Mycorrhizal presence in Thalia dealbata roots.

Thalia dealbata Fraser ex Roscoe is a marginally aquatic plant of the family Marantaceae. It is native to the southeastern region of the United States. The plant appears to be an aggressive nitrogen mitigator. However, the role that rhizosphere microorganisms play in this mitigation process has not been determined. Even though Thalia dealbata grows in water depths up to four feet, mycorrhizae could still be present, and play a key role in facilitating nitrogen uptake. Roots and rhizomes from two environmentally different sites were cleared, stained and examined for mycorrhizal associations. Results showed characteristics of a facultative symbiosis with Vesicular Arbuscular Mycorrhizae. Irrespective of environmental factors, colonization was ubiquitous. However, percent colonization appeared to be affected by several environmental factors.
