Using naturally occurring endophytic fungi or bacteria associated with wheat as a biological control agent against the cereal cyst nematodes, Heterodera species - Follow up project to EP 2228: stipend to publish the resuls
Project
Project code: JKI-EP-08-2304
Contract period: 01.01.2017

Purpose of research: Inventory & Assessment
Keywords: crop protection, biological control, cereal cyst nematode, Heterodera spp.
Cereal cyst nematodes (Heterodera spp./CCN) are causing significant losses in wheat, especially in arid regions of the world. In 2012 fungal hyphae associated with nematode cysts were found in trial fields of CIMMYT in Turkey. These findings were correlated with strongly reduced nematode cyst numbers after harvest. The main aim of the initially GIZ-funded cooperation project with CIMMYT Turkey was therefore to isolate endophytes of wheat plants of this site, to characterise the isolates using molecular systematic methods and to test their antagonistic effects on the nematodes. During the course of the project over100 fungal and 60 bacterial strains were isolated. Six fungal species proved to be new to science. All of these species showed parasitic interactions with the cysts and eggs of CCN. In addition to fungal isolation secondary compounds of the fungi were isolated in collaboration with the Helmholtz Institute for Infection Biology. So far, two of the isolated compounds showed potential for nematode control. One of the isolated compounds proved to be completely new after structural elucidation. All these findings will be published in peer-reviewed journals facilitated by the stipend.
