“…Symptoms caused by CWMV are light chlorotic streaking on young leaves but bright yellow chlorotic streaking or even purple chlorotic stripes on older leaves. At the later stages of infection, the intermittent chlorosis on leaves can gradually develop into chlorotic stripes and the plants become stunted, wilt and later die (Guo et al 2019) (Fig. 1b).…”

In China, soil-borne viruses transmitted by the root parasite Polymyxa graminis have caused significant yield loss in winter wheat for many years. At present, it is believed that two main soil-borne RNA viruses, namely wheat yellow mosaic virus (WYMV) and Chinese wheat mosaic virus (CWMV) are responsible for such losses. The molecular characteristics and infection processes of these two viruses have been intensively investigated and described substantially in detail, following the complete sequencing of their respective genomes. In this review, we highlight our recent findings on the distribution of WYMV and CWMV in China, the associated crop damage, the biological functions of WYMV and CWMV proteins as well as the viral temperature sensitivities. We also describe the characteristics of the resistance genes and discuss the novel virus–plant arms race strategies in hope of enlarging our understanding on the theme of virus-plant interactions. Finally, we compare current disease-management options and suggest the application of biotechnology-based genetic resistance to develop more cost-effective countermeasures for controlling soil-borne virus diseases in the future.

“…China is the world's largest wheat producers and has been challenged with viral diseases for a long time. For examples, wheat yellow mosaic disease caused by both Wheat yellow mosaic virus (WYMV) and Chinese wheat mosaic virus (CWMV) has severely damaged the wheat production in China [5][6][7].…”

In this work, we report the detection of a novel single strand RNA virus from wheat tentatively named as Triticum aestivum-associated virga-like virus 1 (TaAVLV1). Further characterization revealed that the complete genome of TaAVLV1 can be divided into two segments, RNA1 and RNA2. Each fragment excluding their respective polyA tails has 3530 and 3466 nt in length and contains only one open reading frame (ORF). The ORF in RNA1 encodes an RNA-dependent RNA polymerase (RdRp), while the other in RNA2 encodes a putative protein carrying MET and HEL domains. Phylogenetic analysis showed that the RdRp of TaAVLV1 was closely related to the RdRp protein members of the unclassi ed virga-like virus group in the family Virgaviridae. Therefore, we have identi ed TaAVLV1 as a putative novel virga-like virus belonging to the family Virgaviridae.

In this work, we report the detection of a novel single strand RNA virus from wheat，tentatively named Triticum aestivum-associated virga-like virus 1 (TaAVLV1). Further characterization revealed that the complete genome of TaAVLV1 was divided into two segments, RNA1 and RNA2, which were 3530 and 3466 nt long, excluding the polyA tail. These segments contained two open reading frames (ORFs). The ORF in RNA1 encoded an RNA-dependent RNA polymerase (RdRp), while the ORF in RNA2 encoded a putative protein carrying MET and HEL domains. Phylogenetic analysis based on the RdRp protein of each representative genus of Virgaviridae placed TaAVLV1 in an unclassified virga-like virus clade the family. To our knowledge, this is the novel virga-like virus detected from wheat. Future studies will be conducted to examine its effect on host growth and development.
