Fungi play crucially important roles in the biosphere, mediating many ecological processes. Despite this, fungal diversity natural habitats is poorly known. Using newly designed fungal-specific polymerase chain reaction (PCR) primers ([1][1]), we examined total a
SUMMARY Subterranean clover ( Trifolium subterraneum L.) in symbiosis with Glomus mosseae (Nicol. & Gerd.) Gerdemann Trappe was grown compartmented pots. Side compartments were filled soil where recently added (1 wk) radio‐labelled cadmium (Cd) at three levels of non‐labelled Cd could be accessed by either roots or arbuscular mycorrhizal hyphae. All treatments replicated non‐mycorrhizal plants. After a growth period 52 d and shoots analysed for 109 Cd, lengths hyphae respective labelled...
Phytoremediation of organic pollutants depends on plant-microbe interactions in the rhizosphere, but extent and intensity such rhizosphere effects are likely to decrease with increasing distance from root surface. We conducted a time-course pot experiment measure dissipation polycyclic aromatic hydrocarbons (PAHs) clover ryegrass grown together two industrially polluted soils (containing 0.4 2 g kg(-1) 12 PAHs). The impact fungal symbiosis arbuscular mycorrhiza (AM) PAH degradation was also...
Phytoremediation of soils polluted with polycyclic aromatic hydrocarbons (PAHs) has so far neglected the possible role ubiquitous symbiotic associations between plant roots and fungi known as arbuscular mycorrhizas. A time course laboratory experiment clover ryegrass grown on spiked [500 + 500 50 mg kg-1 anthracene, chrysene dibenz(a,h)anthracene] soil demonstrated for first that dissipation condensed PAHs may be enhanced in presence mycorrhiza [66 42% reductions dibenz(a,h)anthracene,...
Abstract The weathering of minerals within the rhizosphere has been demonstrated many times; however, only a few studies have concerned directly with root‐microorganism interactions. This study was conducted to determine influence symbiotic (mycorrhizal) and nonsymbiotic microorganisms on rhizospheric mica. A lysimetric experiment performed in greenhouse mica (phlogopite) by roots pine ( Pinus sylvestris L.). Pine were inoculated or not an acid‐producing rhizobacteria Agrobacterium sp.)...
Summary To determine whether the diversity of phenanthrene‐degrading bacteria in an aged polycyclic aromatic hydrocarbon (PAH) contaminated soil is affected by addition plant root exudates, DNA stable isotope probing (SIP) was used. Microcosms with and without ryegrass exudates 13 C‐labelled phenanthrene (PHE) were monitored over 12 days. PHE degradation slightly delayed presence added exudate after 4 days incubation. After days, 68% disappeared both exudate. Carbon balance using isotopic...
Numerous studies address the distribution and diversity of dark septate endophytes (DSEs) in literature, but little is known about their ecological role effect on host plants, especially metal-polluted soils. Seven DSE strains belonging to Cadophora, Leptodontidium, Phialophora Phialocephala were isolated from roots poplar trees sites. All developed a wide range carbohydrates, including cell-wall-related compounds. The evenly colonized birch, eucalyptus ryegrass re-synthesis experiments....
The polycyclic aromatic hydrocarbon (PAH) contamination, bacterial community, and PAH-degrading bacteria were monitored in aged PAH-contaminated soil (Neuves-Maisons [NM] soil; with a mean of 1,915 mg 16 PAHs.kg(-1) dry weight) the same previously treated by thermal desorption (TD 106 weight). This study was conducted situ for 2 years using experimental plots two soils. NM colonized spontaneous vegetation (NM-SV), planted Medicago sativa (NM-Ms), or left as bare (NM-BS), TD (TD-Ms)....
