Highly repetitive DNA sequences found in HETEROCHROMATIN, mainly near centromeres. They are composed of simple sequences (very short) (see MINISATELLITE REPEATS) repeated in tandem many times to form large blocks of sequence. Additionally, following the accumulation of mutations, these blocks of repeats have been repeated in tandem themselves. The degree of repetition is on the order of 1000 to 10 million at each locus. Loci are few, usually one or two per chromosome. They were called satellites since in density gradients, they often sediment as distinct, satellite bands separate from the bulk of genomic DNA owing to a distinct BASE COMPOSITION.

DNA helicase activity is associated with the replication initiator protein rep of tomato yellow leaf curl geminivirus. (1/170)

The Rep protein of tomato yellow leaf curl Sardinia virus (TYLCSV), a single-stranded DNA virus of plants, is the replication initiator essential for virus replication. TYLCSV Rep has been classified among ATPases associated with various cellular activities (AAA+ ATPases), in superfamily 3 of small DNA and RNA virus replication initiators whose paradigmatic member is simian virus 40 large T antigen. Members of this family are DNA- or RNA-dependent ATPases with helicase activity necessary for viral replication. Another distinctive feature of AAA+ ATPases is their quaternary structure, often composed of hexameric rings. TYLCSV Rep has ATPase activity, but the helicase activity, which is instrumental in further characterization of the mechanism of rolling-circle replication used by geminiviruses, has been a longstanding question. We present results showing that TYLCSV Rep lacking the 121 N-terminal amino acids has helicase activity comparable to that of the other helicases: requirements for a 3' overhang and 3'-to-5' polarity of unwinding, with some distinct features and with a minimal AAA+ ATPase domain. We also show that the helicase activity is dependent on the oligomeric state of the protein.  (+info)

Synergism of a DNA and an RNA virus: enhanced tissue infiltration of the begomovirus Abutilon mosaic virus (AbMV) mediated by Cucumber mosaic virus (CMV). (2/170)

Replication of the begomovirus Abutilon mosaic virus (AbMV) is restricted to phloem nuclei, generating moderate levels of virus DNA. Co-infection with Cucumber mosaic virus (CMV) evidently increased AbMV titers in Nicotiana benthamiana, tobacco, and tomato, resulting in synergistic symptom enhancement. In situ hybridization revealed that in double-infected leaves an increased number of nuclei contained elevated amounts of AbMV. Additionally, the begomoviral phloem-limitation was broken. Whereas CMV 3a movement protein-expressing tobacco plants did not exert any similar influence, the presence of CMV 2b silencing suppressor protein lead to enhanced AbMV titers and numbers of infected vascular cells. The findings prove that AbMV can replicate in nonvascular cells and represent the first report on a true synergism of an RNA/ssDNA virus combination in plants, in which CMV 2b protein plays a role. They indicate considerable consequences of mixed infections between begomo- and cucumoviruses on virus epidemiology and agriculture.  (+info)

Suppressor of RNA silencing encoded by Tomato yellow leaf curl virus-Israel. (3/170)

The Israeli isolate of Tomato yellow leaf curl geminivirus (TYLCV-Is) is a major tomato pathogen, causing extensive crop losses both in the New and Old World. Surprisingly, however, little is known about the molecular mechanisms of TYLCV-Is interactions with tomato cells. Here, we have identified a TYLCV-Is protein, V2, which acts as a suppressor of RNA silencing and which is unrelated to presently known viral suppressors. Specifically, V2, but not other proteins of TYLCV-Is, inhibited RNA silencing of a reporter transgene, GFP. This inhibition elevated the cellular levels of the GFP transcript and the GFP protein, but it had no apparent effect on the accumulation of GFP-specific short interfering RNAs (siRNAs), suggesting that TYLCV-Is V2 targets a step in the RNA silencing pathway which is subsequent to the Dicer-mediated cleavage of dsRNA. Visualization of the sub-cellular localization of TYLCV-Is V2 in plant protoplasts and tissues showed that this protein is associated with cytoplasmic strands and inclusion bodies in the cortical regions of the cell.  (+info)

Founder effect, plant host, and recombination shape the emergent population of begomoviruses that cause the tomato yellow leaf curl disease in the Mediterranean basin. (4/170)

Tomato yellow leaf curl disease (TYLCD)-associated viruses present a highly structured population in the western Mediterranean basin, depending on host, geographical region and time. About 1,900 tomato and common bean samples were analyzed from which 111 isolates were characterized genetically based on a genome sequence that comprises coding and non-coding regions. Isolates of three distinct begomoviruses previously described were found (Tomato yellow leaf curl virus, TYLCV, Tomato yellow leaf curl Sardinia virus, TYLCSV, and Tomato yellow leaf curl Malaga virus, TYLCMalV), together with a novel recombinant virus. Mixed infections were detected in single plants, rationalizing the occurrence of recombinants. Except for TYLCV-type strain, single, undifferentiated subpopulations were present for each virus type, probably the result of founder effects. Limited genetic variation was observed in genomic regions, with selection against amino acid change in coding regions.  (+info)

Tomato yellow spot virus, a tomato-infecting begomovirus from Brazil with a closer relationship to viruses from Sida sp., forms pseudorecombinants with begomoviruses from tomato but not from Sida. (5/170)

Geminiviruses are characterized by a circular, single-stranded DNA genome and twinned icosahedral particles. Begomoviruses (whitefly-transmitted geminiviruses) are a major constraint to crop production worldwide. In Brazil, tomato-infecting begomoviruses emerged as serious pathogens over the last 10 years, due to the introduction of a new biotype of the insect vector. Tomato yellow spot virus (ToYSV) is a newly described begomovirus originally isolated from tomato, but phylogenetically closer to viruses from Sida sp. A study was performed to determine the viability of pseudorecombinants formed between the DNA components of ToYSV and other weed- and tomato-infecting begomoviruses from Brazil. Despite its closer relationship to weed-infecting viruses, ToYSV was only capable of forming viable pseudorecombinants with tomato viruses. An infectious pseudorecombinant formed between ToYSV DNA-A and tomato crinkle leaf yellows virus (TCrLYV) DNA-B induced severe symptoms in Nicotiana benthamiana. This was attributed, at least in part, to the fact that the origins of replication of both components had identical Rep-binding sequences. However, this was not the case for another infectious pseudorecombinant formed between tomato golden mosaic virus (TGMV) DNA-A and ToYSV DNA-B, which have different Rep-binding sequences. These results reinforce the notion that pseudorecombinant formation cannot be explained solely on the basis of phylogenetic relationships and conserved iteron sequences, and suggest that the TGMV Rep protein may be more versatile in terms of recognizing heterologous DNA components than that of ToYSV.  (+info)

Tomato chlorotic mottle virus is a target of RNA silencing but the presence of specific short interfering RNAs does not guarantee resistance in transgenic plants. (6/170)

Tomato chlorotic mottle virus (ToCMoV) is a begomovirus found widespread in tomato fields in Brazil. ToCMoV isolate BA-Se1 (ToCMoV-[BA-Se1]) was shown to trigger the plant RNA silencing surveillance in different host plants and, coinciding with a decrease in viral DNA levels, small interfering RNAs (siRNAs) specific to ToCMoV-[BA-Se1] accumulated in infected plants. Although not homogeneously distributed, the siRNA population in both infected Nicotiana benthamiana and tomato plants represented the entire DNA-A and DNA-B genomes. We determined that in N. benthamiana, the primary targets corresponded to the 5' end of AC1 and the embedded AC4, the intergenic region and 5' end of AV1 and overlapping central part of AC5. Subsequently, transgenic N. benthamiana plants were generated that were preprogrammed to express double-stranded RNA corresponding to this most targeted portion of the virus genome by using an intron-hairpin construct. These plants were shown to indeed produce ToCMoV-specific siRNAs. When challenge inoculated, most transgenic lines showed significant delays in symptom development, and two lines had immune plants. Interestingly, the levels of transgene-produced siRNAs were similar in resistant and susceptible siblings of the same line. This indicates that, in contrast to RNA viruses, the mere presence of transgene siRNAs corresponding to DNA virus sequences does not guarantee virus resistance and that other factors may play a role in determining RNA-mediated resistance to DNA viruses.  (+info)

The oligomeric Rep protein of Mungbean yellow mosaic India virus (MYMIV) is a likely replicative helicase. (7/170)

Geminiviruses replicate by rolling circle mode of replication (RCR) and the viral Rep protein initiates RCR by the site-specific nicking at a conserved nonamer (TAATATT downward arrow AC) sequence. The mechanism of subsequent steps of the replication process, e.g. helicase activity to drive fork-elongation, etc. has largely remained obscure. Here we show that Rep of a geminivirus, namely, Mungbean yellow mosaic India virus (MYMIV), acts as a replicative helicase. The Rep-helicase, requiring > or =6 nt space for its efficient activity, translocates in the 3'-->5' direction, and the presence of forked junction in the substrate does not influence the activity to any great extent. Rep forms a large oligomeric complex and the helicase activity is dependent on the oligomeric conformation ( approximately 24mer). The role of Rep as a replicative helicase has been demonstrated through ex vivo studies in Saccharomyces cerevisiae and in planta analyses in Nicotiana tabacum. We also establish that such helicase activity is not confined to the MYMIV system alone, but is also true with at least two other begomoviruses, viz., Mungbean yellow mosaic virus (MYMV) and Indian cassava mosaic virus (ICMV).  (+info)

Distinct viral sequence elements are necessary for expression of Tomato golden mosaic virus complementary sense transcripts that direct AL2 and AL3 gene expression. (8/170)

Transient expression studies using Nicotiana benthamiana protoplasts and plants have identified sequences important for transcription of complementary sense RNAs derived from Tomato golden mosaic virus (TGMV) DNA component A that direct expression of AL2 and AL3. Transcription of two complementary sense RNAs, initiating at nucleotides 1,935 (AL1935) and 1,629 (AL1629), is directed by unique sequences located upstream of each transcription initiation site. One element is located between 28 and 124 nucleotides (nt) upstream of the AL1935 transcription start site, which differs from a second element located 150 nt downstream, between 129 and 184 nt upstream of the AL1629 transcription start site. Transcription initiation at nucleotide 1,935 is lower than that at nucleotide 1,629 as determined by run-on transcription assays, and the resulting transcript is only capable of expressing AL3. The transcript initiating at nucleotide 1,629 is capable of directing expression of both AL2 and AL3, although expression of AL3 is up to fourfold greater than that for AL2. Nuclear factors purified from tobacco suspension cells bind to sequences upstream of both AL1935 and AL1629, correlating with the ability of these sequences to direct gene expression. Thus, in tobacco, regulatory sequences direct transcription of two unique TGMV messenger RNAs that differentially express AL2 and AL3.  (+info)

Begomoviruses have emerged as serious problem for vegetable and fiber crops in the recent past, frequently in tropical and subtropical region of the world. The association of begomovirus with eggplant yellow mosaic disease is hitherto unknown apart from one report from Thailand. A survey in Nagpur, Central India, in 2009-2010 showed severe incidence of eggplant yellow mosaic disease. Here, we have identified and characterized a begomovirus responsible for the newly emerging yellow mosaic disease of eggplant in India. The complete DNA-A and DNA-B genomic components of the causative virus were cloned and sequenced. Nucleotide sequence analysis of DNA-A showed that it shared highest 97.6% identity with Tomato leaf curl New Delhi virus-India[India:Udaipur:Okra:2007] and lowest 87.9% identity with Tomato leaf curl New Delhi virus-India[India:NewDelhi:Papaya:2005], while DNA-B showed highest 94.1% identity with ToLCNDV-IN[IN:UD:Ok:07] and lowest 76.2% identity with ToLCNDV-India[India:Lucknow]. Thus, it
Tomato yellow leaf curl virus (TYLCV) is a DNA virus from the genus Begomovirus and the family Geminiviridae. TYLCV causes the most destructive disease of tomato, and it can be found in tropical and subtropical regions causing severe economic losses. This virus is transmitted by an insect vector from the family Aleyrodidae and order Hemiptera, the whitefly Bemisia tabaci, commonly known as the silverleaf whitefly or the sweet potato whitefly. The primary host for TYLCV is the tomato plant, and other plant hosts where TYLCV infection has been found include eggplants, potatoes, tobacco, beans, and peppers. Due to the rapid spread of TYLCV in the last few decades, there is an increased focus in research trying to understand and control this damaging pathogen. Some interesting findings include virus being sexually transmitted from infected males to non-infected females (and vice versa), and an evidence that TYLCV is transovarially transmitted to offspring for two generations. This virus consists of ...

Plant receptor-like kinases (RLKs) exert an essential function in the transduction of signals from the cell exterior to the cell interior, acting as important regulators of plant development and responses to environmental conditions. A growing body of evidence suggests that RLKs may play relevant roles in plant-virus interactions, although the details and diversity of effects and underlying mechanisms remain elusive. The C4 protein from different geminiviruses has been found to interact with RLKs in the CLAVATA 1 (CLV1) clade. However, whether C4 can interact with RLKs in other subfamilies and, if so, what the biological impact of such interactions might be, is currently unknown. In this work, we explore the interaction landscape of C4 from the geminivirus Tomato yellow leaf curl virus within the Arabidopsis RLK family. Our results show that C4 can interact with RLKs from different subfamilies including, but not restricted to, members of the CLV1 clade. Functional analyses of the interaction of C4 with
Whitefly-transmitted geminiviruses (begomoviruses) are a major limiting factor for the production of numerous dicotyledonous crops throughout the world. Begomoviruses differ in the number of components that make up their genomes and association with satellites, and yet they cause strikingly similar phenotypes, such as leaf curling, chlorosis and stunted plant growth. MicroRNAs (miRNAs) are small endogenous RNAs that regulate plant growth and development. The study described here was aimed at investigating the effects of each virus encoded gene on the levels of developmental miRNAs to identify common trends between distinct begomoviruses. All genes encoded by four distinct begomoviruses (African cassava mosaic virus [ACMV], Cabbage leaf curl virus [CbLCuV], Tomato yellow leaf curl virus [TYLCV] and Cotton leaf curl virus/Cotton leaf curl betasatellite [CLCuV/CLCuMB]) were expressed from a Potato virus X (PVX) vector in Nicotiana benthamiana.

Surveys were conducted during 2016-18 revealed that the occurrence of the leaf curl disease on tobacco in major growing districts of Karnataka ranged from 19.60 to 31.01 during 2016-18. Among the six districts surveyed, highest per cent disease incidence of tobacco leaf curl virus was recorded in Shivamogga district (31.01) followed by Belagavi (25.59) and lowest per cent disease incidence of 19.60 of TbLCV was recorded in Chamarajangar district. The survey data imply that leaf curl disease is emerging as one of the major diseases of tobacco. For the detection of the virus, total DNA was extracted and PCR was carried out using pair of begomovirus specific Deng primers. All the isolates collected at different locations showed characteristic band of 550 bp whereas no amplicon was observed in healthy tobacco samples.

Table_1_A Begomovirus Nuclear Shuttle Protein-Interacting Immune Hub: Hijacking Host Transport Activities and Suppressing Incompatible Functions.XLSX
Geminiviruses are serious plant pathogens infecting dicotyledonous plants, among them important crop plants. They are characterized by small geminate particles containing single-stranded circular DNA molecules. Because geminiviruses replicate in the nucleus, viral DNA has to cross the nuclear envelope and the plasmodesmata for systemic spread. Two genes are required for inter- and intracellular transport of bipartite begomoviruses: ORF BV1 (syn. BR1) encodes a nuclear shuttle protein (NSP), and ORF BC1 (syn. BL1) the movement protein (MP). The mechanism of geminiviral intra- and intercellular transport is still a matter of debate and the transport complex is unknown. We want to identify host factors involved in viral intra- and intercellular transport by a proteomic approach to gain further insight in the underlying mechanism of virus movement. ...
Geminiviruses infect crops, ornamentals and weeds and cause substantial agro-economical losses around the world. The incidence and severity of geminivirus diseases has greatly increased in the past 20 years. The family Geminiviridae is one of the largest and most important families of plant viruses. The DNA genomes of geminiviruses encode only for 5-7 proteins that redirect host machineries and processes to establish a productive infection. These interactions reprogram plant cell cycle and transcriptional controls, inhibit cell death pathways, interfere with cell signaling and protein turnover, and suppress defense. The genome of bipartite begomoviruses (family Geminiviridae) consists of two circular ssDNA molecules: DNA A and DNA B. Both genome components are relatively small (2.5 - 3.0 kb per single-stranded DNA circle) and replicate within the plant nucleus. Thus, systemic infection requires the permeation across two cellular barriers, the nuclear envelope and plasmodesmata. The two DNA ...

Tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite whitefly transmitted begomovirus, responsible since 2013 of severe damages in cucurbit crops in Southeastern Spain. Zucchini (Cucurbita pepo) is the most affected species, but melon (Cucumis melo) and cucumber (Cucumis sativus) are also highly damaged by the infection. The virus has spread across Mediterranean basin and European countries, and integrated control measures are not being enough to reduce economic losses. The identification of resistance genes is required to develop resistant cultivars. In this assay, we studied the inheritance of the resistance to ToLCNDV previously identified in two Cucurbita moschata accessions. We generated segregating populations crossing both resistant pumpkins, an American improved cultivar Large Cheese (PI 604506) and an Indian landrace (PI 381814), with a susceptible C. moschata genotype (PI 419083). The analysis of symptoms and viral titers of all populations established the same monogenic recessive genetic
During the last few decades, many virus species have emerged, often forming dynamic complexes within which viruses share common hosts and rampantly exchange genetic material through recombination. Begomovirus species complexes are common and represent serious agricultural threats. Characterization of species complex diversity has substantially contributed to our understanding of both begomovirus evolution, and the ecological and epidemiological processes involved in the emergence of new viral pathogens. To date, the only extensively studied emergent African begomovirus species complex is that responsible for cassava mosaic disease. Here we present a study of another emerging begomovirus species complex which is associated with serious disease outbreaks in bean, tobacco and tomato on the south-west Indian Ocean (SWIO) islands off the coast of Africa. On the basis of 14 new complete DNA-A sequences, we describe seven new island monopartite begomovirus species, suggesting the presence of an extraordinary
Severe mosaic symptoms, accompanied by yellow spots, abnormally small leaves, fruit malformation and cracking, reduced plant growth, and high levels of whitefly (Bemisia tabaci MEAM1) infestation were observed in passionflower (Passiflora edulis) orchards in southwestern Bahia, Brazil. The aim of this work was to identify the species of begomovirus infecting the passionflowers, its prevalence in southwestern Bahia, and the spatial and temporal dynamics of the disease. Leaf samples from symptomatic plants collected at 57 orchards located in ten counties were evaluated by PCR for begomovirus infection. Complete nucleotide sequences of DNA-A for two isolates revealed 97 % identity with Passionfruit severe leaf distortion virus (PSLDV). The occurrence of PSLDV in 57 orchards was evaluated based on the presence of characteristic disease symptoms. Approximately 235,000 visually assessed plants exhibited symptoms characteristic of begomovirus infection. Epidemiological studies, conducted in two ...

Geminiviruses constitute a group of plant viruses that infect vegetable crops all over the world. Among the Geminiviridae family, the genera Mastrevirus, Begomovirus and Curtovirus are the most abundant. Suppression of gene silencing is a key mechanism for viral infection in plants. In begomovirus, V2 is a strong posttranscriptional gene silencing suppressor. We recently showed that, despite the lack of sequence homology with V2 from begomovirus, V2 from curtovirus Beet curly top virus (BCTV) is also a PTGS suppressor by impairing the RDR6/SGS3 pathway. In order to identify the domains involved the suppression activity and viral pathogenicity, we analysed the aminoacidic sequence, performing an alignment of several begomovirus and curtovirus V2 proteins. A protein kinase C (PKC) phosphorylation motif essential for suppression activity in begomovirus (P1) was founded in a similar position in all analysed sequences. Besides, other two putative CK2 and PKC phosphorilation motifs (P2 and P3) were ...
Conclusions and Recommendations. The study revealed that three viruses, TMV, begomovirus and TEV, were associated with viral disease outbreaks in tomato in Trinidad in 2003. The other viruses tested for (CMV, PVY, PLRV, and TSWV) were not detected, which indicates that that they were absent, occurred at too low a frequency or in titers too low to be detected by the sampling and/or testing method employed in this study. As this survey was conducted only in the dry season and in a single year (2003), a role for the other viruses in tomato viral disease in Trinidad cannot be ruled out. The results indicated an overall high incidence of begomovirus infection. This suggests that begomovirus(es) may be the most important viral pathogen in tomato in Trinidad. As there no detected weed hosts of begomovirus (PYMTV) detected in Trinidad (16), it is likely that infected tomato plants are the primary inoculum source for begomovirus. This is also supported by a failure to detect virus infection in ...

The LBR:GFP marker was used in transient expression experiments in tobacco plants to visualize the plant nuclear envelope (PNE). The LBR:GFP marker consists of the first 238 amino acids of the human lamin B receptor (LBR), fused to the green fluorescent protein (GFP). GFP fluorescence accumulated only at the PNE of leaf epidermal cells, although plants do not possess any lamin proteins. Abutilon mosaic virus (AbMV; genus begomovirus) induce alteration of plant nuclear architecture which can be monitored by the LBR:GFP marker. Co-expression experiments have shown that the two transport proteins of AbMV (MP and NSP) are responsible for those alterations, e.g. intense necking, vesicle formation and budding. Successful LBR:GFP targeting anchoring in PNE suggests, that underlying mechanism may be common in plants and humans. We predicted that NSP and MP also re-localize LBR in the human cell and therefore we addressed the question and investigate if the begomoviral transport proteins also have a ...

Geminiviruses are small DNA viruses that use plant replication machinery to amplify their genomes. Microarray analysis of the Arabidopsis (Arabidopsis thaliana) transcriptome in response to cabbage leaf curl virus (CaLCuV) infection uncovered 5,365 genes (false discovery rate ,0.005) differentially expressed in infected rosette leaves at 12 d postinoculation. Data mining revealed that CaLCuV triggers a pathogen response via the salicylic acid pathway and induces expression of genes involved in programmed cell death, genotoxic stress, and DNA repair. CaLCuV also altered expression of cell cycle-associated genes, preferentially activating genes expressed during S and G2 and inhibiting genes active in G1 and M. A limited set of core cell cycle genes associated with cell cycle reentry, late G1, S, and early G2 had increased RNA levels, while core cell cycle genes linked to early G1 and late G2 had reduced transcripts. Fluorescence-activated cell sorting of nuclei from infected leaves revealed a ...
Geminivirus AC2 is a multifunctional protein that acts as a pathogenicity factor. Transcriptional regulation by AC2 appears to be mediated through interaction with a plant specific DNA binding protein, PEAPOD2 (PPD2), that specifically binds to sequences known to mediate activation of the CP promoter of Cabbage leaf curl virus (CaLCuV) and Tomato golden mosaic virus (TGMV). Suppression of both basal and innate immune responses by AC2 in plants is mediated through inactivation of SnRK1.2, an Arabidopsis SNF1 related protein kinase, and adenosine kinase (ADK). An indirect promoter targeting strategy, via AC2-host dsDNA binding protein interactions, and inactivation of SnRK1.2-mediated defense responses could provide the opportunity for geminiviruses to alter host gene expression and in turn, reprogram the host to support virus infection. The goal of this study was to identify changes in the transcriptome of Arabidopsis induced by the transcription activation function of AC2 and the inactivation of ...

Multan Institute of Cardiology (MIC) is the original name of Chaudhry Pervaiz Elahi Institute of Cardiology. It is located in Multan city in Pakistan. It was established by Chaudhry Pervaiz Elahi former chief minister of Punjab province of Pakistan in 2006. The project of establishing a state of the art tertiary care center for cardiac patients went through various ups and downs in its early days. It was the desire of millions of people living in south Punjab yet was delayed by bureaucracy. In early 2003, Ch Pervaiz Elahi, the honorable Chief Minister of Punjab, took it the center as one of his top priority development projects. The seriousness of his resolve manifested itself when he appointed Col. (Ret) Prof M A Cheema as the Project Director of MIC. Prof. M A Cheema is one of the pioneers of cardiac surgery in Pakistan and had previously established Cardiac Surgery in the Mayo Hospital and Punjab Institute of Cardiology Lahore.

AM948961) from Nawab Shah, Pakistan (Fig. 2).. Defective (df) DNAs are often associated with the geminiviral diseases, which are derived from a partial deletion of viral genomes (Patil and Dasgupta, 2006). These defective molecules have nonanucloetide sequence, which suggests that these df molecules are trans-replicated by the helper virus, resulting in reduction of the viral symptoms, thus referred as defective interfering molecules (Patil and Dasgupta, 2006). Reduction in disease symptoms is either due to initiation of host RNAi mechanism (Bach and Jeske, 2014) or by the competition of df molecules with the helper virus for the cellular resources (Stanley et al., 1990). Along with the full-length begomovirus, two defective begomoviruses were also cloned from the sample. Complete sequencing of defective begomoviruses, having nonanucloetide sequence revealed DNA molecules of half and a quarter of the full-length begomovirus, 1459 and 714 nt respectively. The sequences are available in the ...

O receptor LRR-RLK (Leucine-rich repeat receptor-like kinase), designado NIK1 (NSP-interacting kinases), está envolvido na resposta imunológica em plantas contra Germinivirus. NIK1 foi inicialmente descrito por interagir com a proteína viral NSP (nuclear shuttle protein), proteína que participa do transporte de DNA viral do núcleo para o citoplasma de células infectadas. Com alta similaridade estrutural a NIK1, BAK1 (Brassinosteroid Insensitive Associated Kinase1), também conhecida como SERK3 (Somatic Embryogenesis Receptor Kinase3), é um receptor LRR-RLK de membrana que desempenha um duplo papel em vias de sinalização, podendo atuar como um coreceptor de BRI1 na presença de BR ou mediar respostas de defesa contra patógenos. Na via de crescimento desencadeada por brassinosteróides (BRs), BAK1 interage com BRI1 (Brassinosteroid-insensitive1) na membrana plasmática e ativa a função de cinase desta proteína. Recentemente, através de dados de RNA-seq, foi demonstrado que ...
