Arbuscular Mycorrhizal Fungi Colonise the Nodules of Phosphite‐Treated Agathis australis

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Agathis australis (kauri), the only member of the ancient conifer family Araucariaceae in New Zealand, is colonised by arbuscular mycorrhizal (AM) fungi. The survival of A. australis is threatened by an Oomycota, Phytophthora agathidicida, the causal agent of kauri dieback. Phosphite injections into the trunk are the primary treatment for kauri dieback

Anthoxanthum odoratum (Poaceae) as a bioindicator of arbuscular mycorrhizal fungi abundance prior to native revegetation on agricultural soils

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 5, Page 2213-2223, December 2025.
ABSTRACT Mycorrhizal fungi, which form symbiotic associations with plant roots, can be critical to the successful establishment of plants. Up to 90% of land plant species form associations with arbuscular mycorrhizal fungi (AMF), which develop fungal structures inside host roots.
