“…temperata and P. graminis f. sp. tepida were found in G€ odnitz (Ziegler et al 2015). In practical breeding, given the aforementioned difficulties of phenotyping for resistance against the soil-borne viruses, MAS has the potential to be more effective than phenotypic selection.…”

Rye production in European growing areas is constrained by the soilborne cereal mosaic virus (SBCMV) and the wheat spindle streak mosaic virus (WSSMV). To date, no European rye cultivars are known to exhibit resistance against these viruses. In this study, we pursued a quantitative trait locus (QTL) mapping strategy to identify genomic regions for resistance to SBCMV and WSSMV in rye. Three populations, each comprising 100 lines segregating for resistance to SBCMV and/or WSSMV, were evaluated for disease response at two years in three locations in Germany where soils are naturally infested with SBCMV and WSSMV. In the combined analysis across environments, one QTL for SBCMV resistance on chromosome 5R explained 31.9% of the phenotypic variation in one of the populations. For WSSMV resistance, one QTL explaining up to 64.0% of the phenotypic variation was detected on chromosome 7R in each of the three populations. On the Triticeae homoeologous group 5, we found evidence for synteny of the major QTL for SBCMV resistance between the wheat and rye genomes.

“…In addition to durum wheat, SBCMV was reported on common wheat ( Triticum aestivum L.), as well as on the less cultivated rye and the hybrid cereal triticale [ 3 ]. Information about the actual spread of this virus is still limited, but recently it gained increased interest in Europe due to yield losses of up to 70% in infected wheat fields [ 9 , 10 , 11 , 12 ]. The symptoms of the virus are visible in late winter or early spring and then tend to disappear as temperatures rise.…”

Soil-borne cereal mosaic virus (SBCMV) is a furovirus with rigid rod-shaped particles containing an ssRNA genome, transmitted by Polymyxa graminis Led., a plasmodiophorid that can persist in soil for up to 20 years. SBCMV was reported on common and durum wheat and it can cause yield losses of up to 70%. Detection protocols currently available are costly and time-consuming (real-time PCR) or have limited sensitivity (ELISA). To facilitate an efficient investigation of the real dispersal of SBCMV, it is necessary to develop a new detection tool with the following characteristics: no extraction steps, very fast results, and high sensitivity to allow pooling of a large number of samples. In the present work, we have developed a reverse transcription loop-mediated isothermal amplification (RT-LAMP) protocol with such characteristics, and we have compared it with real-time PCR. Our results show that the sensitivity of LAMP and real-time PCR on cDNA and RT-LAMP on crude extracts are comparable, with the obvious advantage that RT-LAMP produces results in minutes rather than hours. This paves the way for extensive field surveys, leading to a better knowledge of the impact of this virus on wheat health and yield.
