“…D1 had a privileged interaction with either the carbon source derived from the fungus, which was obtained by the bacterium capable of converting organic P into inorganic P, or the bacterial community that lives on the surface of hyphae, which can be at least partially controlled by the bacterium of the genus Streptomyces. This is done mainly by limiting the activity of bacteria that have low P-mineralizing potential, thus allowing AM fungi to access P [70,71].…”

Arbuscular mycorrhizal fungi (AMF) such as Rhizophagus intraradices (formerly known as Glomus intraradices) are of great importance to maintaining the soil ecosystem while supporting sustainable agriculture and practices. This review explores the taxonomy of Rhizophagus intraradices, their attributes, mycorrhizal symbiosis, plant growth improvement, nutrient recycling in the soil, soil health and environmental rehabilitation, and challenges that impede the effective use of AMF in agriculture. AMF impacts soil structure by releasing organic compounds like glomalin, improving total organic carbon and water-holding capacity, and reducing water scarcity. AMF, in sustainable agriculture, not only improves crop productivity through nutrient uptake but also enhances soil fertility and plants’ resistance to so-called stress from abiotic factors as well. The integration of AMF with other beneficial microorganisms in organic farming will be powerful both to ensure long-term soil output and to protect food from bacteria. Nevertheless, chemical inputs and spatial biases of the researchers remain matters to be solved in connection with the broad feasibility of AMF use.

“…They are also very important for crop production and growth and establishment of perennial plants, particularly woody plants with deep roots. Moreover, they help in a buildup and maintenance of mycorrhizal networks, or hyphal bridge (hyphal linkage) to exchange resources amongst tree species (Muthukumar et al, 2022). AMF also increase the volume of soil to be exploited and thereby improve phosphorous (P) use e ciency and P access to plants and its cycling in the soil (Muleta et al, 2008).…”

In terrestrial ecosystems, arbuscular mycorrhizal fungi (AMF) helps land plants in nutrient uptake and protect them against abiotic and abiotic stresses. It is important to study the AMF-plant relationship to fully realize the bene cial potential to support establishment, growth and maintenance of mycorrhizal plants in different ecosystems. Therefore, the objective of this study was to determine the diversity, abundance and population densities of AMF and quantify root colonization of the indigenous trees in Munessa forest. To this end, composite soil samples and ne roots were collected from seven dominant indigenous trees within 10 m x10 m plots in the forest. AMF spores were extracted for taxonomic identi cation and root colonization with AMF structures was determined for each trees. A total of 39 AMF species (morphotypes) belonging to 10 genera were recovered. Glomus was the most dominant genus followed by Acaulospora. The highest genus richness was recorded from Croton macrostachyus (9). Mean AMF spore density was signi cantly different (p < 0.05) among indigenous trees, ranging from 860 spores/100 g of dry soil under Albizia shimperiana to 2830 spores/100 g of dry soil under Pouteria adol ifriedericii. The highest root hyphal colonization was observed in Millettia ferruginea (71%) and Podocarpus falcatus (64%), respectively. Albizia shimperiana was the least colonized tree (44%). AMF spore density was positively correlated with soil available phosphorus (p < 0.05). Extensive studies are required to select AMF inocula for plant growth promotion and recruitment of tree seedlings for plantation and, restoration of forest vegetation and rehabilitation of degraded and dry lands.

Therefore, the objective of this study was to determine the diversity, abundance and population densities of AMF and quantify root colonization of the indigenous trees in Munessa forest. To this end, composite soil samples and fine roots were collected from seven dominant indigenous trees within 10 m x10 m plots in the forest. AMF spores were extracted for taxonomic identification and root colonization with AMF structures was determined for each trees. A total of 39 AMF species (morphotypes) belonging to 10 genera were recovered. Glomus was the most dominant genus followed by Acaulospora.
