Urban parks are ecosystems with a dynamic directed by human intervention. Arbuscular mycorrhizal fungi are symbionts with higher plants, with role in increasing the amount of nutrients needed to plant development. In roots, the fungi develops various structures for transfer or storage of nutrients. The grasses developed in the parks of the Cluj-Napoca city present typical mycorrhizal structures, including the two morphotypes of arbuscules. The colonization rate identified in the analyzed samples is over 75%, indicating a high number of propagules in soil. The dependence of arbuscles is higher to intensity than colonization frequency.

Arbuscular mycorrhiza (AM) fungi are considered as an important factor in predicting plants and ecosystem responses to climate changes on a global scale. The Tibetan Plateau is the highest region on Earth with abundant natural resources and one of the most sensitive region to climate changes. To evaluate the complex response of arbuscular mycorrhizal fungi colonization and spore density to climate changes, a reciprocal translocation experiment was employed in Tibetan Plateau. The reciprocal translocation of quadrats to AM colonization and spore density were dynamic. Mycorrhizal colonization frequency presented contrary changed trend with elevations of quadrat translocation. Colonization frequency reduced or increased in majority quadrats translocated from low to high or from high to low elevation. Responses of colonization intensity to translocation of quadrats were more sensitive than colonization frequency. Arbuscular colonization showed inconsistent trend in increased or decreased quadrat. Vesicle colonization decreased with changed of quadrat from low to high elevations. However, no significant trend was observed. Although spore density was dynamic with signs of decreasing or increasing in translocated quadrats, the majority enhanced and declined respectively in descent and ascent quadrat treatments. It is crucial to understand the interactions between AM fungi and prairie grasses to accurately predict effects of climate change on these diverse and sensitive ecosystems. This study provided an opportunity for understanding the effect of climate changes on AM fungi.

ABSTRACT The low natural fertility of Brazilian soils requires the use of inoculants that facilitate the absorption of nutrients by plants. Arbuscular mycorrhizal fungi such as obligatory biotrophics of active roots perform this function, but access to this resource is limited by the difficulty in producing inoculants. The objective of this study was to investigate the production of AMF inoculants native of soils under different forest covers in Vitória da Conquista, BA, by means of spore quantification, colonization rate and species identification. For this purpose, soils were collected from sites under Mata Nativa (native forest) and plantations of Madeira Nova (Pterogyne nitens) and Eucalyptus, placed into separate 500 mL disposable cups with seeds of Brachiaria sp. and cultivated for five months. Spores were quantified and the AMF species identified in the control soil (without brachiaria) and in the cups cultivated with brachiaria at each month. From the first month, the colonization rate of brachiaria roots was evaluated. The inoculants produced showed differences in the number of spores and species, in the AMF species identified, and in the root colonization rate as a function of the forest cover. Thus, considering the increase in the number of spores, species and colonization over time, the inoculant produced from the soil under native forest was more promising for utilization.

This paper reports the effects of inoculation with arbuscular mycorrhizal fungi on early plant development, field establishment, and crop yield of the olive (Olea europaea L.) cultivar Arbequina. The response of olive plants to the fungi Glomus intraradices (Schenck and Smith) and G. mosseae (Nicol.& Gerd.) Gerdemann & Trappe in different potting mixes was studied in two different nursery experiments. Pre-inoculation with selected arbuscular mycorrhizal fungi prior to transplanting in the field improved plant growth and crop yield up to three years after inoculation. G. intraradices was more efficient at promoting plant growth than both G. mosseae and the native endophytes present in the orchard soil. Inoculation at the time of transplanting enhanced early plant growth in all the field situations studied. Diminishing mycorrhizal effects over time resulted from natural colonization of noninoculated seedlings and related to the native arbuscular mycorrhizal (AM) fungal population of the field soil. Early inoculation of olive seedlings enhances early plant development and crop productivity of olive trees.

Arbuscular mycorrhizal fungi (AMF) that can cause mutualism with higher plants. Some studies showed that the symbiosis of AMF will increase nutrients absorption, the capacity of anti-stress (e.g. drought, salt and disease) by melon (Cucumis melo L.). This study evaluated the roles of proteins on salt-tolerance mechanism after melon was symbiotic with AMF (Funneliformis mosseae). The melons were cultivated in the hydroponic solution containing 0 M, 0.042 M or 0.084 M NaCl for inoculated AMF and non-AMF inoculated seedlings. Root apice of AMF seedling after treating with different NaCl concentrations that were chosen for the estimation of proteins. The results showed that 12 proteins were significantly different after treating with different sodium chlorite (NaCl) concentrations, with proteins that four upregulated and eight downregulated. The tolerance of NaCl stress by root of melon that was inoculated by AMF were attributable to cellular activities involved in carbohydrate metabolism, energy metabolism, production of organic acid, relief of salt injury, which may be critical for promotion of nutrients absorption, anti-stress. This study can offer an important clue to advanced genomic exploration for the inoculation of AMF on different plants.

The peppers business is an important segment of the Brazilian agricultural market, with strong expression in the food, pharmaceutical and cosmetic industries. The objective of this work was to determine the mycorrhizal colonization rate, spore density and mycorrhizal fungi genotypes associated with the rhizosphere of ten lines of chilli peppers (Capsicum frutescens). The experimental design was completely randomized, with 10 treatments and 4 replicates, with the ten strains of Capsicum frutescens: IFET-1121; IFET-1109; IFET-1129; IFET-1119; IFET-1117; IFET-1137; IFET-1131; IFET-1127; IFET-1125 and IFET-1111. The spores of arbuscular mycorrhizal fungi (AMF) will be extracted from the soil using 50 cm³ of each composite sample, using the wet sieving technique. The determination of the percentage of mycorrhizal colonization occurred through the technique of intersection of the quadrants. The identification of mycorrhizal fungi species was by morphological comparison based on the descriptions of the reference cultures present in the International Culture Collection of Arbuscular and Vesicular-Arbuscular Mycorrhizal Fungi. The spore number and mycorrhizal colonization data will be submitted to classical statistical analysis using the Assistat program (2016). The genus Acaulospora, Claroideoglomus, Diversispora, Scutellospora, Sclerocystis, Glomus, Funneliformis and Gigaspora associated with the rhizosphere of the Capsicum frutescens strains were identified. The genera Glomus, acaulosporand Claroideoglomuswere found in all strains analyzed. The IFET - 1127 strain presented higher spore density values when compared to the other strains studied. No significant difference was found in the values of mycorrhizal colonization rate among the investigated strains

Compost and Arbuscular mycorrhizal fungi are environmentally sustainable and low-cost materials that can benefit tropical soils with high phosphorus fixation and low organic matter content. This study investigated the effects of Arbuscular mycorrhizal fungi (AMF) and compost on the growth and nutrient uptake efficiency of sugarcane (Saccharum officinarum) seedlings. The experimental design was a completely randomized factorial design, where factor A (n = 5) was the compost doses (0, 15, 30, 60 and 120 t ha-1) and B (n = 3) the AMF inoculum (Rhizophagus clarus, Gigaspora margarita, and non-inoculated). At 30 and 90 d, seedlings’ diameter and height were measured. Mycorrhizal colonization rate, biomass production, nutrient uptake (P and N), and mycorrhizal dependency were assessed at the end of the experiment. The AMF and compost doses affected the colonization rate, initial growth, biomass production, and nutrient uptake of sugarcane seedlings. Overall, the AMF benefited plant growth at lower doses of compost. R. clarus had a higher impact on the shoot diameter of sugarcane seedlings. Mycorrhizal colonization increased with compost addition only in seedlings inoculated with G. margarita. There was no clear trend among AMF treatments for nutrient uptake. In general, sugarcane seedlings dependency on mycorrhizal condition to produce growth was higher at lower compost doses.

Arbuscular mycorrhizal fungi (AMF) are widely distributed in nature. They live in the roots of higher plants, in a symbiotic relationship. In this study, five commercial species of yams (Dioscoreaspp.) were inoculated with six species of AMF,Glomus clarum,G. etunicatum,G. fasciculatum,Gigasporasp.,G. mosseae, andAcaulosporasp., in field cultivation conditions to investigate the influence of AMF inoculation on tuber weights and secondary metabolite content in yam tubers. The results showed that mycorrhizae formation rates ranged from 63.33% to 90%.G. etunicatuminoculation treatment increased the tube weights of the five species of yam tubers by 39%, 35%, 20%, 56%, and 40% for Tainung 1, Tainung 2, Ercih, Zihyuxieshu, and Tainung 5, respectively. The content of secondary metabolites, such as polyphenols, flavonoids, and anthocyanin, was significantly increased by the AMF treatment in tuber flesh and peel of all the tested yam species. Specifically, the maximums exchange of secondary metabolite contents increased to 40%, 42%, and 106% for polyphenols, flavonoids, and anthocyanin, respectively, in the tuber fresh. This study revealed that different species of yam had varying degrees of affinity with various AMF species; selecting effective AMF species is necessary to facilitate yam growth and improve the quality and quantity of yam tubers.
