The meals from many oilseed crops have potential for biofumigation due to their release of biocidal compounds such as isothiocyanates (ITCs). Various ITCs are known to inhibit numerous pathogens; however, much less is known about how the soil microbial community responds to the different types of ITCs released from oilseed meals (SMs). To simulate applying ITC-releasing SMs to soil, we amended ...

ABSTRACT- Desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. A PCR-based method was developed for the identification of 3 major desert truffles of Iran: Terfezia claveryi, Tirmania pinoyi and Tirmania nivea based on internal transcribed spacers of rDNA. Two specific PCR primers were designed for T. claveryi, 4 for T. pinoyi, and 2 for ...

Soil is considered as the most complex media of microbial inhabitants including fungi. Soils differ in chemical composition and support the growth of specific fungal flora, however, majority of the soil fungi are autochthonous being indigenous to soil environment. Some of the soil fungi are associated with human and animal diseases and cause chronic problems. The soil containing keratin materia...

Soil acidity is a major constraint on plant productivity. Arbuscular mycorrhizal (AM) fungi support plant colonization in acidic soil, but soil acidity also constrains fungal growth and diversity. Fungi in extreme environments generally evolve towards specialists, suggesting that AM fungi in acidic soil are acidic-soil specialists. In our previous surveys, however, some AM fungi detected in str...

Arbuscular mycorrhizal fungi (AMF) are soil-borne that form mutualistic symbiosis with plant roots, and can signifi cantly improve nutrient uptake increase resistance to several biotic abiotic stresses. Though most rice cultivation systems involved submerged growing conditions, researchers exploring the potential of AMF colonization its benefi ts for rice. has a serving as biocontrol agent in p...

It has been noted previously that nutrient-stressed plants generally release more soluble carbohydrate in root exudates and consequently support more mycorrhizae than plants supplied with ample nutrients. Fertilization may select strains of vesicular-arbuscular mycorrhizal (VAM) fungi that are inferior mutualists if the same characteristics that make a VAM fungus successful in roots with a lowe...

Abstract Aims Plant–soil feedback (PSF) is a key mechanism that can facilitate tree species coexistence and diversity. Substantial evidence suggests species-specific soil-borne pathogens around adult trees limit the performance of home (conspecific) seedlings relative to foreign (heterospecific) seedlings. However, underlying remains largely elusive. Methods Here, we conducted reciprocal transp...
