      abstract     = {Brachypodium distachyon (L.) P.Beauv. (Bd) has previously
                      been developed as a pathosystem model for the wheat root rot
                      pathogen Rhizoctonia solani Kühn anastomosis group 8 (AG8).
                      Here we explore variation in resistance to R. solani AG8 in
                      Bd, to determine whether genomic tools could be used to find
                      Bd genes involved in the grass defence response, with the
                      aim of using this information for the improvement of
                      Rhizoctonia root rot resistance in wheat. We looked for
                      variation in resistance to R. solani AG8 in a diverse Bd
                      natural accession collection and in Bd T-DNA insertion lines
                      selected based on putative mechanisms reported for tagged
                      genes. All lines were susceptible to the pathogen.
                      Repeatable and significant variation in resistance was
                      measured in both groups, with greater variation in
                      resistance found across the natural accessions than in the
                      T-DNA lines. The widest and most repeatable variation in
                      resistance was between lines Koz-3 and BdTR 13a. The ratio
                      of R. solani AG8-inoculated to uninoculated root length for
                      line Koz-3 was $33\%$ greater than the same ratio for line
                      BdTR 13a. The increased resistance of Koz-3 was associated
                      with nodal root initiation in response to the pathogen. A
                      negative correlation between seedling vigour and resistance
                      was observed, but found not to be the sole source of
                      variation in resistance to R. solani AG8. The only T-DNA
                      line with significantly greater resistance to R. solani AG8
                      than the reference line had an insertion in a putative
                      galactosyltransferase gene; however, this result needs
                      further confirmation. Genetic resistance to Rhizoctonia root
                      rot is not available in wheat cultivars and only a few
                      instances of quantitative resistance to the pathogen have
                      been described within close relatives of wheat. Brachypodium
                      distachyon offers potential for further investigation to
                      find genes associated with quantitative resistance and
                      mechanisms of tolerance to R. solani AG8.},
