M. P. da Silva, G. L. Tylka & G. P. Munkvold, Department of Plant Pathology and Microbiology, Iowa State University, United States
Researchers at the Iowa State University studied the interaction between Rhizoctonia solani and corn lesion nematodes as well as their control with combinations of fungicide and nematicide seed treatments.

How the interaction of a nematode and a fungus results in severe damage to soybean
Dr. A. Westphal, Julius-Kuehn-Institute, Germany
Dr. L. Xing, United States
For years a disease complex of a plant-parasitic nematode and fungal pathogen has damaged soybean fields in the Midwest of the USA. Recently Dr. Andreas Westphal of the Julius-Kuehn-Institute (JKI) and his American collaborator Dr. Lijuan Xing provided mathematical evidence for the synergistic nature of the interaction of Heterodera glycines and Fusarium virguliforme (Xing and Westphal, 2013, JPDP 120:209-217). Crop rotation offers no remedy against the teamed up pathogens. Now, the international author group quantified the specific role of the two pathogens in disease severity.

Fungal community in roots, rhizophere and bulk soil for healthy and diseased pea plants
Articles by the group of Dr. S. Ravnskov, Aarhus University, Denmark
This paper by L. Yu, M. Nicolaisen and Dr. S. Ravnskov from Aarhus University in collaboration with J. Larsen from the Universidad Nacional Autónoma de México shows how the root fungal community changes through the plant growth cycle. Model plant for this was Pisum sativum. It is the first to reveal the whole fungal community in roots and soil.

L. Yu, M. Nicolaisen, J. Larsen & S. Ravnskov
Another study by the same group revealed clear differences in composition of root-associated fungi and the plants health status. They found that AM fungi can be used as soil health indicators.
