One of the most important limiting factors of crop growth in the arid and semi-arid regions is water deficit. Mycorrhizal fungi is one of the most important microorganisms in the rhizosphere. The effects of these fungi apply via changes on some of the characteristics of roots and nutrients uptake in host plants under drought conditions. In order to evaluate the effect of arbuscular mycorrhizal ...

Soil microbes play an important role in the biogeochemical cycling of nutrients and their availability to plants, which is for sustaining soil health agricultural sustainability. In light this, vesicular arbuscular mycorrhiza (VAM) plays function. Hyphae VAM can reach far beyond plant root zone, allowing it obtain from a considerably larger region soil. Mycorrhiza improves nutrition by facilita...

Changes in the concentrations of individual flavonoids and polyamines (PAs) in Scots pine (Pinus sylvestris L.) cotyledonary seedlings were studied during the establishment of an ectomycorrhizal (ECM) symbiosis with two Suillus variegatus strains in vitro. Both flavonoids and PAs were analysed after 3, 7, and 14 d in dual culture, and changes in concentrations were compared with growth of the s...

Specific rDNA ITS amplifications, microsatellite-primed PCR and ITS-SSCP analysis were applied to identify and characterize pre-selected isolates of the edible ectomycorrhizal fungus Lactarius deliciosus in different stages of the life cycle. Sampling was performed from pure cultures, mycorrhizas and soil from experimental plots established with nursery-inoculated pine seedlings. A newly-design...

Fungus-derived indole-3-acetic acid (IAA), which is involved in development of ectomycorrhiza, affects both partners, i.e., the tree and the fungus. The biosynthesis pathway, excretion from fungal hyphae, the induction of branching in fungal cultures, and enhanced Hartig net formation in mycorrhiza were shown. Gene expression studies, incorporation of labeled compounds into IAA, heterologous ex...

Arbuscular mycorrhiza fungi (AMF) can colonize the roots of Amorpha fruticosa, a perennial leguminous woody shrub, and form arbuscular mycorrhiza (AM). AMF have significant promoting effects on A. fruticosa growth as the intensity of fungal colonization increases. Taking AMF-A. fruticosa symbionts as the experimental material, gel-free isobaric tags for relative and absolute quantification (iTR...

Eucalyptus obliqua, the most widespread timber tree in Tasmania, is a pioneer after fire which can eliminate the organic layer of forest soil, exposing the underlying mineral soil. We compared seedling growth, mycorrhiza formation, and mineral nutrient limitation in organic layer vs. mineral soil. We grew E. obliqua seedlings separately in pots of organic layer and mineral soil in a glasshouse....

For more than 400 million years, plants have maintained a mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi. This evolutionary success can be traced to the role of these fungi in providing plants with mineral nutrients, particularly phosphate. In return, photosynthates are given to the fungus, which support its obligate biotrophic lifestyle. Although the mechanisms involved in phosph...
