| distribution of ectomycorrhizal and pathogenic fungi in soil along a vegetational change from japanese black pine (pinus thunbergii) to black locust (robinia pseudoacacia). | the nitrogen-fixing tree black locust (robinia pseudoacacia l.) seems to affect ectomycorrhizal (ecm) colonization and disease severity of japanese black pine (pinus thunbergii parl.) seedlings. we examined the effect of black locust on the distribution of ecm and pathogenic fungi in soil. dna was extracted from soil at depths of 0-5 and 5-10 cm, collected from the border between a japanese black pine- and a black locust-dominated forest, and the distribution of these fungi was investigated by d ... | 2009 | 19015894 |
| detection of extracellular protease activity in different species and genera of ectomycorrhizal fungi. | in northern forest ecosystems, most soil nitrogen (n) is in organic form and forest trees are largely dependent on ectomycorrhizal (ecm) fungi and their degradative abilities for n uptake. the ability of ecm fungi to acquire n from organic substrates should, therefore, be a widespread trait given its ecological importance. however, little is known about the degradative abilities of most ecm fungi as they remain untested due to problems of isolation or extremely slow growth in pure culture. in th ... | 2007 | 17216502 |
| raman spectroscopic study of lactarius spores (russulales, fungi). | fungi are important organisms in ecosystems, in industrial and pharmaceutical production and are valuable food sources as well. classical identification is often time-consuming and specialistic. in this study, raman spectroscopy is applied to the analysis of fungal spores of lactarius, an economically and ecologically important genus of basidiomycota. raman spectra of spores of lactarius controversus pers.: fr., lactarius lacunarum (romagn.) ex hora, lactarius quieticolor romagn. and lactarius q ... | 2004 | 16165029 |
