Frequent migration of introduced cucurbit-infecting begomoviruses among Middle Eastern countries.
Virol. J.
PUBLISHED: 06-13-2014
Show Abstract
Hide Abstract
In the early 2000s, two cucurbit-infecting begomoviruses were introduced into the eastern Mediterranean basin: the Old World Squash leaf curl virus (SLCV) and the New World Watermelon chlorotic stunt virus (WmCSV). These viruses have been emerging in parallel over the last decade in Egypt, Israel, Jordan, Lebanon and Palestine.

HPLC-DAD-ESI-MS/MS screening of bioactive components from Rhus coriaria L. (Sumac) fruits.
Food Chem
PUBLISHED: 03-25-2014
Show Abstract
Hide Abstract
Rhus coriaria L. (sumac) is an important crop widely used in the Mediterranean basin as a food spice, and also in folk medicine, due to its health-promoting properties. Phytochemicals present in plant foods are in part responsible for these consequent health benefits. Nevertheless, detailed information on these bioactive compounds is still scarce. Therefore, the present work was aimed at investigating the phytochemical components of sumac fruit epicarp using HPLC-DAD-ESI-MS/MS in two different ionisation modes. The proposed method provided tentative identification of 211 phenolic and other phyto-constituents, most of which have not been described so far in R. coriaria fruits. More than 180 phytochemicals (tannins, (iso)flavonoids, terpenoids, etc.) are reported herein in sumac fruits for the first time. The obtained results highlight the importance of R. coriaria as a promising source of functional ingredients, and boost its potential use in the food and nutraceutical industries.

Molecular characterization of watermelon chlorotic stunt virus (WmCSV) from Palestine.

Hide Abstract
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 Circle Amplification (RCA). Disease incidence ranged between 25%-98% in watermelon fields in the studied area, 77% of leaf samples collected from Jenin were found to be mixed infected with WmCSV-[PAL] and SLCV. The full-length DNA-A and DNA-B genomes of WmCSV-[PAL] were amplified and sequenced, and the sequences were deposited in the GenBank. Sequence analysis of virus genomes showed that DNA-A and DNA-B had 97.6%-99.42% and 93.16%-98.26% nucleotide identity with other virus isolates in the region, respectively. Sequence analysis also revealed that the Palestinian isolate of WmCSV shared the highest nucleotide identity with an isolate from Israel suggesting that the virus was introduced to Palestine from Israel.

The helper component-proteinase of the Zucchini yellow mosaic virus inhibits the Hua Enhancer 1 methyltransferase activity in vitro.
J. Gen. Virol.
PUBLISHED: 05-18-2011
Show Abstract
Hide Abstract
The helper component-proteinase (HC-Pro) is a multifunctional protein found among potyviruses. With respect to its silencing suppressor function, small RNA binding appears to be the major activity of HC-Pro. HC-Pro could also exhibit other suppressor activities. HC-Pro may inhibit the Hua Enhancer 1 (HEN1) activity. There is indirect evidence showing that either transient or stable expression of HC-Pro in plants results in an increase of non-methylated small RNAs. Here, we demonstrated that recombinant Zucchini yellow mosaic virus (ZYMV) HC-Pro inhibited the methyltransferase activity of HEN1 in vitro. Moreover, we found that the HC-Pro(FINK) mutant, which has lost small RNA-binding activity, inhibited HEN1 activity, while the truncated proteins and total soluble bacterial proteins did not. Using the ELISA-binding assay, we provided evidence that the HC-Pro(FRNK) wild-type and HC-Pro(FINK) both bound to HEN1, with HC-Pro(FRNK) binding stronger than HC-Pro(FINK). Motif mapping analysis revealed that the amino acids located between positions 139 and 320 of ZYMV HC-Pro were associated with HEN1 interaction.

Expression, purification and functional characterization of recombinant Zucchini yellow mosaic virus HC-Pro.
Protein Expr. Purif.
PUBLISHED: 06-07-2010
Show Abstract
Hide Abstract
HC-Pro is a helper component-proteinase which acts as a multifunctional protein in the potyviral life cycle. Apart from its proteolytic activity, HC-Pro has the capacity to bind duplex small RNAs (sRNAs). To investigate HC-Pro-mediated sRNA binding in vitro, high amounts of purified protein are required. For this purpose, the Zucchini yellow mosaic virus (ZYMV) HC-Pro was expressed as a fusion with hexa-histidine (6xHis) or maltose-binding protein (MBP) in Escherichia coli. The expressed fusion proteins were purified by affinity chromatography. 6xHis:HC-Pro and MBP:HC-Pro were partially soluble. Electrophoretic mobility-shift assays demonstrated that only MBP:HC-Pro exhibits the sRNA binding activity. The recombinant HC-Pro bound 21 bp siRNAs as well as 19 bp and 24 bp siRNAs. A point mutation in the highly conserved FRNK box produced the HC-Pro(FINK) protein, previously shown to be associated with reduced viral symptoms and weak sRNA binding. In this study, sRNA binding of the MBP:HA-HC-Pro(FINK) was not detectable. The high yield of purified HC-Pro offers the possibility to study the biochemistry of the protein in detail.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
