“…It will be interesting to compare the phylogenetic relationship of T. secalis and T. trabutii to T. controversa on the whole-genome level. Furthermore, T. controversa, unlike the majority of smut fungi that are restricted to a single or few closely related host species 64 , has been reported to infect not only wheat but also other members of the Poaceae family 65 . We examined T. controversa collected from Elymus repens and T. controversa 11 , 66 , 67 (syn.…”

Tilletia controversa causing dwarf bunt of wheat is a quarantine pathogen in several countries. Therefore, its specific detection is of great phytosanitary importance. Genomic regions routinely used for phylogenetic inferences lack suitable polymorphisms for the development of species-specific markers. We therefore compared 21 genomes of six Tilletia species to identify DNA regions that were unique and conserved in all T. controversa isolates and had no or limited homology to other Tilletia species. A loop-mediated isothermal amplification (LAMP) assay for T. controversa was developed based on one of these DNA regions. The specificity of the assay was verified using 223 fungal samples comprising 43 fungal species including 11 Tilletia species, in particular 39 specimens of T. controversa, 92 of T. caries and 40 of T. laevis, respectively. The assay specifically amplified genomic DNA of T. controversa from pure cultures and teliospores. Only Tilletia trabutii generated false positive signals. The detection limit of the LAMP assay was 5 pg of genomic DNA per reaction. A test performance study that included five laboratories in Germany resulted in 100% sensitivity and 97.7% specificity of the assay. Genomic regions, specific to common bunt (Tilletia caries and Tilletia laevis together) are also provided.

“…The current distribution of wheat dwarf bunt, Tilletia controversa, in Eurasia (Gassner & Niemann, 1954;CMI, 1968) and in North America (Young, 1935;Conners, 1954;Baylis, 1958;Purdy et al, 1963;Wallen & Ednie, 1972) revealed that the geographical distribution of this disease was closely related to the climatic conditions of the different wheat cultivation areas of the world (Hardison et al, 1959;Purdy et al, 1963;CMI, 1968). Historically, the northwest Pacific region of North America is an area of high infestation both of Tilletia tritici and T. controversa (Purdy et al, 1963;Hoffmann, 1982;Trione, 1982).…”

The adaptability of Tilletia controversa was studied in particular relation to China, where wheat is cultivated under various climatic conditions. Teliospore germination is closely influenced by temperature, light and soil humidity. Establishment of T. controversa depends on: (1) persistent low temperature (0–10°C) within the surface layer of the soil, in combination with adequate soil moisture; (2) presence of seedlings of susceptible wheat cultivars, especially in the early stage of tillering before or during overwintering. The climatic conditions of various wheat‐growing areas in China were compared with the results obtained in this study, and areas of prevalent damage and of marginal damage were predicted. It was concluded that T. controversa presents a considerable hazard to China if it accidentally enters.
