Courgette (Cucurbita pepo) is one of the main cucurbit crops grown in Iraq for local consumption. Viruses are a major threat to production Iraq, particularly whitefly-transmitted viruses (Mohammed et al., 2021). In 2022 growing season, courgette plants with extensive leaf vein-yellowing symptoms (Figure 1), associated whitefly infestation, were observed fields around Al-Yusufiyah, Baghdad Provi...

Papaya ringspot, caused by papaya ringspot virus, is the most important disease of the crop in Florida, severely limiting the potential for commercial production. Sometimes this virus infects cucurbits. Earliest symptoms in papaya appear as yellowing and vein-clearing of younger leaves. A prominent yellow mottling of the leaves follows. One or more lobes of infected leaves may become severely d...

In Bangladesh, citrus is an important fruit crop that becoming more commonly cultivated in commercial plantations. March 2019, we observed yellowing, vein clearing, and mild mosaic symptoms citron (Citrus medica). Based on systematic serological molecular analyses of the symptomatic leaf samples, Citrus tristeza virus (CTV) was identified. To best our knowledge, this first report CTV any Bangla...

Tomato yellow leaf curl China virus (TYLCCNV) is a monopartite begomovirus associated with different betasatellites. In this study, we investigate two different isolates of Tomato yellow leaf curl China betasatellite (TYLCCNB) to determine what features of the viral genome are required for induction of characteristic phenotypic differences between closely-related betasatellite. When co-agroinoc...

ABSTRACT A novel whitefly-transmitted member of the family Potyviridae was isolated from a squash plant (Cucurbita pepo) with vein yellowing symptoms in Florida. The virus, for which the name Squash vein yellowing virus (SqVYV) is proposed, has flexuous rod-shaped particles of approximately 840 nm in length. The experimental host range was limited to species in the family Cucurbitaceae, with th...
