Five Sporocarpic Species of Glomus Found in Korea

The Korean Journal of Mycology, volume 20, issue 2, 1992, Pages 85~94
Five sporocarpic species of Glomus were found at the four sites of the different plant's cultivations in Korea ; G. clavisporum, G. liquidambaris, G. rubiforme, G. sinuosum, and G. taiwanense. The morphological characteristics of these species collected were observed and compared under light microscopes. Three species G. clavisporum, G. liquidambaris and G. taiwanense were similar with each other in the aspects of having no peridium and the clavate spores orderly arranged within sporocarps. G. sinuosum was different from the other in the aspects of having a thick and sinuous peridium and the orderly arranged spores within sporocarps. However G. rubtforme was different from the other four species in aspects of sporocarps haying ovoid spores arranged irregulary.

Sixty five soil specimens were collected from the nineteen leguminous plant roots throughout 9 sites in four Provinces from Augast 12 to November 21, 1991. VA-mycorrhizal spores isolated from the collected soils were identified and classified into four genera 21 species. However, six spores were newly found and described here: Acaulospora elegans, A. undulata, Glomus laminated spores of. macrocarpus var. macrocarpus, Gl. WUMI%3, Gl. scintillans, Scutellospora verrucosa. Species of three spores that belong to 3 genera; Acaulospora sp., Glomus sp., Scutellospora sp. were unidentified.

Chemotactic responses of five motile saprophytic and one phytopathogenic bacteria e.g. Agrobacterium radiobacter, Bacillus subtilis, B. polymyxa, Pseudomonas aeruginosa, P. fluorescens and Xanthomonas malvacearum towards exudate of Cochliobolus sativus conidia, Fusarium of oxysporum f. sp. ciceri chlamydospores, Macrophomina phaseolina sclerotia and Phytophthora drechsleri f. sp. cajani oospores were determined in vitro at different abiotic conditions. In general, a positive correlation (r=0.76 to 0.89; P=0.05) was observed between concentration of fungal exudates and attraction of bacterial cells. Similarly, a significant (P=0.05; r=+0.82 to 0.95) positive correlation was noticed between chemotactic response and incubation period. The chemotactic response of bacteria was greatly influenced by temperature and pH of the test fungal exudate. The optimum temperature for maximum chemotaxis was
for A. radiobacter,
for B. polymyxa, P. aerugionosa, P. fluorescens and X. malvacearum and
for B. subtilis. Fungal exudates maintained at pH 7 attracted maximum number of bacteria. The response of bacterial cells to exudates at pH 3 and 11 was not significantly (P=0.05) different than that to the buffer (control). Chemotaxis of bacteria was observed towards attractants (fungal propagules and their exudates) when they were kept apart and bridged with the capillaries filled with non-attractant (buffer) or attractant (exudate).
Interspecific Hybridization between Pleurotus cornucopiae and Pleurotus florida Following Protoplast Fusion
Yoo, Young-Bok ;
The Korean Journal of Mycology, volume 20, issue 2, 1992, Pages 118~125
Interspecific fusion products were obtained by protoplast fusion induced by polyethylene glycol, from auxotrophic mutants, Pleurotus cornucopiae and P. florida. The fusants were classified into allodiploidy, stable heterokaryon, and spontaneously segregated heterokaryons. Fruiting body of the clamped or clampless fusants was produced by light-dark cycle on the sawdust medium in glass bottles. Most of these clampless fusants produced mature basidiocarps. The pilei showed various mixed colors resembling the parents. All fruit bodies presented clamp connections except two fusants. When small tissues of stipe from basidiocarps were cultured on a complete medium, mycelial colonies grew more vigorously than that of the original clampless fusants. Five fusants in three crosses were analysed with the distribution of progenies and segregation of genetic characters by random spore analyses. The genetic markers were shown to segregate and recombine in the first generation of monospores isolated from basidiocarps. The analysis indicated the heter-okar-yosis and strong evidence for haploidy of vegetative nuclei, a sexual cycle consisting of nuclear fusion and meiosis. Genotypes of a large number of auxotiophic progenies were not detected. The aberration ratio of segregants indicated the gene interaction resulting from different genome structure between vegetatively incompatible species.
Symbiosis of Arbuscular Mycorrhizae on the Plant Roots
Lee, Sang-Sun ; Ryu, Chang-Neyon ;
The Korean Journal of Mycology, volume 20, issue 2, 1992, Pages 126~133
Using the soils containing several arbuscular mycorrhizae, the degrees of infection on the plant roots were measured with the different level of phosphate added on pot cultures. Infection on the plant roots was independent of the phosphate level for the roots of sorghum, but formation of arbuscular mycorrhizae in the roots was inversely related to the growth of soybean roots. It was concluded that infection of arbuscular mycorrhizae would be related to the phosphate level in the soils. Plants, themselves, were considered to control the infection of arbuscular mycorrhizae under the environments of soils, especially amount of phosphate.
Population Changes of Arbuscular Mycorrhizal Spores in the Different Soil Environments

The association of soil environments and sporulation of arbuscular mycorrhizae was investigated using pot cultures. Increased arbuscular mycorrhizal spores as well as the better growth of the host plants were observed when sorghum (Sorghum bicolor) was treated with different soil conditions using several fertilizers with different concentrations. For to five fold increase of sporulation of arbuscular mycorrhizae was noticed depending on the mycorrhizal species. Although there were some differences between the four arbuscular mycorrhizae species and the conditions of soil environments, maximum populations of spores were reached at about 30-40 days after cultivation. The populations of four arbuscular mycorrhizal species was individually fluctuated. Also, the growth rate of host plants were different from the fertilizers over 2-3 times, but the increase of spores were not influenced by it.
Survey on the Flora and Main Wild Mushroom in Tricholoma matsutake Producing Sites
Na, Jong-Seong ; Ryu, Jeong ;
The Korean Journal of Mycology, volume 20, issue 2, 1992, Pages 144~148
This experiment was carried out to investigate on the flora and cardinal wild mushroom in Tricholoma matsutake producing sites at the Namweon area. The results were as follows: Flora of Tricholoma matsutake producing sites were prevailed over at tree layer (Pinus densiflora S. et. Z.), shrub layer (Rhododendora mucronulatum TURCZ., Quercus serrata THUNB.) and herb layer (Carex humilis LEYSS.). Piedominant wild mushrooms were Boletaceae (Suillusplacidus Bon.) and Ramariaceae (Ramaria botrytis Fr.)
Virus-like Particles from Abnormal Growing Oyster Mushrooms, Pleurotus florida and P. ostreatus
Go, Seung-Joo ; Cha, Dong-Yeul ; Shin, Gwan-Chull ;
The Korean Journal of Mycology, volume 20, issue 2, 1992, Pages 149~153
This study aimed to investigate possible cause of slow and abnormal growth of oyster mushrooms, Pleurotus florida and P. ostreatus collected from bad crop farms. Spherical virus particles of 30 nm in diameter from P. florida, 23 nm particles from P. ostreatus, and both 23 and 30 nm particles were also found from interspecies mated culture between P. florida and P. osreatus. The virus particles might be associated with the bad crop of Pleurotus species.
