rhizal fungi with narrow host ranges, their specific host species, such as Pinaceae plants hosting Suillaceae ectomy-corrhizal fungi [21], will dominate the plant community through positive plant–soil feedback [20, 22]. Meanwhile, endophytic and arbuscular mycorrhizal fungi with broad host ranges [23–25] may diminish such negative and posi-

mycorrhizal interactions, because of their high economic and ecological significance and their application potential. Arbuscular mycorrhizal fungi colonize the roots of many agriculturally important food and bioenergy crops and could serve as 'biofertilizers and bioprotectors' in environmentally sustainable agriculture.

taxonomic and ecological groups, from bacteria through collembolans and mites (Scheu & Folger, 2004; Schneider et al., 2005), but there is also an intriguing opportunity that some EcM and possibly also other mycorrhizal fungi could actually recycle C from dead mycorrhizal hyphae in the soil (see chapter 23 for more details).

Two major forms of mycorrhizas are usually recognized: the arbuscular mycorrhizas (AMs) and the ectomycorrhizas (ECMs). Arbuscular mycorrhizal symbiosis is the most widespread mycorrhizal association type and is fundamental in optimizing plant fitness and soil quality[11]. Particularly, the AM symbioses

Other fungal structures were also observed. Fungal structures were observed in bryophyte stem and leaf tissues, and in rhizoids. The AM association with bryophytes was observed to be symbiotic. Key words: arbuscular mycorrhizal fungi, bryophyte, hepatics, moss, symbiosis. Environmental

However, fungal protease are more promising for commercial application as these microorganism are more heir habitats. Fungal species are competent in expression of enzymes in psychrophilic, mesophilic and thermophilic conditions. In last few decades, psychrophilic and thermophilic enzymes were identified for their commercial potential worldwide. Several fungal strains have been isolated and .

Fungal community composition correlated with gross nitrification rate, with 43% of the variation in gross nitri-fication rate attributable to soil fungal abundance. Conclusions Changes in soil fungal community caused by bamboo invasion into broadleaf forests were closely linked to changed soil organic C chemical composition

- Hyphae can be septate or coenocytic. In septate hypha, the structure is divided into cells by septa (like a wall). The septa walls have openings to allow organelles to flow between them. Coenocytic hyphae lack these divisions between cells. Due to the lack of septa, coenocytic hypha is a mass of cytoplasm with hundreds of nuclei

antimicrobial properties were determined. The results obtained suggest that F. equiseti, P. medicaginis, T. asperellum, and T. virens of M. cordata harness bioprospective values as natural drug candidates. This is the first report on isolation and evaluation of the antimicrobial properties of endophytic and rhizosphere fungi of Mikania cordata. 1.

Because agriculture is a source of phosphate pollution in the environment, increased phosphorus uptake by mycorrhizal plants can help reduce the quantity of this nutrient to be added to the soil, and decrease the accumulated P in soil and water. The reduction in the occurrence of disease in mycorrhizal plants is a factor which needs

these mycorrhizas is largely attributed to soil types and N source (Read & Perez-Moreno 2003). Numerous excellent reviews related to mycorrhizal nutrient dynamics and their response to environmental change have been published (Read & Perez-Moreno 2003, Johnson et al. 2013, Phillips et al. 2013).

study is to ascertain the comparative effect of mycorrhizal inocula (autochthonous or allochtho-nous) and P fertilizers (two levels), and to verify the relevance of the AM strain origin or P-fertilizer to the ability to enhance plant growth, nutrition, biochemical antioxidant values related to drought tolerance under semiarid conditions.

Fungal Biology (4th edition) is the successor to three pre-vious editions of “Modern Mycology.” The text has been fully updated and expanded to cover many new devel-opments in fungal biology. Each of the 17 chapters is largely independent, with a clear theme and cross-referencing, so that the text can be used to focus on selected topics.
