might allow stable ma...

The anisakid nematodes morphologically corresponding with Pseudoterranova decipiens sensu lato (s.l.) (Krabbe, 1878) from different seal or sea lion hosts and geographical origins, previously identified as Pseudoterranova krabbei, P. decipiens (s.s.), P. bulbosa, P. azarasi and P. cattani by multilocus enzyme electrophoresis, were characterized using a DNA approach. Also a population of P. deci...

The application of nuclear rDNA ITS sequences in plant phylogeny and evolution analysis was discussed in this paper. Nuclear rDNA is an important nuclear gene fragment, which had been widely used in phylogenetic studies. The internal transcribed spacer of nuclear rDNA was divided into ITS1 and ITS2 by 5.8S rDNA. The length of ITS1 ranges from 165 bp to 298 bp in angiosperms, and the length of I...

sooty blotch and flyspeck occur on fruit surfaces and result in economic losses due to less attractive appearance. sooty blotch fungi form dark mycelial mats whereas flyspeck fungal agents are well characterized with black, sclerotium-like bodies on fruit surface. whilst more than 60 species have been reported in association with these two fungal diseases, thus far they have not been studied in...

In the present study, a phylogenetic analysis was undertaken based on the internal transcribed spacer (ITS) rDNA and partial β-tubulin gene sequence of the Ganoderma species. The size of the ITS rDNA regions from different Ganoderma species varied from 625 to 673 bp, and those of the partial β-tubulin gene sequence were 419 bp. Based on the results, a phylogenetic tree was prepared which reveal...
