Cheng HW, Tsai WT, Hsieh YY, Chen KC, Yeh SD. Identification of a Common Epitope in Nucleocapsid Proteins of Euro-America Orthotospoviruses and Its Application for Tagging Proteins. Int J Mol Sci 2021; 22:ijms22168583. [PMID: 34445289 PMCID: PMC8395252 DOI: 10.3390/ijms22168583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 08/03/2021] [Accepted: 08/05/2021] [Indexed: 11/16/2022] Open
Abstract
The NSs protein and the nucleocapsid protein (NP) of orthotospoviruses are the major targets for serological detection and diagnosis. A common epitope of KFTMHNQIF in the NSs proteins of Asia orthotospoviruses has been applied as an epitope tag (nss-tag) for monitoring recombinant proteins. In this study, a monoclonal antibody TNP MAb against the tomato spotted wilt virus (TSWV) NP that reacts with TSWV-serogroup members of Euro-America orthotospoviruses was produced. By truncation and deletion analyses of TSWV NP, the common epitope of KGKEYA was identified and designated as the np sequence. The np sequence was successfully utilized as an epitope tag (np-tag) to monitor various proteins, including the green fluorescence protein, the coat protein of the zucchini yellow mosaic virus, and the dust mite chimeric allergen Dp25, in a bacterial expression system. The np-tag was also applied to investigate the protein-protein interaction in immunoprecipitation. In addition, when the np-tag and the nss-tag were simultaneously attached at different termini of the expressed recombinant proteins, they reacted with the corresponding MAbs with high sensitivity. Here, we demonstrated that the np sequence and TNP MAb can be effectively applied for tagging and detecting proteins and can be coupled with the nss-tag to form a novel epitope-tagging system for investigating protein-protein interactions.

Abstract
Chilli pepper (Capsicum annuum L.) is one of the most important crops in Yunnan Province, China. An orthotospovirus isolate 14YV855 was isolated from a diseased chilli pepper plant exhibiting yellow ringspots and necrosis on leaves in Shiping County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province in 2014. The complete genome sequence of 14YV855 was determined. The small, medium, and large RNAs are 3,428, 4,781, and 8,917 nucleotides long, respectively. The complete nucleocapsid (N) protein of 14YV855 shares a high amino acid identity of 84.8 to 89.9% to that of Capsicum chlorosis virus (CaCV), Groundnut bud necrosis virus (GBNV), Watermelon bud necrosis virus (WBNV), and Watermelon silver mottle virus (WSMoV), which is slightly less than the 90% identity threshold for the demarcation of new Orthotospovirus sp. Phylogenetic analyses revealed that the N protein and RNA-dependent RNA polymerase of 14YV855 are the most related to WSMoV, while the NSs, NSm, and Gn/Gc proteins are similar to those of GBNV. As expected, 14YV855 is serologically related to CaCV, GBNV, WBNV, and WSMoV when the monoclonal antibody against the N protein of WSMoV was used; however, 14YV855 can be distinguished from other orthotospoviruses by reverse-transcription PCR using the specific primers. Our results indicate that 14YV855 is a new Orthotospovirus sp. belonging to the WSMoV serogroup and is provisionally named Chilli yellow ringspot virus.

Characterization of the first complete genome sequence of an Impatiens necrotic spot orthotospovirus isolate from the United States and worldwide phylogenetic analyses of INSV isolates.

Abstract
OBJECTIVE Impatiens necrotic spot orthotospovirus (INSV) can impact economically important ornamental plants and vegetables worldwide. Characterization studies on INSV are limited. For most INSV isolates, there are no complete genome sequences available. This lack of genomic information has a negative impact on the understanding of the INSV genetic diversity and evolution. Here we report the first complete nucleotide sequence of a US INSV isolate. RESULTS INSV-UP01 was isolated from an impatiens in Pennsylvania, US. RT-PCR was used to clone its full-length genome and Vector NTI to assemble overlapping sequences. Phylogenetic trees were constructed by using MEGA7 software to show the phylogenetic relationships with other available INSV sequences worldwide. This US isolate has genome and biological features classical of INSV species and clusters in the Western Hemisphere clade, but its origin appears to be recent. Furthermore, INSV-UP01 might have been involved in a recombination event with an Italian isolate belonging to the Asian clade. Our analyses support that INSV isolates infect a broad plant-host range they group by geographic origin and not by host, and are subjected to frequent recombination events. These results justify the need to generate and analyze complete genome sequences of orthotospoviruses in general and INSV in particular.

Abstract
Through sequencing and assembly of small RNAs, an orthotospovirus was identified from a celtuce plant (Lactuca sativa var. augustana) showing vein clearing and chlorotic spots in the Zhejiang province of China. The S, M, and L RNAs of this orthotospovirus were determined to be 3146, 4734, and 8934 nt, respectively, and shared 30.4-72.5%, 43.4-80.8%, and 29.84-82.9% nucleotide sequence identities with that of known orthotospoviruses. The full length nucleoprotein (N) of this orthotospovirus shared highest amino acid sequence identity (90.25%) with that of calla lily chlorotic spot virus isolated from calla lily (CCSV-calla) [China: Taiwan: 2001] and tobacco (CCSV-LJ1) [China: Lijiang: 2014]. Phylogenetic analyses showed that this orthotospovirus is phylogenetically associated with CCSV isolates and clustered with CCSV, tomato zonate spot virus (TZSV), and tomato necrotic spot-associated virus (TNSaV) in a separate sub-branch. These results suggest that this orthotospovirus is a divergent isolate of CCSV and was thus named CCSV-Cel [China: Zhejiang: 2017].

Abstract
A Luminex xTAG-based assay for plant-infecting tospoviruses was developed. The test enables the detection of tospoviruses in general and the differentiation of the four important member species of this genus: Tomato spotted wilt virus, Impatiens necrotic spot virus, the proposed 'Capsicum chlorosis virus' and Watermelon silver mottle virus. The generic tospovirus primers used in this method are also applicable for detection of tospoviruses by basic RT-PCR. We also describe an economic alternative method for the distinction of the four tospoviruses mentioned and of additional member viruses, based on a restriction fragment length polymorphism (RFLP). The sophisticated Luminex xTAG technology allows the simultaneous detection of various targets. This study is part of a project that aims to develop a method for the simultaneous detection of various plant pathogens (viral, bacterial and fungal) in plant material.

BACKGROUND The thrips-borne tospoviruses Calla lily chlorotic spot virus (CCSV), Tomato zonate spot virus (TZSV) and a new species provisionally named Tomato necrotic spot associated virus (TNSaV) infect similar crops in southwestern China. The symptoms exhibiting on virus-infected crops are similar, which is difficult for distinguishing virus species by symptomatology. The sequences of nucleocapsid proteins (NPs) of CCSV, TNSaV and TZSV share high degrees of amino acid identity with each other, and their serological relationship was currently demonstrated from the responses of the previously reported monoclonal antibodies (MAbs) against the NP of CCSV (MAb-CCSV-NP) and the nonstructural NSs protein of Watermelon silver mottle virus (WSMoV) (MAb-WNSs). Therefore, the production of virus-specific antibodies for identification of CCSV, TNSaV and TZSV is demanded to improve field surveys. METHODS The NP of TZSV-13YV639 isolated from Crinum asiaticum in Yunnan Province, China was bacterially expressed and purified for producing MAbs. Indirect enzyme-linked immunosorbent assay (ELISA) and immunoblotting were conducted to test the serological response of MAbs to 18 tospovirus species. Additionally, the virus-specific primers were designed to verify the identity of CCSV, TNSaV and TZSV in one-step reverse transcription-polymerase chain reaction (RT-PCR). RESULTS Two MAbs, denoted MAb-TZSV-NP(S15) and MAb-TZSV-NP(S18), were screened for test. MAb-TZSV-NP(S15) reacted with CCSV and TZSV while MAb-TZSV-NP(S18) reacted specifically to TZSV in both indirect ELISA and immunoblotting. Both MAbs can be used to detect TZSV in field-collected plant samples. The epitope of MAb-TZSV-NP(S18) was further identified consisting of amino acids 78-86 (HKIVASGAD) of the TZSV-13YV639 NP that is a highly conserved region among known TZSV isolates but is distinct from TNSaV and TZSV. CONCLUSIONS In this study, two MAbs targeting to different portions of the TZSV NP were obtained. Unlike MAb-CCSV-NP reacted with TNSaV as well as CCSV and TZSV, both TZSV MAbs can be used to differentiate CCSV, TNSaV and TZSV. The identity of CCSV, TNSaV and TZSV was proven by individual virus-specific primer pairs to indicate the correctness of serological responses. We also proposed an serological detection platform using MAb-CCSV-NP, MAb-TZSV-NP(S15) and MAb-TZSV-NP(S18) to allow researchers and quarantine staff to efficiently diagnose the infections of CCSV, TNSaV and TZSV in China and other countries.

Abstract
BACKGROUND Tomato spotted wilt virus (TSWV) and Tomato zonate spot virus (TZSV) are the two dominant species of thrip-transmitted tospoviruses, cause significant losses in crop yield in Yunnan and its neighboring provinces in China. TSWV and TZSV belong to different serogroup of tospoviruses but induce similar symptoms in the same host plant species, which makes diagnostic difficult. We used different electron microscopy preparing methods to investigate clustering and cellular distribution of TSWV and TZSV in the host plant species. RESULTS Negative staining of samples infected with TSWV and TZSV revealed that particles usually clustered in the vesicles, including single particle (SP), double particles clustering (DPC), triple particles clustering (TPC). In the immunogold labeling negative staining against proteins of TZSV, the antibodies against Gn protein were stained more strongly than the N protein. Ultrathin section and high pressure freeze (HPF)-electron microscopy preparations revealed that TSWV particles were distributed in the cisternae of endoplasmic reticulum (ER), filamentous inclusions (FI) and Golgi bodies in the mesophyll cells. The TSWV particles clustered as multiple particles clustering (MPC) and distributed in globular viroplasm or cisternae of ER in the top leaf cell. TZSV particles were distributed more abundantly in the swollen membrane of ER in the mesophyll cell than those in the phloem parenchyma cells and were not observed in the top leaf cell. However, TZSV virions were mainly present as single particle in the cytoplasm, with few clustering as MPC. CONCLUSION In this study, we identified TSWV and TZSV particles had the distinct cellular distribution patterns in the cytoplasm from different tissues and host plants. This is the first report of specific clustering characteristics of tospoviruses particles as well as the cellular distribution of TSWV particles in the FI and globular viroplasm where as TZSV particles inside the membrane of ER. These results indicated that tospoviruses particles possessed specific and similar clustering in the saps of diseased plants. Furthermore, the results of this study will also provide a basis for further study on the tospoviruses assembling, maturation and movement.

Abstract
The first complete genome sequence of calla lily chlorotic spot virus (CCSV) from Lijiang in northwestern Yunnan Province was obtained using RT-PCR with designed primers. The genome of CCSV isolate LJ-1-Yunnan is tripartite. The small (S) RNA is 3182 nucleotides (nt) in length and encodes a nonstructural protein (NSs, 1383 nt) and a nuclear nucleocapsid (N, 834 nt), separated by an 836-nt intergenic region (IGR). The medium (M) RNA is 4749 nt in length and encodes a nonstructural movement protein (NSm, 930 nt) and a glycoprotein (GnGc, 3,372 nt), also separated by a 349-nt IGR. The large (L) RNA is 8912 nt in length and encodes a predicted RNA-dependent RNA polymerase (RdRp, 8652 nt). The nucleotide sequences of the three viral RNA segments are 92-94 % identical to the published CCSV genome sequence, and the amino acid sequences of the encoded proteins are 96-98 % identical. However, the IGRs of the S and M RNAs are less similar, with 86 and 72 % identity, respectively. Genome sequence comparisons and phylogenetic analysis indicate that the Lijiang CCSV isolate is a unique tospovirus isolate that differs from CCSV isolates in other geographic regions.

Abstract
Thrips-borne tospoviruses cause severe damage to crops worldwide. In this investigation, tobacco lines transgenic for individual WLm constructs containing the conserved motifs of the L RNA-encoded RNA-dependent RNA polymerase (L) gene of Watermelon silver mottle virus (WSMoV) were generated by Agrobacterium-mediated transformation. The WLm constructs included: (i) translatable WLm in a sense orientation; (ii) untranslatable WLmt with two stop codons; (iii) untranslatable WLmts with stop codons and a frame-shift; (iv) untranslatable antisense WLmA; and (v) WLmhp with an untranslatable inverted repeat of WLm containing the tospoviral S RNA 3'-terminal consensus sequence (5'-ATTGCTCT-3') and an NcoI site as a linker to generate a double-stranded hairpin transcript. A total of 46.7-70.0% transgenic tobacco lines derived from individual constructs showed resistance to the homologous WSMoV; 35.7-100% plants of these different WSMoV-resistant lines exhibited broad-spectrum resistance against four other serologically unrelated tospoviruses Tomato spotted wilt virus, Groundnut yellow spot virus, Impatiens necrotic spot virus and Groundnut chlorotic fan-spot virus. The selected transgenic tobacco lines also exhibited broad-spectrum resistance against five additional tospoviruses from WSMoV and Iris yellow spot virus clades, but not against RNA viruses from other genera. Northern analyses indicated that the broad-spectrum resistance is mediated by RNA silencing. To validate the L conserved region resistance in vegetable crops, the constructs were also used to generate transgenic tomato lines, which also showed effective resistance against WSMoV and other tospoviruses. Thus, our approach of using the conserved motifs of tospoviral L gene as a transgene generates broad-spectrum resistance against tospoviruses at the genus level.

Abstract
In this study, a multiplex RT-PCR-ELISA was developed to detect and differentiate four tospovirus species found in Thailand, namely Capsicum chlorosis virus (CaCV), Melon yellow spot virus (MYSV), Tomato necrotic ringspot virus (TNRV), and Watermelon silver mottle virus (WSMoV). In this system, nucleocapsid (N) gene fragments of four tospoviruses were simultaneously amplified and labeled with digoxigenin (DIG) in a single RT-PCR reaction using a pair of degenerate primers binding to the same conserved regions in all four tospovirus N genes. The DIG-labeled amplicons were distinguished into species by four parallel hybridizations to species-specific biotinylated probes in streptavidin-coated microtiter wells followed by ELISA detection using a peroxidase-conjugated anti-DIG antibody. Results indicated that the multiplex RT-PCR-ELISA assay could specifically identify each of these four tospoviruses without cross-reactivity between species or reactivity to healthy plant negative controls. Assay sensitivity was 10- to 1000-fold higher than conventional RT-PCR. When applied to naturally infected plants, all samples yielded concordant results between RT-PCR-ELISA and the reference RT-PCR. In conclusion, the multiplex RT-PCR-ELISA developed in this study has superior specificity, sensitivity, and high-throughput capacity compared to conventional RT-PCR and is an attractive alternative for the identification of different tospovirus species.

Abstract
NSscon (23 aa), a common epitope in the gene silencing suppressor NSs proteins of the members of the Watermelon silver mottle virus (WSMoV) serogroup, was previously identified. In this investigation, we expressed different green fluorescent protein (GFP)-fused deletions of NSscon in bacteria and reacted with NSscon monoclonal antibody (MAb). Our results indicated that the core 9 amino acids, "(109)KFTMHNQIF(117)", denoted as "nss", retain the reactivity of NSscon. In bacterial pET system, four different recombinant proteins labeled with nss, either at N- or C-extremes, were readily detectable without position effects, with sensitivity superior to that for the polyhistidine-tag. When the nss-tagged Zucchini yellow mosaic virus (ZYMV) helper component-protease (HC-Pro) and WSMoV nucleocapsid protein were transiently expressed by agroinfiltration in tobacco, they were readily detectable and the tag's possible efficacy for gene silencing suppression was not noticed. Co-immunoprecipitation of nss-tagged and non-tagged proteins expressed from bacteria confirmed the interaction of potyviral HC-Pro and coat protein. Thus, we conclude that this novel nss sequence is highly valuable for tagging recombinant proteins in both bacterial and plant expression systems.

Abstract
Melon yellow spot virus (MYSV), a tentative member of the genus Tospovirus, is considered a distinct serotype due to the lack of a serological relationship with other tospoviruses in its nucleocapsid protein (NP). Recently, a virus isolate collected from diseased watermelon in central Taiwan (MYSV-TW) was found to react with a rabbit antiserum (RAs) prepared against the NP of Watermelon silver mottle virus (WSMoV), and a monoclonal antibody (MAb) prepared against the common epitope of the NSs proteins of WSMoV-serogroup tospoviruses, but not with the WSMoV NP-specific MAb, in both enzyme-linked immunosorbent assay (ELISA) and western blotting. In this investigation, both RAs and MAb against MYSV-TW NP were produced. Results of serological tests revealed that the RAs to MYSV-TW NP reacted with the homologous antigen and the crude antigens of members of the WSMoV serogroup, including members of the formal species WSMoV and Peanut bud necrosis virus, and members of three tentative species, Watermelon bud necrosis virus, Capsicum chlorosis virus and Calla lily chlorotic spot virus. The MAb to MYSV-TW NP reacted only with the homologous antigen and the other geographic isolates of MYSV from Japan (JP) and Thailand (TH). Our results of reciprocal tests indicate that the NP and the NSs protein of MYSV are serologically related to those of WSMoV-serogroup tospoviruses. Furthermore, we show that both the MYSV NP MAb and the WSMoV NP MAb are reliable tools for identification of MYSV and WSMoV from single or mixed infection in field surveys, as verified using species-specific primers in reverse transcription-polymerase chain reaction.

Abstract
A tospovirus causing necrotic streaks on leaves was isolated from Alstroemeria sp. in Colombia. Infected samples reacted positively with tomato spotted wilt virus (TSWV) antiserum during preliminary serological tests. Further analysis revealed a close serological relationship to tomato chlorotic spot virus (TCSV) and groundnut ringspot virus (GRSV). A major part of the S-RNA segment, encompassing the nucleocapsid (N) protein gene, the 5′ untranslated region and a part of the intergenic region 3′ of the N gene, was cloned and sequenced. The deduced N protein sequence showed highest amino acid identity (82%) to that of TCSV, indicating that the virus represents a new tospovirus species, for which the name Alstroemeria necrotic streak virus (ANSV) is coined. Phylogenetic analysis based on the N protein sequence revealed that this Alstroemeria-infecting tospovirus clustered with tospoviruses from the American continent. Frankliniella occidentalis was identified as potential vector species for ANSV.

Abstract
The structure and organization of the large (L) RNA of iris yellow spot virus (IYSV) was determined, and with this report, the complete genomic sequence of IYSV of the genus Tospovirus, family Bunyaviridae has been elucidated. The L RNA of IYSV was 8,880 nucleotides in length and contained a single open reading frame in the viral complementary (vc) strand. The primary translation product of 331.17 kDa shared many of the features of the viral RNA-dependent RNA polymerase (RdRp) coded by L RNAs of known tospoviruses. The 5' and 3' termini of IYSV L RNA (vc) contain two untranslated regions of 33 and 226 nucleotides, respectively, and both termini have conserved terminal nucleotides, another common feature of tospovirus genomic RNAs. Conserved motifs characteristic of RdRps of members of the family Bunyaviridae were present in the IYSV RdRp.

Characterization of tomato zonate spot virus, a new tospovirus in China. Arch Virol 2008; 153:855-64. [PMID: 18320136 DOI: 10.1007/s00705-008-0054-5] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2007] [Accepted: 01/04/2008] [Indexed: 10/22/2022]
Abstract
An isolate of a new tospovirus species, causing concentric zoned ringspots on fruits and necrotic lesions on leaves of infected plants, was characterised based on particle morphology, host range and serological properties. The complete nucleotide sequences of large (L), medium (M), and small (S) RNAs of this virus were found to contain 8919, 4945, and 3279 nts respectively. The L RNA encoded the RNA-dependent RNA polymerase (RdRp) (2885 aa, 332.7 kDa). The M RNA encoded a non-structural (NSm) protein (309 aa, 34.4 kDa) and a viral glycoprotein precursor (Gn/Gc) (1122 aa, 127.4 kDa). The S RNA encoded a non-structural protein (NSs) (459 aa, 51.9 kDa) and the nucleocapsid (N) protein (278 aa, 30.6 kDa). This N protein shared amino acid identities of 80.9% with those of calla lily chlorotic spot virus. Our results suggest that the virus studied here belongs to a new tospovirus species, for which the name tomato zonate spot virus is proposed.

Abstract
Two tospoviruses, Chrysanthemum stem necrosis virus (CSNV) and Zucchini lethal chlorosis virus (ZLCV), cause economical losses in several ornamental and vegetable crops in Brazil. The nucleocapsid gene and movement protein sequences had already been reported for both viruses, though the glycoprotein precursor gene sequence was not available. In this study, cDNA fragments (ca. 4 kb) of the M RNA 3' portion of CSNV (isolate Chry-1) and ZLCV (isolate 1038), including the complete glycoprotein precursor gene, partial NSm gene, and the entire intergenic and 3' untranslated regions, were cloned and sequenced. The sequences were assembled with the corresponding 5' region sequence (NSm gene and 5'UTR) of the same isolates to build up the complete sequence of the M RNA segment of both species. The M RNA of CSNV was 4,828 nucleotide-long, while of ZLCV 4,836 nucleotides. Both M RNA molecules comprised two ORFs in an ambisense arrangement. The vcRNA coded for the viral glycoprotein (Gn/Gc) precursor gene of CSNV and ZLCV (both with 127.5 kDa). Comparison of deduced amino acids of the CSNV and ZLCV glycoprotein precursor genes with those of other tospoviruses showed the highest identity with that of Tomato spotted wilt virus (86%) and with that of CSNV (82%), respectively. However, the nucleotide sequence of the intergenic and 3' untranslated regions of CSNV and ZLCV shared lower identities with other tospoviruses. The glycoprotein precursor gene is thought to be a good candidate as additional classification parameter for Tospovirus taxonomy. The presence of the RGD motif in both Gc proteins indicated that they are typical American tospoviruses, which was confirmed by phylogenetic analysis. The membrane topology of both glycoproteins is discussed.

Abstract
ABSTRACT The NSs protein of Watermelon silver mottle virus (WSMoV) was expressed by a Zucchini yellow mosaic virus (ZYMV) vector in squash. The expressed NSs protein with a histidine tag and an additional NIa protease cleavage sequence was isolated by Ni(2+)-NTA resins as a free-form protein and further eluted after sodium dodecyl sulfate-polyacrylamide gel electrophoresis for production of rabbit antiserum and mouse monoclonal antibodies (MAbs). The rabbit antiserum strongly reacted with the NSs crude antigen of WSMoV and weakly reacted with that of a high-temperature-recovered gloxinia isolate (HT-1) of Capsicum chlorosis virus (CaCV), but not with that of Calla lily chlorotic spot virus (CCSV). In contrast, the MAbs reacted strongly with all crude NSs antigens of WSMoV, CaCV, and CCSV. Various deletions of the NSs open reading frame were constructed and expressed by ZYMV vector. Results indicate that all three MAbs target the 89- to 125-amino-acid (aa) region of WSMoV NSs protein. Two indispensable residues of cysteine and lysine were essential for MAbs recognition. Sequence comparison of the deduced MAbs-recognized region with the reported tospoviral NSs proteins revealed the presence of a consensus sequence VRKPGVKNTGCKFTMHNQIFNPN (denoted WNSscon), at the 98- to 120-aa position of NSs proteins, sharing 86 to 100% identities among those of WSMoV, CaCV, CCSV, and Peanut bud necrosis virus. A synthetic WNSscon peptide reacted with the MAbs and verified that the epitopes are present in the 98- to 120-aa region of WSMoV NSs protein. The WSMoV sero-group-specific NSs MAbs provide a means for reliable identification of tospoviruses in this large serogroup.

Abstract
The complete nucleotide sequence of a tospovirus isolated from Lycopersicum esculentum in Thailand was determined. The L RNA comprises of 8912 nt and codes for the RNA-dependent RNA-polymerase (RdRp) (2877 aa). Two ORFs are located on the M RNA (4823 nt) encoding the non-structural (NSm) protein (308 aa) and the viral glycoprotein precursors (Gn/Gc) (1121 aa) separated by an intergenic region of 433 nt. ORFs coding for the non-structural (NSs) and nucleocapsid (N) protein, 439 aa and 275 aa, respectively, were identified on the S RNA (3477 nt) separated by an intergenic region of 1202 nt. The N protein of the Thailand isolate was most closely related to that of capsicum chlorosis virus (CaCV), sharing an amino acid sequence identity of 92.7%. Additionally, multiple sequence analyses revealed significant similarities to tospoviruses of the species Watermelon silver mottle virus and to several putative tospovirus entries in GenBank. Based on these alignments it is proposed to refer to all these different viruses as isolates of CaCV.
