ABSTRACT Disturbance of natural plant communities is the first visible indication a desertification process, but damage to physical, chemical, and biological soil properties known occur simultaneously. Such degradation limits reestablishment cover. In particular, causes disturbance plant-microbe symbioses which are critical ecological factor in helping further growth degraded ecosystems. Here we demonstrate, two long-term experiments desertified Mediterranean ecosystem, that inoculation with...
Development of biological control for plant diseases is accepted as a durable and environmentally friendly alternative agrochemicals. Arbuscular mycorrhizal fungi (AMF), which form symbiotic associations with root systems most agricultural, horticultural hardwood crop species, have been suggested widespread potential bioprotective agents. In the present study ability two AMF (Glomus mosseae Glomus intraradices) to induce local or systemic resistance Phytophthora parasitica in tomato roots...

Arbuscular mycorrhizal (AM) symbioses are mutualistic associations between soil fungi and most vascular plants. The symbiosis significantly affects the host physiology in terms of nutrition stress resistance. Despite lack range specificity interaction, functional diversity AM fungal species exists. interaction is finely regulated according to plant characters, hormones believed orchestrate modifications plant. Using tomato as a model, an integrative analysis response different was performed...
ABSTRACT High concentrations of heavy metals have been shown to adversely affect the size, diversity, and activity microbial populations in soil. The aim this work was determine how diversity arbuscular mycorrhizal (AM) fungi is affected by addition sewage-amended sludge containing a long-term experiment. Due reduced number indigenous AM fungal (AMF) propagules experimental soils, several host plants with different life cycles were used multiply fungi. Six AMF ecotypes found showing...
The effect of the extraradical mycelium arbuscular mycorrhizal (AM) fungus Glomus intraradices Smith & Schenck on nitrate uptake and pH medium was studied in a monoxenic culture with tomato (Lycopersicon esculentum Mill. var. Vendor) roots obtained from root organ culture. symbiosis established compartmented Petri dishes containing agar media amended indicator bromocresol purple. A pattern changes revealed as progressed dish compartments dual, arbuscular-mycorrhizal fungi/root, well hyphae,...
The present work describes the morphogenesis and cytological characteristics of ‘branched absorbing structures’ (BAS, formely named arbuscule‐like structures, ALS), small groups dichotomous hyphae formed by extraradical mycelium arbuscular mycorrhizal (AM) fungi. Monoxenic cultures AM fungus Glomus intraradices Smith & Schenck tomato ( Lycopersicum esculentum Mill.) roots allowed continuous, non‐destructive study BAS development. These structures were not observed in axenic under...
Arbuscular mycorrhizal fungi, obligate symbionts of most plant species, are able to accumulate heavy metals, thereby, protecting plants from metal toxicity. In this study, the ultrastructural localization Zn, Cu, and Cd in extraradical mycelium spores arbuscular fungus Glomus intraradices grown monoxenic cultures was investigated. Zinc, or applied final concentrations 7.5, 5.0, 0.45 mmol/L, respectively. Samples were collected at time 0, 8 h, 7 days after application prepared for rapid...
S ummary A technique using 15 N‐labelled inorganic fertilizer was applied to estimate N 2 fixation by the forage legume Hedysarum coronarium L. and ascertain role of vesicular‐arbuscular (VA) mycorrhizas in plant nutrition throughout a growing season under field conditions. The absence specific Rhizobium for test soil allowed us use methodology with same as reference ‘non‐fixing’ crop. At first harvest, mycorrhizal inoculation behaved similarly phosphate addition improving percentage (70 %)...
Glomus mosseae , a representative species of Endogonaceae (Phycomycetes) able to form vesicular-arbuscular mycorrhiza, was investigated for phytohormone production. Spores G. were axenically germinated in water, and the resultant mycelial growth assayed by standard procedures extracting plant hormones from microbial cultures. Paper partition chromatography specific bioassays used separate identify growth-regulating substances. The microorganism synthesized at least two gibberellin-like...
