Molecular Detection of Potato Leaf Roll Polerovirus through Reverse Transcription Polymerase Chain Reaction in Dormant Potato Tubers
A Reverse Transcription-Polymerase Chain Reaction (RT-PCR) technique was applied for the detection of Potato leaf roll polerovirus (PLRV) in dormant potato tubers. A primer pair was designed from the coat protein-encoding fragment of the PLRV genome that amplified a 336-bp product. The amplified product was detected in nucleic acid preparations from leaves and tubers of 5 cultivars and from pur...
متن کاملPD Trafficking of Potato Leaf Roll Virus Movement Protein in Arabidopsis Depends on Site-specific Protein Phosphorylation
Many plant viruses encode for specialized movement proteins (MP) to facilitate passage of viral material to and through plasmodesmata (PD). To analyze intracellular trafficking of potato leaf roll virus (PLRV) movement protein (MP17) we performed GFP fusion experiments with distinct deletion variants of MP17. These studies revealed that the C-terminus of MP17 is essential but not sufficient for...
متن کاملSweet potato leaf curl virus: Efficiency of acquisition, retention and transmission by Bemisia tabaci (Hemiptera: Aleyrodidae)
The sweetpotato whitefly, Bemisia tabaci (Gennadius), vectors numerous plant viruses, including Sweet potato leaf curl virus (SPLCV), a begomovirus. Experiments were conducted on seedlings of an indicator plant, the Brazilian morningglory (Ipomoea setosa Ker Gawl.), and sweet potato [Ipomoea batatas (L.) Lam.] to assess acquisition, retention and transmission of SPLCV by B. tabaci. Assays were ...
متن کاملLeaf Roll-Up and Aquaplaning in Strong Winds and Floods
The submitted fluid dynamics video (see larger and smaller sized versions) shows roll-up and aquaplaning in tree and vine leaves in both strong winds and water flows. The specific goal of this work is to determine how leaves roll up into drag reducing shapes during storms and aquaplane above the water surface during floods. In addition to gaining insight into mechanical adaptation in the natura...
متن کاملSensitivity analysis of leaf wetness duration within a potato canopy
A description and analysis is given of a wetness duration experiment, carried out in a potato field in the centre of the Netherlands in September 2005. The observations are used to design and evaluate a within-canopy dew model which provides the leaf wetness distribution within the canopy caused by dew processes and by precipitation. This withincanopy dew model consists of three layers (bottom,...
