“…Stagonospora blotch has been reported to affect Brachypodium sylvaticum (Halbritter et al, 2012). Additionally, Falter and Voigt (2014) have reported colonization of brachypodium by S. nodorum and the economically important barley-infecting Pyrenophora teres (Liu et al 2011) using a detached leaf assay. Thus, study of the interaction of brachypodium with cereal-infecting Stagonospora and Pyrenophora species may be possible under certain laboratory conditions.…”

Background Cereal diseases cause tens of billions of dollars of losses annually and have devastating humanitarian consequences in the developing world. Increased understanding of the molecular basis of cereal host-pathogen interactions should facilitate development of novel resistance strategies. However, achieving this in most cereals can be challenging due to large and complex genomes, long generation times and large plant size, as well as quarantine and intellectual property issues that may constrain the development and use of community resources. Brachypodium distachyon (brachypodium) with its small, diploid and sequenced genome, short generation time, high transformability and rapidly expanding community resources is emerging as a tractable cereal model.Scope Recent research reviewed here has demonstrated that brachypodium is either susceptible or partially susceptible to many of the major cereal pathogens. Thus, the study of brachypodium-pathogen interactions appears to hold great potential to improve understanding of cereal disease resistance, and to guide approaches to enhance this resistance. This paper reviews brachypodium experimental pathosystems for the study of fungal, bacterial and viral cereal pathogens; the current status of the use of brachypodium for functional analysis of cereal disease resistance; and comparative genomic approaches undertaken using brachypodium to assist characterization of cereal resistance genes. Additionally, it explores future prospects for brachypodium as a model to study cereal-pathogen interactions.Conclusions The study of brachypodium-pathogen interactions appears to be a productive strategy for understanding mechanisms of disease resistance in cereal species. Knowledge obtained from this model interaction has strong potential to be exploited for crop improvement.

“…It appears resistance is controlled by a large number of QTL that vary in effect size, with large effect QTL on 7H. Liu et al (2011) andMcLean et al (2014) summarised that resistance to SFNB was contributed by major effect genes, along with minor effect QTL, with two named genes (i.e. Rpt6 and Rpt4) with large effects located on 5H and 7H (Manninen et al 2006;Williams et al 1999) and one unnamed major gene on 4H (Friesen et al 2006) having been found to explain 64-84 % of the phenotypic variation individually.…”

significant QTL were validated across multiple breeding populations, with 22 conferring resistance at both seedling and adult plant growth stages. The remaining 7 QTL conferred resistance at either seedling (2 QTL) or adult plant (5 QTL) growth stages only. These 29 QTL represented 24 unique genomic regions, of which five were found to co-locate with previously identified QTL for SFNB. The results indicated that SFNB resistance is controlled by a large number of QTL varying in effect size with large effects QTL on chromosome 7H. A large proportion of the QTL acted in the same direction for both seedling and adult responses, suggesting that phenotypic selection for SFNB resistance performed at either growth stage could achieve adequate levels of resistance. However, the accumulation of specific resistance alleles on several chromosomes must be considered in molecular breeding selection strategies.

Seedling reactions of 20 barley cultivars grown in Turkey were determined under greenhouse conditions to six isolates of Drechslera teres f. maculata, the causal agent of spot form of barley net blotch disease. Isolates were obtained from different provinces of Turkey. Differences among the reactions of the cultivars to the isolates of the fungus were observed. Isolate differences in pathogenicity for each cultivar were also present.
