摘要： Various members of the viral genera Furovirus and Bymovirus are damaging pathogens of a range of crop species. Infection of the soil-borne plasmodiophorid Polymyxa graminis transmits both Japanese soil-borne wheat mosaic virus (JSBWMV) and the barley yellow mosaic virus (BaYMV) to barley, but their interaction during an episode of their co-infection has not been characterized to date. Here, we present an analysis of the titer of JSBWMV and BaYMV in plants of winter barley growing over a five-month period from late fall until mid-spring. Although JSBWMV was detectable in the plants' roots four weeks earlier than BaYMV, the translocation of both viruses from the root to the leaves occurred nearly simultaneously. Both viruses were co-localized in the roots, leaf sheathes, and leaf blades; however, in some stripes of leaf veins where infection by JSBWMV was prominent, BaYMV was not detectable. A substantial titer of both viruses persisted until early spring, after which JSBWMV became more prominent, being in a range of 10 to 100 times abundant of BaYMV. However, JSBWMV was only able to infect a single wheat accession (cv. Norin 61), whereas all of the wheat entries assayed appeared to be immune to BaYMV infection. Overall, our findings highlight the importance of resistance mechanisms against soil-borne viruses in cereal crops, expanding our understanding of plant-virus interactions and potentially informing strategies for crop protection against viral pathogens.
