Cucurbit chlorotic yellows virus (CCYV) and cucurbit yellow stunting disorder (CYSDV) are two closely related criniviruses that often coinfect cucurbits associated with disease. Both viruses distributed worldwide transmitted in a semipersistent manner by the whitefly vectors Bemisia tabaci MED or MEAM1. The major goal of this study was to provide insight into interaction CCYV CYSDV cucumber eff...
