Plants growing in the soils of karst forests associate with arbuscular mycorrhizae (AM) or ectomycorrhizae (ECM) to acquire nutrients. We researched how these different mycorrhizal associations affect rhizosphere soil nutrient economy calcareous soils. Bulk and were sampled beneath 25 AM 9 ECM plants primary at Puding Karst Critical Zone Observatory. Nutrient contents potential enzyme activitie...

Compost tea is a liquid organic amendment that has been reported to benefit plant growth and performance through positive effects on microbial communities nutrition. However, few studies have demonstrated this for containerized plants produced in tree nurseries. Five common urban species (Acer negundo, Corymbia maculata, Ficus platypoda, Hymenosporum flavum, Jacaranda mimosifolia) were grown ex...

Ericaceae are a group of plants with biotechnological and commercial importance. These establish symbiotic associations wide mycorrhizal fungi. National global studies have focused on two them: arbuscular endomycorrhizae ectomycorrhizae. The most recent type mycorrhiza recorded is the cavendishioid ectendomycorrhizae. one least-studied understood mycorrhizae, along monotropoid arbutoid mycorrhi...

We have assembled a sequence database for 80 genera of Basidiomycota from the Hymenomycete lineage (sensu Swann & Taylor 1993) for a small region of the mitochondrial large subunit rRNA gene. Our taxonomic sample is highly biased toward known ectomycorrhizal (EM) taxa, but also includes some related saprobic species. This gene fragment can be amplified directly from mycorrhizae, sequenced, and ...

Paper birch (Betula papyrifera Marsh) seedlings were grown in a greenhouse in either subsoil or topsoil in factorial combination with two fertilization and drought regimes to investigate how different soil environments and nutrient availability drive belowground partitioning between growth, secondary metabolism and ectomycorrhizal (EM) associations, and impact drought tolerance of paper birch. ...

The ectomycorrhizal fungi Cenococcum geophilum, Hebeloma crustuliniforme, and Laccaria laccata produced ethylene in vitro in modified Melin-Norkrans liquid medium only if amended with 2.5-10mM methionine; Pisolithus tinctorius failed to produce ethylene unless the cultures were renewed with fresh methionine-amended medium before ethylene assay. An additional 19 ectomycorrhizal fungi, plus five ...

Ectomycorrhizae are formed by mutualistic interactions between fungi and the roots of woody plants. During symbiosis the two organisms exchange carbon and nutrients in a specific tissue that is formed at the contact between a compatible fungus and plant. There is considerable variation in the degree of host specificity among species and strains of ectomycorrhizal fungi. In this study, we have f...

More than 95 % short roots of most terrestrial plants are colonized by mycorrhizal fungi as soon as they emerge in the upper soil profiles. The establishment of mycorrhizal association involves profound morphological and physiological changes in root and fungus. It is affected by other rhizospheric microorganisms, specifically by the bacteria. Bacteria may have developed mechanisms of selective...
