Genetic evidence for auxin involvement in arbuscular mycorrhiza initiation.

Hanlon MT, Coenen C. Genetic evidence for auxin involvement in arbuscular mycorrhiza initiation. New Phytol. 2010;198:DOI:10.1111/j.1469-8137.2010.03567.x. (Allegheny College)

This study used mutant tomato plants to demonstrate that the plant hormone auxin is required for the establishment of a mutualistic symbiosis between plant roots and mycorrhizal fungi. Fungus-root interactions were characterized in tissue culture and in greenhouse-grown plants. Mycorrhiza formation in mutant roots was disrupted in both systems, indicating that crop breeding efforts that affect root auxin relations may inadvertantly cause disruptions in this agriculturally important symbiosis. Catharina Coenen is an associate professor of biology. Meredith Hanlon performed the experiments described in this study from June 2006 to August 2008 as an undergraduate researcher. She is currently an NSF predoctoral fellow in the Intercollege Graduate Degree program in Plant Biology at The Pennsylvania State University. The work was supported by a USDA SEED grant to CC and grants from the Allegheny362 College Class of '39 Fund and the Harold State Research Fellowship to MTH.
