Abstract

leaves infected with each isolate was mechanical inoculated onto leaves of coriander plants (30-35 d old). Newly emerged leaves developed epinasty, crumpling and light green mottling by 14 dpi, and WMV infection was confirmed by RT-PCR with the WMV-specific primer pair WMV-UNI-1F and WMV-UNI-1R (Kim et al. 2019). Thus, Koch's postulates were fulfilled for this leaf mottling disease of coriander. Furthermore, the isolates from coriander induced stunting and distortion and mosaic in leaves of melon, pumpkin and squash plants by 7 dpi, whereas watermelon plants developed stunting and small leaves with mild mottling by 20 dpi. Similar results were obtained with sap prepared from infected coriander leaves. Thus, infected coriander plants are a potential inoculum source for cucurbits via several aphid vectors (Keinath et al. 2017). This is the first report of a mottle disease of coriander caused by WMV, and adds to the wide host range of the virus.
