“…Approximately, 65% of the soils of the Amazon lowlands in Peru are classified as ultisols, characterized by being extraordinarily acidic and having low availability of phosphorus [50]. The pH can exert a fundamental influence on the composition and diversity of bacteria and fungi living in the soil, owing to its direct impact on the regulation and mobilization of several essential nutrients [23,51]. In this context, AM symbiosis constitutes a key strategy to help plants efficiently take up phosphorus from the soil [52].…”

“…Subsequently, a two-step PCR (using gDNA) was conducted to amplify the ribosomal fragment of AMF consisting of partial SSU, ITS1, 5.8S, ITS2, and partial LSU rDNA using the primers SSUmAf/LSUmAr and SSUmCf/LSUmBr, consecutively [42]. The PCR was carried out according to Corazon-Guivin et al [23,[28][29][30][31][32][33][34]. PCR products from the second round of amplifications (∼1500 bp) were separated by electrophoresis on 1.2% agarose gel, stained with Diamond™ Nucleic Acid Dye (Promega), and revealed by UV illumination.…”

“…Root colonization by AMF is characterized by presenting fungal structures, such as mycelium, auxiliary cells, arbuscules, vesicles, and spores [18,19], being this vast structure it is most important for its correct identification using the morphological approach [18][19][20][21][22]. Currently, in the Peruvian Amazon, some studies have recorded a great diversity of AMF [23][24][25][26][27]. New species were identified in different crops [23,[28][29][30][31][32][33][34][35][36][37][38] using morphological and molecular tools [39][40][41], and molecular analyses of the SSU-ITS-LSU region of rDNA [42].…”

Myrciaria dubia (Kunth) McVaugh (camu-camu) is a shrub native to the Amazon region that produces fruits with a high content of vitamin C and various bioactive compounds, making it a functional food with antioxidant, anti-inflammatory, and antimicrobial properties. However, it is unknown which microorganisms are associated with its root system and can influence its growth and productivity. Arbuscular mycorrhizal fungi (AMF) are associated with most plants and are essential for their establishment, survival, and productivity since they facilitate their nutrition, increase water absorption, and improve soil structure. Although the AMF association is already known in some species of Myrciaria, no report is available on its association in M. dubia. This study presents, for the first time, the symbiotic association between AMF and M. dubia from the INIA San Roque experimental station located in the Amazon region, Peru. For the morphological and molecular analyses of the AMF, samples of rhizospheric soil and roots from two native accessions of the National Germplasm Bank of M. dubia were collected. Eighteen AMF morphospecies were identified in rhizospheric soil, belonging to nine genera Acaulospora, Ambispora, Entrophospora, Diversispora, Gigaspora, Glomus, Paraglomus, Funneliformis, and Sclerocystis, being the first one the most frequent. The roots of M. dubia showed high colonization by AMF (mean = 91%), and characteristic structures of arbuscular mycorrhizae, such as vesicles, hyphae, and arbuscules, could be observed. Likewise, the molecular analysis detected the presence of genetic material (rDNA) corresponding to AMF in the roots of both accessions. Our results evidenced the symbiotic association between AMF and M. dubia, which encourages further investigation of the functional potential of these microorganisms in this economically crucial agricultural plant in Peru.

Context Coastal wetlands are ecotones interspaced by land and ocean and are among the most sensitive and vulnerable ecosystems worldwide. They are unique in hydrological, edaphic, atmospheric, and biological characteristics, and play important roles in maintaining the ecological security and ecosystem services of coastal zones. Arbuscular mycorrhizae (AM) are symbiont composed of plant roots and arbuscular mycorrhizal fungi (AMF), which are soil-borne microorganisms widely distributed in various habitats. Many previous studies on mycorrhiza have focused on terrestrial ecosystems while few on wetlands, especially coastal wetlands. Method We systematically reviewed previous relevant studies to explore the formation and functions of AM in coastal wetland ecosystems as well as the environmental factors that affect them. Habitat characteristics, morphological types, and species diversity of AMF in the coastal wetlands were summarized. Both responses of AMF to environmental factors during AM formation and the functions of AM in coastal wetlands were discussed. Result AMF are worldwide distributed in coastal wetland and are mainly limited by flooding, hypoxia, soil pH, salinity and the host plants identification. AMF play important roles in coastal wetlands, involving promoting nutrient uptake of host plants, improving the characteristics of rhizospheric soil, and enhancing plant resistance to salt and flooding stress. Conclusion More comprehensive studies of AMF in vitro in coastal wetlands would be helpful for the conservation and restoration of coastal wetland ecosystems in the changing world.
