[EN] The present invention relates to the field involved in the recovery of degraded areas, revegetation, production of mycorrhizal inoculants and biofertilisers, ecological agriculture and nursery production. More specifically, the invention relates to a new arbuscular mycorrhizal fungus (AMF) which establishes mycorrhizal symbiosis with the majority of plants of economic and ecological interest (fruit and vegetables, ornamental plants, those used for revegetation, etc.), increasing the survival, vitalityand production thereof, particularly in conditions ofhigh concentrations ofheavy metals and other xenobiotics, and reducing the need for the application of chemical fertilisers, pesticides and phytosanitary products.[ES] La presente invención se encuentra dentro del campo de la recuperación de áreas degradadas, revegetación, producción de inoculantes micorrícicos y biofertilizantes, agricultura ecológica y producción viverística.

Application of the ultimate arbuscular mycorrhizal inoculant MYCOGEL® in Japan: results and prospects

Arbuscular mycorrhizas (AM) are mutualistic symbioses occurring between the vast majority of land plant roots and a reduced group of soilborne fungi, the arbuscular mycorrhizal fungi (AMF). The fungus provides the plant of water and mineral and organic nutrients acquired very efficiently from the soil via fungal hyphae, which enhances plant nutritional status and physiological equilibrium, and results in higher yield and a healthier and more sustainable crop production. However, the obligate biotrophic status of AMF has hampered up to recently the large-scale production and application of AMF as inoculants. Conventional AMF inoculants consist of solid grain or powder substrates mainly containing dormant fungal spores, usually in a too-low percentage and often difficult to detect and verify for their vitality. These inoculants are difficult to apply homogeneously via watering systems, slow to establish symbiosis and, what is worst, usually contain non-desired microorganisms, due to their non-in vitro production and formulation. This situation gave a U-turn ten years ago with the presentation of the first ultrapure, gel-type mycorrhizal inoculant in the world, MYCOGEL®, produced and commercialized in vitro to preserve all its quality and traceability from the lab to the field. MYCOGEL® promotes a very quick and specific AM response to the plant, thus exerting all AM benefits from the beginning of its lifespan, to finally enhance fruit production in terms of amount and quality. In this paper we present the first results obtained in Japan on MYCOGEL® application to different crops in agronomic conditions. Rice, green onion, lettuce, tomato, onion, green pepper, celery and grape were the crops tested, with important increases in crop productivity, quality and yield value. The relative importance of the percentage of mycorrhizal colonization of the roots vs. the agronomic effects observed is also discussed

Arbuscular Mycorrhizal Inoculation Enhances Endurance to Severe Heat Stress in Three Horticultural Crops

Global climate change is increasing temperatures worldwide, which greatly affects all biological relationships. Plant and soil ecosystems are also suffering in this new scenario, especially in semi-arid areas where water resources are limited. Regarding agricultural crops, temperatures that increase dramatically negatively affect fruit production and quality, making it mandatory to find sustainable practices to cope with these new situations. Symbiotic microorganisms in general and arbuscular mycorrhizal fungi in particular have been revealed as promising methods of alleviating stress that are respectful of the environment and soil equilibrium. In this work, we demonstrate the suitability of an ultra-pure, in vitro-issued arbuscular mycorrhizal inoculant for alleviating severe heat stress when applied to three important agricultural crops (tomato: Solanum lycopersicum L.; pepper: Capiscum annuum L.; cucumber: Cucumis sativus L.) under agronomic conditions. Inoculated plants had greatly improved endurance under heat stress because of increased vigor, productivity, and fruit quality. Considering the actual scenario of global climate change, our results shed a light of hope and indicate more sustainable cultivation practices adapted to global change

Inoculation of Indigenous Arbuscular Mycorrhizal Fungi as a Strategy for the Recovery of Long-Term Heavy Metal-Contaminated Soils in a Mine-Spill Area

Symbiotic associations with arbuscular mycorrhizal fungi (AMF) offer an effective indirect mechanism to reduce heavy metal (HM) stress; however, it is still not clear which AMF species are more efficient as bioremediating agents. We selected different species of AMF: Rhizoglomus custos (Custos); Rhizoglomus sp. (Aznalcollar); and Rhizophagus irregularis (Intraradices), in order to study their inoculation in wheat grown in two soils contaminated with two levels of HMs; we tested the phytoprotection potential of the different AMF symbioses, as well as the physiological responses of the plants to HM stress. Plants inoculated with indigenous Aznalcollar fungus exhibited higher levels of accumulation, mainly in the shoots of most of the HM analyzed in heavily contaminated soil. However, the plants inoculated with the non-indigenous Custos and Intraradices showed depletion of some of the HM. In the less-contaminated soil, the Custos and Intraradices fungi exhibited the greatest bioaccumulation capacity. Interestingly, soil enzymatic activity and the enzymatic antioxidant systems of the plant increased in all AMF treatments tested in the soils with both degrees of contamination. Our results highlight the different AMF strategies with similar effectiveness, whereby Aznalcollar improves phytoremediation, while both Custos and Intraradices enhance the bioprotection of wheat in HM-contaminated environments
