MykorrhizaPfla... is a term used in plant science to describe a particular mycorrhizal association involving plum trees and arbuscular mycorrhizal fungi. It is not a recognized species but a functional description of the symbiosis between Prunus species and members of Glomeromycota. The name reflects a focus on the plant partner (plums) and the mycorrhizal lifestyle, rather than on formal taxonomy.

In this association, intraradical hyphae colonize root cortical cells and form arbuscules, facilitating bidirectional nutrient exchange. Extraradical hyphae extend into the soil to explore nutrients and water, improving phosphorus acquisition and overall root health. Vesicles may be developed as storage structures within the roots. The fungus receives plant-derived carbohydrates in return for improved nutrient uptake, soil exploration, and signaling benefits. The interaction commonly enhances drought tolerance and can influence shoot growth and fruit yield.

Ecology and distribution: MykorrhizaPfla... is reported in temperate plum orchards and other Prunus settings, particularly in soils with limited available phosphorus. Its occurrence is influenced by soil pH, moisture, organic matter, and the compatibility between plum cultivars and local arbuscular mycorrhizal fungal communities. Establishment is typically dependent on agricultural practices that preserve native AMF communities and, in some cases, on inoculation with compatible fungal partners.

Applications and management: Research explores using AMF inoculants to promote this mycorrhizal association as part of sustainable orchard management. Potential benefits include reduced inorganic fertilizer needs, improved nutrient use efficiency, and enhanced resilience to drought. Outcomes are variable and depend on host cultivar, fungal partner, soil conditions, and cultural practices. Economic feasibility and ecological considerations guide adoption.

Taxonomic status: The term remains a descriptive, functional concept rather than a formal taxonomic designation and is not universally adopted in official nomenclature. It serves as a working label in discussions of plum-associated mycorrhizal interactions.
