“…of structural characteristics of the symbiotic interfaces and the taxonomic identity of the symbionts (Smith & Read 2008). Mycorrhizal plants generally associate with multiple fungal partners, often playing different functions in the symbiosis (Feddermann et al 2010). Molecular methods have been instrumental in revealing/identifying fungi in symbiotic tissues and in the evaluation of genetic and functional fungal diversity.…”

Living organisms establish complex networks of mutualistic and antagonistic interactions in nature, which impact strongly on their own survival and on the stability of the whole population. Fungi, in particular, can shape natural as well as manmanaged ecosystems due to their ubiquitous occurrence and the range of interactions they establish with plants, animals and other microbes. This review describes some examples of mutualistic and antagonistic fungal interactions that are of particular interest for their ecological role, or because they can be exploited by man to improve plant health and/or productivity in sustainable agriculture and forestry.

“…However, further studies will be necessary to elucidate the interaction between the symbionts because research on AMF morphological patterns in acerola crops is nonexistent. Morphological pattern of colonization depends on the plant-AMF combination, according to FEDDERMANN et al (2010). The same authors reported that the plant and AMF genera are not necessarily compatible regarding the morphological pattern of colonization; although, different plant species tend to favor specific colonization morphologies.…”

Morphological pattern of colonization by mycorrhizal fungi and the microbial activity observed in Barbados cherry crops

et al. 2017

Our objective was to evaluate the morphological pattern of colonization by arbuscular mycorrhizal fungi (AMF) as well as to study the microbiological activity of the soil on family farms where Barbados cherry was cultivated. Soil and root samples were selected from four areas in the municipality of Maranguape-CE where Barbados cherry was grown, which were named according to the age of plants in the following manner: A1-3, A2-3, and A3-3 (3 years), and A4-2 (2 years). After sampling, the arbuscular mycorrhizal colonization, morphological colonization pattern, basal soil respiration (SBR), and density of mycorrhizal spores (DS) were analyzed. The Paris-type morphological pattern was predominant in the root system of Barbados cherry; the affinity of this pattern in the culture was clear. Time of installation and management of Barbados cherry orchards in family farming areas promoted reduction in SBR. P levels in the soil may have negatively influenced root colonization and density of mycorrhizal spores.

“…The fungus improves plant P uptake; and, in turn, it absorbs a significant proportion of organic carbon from the host. As a result, AM symbiosis forces plants to develop more the photosynthetic organs than the roots (Feddermann et al, 2010). The opposite response obtained with PGP-HSF inoculation, indicates the lack of nutrient transfer from the fungus to the plant.…”

This is the author's final version of the contribution published as:Dovana, F., Fusconi, A., Berta, G., Camusso, W. AbstractFungi form different types of long-term associations with plants, from mutualistic to pathogenic. Fungal endophytes, which live within host tissues, may confer stress tolerance to the associated plants increasing plant fitness and biomass. In vitro micropropagation and large scale production of aromatic and medicinal plants may benefit from endophyte inoculation. Beside increasing plant growth, fungal endophytes may allow for a reduction of the amount of plant growth regulators in culture media and can be employed to increase the survival rates of micropropagated plants during acclimatization in soil and alleviate the transplantation shock. Previous experiments have shown that a plant growth promoter-hyaline sterile fungus (PGP-HSF) isolated from Mentha piperita L. increased plant growth and influenced the essential oil composition in the same species. In this paper we analysed the SSU rDNA regions of PGP-HSF to determine/confirm its systematic position, which is still uncertain, and investigated the effect of the fungus on in vitro sweet basil (Ocimum basilicum L.) cuttings cultured on a diluted MS medium. The Bayesian and maximum likelihood analysis of SSU rDNA regions confirmed the previously recognized collocation of PGP-HSF in the Sordariomycetes, positioning it as a sister taxon of clade Ophiostomataceae. After 35 days of co-culture of O. basilicum with the fungus, most of the growth parameters were significantly increased. Plant fresh and dry weights, number of leaves, as well as the total leaf area per plant showed an increase greater or equal to 100% in inoculated plants as compared with non-inoculated control plants. The rootto-shoot biomass ratio also increased. These results encourage us to deepen the effects of this endophyte on basil, by studying its influence on the production of essential oils and the post-in vitro culture.
