News and events

We successfully launched our first SYMPLANTA® product-line of research-grade AM fungi in December 2011. Many of the AM fungi offered have also been tested in field experiments and commercial applications. Since May 2012, a separate product-line was serving agricultural applications and end-consumers. Since November 2013 these agricultural and other end-consumer (non-research) products are marketed through partners.


From 2013 - 2017, there was a number of media responses to our work, including radio broadcast, science TV, article in Greenpeace magazine, etc. - see, e.g., our facebook page

Since 2013 we have licenced know how to the Wilhelms GmbH ( You may find news about numerous prices, awards, etc. for the products developed, at:

Press release LMU Munich about the publication 'Schoch et al. (2012)' in PNAS (see reference at the right), (in German German) Ein biologischer Barcode
: Wie unsichtbare Pilze ein Gesicht bekommen ('A biological barcode: how invisible fungi acquire a face'):

Anders als Fliegenpilz und Co., haben die arbuskulären Mykorrhiza mit auffälligen Fruchtkörpern nicht viel am Hut. Ein „DNA-Barcode“ lässt diese kaum zu unterscheidenden, aber wirtschaftlich wichtigen Pilze nun eindeutig Farbe bekennen.
Viele Getreidepflanzen, Sträucher und auch Bäume haben eines gemein: Sie sind auf die Symbiose mit arbuskulären Mykorrhizapilzen angewiesen. Ein internationales Forscherteam hat nun ein molekulares Nachweissystem - einen "DNA-Barcode" als genetische Erkennungssequenz - definiert, um ansonsten oft kaum unterscheidbare Pilzarten eindeutig identifizieren zu können. "Dies erlaubt eine genaue Analyse der Pilze, auch für mögliche Anwendungen", sagt LMU-Biologe und Projektpartner Professor Arthur Schüßler.
Die Gruppe an der LMU bearbeitet die arbuskulären Mykorrhizapilze, auch Glomeromycota genannt. Diese leben an und in den Wurzeln von Landpflanzen, denen sie Nährstoffe zuführen, um dafür energiereiche Kohlenhydrate zu erhalten. "Für die hoch diverse Gruppe der Pilze haben bislang DNA-Barcodes gefehlt, die bei Pflanzen und Tieren bereits definiert waren", sagt Schüßler. "Nun aber können auch die vielen 'unsichtbaren' Pilzarten direkt im Boden oder in Pflanzenwurzeln nachgewiesen und auch Gemeinschaften aus Symbionten untersucht werden – auch um etwa den Ertrag wichtiger Nutzpflanzen zu steigern."(suwe)

January 2018
Symplanta moved to Darmstadt, where our academic research on AM fungi once started!

July 2017
We again offer deep sequencing (MiSeq) based monitoring of AM fungi from roots or soil, based on 450 bp amplicon sequencing

December 2016
Our partner, Wilhelms GmbH, in 2016 has sold AM fungi based microbial inocula for ca. 4000 ha, mainly for corn and potato.

January 2016
Our methods for AM fungi detection and characterisation are publishes in a methodology book series. See publication Senés-Guerrero and Schüßler 2016.

October 2015
Publication submitted about:

Durum wheat quality highly improved by AM fungal inoculation.

August 2015
Surprisingly limited AMF community diversity detected by 454 sequencing in soybean fields in Italy.
Yet unpublished.

August 2014, 2015
Conserved AMF core-communities detected in potato from different geographic locations in South America. See publications Senés-Guerrero et al. 2014, Senés-Guerrero and Schüßler 2015.

July 2014
SYMPLANTA has limited its portfolio of AM fungal inocula for research, as most demand is for one fungus only. We now focus on this, and provide other specific products only on specific demand.

March 2014
Agricultural inoculum for 4500 ha sold by Wilhelms GmbH, marketing agricultural and other end-consumer inoculum.

January 2014
Problems with filling demands (currently sold-out) lead us to the decition to further change production, thus only little inoculum was sold until July/August 2014.

November 2013
SYMPLANTA contracted with Wilhelms GmbH to become share-holder and develop and market agricultural products in larger scales. Agricultural products and applications are now developed in this newly founded company. Do not hesitate to cuntact us for such products and applications. See

July 2013
Result of field-experiment with lettuce:
21% and 12% freshweight increase
by inoculation with AMF. Two weeks after an early harvest at 17. June (which is mentioned in the last 'news', below), a clear positive response of both lettuce varieties was found. Although the weather was 'normal' (heavy precipitation and cold temperatures before) only during last 2 weeks, there was a clear difference in FW. The graph also demonstrates, that +AMF plants can be harvested 1 week earlier than -AMF plants, to obtain the same FW.

June 2013
Lettuce-trials revealed up to 42% higher freshweigth after mycorrhizal fungi inoculation for one, but insignificant 3% for another viariety - under identical field conditions - demonstrating how different plant responses can be. The photograph shows comparison of the responding plants approx. 4 weeks before harvest.

March-May 2013
Field trials with different crops (mainly maize) setup as pilot projects together with our partners, with more than 20 conventional as well as organic production farmers.
Later remark: Unfortunately many of the maize trials in 2013 were not analysed, because the extremely cold and wet weather in spring. Some of the maize in Bavaria was not even harvested, due to these
climatic conditions. AMF application could not make much difference under such wet and cold conditions (which were opposite to the usual situation, which is that springs get dryer and warmer). Yield increase was only analysed from one trial, being 4-5%.

February 2013
