Analyses of the microbiome for identification and selection of potential antagonists and their evaluation in planta against the causative agent of ash dieback

Analyses of the microbiome for identification and selection of potential antagonists and their evaluation in planta against the causative agent of ash dieback

Background and Objective

Ash dieback caused by Hymenoscyphus fraxineus has spread since middle of the nineties across Europe and threatens to destroy ash forests. The biological control of this disease by microbial antagonists, which directly attack and/or suppress the pathogen by competition, represents a promising possibility to inhibit ash dieback. The use of suitable microorganisms may provide synergistic effects in combination with the selection of resistant plant clones. The project aims to develop a biological control system on the basis of epi-and endophytic isolates, which are able to persist in ash plants. Promising bacteria and fungi are selected based on the comparison of the microbiomes of infected and resistant plants applying next generation sequencing. The selected microbial isolates will be genetically characterized and evaluated with regard to their antagonistic potential. Finally, antagonistic isolates and/or microbial consortia will be evaluated in planta. This promising approach offers the chance of applying antagonistic microorganisms for the control of ash dieback in seed orchards and forests.
