Abstract: This study explores the arbuscular mycorrhizal (AM) fungi associations of Agave tequilana, an emerging crop with significant commercial potential that is increasingly being grown outside its native distribution in the arid regions of the Americas. A greenhouse experiment was conducted using field-collected soil inoculum from various locations in South Australia to inoculate A. tequilana plus Plantago lanceolata as a comparative model host. Metagenomic sequencing of the colonized roots with AM fungal-specific amplicons assessed the AM fungal community structure. The Shannon alpha diversity was similar between both plant species, and both predominantly associated with the genus Glomus. However, A. tequilana had a narrower AM fungal community compared to P. lanceolata, which was associated with a broader diversity of AM fungi. Beta diversity analysis of the AM fungal community composition revealed that the factor species (agave/plantago) was significant (p = 0.0001), whereas the inoculum location was not (p = 0.29). The association of A. tequilana with AM fungi from the family Acaulosporaceae, as found in Mexican studies, could not be confirmed. These findings suggest a specialized adaptation of A. tequilana to specific AM fungal species, which could have important implications for using AM fungi in sustainable agave production when cultivated outside their native regions. Highlights: Agave tequilana associates mainly with the Glomus genus. Agave shows narrower AM fungal beta diversity compared to Plantago lanceolata. AM fungal community structure in Australian-grown agave diverges from patterns observed in Mexican studies. Need for research to support agave cultivation with AM fungi in non-native areas.
