Molecular Characterization of Watermelon Chlorotic Stunt Virus (WmCSV) from Palestine
The incidence of watermelon chlorotic stunt disease and molecular characterization of the Palestinian isolate of Watermelon chlorotic stunt virus (WmCSV-[PAL]) are described in this study. Symptomatic leaf samples obtained from watermelon Citrullus lanatus (Thunb.), and cucumber (Cucumis sativus L.) plants were tested for WmCSV-[PAL] infection by polymerase chain reaction (PCR) and Rolling Circ...
متن کاملComplete Nucleotide Sequence of Watermelon Chlorotic Stunt Virus Originating from Oman
Watermelon chlorotic stunt virus (WmCSV) is a bipartite begomovirus (genus Begomovirus, family Geminiviridae) that causes economic losses to cucurbits, particularly watermelon, across the Middle East and North Africa. Recently squash (Cucurbita moschata) grown in an experimental field in Oman was found to display symptoms such as leaf curling, yellowing and stunting, typical of a begomovirus in...
متن کاملTropane alkaloids of Datura innoxia from Morocco.
Fifty three alkaloids were identified in the organs (roots, stems, leaves, flowers, and seeds) of Datura innoxia by GC/MS. Seventeen of them are reported for the first time for this species and one nor-derivative, 3-phenylacetoxynortropane (28), for the genus Datura. Furthermore, four new tropane esters were tentatively identified as 3-acetoxy-6,7-epoxytropane (acetylscopine) (10), 3-acetoxy-6-...
متن کاملQuantification and Localization of Watermelon Chlorotic Stunt Virus and Tomato Yellow Leaf Curl Virus (Geminiviridae) in Populations of Bemisia tabaci (Hemiptera, Aleyrodidae) with Differential Virus Transmission Characteristics
Bemisia tabaci (Gennadius) is one of the economically most damaging insects to crops in tropical and subtropical regions. Severe damage is caused by feeding and more seriously by transmitting viruses. Those of the genus begomovirus (Geminiviridae) cause the most significant crop diseases and are transmitted by B. tabaci in a persistent circulative mode, a process which is largely unknown. To an...
