| a caryophyllene-related sesquiterpene and two 6, 7-seco-caryophyllenes from liquid cultures of hebeloma longicaudum | three new caryophyllene-related sesquiterpenes, hebelophyllenes d (1), e (2), and f (3), were isolated from liquid cultures of the ectomycorrhizal fungus hebeloma longicaudum. their structures were determined by modern spectroscopic methods. hebelophyllene d has a tricyclo[5.4.0.0(2,5)]undecane skeleton, while hebelophyllenes e and f are the first naturally occurring 6,7-seco-caryophyllenes. | 1999 | 10096864 |
| organic anion exudation by ectomycorrhizal fungi and pinus sylvestris in response to nutrient deficiencies. | low molecular weight organic anions (lmwoa) can enhance weathering of mineral grains. we tested the hypothesis that ectomycorrhizal (ecm) fungi and tree seedlings increase their exudation of lmwoa when supply of magnesium, potassium and phosphorus is low to enhance the mobilization of mg, k and p from mineral grains. ectomycorrhizal fungi and pinus sylvestris seedlings were cultured in symbiosis and in isolation on glass beads with nutrient solution or with sand as a rooting medium, with a compl ... | 2006 | 16539612 |
| genetic diversity of naturally established ectomycorrhizal fungi on norway spruce seedlings under nursery conditions. | we have assessed ectomycorrhizal fungi colonizing norway spruce (picea abies l.) seedlings in nine forest nurseries using restriction fragment length polymorphism (rflp) and sequencing analyses of the internal transcribed spacers (its1-5.8s-its2) amplicons. restriction analysis of the amplified dna fragments with hinfi, mboi, and taqi enzymes allowed the definition of 17 rflp genotypes; five of them could be unambiguously assigned to thelephora terrestris, hebeloma longicaudum, h. crustuliniform ... | 2006 | 16826321 |
