dcterms.abstract: Identification of species is crucial in understanding how diversity changes affect ecosystemic processes. Particularly, soil microbial are key factors of ecosystemic functioning .Among soil microbes, arbuscular mycorrhizal fungi (AMF, phylum Glomeromycota) are worldwide distributed and form symbiotic associations with almost 80% of the vascular plants of the earth, except for one species, <i>Geosiphon pyriformis</i>, which associates with the cyanobacteria <i>Nostoc</i>. AMF comprise around 300 morphologically defined or 350–1000 molecularly defined taxa. Since AMF associate with aboveground community, their occurrence and composition can influence ecosystemic processes either through affecting plant community composition and thus its processes rates, or soil microbial communities, which are directly involved in nutrient cycling. Soil microorganisms are considered a potentially suitable target for studying regional and local effects on diversity. The symbiosis with AMF not only increases nutrient uptake by the plant of mainly phosphorus (P) and nitrogen (N) in exchange for plant-assimilated carbon (C), but also improves the tolerance of plants to various biotic and abiotic stresses such as pathogens, salinity, and drought.

dcterms.isPartOf.*: vol. 38, no. 1; Ciencia del Suelo
dcterms.abstract: Estrategias de asociaciones entre plantas con hongos micorrícicos arbusculares (HMA) podrían ser utilizadas para garantizar una eficiente nutrición de fósforo (P). Sin embargo, se desconoce si prácticas usuales de largo plazo destinadas a la producción de soja en nuestro país, han deprimido el potencial de colonización y de promoción de crecimiento vegetal por las comunidades de HMA nativos. Nuestro objetivo fue cuantificar el aporte en crecimiento, absorción de P y partición de fotoasimilados en soja aportados por HMA nativos de monocultivo de soja de larga duración ante oferta diferencial de P. Se instaló un ensayo en invernáculo durante 60 días con 4 tratamientos (con “+“ y sin “-“ HMA nativos de un monocultivo de soja de larga duración instalado en Córdoba; con “+“ y sin “–“ fertilización con P por aplicación semanal de 15,5 mgP maceta-1). Los HMA nativos colonizaron las raíces de soja y favorecieron su crecimiento aun cuando la oferta de P no fue limitante. La colonización micorrícica intra y extra-radical, así como la oferta de P, favorecieron el crecimiento, la acumulación de P y el contenido y la partición de azúcares en las plantas de soja. Las plantas crecidas en presencia de micorrizas (+HMA) sin oferta de P (-P) mostraron mayor acumulación de materia seca y P. Aunque no se evidenció incremento significativo en la absorción de P por las micorrizas, las plantas en la condición +HMA y +P mostraron respuesta positiva a la micorrización en el crecimiento aéreo. Las plantas que crecieron ante +P y -HMA no fueron las de mayor crecimiento. Esto resalta la importancia de favorecer prácticas de manejo que, combinadas con la fertilización moderada destinada a la reposición de nutrientes, favorezca el mantenimiento de poblaciones de HMA nativas que pueden contribuir a un uso más eficiente de la fertilidad del suelo y favorecer el crecimiento del cultivo de soja.; Association strategies between plants and arbuscular mycorrhizal fungi (AMF) could be used to ensure an efficient phosphorus (P) nutrition. However, it is unknown if current long-term practices of soybean crop production depressed potential for indigenous AMF colonization and growth promotion. Our objective was to assess the contribution on growth, P uptake and photo-assimilate partitioning in soybean. A greenhouse trial (60 days) was installed with 4 treatments (with “+“ and without “-“ AMF indigenous from a long-term soybean crop from Cordoba; with “+“ and without “-“ P fertilization by weekly application of 15.5 mg P pot-1). Indigenous AMF colonized soybean roots and favored plants growth even when the P supply was not limiting. The intra and extra-radical presence of AMF as well as the supply of P, favored the growth, the accumulation of P and the content and the partition of sugars in the soybean plants. Plants that grew in the presence of mycorrhizae (+AMF) without P supply (-P) showed increases in dry matter and accumulated P. Although there was no significant increase in the P uptake by mycorrhizae, plants in the +AMF and +P condition showed a positive response to mycorrhizal colonization in their aerial growth. Plants that grew in the -AMF and +P condition did not show higher growth.
This highlights the importance of management practices for soybean crop that, in combination with moderate P fertilization aimed for nutrient replenishment; favor the maintenance of indigenous AMF activities.

dcterms.abstract: In the last two decades, a significant amount of work aimed at studying the ability of the white-rot fungus Coriolopsis rigida strain LPSC no. 232 to degrade lignin, sterols, as well as several hazardous pollutants like dyes and aliphatic and aromatic fractions of crude oil, including polycyclic aromatic hydrocarbons, has been performed.
Additionally, C. rigida in association with arbuscular mycorrhizal fungi appears to enhance plant growth, albeit the physiological and molecular bases of this effect remain to be elucidated. C. rigida's ability to degrade lignin and lignin-related compounds and the capacity to transform the aromatic fraction of crude oil in the soil might be partially ascribed to its ligninolytic enzyme system. Two extracellular laccases are the only enzymatic components of its lignin-degrading system. We reviewed the most relevant findings regarding the activity and role of C. rigida LPSC no. 232 and its laccases and discussed the work that remains to be done in order to assess, more precisely, the potential use of this fungus and its extracellular enzymes as a model in several applied processes.

dcterms.abstract: Objectives: We studied Beauveria bassiana ability to endophytic colonize soybean and its effects on some biological and reproductive parameters and on the food preference of Helicoverpa gelotopoeon, a polyphagous plague of several agronomic crops.
Methods: A suspension of 1x10<sup>8</sup> conidia ml<sup>-1</sup> of B. bassiana (LPSC 1098), was inoculated in soybean plants using the leaf spraying method. H. gelotopoeon survival, developement, fecundity and fertility were registered to evaluate fungal effect. Also, food preference was determined by the free-choice method.
Results: B. bassiana as an endophyte adversely affected the duration of the larval stages (L1, L2, L3, L4) and of the adult stages, as well as the total duration of the life cycle. Furthermore, the oviposition period, fecundity and fertility of H. gelotopoeon decreased. This is the first report of decreased consumption of soybean leaves by H. gelotopoeon due to endophytic B. bassiana.
Conclusions: This investigation shows that endophytic fungi could be considered as useful microorganisms for the integrated pest management

dcterms.abstract: Cadavers are an abundant source of organic matter. During their decomposition, a variety of organisms – insects, bacteria, and fungi – can feed on them. Within the ambit of forensic science, fungi have thus far received little attention. Nevertheless, the current study found that forensic mycology can be developed as a tool that provides useful evidence for case resolution. The fungal biota found growing on the surface of two cadavers with different post-mortem intervals (PMI) was examined and identified. The fungal samples were cultured and identified by morphology and molecular genetics. Fungal species such as Arthrinium arundinis, Aspergillus niger, Aspergillus terreus, Candida guillermondii, Candida lypolitica, Cladosporium cladosporioides, Chrysosporium merdarium, and Scopulariopsis brevicaulis were registered. These findings are the first contributions to forensic mycology from Argentine research. In combination with the joint investigations of forensic researchers worldwide, these results should contribute in the discussion of the use of mycology as a valid forensic tool in which fungi can provide evidence in complex cases.; Les cadavres sont une source abondante de matière organique. Au cours de leur dècomposition, divers organismes - insectes, bactéries et champignons - peuvent s’en nourrir. Dans le domaine de la science médico-légale, les champignons ont jusqu’ici reçu peu d’attention. Néanmoins, la présente étude a révélé que la mycologie médico-légale peut être développ ee comme un outil pouvant fournir des preuves utiles pour la résolution des cas. Le biote fongique trouvé à la surface de deux cadavres avec des intervalles post-mortem différents (PMI) a été examiné et identifié. Les échantillons fongiques ont été cultivés et identifiés par morphologie et génétique moléculaire. Des espèces fongiques telles que: Arthrinium arundinis, Aspergillus niger, Aspergillus terreus, Candida guillermondii, Candida lypolitica, Cladosporium cladosporioides, Chrysosporium merdarium et Scopulariopsis brevicaulis ont été identifiées. Ces résultats sont les premières contributions à la mycologie médico-légale d’une recherche argentine. Ces résultats, en complément aux enquêtes conjointes de chercheurs en médecine légale du monde entier, devraient contribuer à la discussion sur l’utilisation de la mycologie en tant qu’outil médico-légal valide dans lequel les champignons peuvent fournir des preuves dans des cas complexes.

dcterms.abstract: Fungal deterioration of building materials causes economic losses due to restoration processes and because it affects the health of the people exposed.
Therefore, it is necessary to obtain highly deteriorating fungal strains to carry out studies focused on biodeterioration control. The aim of this research was to study the mycobiota involved in deterioration of facades through the isolation and characterization of fungal strains. In this sense, this paper characterizes the mycobiota that contributes to the deterioration of brick and concrete present in those places. Samples were taken from bricks and concrete with visible biodeterioration of the Cathedral of La Plata and the Experimental Station of the Centro de Investigación y Desarrollo en Tecnología de Pinturas. Relative density, apparition relative frequency, and ecological category of fungi isolates were determined. The deteriorating attributes were determined by carbonate dissolution test, pigment secretion assay, acid production test and brick weight variation. Cladosporium sp., Penicillium sp. and Aspergillus sp. were the taxa with the highest apparition relative frequency and abundance. Aspergillus niger MN371276, Lasiodiplodia theobromae MN371283, Cladosporium sphaerospermum MN371394, Penicillium commune MN371392 and Arthothelium spectabile MT071822 were the strains with the highest biodeteriorant activity. These strains can be used in studies on biodeterioration control of buildings materials.

dcterms.abstract: The agricultural expansion has leaded to increase the irrigated cropland area and the use of fertilizers, resulting in water degradation, increased energy use, and common pollution. Of particular concern is the increased interest to reduce the environmental impacts of high quantities of water dedicated to irrigation by agricultural activities We are now truly recognizing the importance of sustainable measures in agriculture such as conservation of the vegetation cover and management approach to understand surface and deep soil responses to global change. The agroecology management based on key processes from natural ecosystems can help to solve some agricultural difficulties. Increasing studies on the Arbuscular mycorrhizal fungi (AMF) has showed their importance for soil ecology and studies on their biodiversity have spread in some agro-ecosystems such as corn and soybean monocultures. Therefore, it is needed to deeply study the mycorrhizal functions under global change. In this chapter, we examine the major developments and advances on mycorrhizal fungi based on recent research from South American countries. New reports on the occurrence of mycorrhizas in Amazonian dark earth, as well as the inoculum production of arbuscular mycorrhizal fungi native of soils under native forest covers, have resulted in a more detailed understanding of the soil biology from South America. Reports from Amazonian dark earth or “Terra preta do índio” soil has stimulated the use of biochar worldwide as a soil conditioner that can add value to non-harvested agricultural products and promote plant growth. Few reports from Brazil showed that the addition of inorganic fertilizer, compost and chicken manure resulted in increases in plant cover and plant species richness. In this sense, the biochar/mycorrhizae interactions also can be prioritized for sequestration of carbon in soils to contribute to climate change mitigation.
