Abstract

Tomato zonate spot virus (TZSV), a new species of genus Tospovirus, caused significant losses in yield and problems in quality of many important vegetables and ornamentals in Southwest China and posed a serious threat to important economic crops for the local farmers. A convenient and reliable method was urgently needed for rapid detection and surveillance of TZSV. The nucleocapsid protein (N) of TZSV was expressed in Escherichia coli and purified, and was used as the antigen to immunize BALB/c mice. Three monoclonal antibodies (mAbs) 3A2, 5D2 and 5F7 against TZSV were obtained through the hybridoma technique. The mAb 3A2 was conjugated with colloid gold as detecting reagent; mAb 5D2 was coated on a porous nitrocellulose membrane as the detection line and protein A was coated as the control line respectively. The colloid gold immunochromatographic (GICA) strip was assembled. The analysis of Dot-ELISA and Western blot showed that the obtained three independent lines of mAbs 3A2, 5D2 and 5F7 specifically recognized TZSV N. Based on the assembly of GICA strip, the detection of TZSV was achieved by loading the infected sap onto the test strip for visual inspection. The analysis could be completed within 5-10 min. No cross-reaction occurred between TZSV and other tested viruses. The visual detection limit of the test strip for TZSV was 800 fold dilutions of TZSV-infected leaf samples. The mAbs were specific and the colloidal GICA strip developed in this study was convenient, fast and reliable for the detection of TZSV. The method could be applied for the rapid diagnosis and surveillance of TZSV in the field.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 January 2018.
All research outputs
#18,583,054
of 23,016,919 outputs
Outputs from Virology Journal
#2,455
of 3,061 outputs
Outputs of similar age
#330,840
of 441,922 outputs
Outputs of similar age from Virology Journal
#38
of 50 outputs
Altmetric has tracked 23,016,919 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,061 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 25.8. This one is in the 5th percentile – i.e., 5% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 441,922 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 50 others from the same source and published within six weeks on either side of this one. This one is in the 2nd percentile – i.e., 2% of its contemporaries scored the same or lower than it.
