A new variant of Croton yellow vein mosaic virus naturally infecting wild sunflower in India.

ABSTRACT: During 2015-2016, wild sunflower (Verbesina encelioides) was observed with bright yellow vein mosaic symptims in Noida, Uttar Pradesh, India. The initial analysis by PCR with a pair of coat protein based primers revealed the association of a begomovirus. Further, the virus was identified by rolling circle amplification and cloning of the complete genome. The DNA-A (2671 nucleotides, MH359168) with the genome organisation typical of the Old World begomovirus shared 98% sequence identity with that of Croton yellow vein mosaic virus (CYVMV) reported from India. The betasatellite (MH359169) associated with the disease shared 92% sequence identity with papaya leaf curl betasatellite (KY825245). The results showed that the wild sunflower is a new alternate host of CYVMV. The study also revealed a natural association of heterologous betasatellite with CYVMV in wild sunflower exhibiting yellow vein mosaic symptoms.

Identification and Functional Analysis of Four RNA Silencing Suppressors in Begomovirus Croton Yellow Vein Mosaic Virus.

Project description:Croton yellow vein mosaic virus (CYVMV), a species in the genus Begomovirus, is a prolific monopartite begomovirus in the Indian sub-continent. CYVMV infects multiple crop plants to cause leaf curl disease. Plants have developed host RNA silencing mechanisms to defend the threat of viruses, including CYVMV. We characterized four RNA silencing suppressors, namely, V2, C2, and C4 encoded by CYVMV and betasatellite-encoded C1 protein (βC1) encoded by the cognate betasatellite, croton yellow vein betasatellite (CroYVMB). Their silencing suppressor functions were verified by the ability of restoring the β-glucuronidase (GUS) activity suppressed by RNA silencing. We showed here for the first time that V2 was capable of self-interacting, as well as interacting with the V1 protein, and could be translocalized to the plasmodesmata in the presence of CYVMV. The knockout of either V2 or V1 impaired the intercellular mobility of CYVMV, indicating their novel coordinated roles in the cell-to-cell movement of the virus. As pathogenicity determinants, each of V2, C2, and C4 could induce typical leaf curl symptoms in Nicotiana benthamiana plants even under transient expression. Interestingly, the transcripts and proteins of all four suppressors could be detected in the systemically infected leaves with no correlation to symptom induction. Overall, our work identifies four silencing suppressors encoded by CYVMV and its cognate betasatellite and reveals their subcellular localizations, interaction behavior, and roles in symptom induction and intercellular virus movement.

Evidence of seed transmission of dolichos yellow mosaic virus, a begomovirus infecting lablab-bean in India.

Project description:Yellow mosaic disease in field bean caused by begomoviruses belonging to the family Geminiviridae is a major threat to the cultivation of crop in South India. Appearance of bright yellow mosaic symptom in emerging seedlings in farmers field was suggestive of seed transmission of the begomovirus associated with the disease which was investigated in the present study. The begomovirus causing yellow mosaic disease was identified as dolichos yellow mosaic virus (DoYMV) and the presence of DoYMV in matured seeds was confirmed by DAS-ELISA with OD value up to 3.268. In PCR with DoYMV specific primer (DoYMV-CP) the virus was detected in different parts of the seeds viz., seed coat, endosperm and embryo. In embryo the virus was detectable up to 100 per cent followed by endosperm (69.23%). When the non symptomatic leaves of 30 days old grow-out test plants were subjected to DAS-ELISA, the virus was detected up to 46.6%. This is the first evidence of seed transmission of DoYMV.

Agroinfection of tobacco by croton yellow vein mosaic virus and designing of a replicon vector for expression of foreign gene in plant.

Project description:Croton yellow vein mosaic virus (CYVMV, genus Begomovirus family Geminiviridae) is a proliferating begomovirus in the Indian sub-continent. The infectious constructs in binary vector was developed against the CYVMV genome and its associated betasatellite. Agroinoculation of the genomic construct of CYVMV produced leaf curl symptoms alone in three species of tobacco, Nicotiana tabacum, N. benthamiana and N. glutinosa. Co-inoculation of betasatellite enhanced the severity of the disease and reduced the incubation time. Based on the infectious clone, a replicon vector pCro, with only the ability to replicate inside the plant was developed. In pCro vector, CP and V2 ORFs from genome of CYVMV was deleted, which resulted localised replication of the molecule with no visible symptoms. Besides the partial CYVMV genome, pCro also has a cassette containing a double 35S promoter, multiple cloning sites and a NOS terminator to overexpress any foreign protein in plant. Episomal release of the replicon from the binary vector backbone after agroinoculation was detected by PCR. A GFP gene was cloned in pCro vector (pCro-GFP) and agroinoculated to N. tabacum resulted in localized expression of GFP at 5 dpi. The CYVMV replicon vector will be a useful tool for studying functional genomics, vaccine expression and gene silencing in plant.

New record of mungbean yellow mosaic India virus in Desmodium laxiflorum and association of bhendi yellow vein mosaic betasatellite in Abelmoschus moschatus in Andhra Pradesh, India.

Project description:Mungbean yellow mosaic India virus (MYMIV) is one of the most serious commonly occurring yellow mosaic virus (YMV's) group in majority of the pulses especially black gram and green gram in southern India compared to previously reported mungbean yellow mosaic virus. In January 2020 Desmodium laxiflorum and Abelmoscus moschatus showing mosaic symptoms and vein yellowing were collected from Guntur and Prakasam districts respectively in Andhra Pradesh. PCR analysis using MYMIV and betasatellite specific primers gave desired expected amplification from the infected samples of A. moschatus (YMV-ABEL) whereas only MYMIV specific amplification was obtained in D. laxiflorum (YMV-DES). However, no PCR amplification was obtained in respective healthy leaf samples of both plants. Sequence analysis showed that the CP sequence of YMV-ABEL and YMV-DES showed a similarity of 99.19% with MYMIV (KP677496) and 99.75% with MYMIV (JN181003) respectively. The full-length betasatellite (1356 bp) showed highest identity of 90% with bhendi yellow vein mosaic betasatellite (BYVMB) (GU111977). Phylogenetic analysis clustered the test isolates with south Indian isolates of MYMIV whereas the betasatellite sequence clustered with various isolates of BYVMB, tomato leaf curl New Delhi virus betasatellite and okra leaf curl betasatellite reported from India and Pakistan. To the best of our knowledge, this is the first report of a MYMIV in D. laxiflorum and A. moschatus and MYMIV betasatellite complex in A. moschatus.

Natural occurrence of mesta yellow vein mosaic virus and DNA-satellites in ornamental sunflower (Helianthus spp.) in Pakistan.

Project description:Weeds and ornamental plants serve as a reservoir for geminiviruses and contribute to their dissemination, genome recombination and/or satellite capture. Ornamental sunflower (Helianthus spp.) plants exhibiting mild leaf curl symptoms were subjected to begomovirus and DNA-satellites isolation. The full-length genome of the isolated begomovirus clone (Od1-A) showed 96.8% nucleotide (nt) sequence identity with mesta yellow vein mosaic virus (MeYVMV; accession no. FR772081) whereas, alphasatellite (Od1-a) and betasatellite (Od1-b) clones showed their highest nt sequence identities at 97.4% and 98.2% with ageratum enation alphasatellite (AEA; accession no. FR772085) and papaya leaf curl betasatellite (PaLCuB; accession. no. LN878112), respectively. The evolutionary relationships, average evolutionary divergence and the recombination events were also inferred. The MeYVMV exhibited 9.5% average evolutionary divergence and its CP and Rep had 9.3% and 12.2%, concomitantly; the alphasatellite and the betasatellite had 8.3% and 5.2%, respectively. The nt substitution rates (site-1 year-1) were found to be 6.983 × 10-04 and 5.702 × 10-05 in the CP and Rep of MeYVMV, respectively. The dN/dS ratio and the Tajima D value of MeYVMV CP demonstrated its possible role in host switching. The absolute quantification of the begomovirus demonstrated that mild symptoms might have a correlation with low virus titer. This is the first identification of MeYVMV and associated DNA-satellites from ornamental sunflower in Pakistan. The role of sequence divergence, recombination and importance of MeYVMV along with DNA-satellites in extending its host range is discussed.

Molecular and biological characterization of soybean yellow mottle mosaic virus severe strain infecting soybean in India.

Project description:The complete nucleotide sequence and genome organization of soybean yellow mottle mosaic virus severe strain causing bright yellow mosaic, mottling and puckering symptoms in soybean (Glycine max) from India was determined. The monopartite single stranded genomic RNA is 3974 nuclotides long and has the potential to encode six viral proteins viz., p25, p83, p8, p10, p39 and p25. The SYMMV-Sb isolate differed from mungbean strain with 69 nucleotides and nine aminoacids dispersed over the various ORFs. Comparative sequence analysis revealed that SYMMV-Sb shared 98% nt sequence identity at complete genome level and 96-100% at all ORFs level with SYMMV mungbean strain from India and 71-92% identity with SYMMV Korean soybean isolate, whereas it showed very low sequence identity with other tombusviridae members (2-53%). The phylogenetic analysis showed the clustering of SYMMV-Sb along with other members of genus Gammacarmovirus. The SYMMV-Sb isolate produced chlorotic blotches, mild and veinal mottling, necrosis and puckering symptoms in various leguminous host plants. The symptomatalogy of the soybean isolate was differed from mungbean strain as earlier induced severe symptoms on soybean and mild symptoms on mungbean.Supplementary informationThe online version contains supplementary material available at 10.1007/s13205-021-02925-2.

Diagnosis of a new variant of soybean yellow mottle mosaic virus with extended host-range in India.

Project description:Soybean yellow mottle mosaic virus (SYMMV, genus Carmovirus) was previously known to occur in South Korea and USA causing bright yellow mosaic in soybean. In this study, SYMMV (Car-Mb14 isolate) was isolated from mungbean (Vigna radiata) exhibiting mild mottling and puckering symptoms in the experimental field at Indian Agricultural Research Institute, New Delhi during 2012. The virus isolate, Car-Mb14 induced veinal mottling, mild mottling, chlorotic blotching, local and systemic necrosis in soybean, mungbean, blackgram, French bean and guar bean, respectively. The symptomatology of the present isolate of SYMMV was different from the previously reported South Korean isolate, as the later did not induce symptoms in any of the above legumes other than soybean. The present isolate was phylogenetically distinct and shared 90-93 % sequence identity in coat protein (CP) of 52 SYMMV isolates reported from Korea and USA. In order to know the serological relationships, the CP gene of the present isolate was over expressed as a 39 kDa protein in E. coli and an antiserum of 1:16,000 titer against the recombinant CP was produced. Serological cross reactivity analysis revealed that SYMMV was serologically related to blackgram mottle virus but not to cowpea mottle virus, the other legume infecting carmoviruses. The antiserum was used to detect prevalence of SYMMV in legume crops by ELISA. Out of 145 field samples of legumes (mungbean, blackgram, French bean and soybean) collected from different places in India, SYMMV was detected only in 16 samples of mungbean and one sample of blackgram. The natural infection of SYMMV in mungbean and blackgram was further confirmed based on CP gene sequence. This study provides evidence of occurrence of a new variant of SYMMV with distinct symptom phenotype and extended host-range in India.
