“…betaine) which are released by the yeasts during their growth. Singh et al [44] reported that yeasts or just their soluble exudates stimulated the percentage of soybean roots colonized by AMF and also the percentage of spore germination and hyphal growth [45]. This occurred particularly when the yeasts were inoculated as an aqueous solution.…”

The new products obtained from natural resources are an alternative to methods based on traditional mineral fertilizers, which are destructive for soil mycorrhizal communities. Our experiment was carried out to evaluate the effect of organic fertilizers and amendments of very diverse composition on mycorrhizal abundance and diversity, as well as on root growth, in strawberry plants cv. "Honeoye". The plants were grown in rhizoboxes filled with a podsolic soil. The plants were treated with granulated bovine manure, vermicompost extract, humates extract, plant extract, extract from seaweed species reinforced with humic and fulvic acids, a consortium of beneficial soil organisms, a stillage from yeast production and a solution of titanium. Plants treated with products and the microorganisms consortium also received half dose of manure. A standard mineral fertilization (NPK) and an unfertilized control were also included. The bioproducts based on humus-like substances and the yeast stillage had the greatest positive influence on the colonization of roots by arbuscular mycorrhizal fungi (AMF). The different treatments affected the diversity of AMF species present in the rhizospheric soil. All organic products, even though providing a significantly low amount of nutrients, enhanced root growth characteristics in comparison to the mineral fertilization.

“…When G. geosporum and R. glutinis coexist in soil without the toxicant present, the fungus species shows a progressive increase in external mycelium development. Singh et al (1991) found that inoculation with yeast cells of Saccharomyces cerevisiae enhances symbiotic parameters such as spore number, formation of vesicles and arbuscules, and colonization. Another response is noted when G. geosporum lives with R. glutinis in soil with phenanthrene.…”

The effect of the polycyclic aromatic hydrocarbon (PAH) phenanthrene and the yeast Rhodotorula glutinis on the arbuscular mycorrhizal fungus (AMF) Glomus geosporum colonizing maize roots, was studied. During a 90-day experiment, the highest G. geosporum colonization values were found in control plants. Mycorrhiza root length, measured both on the basis of percentage of root colonization and on the activity of succinate dehydrogenase, showed similar patterns in different phenanthrene treatments. The presence of phenanthrene in the substrate reduced G. geosporum intraradical colonization. The presence of R. glutinis did not enhance AMF colonization in the presence of phenanthrene. The biomass of the external mycelium estimated on the basis of the fatty acid 16:1 omega 5 concentration showed a progressive increase through time, and the amounts of this fatty acid differed among treated and untreated substrates. However, this increase was found to be lowest in the phenanthrene and Rhodotorula treatment at 60 days. There was less phenanthrene accumulation in roots of maize inoculated with AMF and the yeast than in roots inoculated only with AMF. A similar pattern was observed in the phenanthrene content of G. geosporum spores collected after 90 days.

“…Stimulation of mycorrhiza formation by flavonoids and fungicides as well as by other microorganisms has been reported Singh et al, 1991;Siqueira et al, 1991;von Alten et al, 1993). Synergistic effects of rhizobia on mycorrhiza were thought to be nutritional and restricted to the stage of nitrogen fixation.…”

Rhizobial Nodulation Factors Stimulate Mycorrhizal Colonization of Nodulating and Nonnodulating Soybeans

Legumes form tripartite symbiotic associations with nodule-inducing soil bacteria of the genera Rhizobium, Brudyrhizobium, or Azorkizobium (Caetano-Anollés and Gresshoff, 1991;Hirsch, 1992) and with VAM fungi (BonfanteFasolo, 1987;Koide and Schreiner, 1992). Both the rhizobial and fungal microsymbionts improve the mineral nutrition of the host plant in exchange for assimilates provided by the latter. The nitrogenase enzyme of rhizobia fixes atmospheric nitrogen in the nodules (Thorneley, 1992), and fungal hyphae facilitate the uptake of ions, mainly phosphate, in mycorrhizal roots (Smith and Gianinazzi-Pearson, 1988). In most cases investigated, especially when both nitrogen and phosphate are limiting factors, VAM fungi '
