About the Researcher and her Research

Since 2001 Ingrid Kottke ( Curriculum) and her group are investigating structural and molecular diversity of mycorrhizas of trees, ericads, and orchids in the tropics. Her interdisciplinary, ecological research projects are situated in the tropical forests of Southern Ecuador and Ethiopia ( places).

How our research foci arose

Our research on mycorrhizas started in 1978 when mycorrhiza research was established in Tübingen - and re-established in Germany after many years of neglect - during the so called “Schönbuch-Project” (Ecological research project in the Schönbuch Nature Park, DFG, ed. G. Einsele, 1986).

Although the obligate, mutualistic fungus-root interaction was realized and named in an ingenious publication by B. Frank in 1885, general acceptance and knowledge was low until the 1970s.

Research impact

Our basic scientific findings on ectomycorrhizal structures and development are now standard knowledge in lecture books, and we still consider structural understanding as fundamental for functional explications of the complex mutualistic interactions – thus this work is not “merely descriptive”.

Research Funding

Funding came from DFG (German Research Foundation), State of Baden-Württmeberg (PEF), BMBF (German Federal Ministry of Education and Research), EU (European Union) and others.

Scope of the Website

The summarized results presented on this website were obtained by the mycorrhiza research group guided by Ingrid Kottke from 1978 until 2007 at the Institute of Systematic Botany, Mycology and Botanical Garden, Eberhard-Karls-University Tübingen ( places).


Ingrid Kottke, née Fiala, studied geology, biology, chemistry and geography at Universities Braunschweig, Bonn and Tübingen, and received her doctoral degree at Eberhard-Karls-University Tübingen in 1968. She than spend three years as teacher at high school and took a sabtical to raise her three children. She came back to University Tübingen in 1978 starting the mycorrhizal research and establishing a research group.

She took habilitation in 1991 and was awarded apl. Prof. in 1999. 15 dissertations were superwised by her. She retired from teaching in April 2004, but still continues with research.
