Correlation between AMF infection and water depth in Thalia dealbata rhizomes.

Historically, it was believed that aquatic plants lacked Arbuscular Mycorrhizal Fungi (AMF). However, Thalia dealbata Fraser ex Roscoe grows in ponds up to over 1 m in depth, and typically relies on AMF infection. To investigate if there is a correlation between AMF infection, water depth, and implied oxygen availability, the volume of air chambers in rhizomes of infected populations of T. dealbata were measured. In shallow water, infection was about 71%, with smaller air chambers. In deeper waters, infection was nearly 32%, with significantly larger air chambers. These data demonstrate that AMF can survive in these depths, and the rhizome response to anoxia may indirectly provide enough air to enable AMF survival.
