The virions are non-enveloped spherical particles containing a single protein. Multiple strains are named after the places where outbreaks have occurred.
Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands. (Kendrew, Encyclopedia of Molecular Biology, 1994, p503)
Use of restriction endonucleases to analyze and generate a physical map of genomes, genes, or other segments of DNA.
An acute viral infection in humans involving the respiratory tract. It is marked by inflammation of the NASAL MUCOSA; the PHARYNX; and conjunctiva, and by headache and severe, often generalized, myalgia.
An individual that contains cell populations derived from different zygotes.
A collection of single-stranded RNA viruses scattered across the Bunyaviridae, Flaviviridae, and Togaviridae families whose common property is the ability to induce encephalitic conditions in infected hosts.
A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).

Physical and functional heterogeneity in TYMV RNA: evidence for the existence of an independent messenger coding for coat protein. (1/667)

Turnip yellow mosaic virus RNA can be separated into two distinct components of 2 times 10(6) and 300 000 daltons molecular weight after moderate heat treatment in the presence of SDS or EDTA. The two species cannot have arisen by accidental in vitro degradation of a larger RNA, as they both possess capped 5' ends. Analysis of the newly synthesized proteins resulting from translation of each RNA by a wheat germ extract shows that the 300 000 molecular weight RNA can be translated very efficiently into coat protein. When translated in vitro the longer RNA gave a series of high molecular weight polypeptides but only very small amounts of a polypeptide having about the same mass as the coat protein. Thus our results suggest that the small RNA is the functional messenger for coat protein synthesis in infected cells.  (+info)

Complete sequence and genome properties of Chinese wheat mosaic virus, a new furovirus from China. (2/667)

The complete nucleotide sequence of a virus infecting winter wheat in Shandong province, China has been determined. This was previously thought to be soil-borne wheat mosaic virus but, while the two viruses are related, they are only 75% (RNA1) and 63% (RNA2) identical at the nucleotide level, while the amino acid sequences share from 62% (19 kDa RNA2 product) to 84% (RNA1 replicase) identity. The analysis shows that the Chinese virus should be considered a new member of the genus Furovirus and has been named Chinese wheat mosaic virus (CWMV). A Cys-Gly ... Cys-Gly-X-X-His amino acid pattern was identified in the cysteine-rich protein of CWMV and those of several other plant virus genera, which seems likely to have some functional significance.  (+info)

The sCYMV1 hairpin ribozyme: targeting rules and cleavage of heterologous RNA. (3/667)

The catalytic center of the RNA from the negative strand of the satellite RNA of chicory yellow mottle virus type 1 (sCYMV1) is in the hairpin ribozyme family, has catalytic activity, and cleaves substrates before a preferred GUA sequence. This is different from that of the satellite RNA from the negative strand of tobacco ringspot virus (sTRSV) which prefers a GUC sequence at the site of cleavage. The sCYMV1 hairpin ribozyme has now been developed for cleaving heterologous RNA substrates. When helix 1 was extended from the native 5 bp to 6 bp with a newly added A:U base pair, catalytic activity increased three-fold. The preferred sequence for the substrate loop was the native A*GUA sequence where * is the site of cleavage. When each nucleotide in this sequence was changed to each of the other three nucleotides, catalytic activity decreased 66-100%. RNA targets, containing this A*GUA sequence, were located in both human papillomavirus and HIV-1. Ribozymes were developed which efficiently cleaved these targets in vitro. These results identify a new class of hairpin ribozymes capable of cleaving substrates before a preferred GUA sequence rather than the GUC preferred by the sTRSV hairpin ribozyme. This expands the repertoire of target sites available for gene therapy using the hairpin ribozyme.  (+info)

Rapid generation of genetic heterogeneity in progenies from individual cDNA clones of peach latent mosaic viroid in its natural host. (4/667)

Viroids, small single-stranded circular RNAs endowed with autonomous replication, are unique systems to conduct evolutionary studies of complete RNA genomes. The primary structure of 36 progeny variants of peach latent mosaic viroid (PLMVd), evolved from inoculations of the peach indicator GF-305 with four individual PLMVd cDNAs differing in their pathogenicity, has been determined. Most progeny variants had unique sequences, revealing that the extremely heterogeneous character of PLMVd natural isolates most probably results from the intrinsic ability of this RNA to accumulate changes, rather than from repeated inoculations of the same individual trees under field conditions. The structure of the populations derived from single PLMVd sequences differed according to the observed phenotype. Variant gds6 induced a reproducible symptomatic infection and gave rise to a more uniform progeny that preserves some parental features, whereas variant gds15, which induced a variable phenotype, showed a more complex behaviour, generating two distinct progenies in symptomatic and asymptomatic individual plants. Progenies derived from variants esc10 and Is11, which incited latent infections, followed a similar evolutionary pattern, leading to a population structure consisting of two main groups of variants, one of which was formed by variants closely related to the parental sequence. The evolution rate exhibited by PLMVd, considerably higher than that reported for potato spindle tuber viroid, may contribute to the fluctuating symptomatology of the severe PLMVd natural isolates. However, the polymorphism observed in PLMVd progenies does preserve some structural and functional elements previously proposed for this viroid, supporting the fact that they act as constraints limiting the genetic divergence of PLMVd quasispecies generated de novo.  (+info)

Sequences of European wheat mosaic virus and oat golden stripe virus and genome analysis of the genus furovirus. (5/667)

The complete nucleotide sequences of both RNAs of oat golden stripe virus (OGSV) and a wheat-infecting furovirus isolate from France, previously thought to be soil-borne wheat mosaic virus (SBWMV), have been determined. Both viruses had a similar genomic organisation to SBWMV and Chinese wheat mosaic virus, the two other furoviruses previously sequenced but had <70% nucleotides identical to them. The French isolate has been named European wheat mosaic virus (EWMV). Phylogenetic analyses supported the recognition of these isolates as distinct viruses in the genus Furovirus. Analysis of the coat protein readthrough domain on RNA2 of all furoviruses strongly predicts two mutually compatible conserved transmembrane domains that may be significant for fungus transmission. The second of these regions is eliminated by a deletion in the isolate of OGSV studied. Leaky opal (UGA) stop codons occur on both RNAs of all four furoviruses characterised and, in common with most other leaky opal codons identified in plant viruses, they are followed by a CGG codon.  (+info)

Structural fingerprinting: subgrouping of comoviruses by structural studies of red clover mottle virus to 2.4-A resolution and comparisons with other comoviruses. (6/667)

Red clover mottle virus (RCMV) is a member of the comoviruses, a group of picornavirus-like plant viruses. The X-ray structure of RCMV strain S has been determined and refined to 2.4 A. The overall structure of RCMV is similar to that of two other comoviruses, Cowpea mosaic virus (CPMV) and Bean pod mottle virus (BPMV). The sequence of the coat proteins of RCMV strain O were modeled into the capsid structure of strain S without causing any distortion, confirming the close resemblance between the two strains. By comparing the RCMV structure with that of other comoviruses, a structural fingerprint at the N terminus of the small subunit was identified which allowed subgrouping of comoviruses into CPMV-like and BPMV-like viruses.  (+info)

Quasi-elastic behavior of solutions of viral capsid and RNA at very low shearing stresses. (7/667)

By the application of shearing stresses on the order of 10(-3) dyne cm-2 (10(-2) muN cm-2), via the magnetic viscodensimeter, extremely high relative viscosities (greater than 500) were observed when turnip yellow mosaic virus was degraded in alkali into its capsid and RNA. The solutions, however, possessed a watery consistency at this stage and exhibited a quasi-elastic character by rotor-recoil experiments. The development of this curious behavior was concentration and temperature dependent; it was not seen less than 0.5% nor at 8 degrees, and appeared sooner at 30 degrees than at 20 degrees. The time of appearance was delayed as the pH was lowered; however, the effect was still observed when the pH was as low as 9. Whereas reversibility was demonstrated when the shearing stresses exceeded the elastic resistance [0.17 dyne cm-2 (1.7 muN CM-2)], thorough mixing usually resulted in a normal behavior of the solutions thereafter. Values for the modulus of rigidity at 20 degrees for about 1% virus concentration was less than 2 X 10(-2) dyne cm-2 rad-1 (0.2 muN cm-2 rad-1), which, while extremely small, was reproducible. A porous structure, possibly involving a capsid and RNA complex, is envisioned.  (+info)

A gene cluster encoded by panicum mosaic virus is associated with virus movement. (8/667)

A subgenomic RNA (sgRNA) of about 1500 nucleotides has been detected in millet plants and protoplasts infected with panicum mosaic virus (PMV). This sgRNA expressed p8, p6.6, p15, and the 26-kDa capsid protein (CP) genes during in vitro translation assays, as determined by using mutants inactivated for expression of each open reading frame. Abolishing expression of p8 and p6.6, the two 5'-proximal genes on the sgRNA, did not affect the replication of PMV in millet protoplasts, but obstructed spread in plants. As predicted for a typical cell-to-cell movement protein, p8 localized to the cell wall fraction of PMV-infected millet plants. The introduction of premature stop codons downstream of the PMV p15 start codon (p15*) abolished infectivity in planta, but did not impair replication in protoplasts. However, a delayed systemic infection in millet plants was supported by the p15aug(-) start codon mutant, which may reflect very low levels of expression from a suboptimal start codon context and/or leaky scanning to a second inframe AUG codon to express the C-terminal portion of the 15-kDa protein. PMV CP mutants had little effect on sgRNA accumulation, but were correlated with a reduction of the gRNA and the decreased expression of the 8-kDa protein in protoplasts as well as abolishment of cell-to-cell spread in plants. These results imply that the successful establishment of a PMV systemic infection in millet host plants appears to be dependent on the concerted expression of the p8, p6.6, p15, and CP genes.  (+info)

Southern bean mosaic virus ATCC ® PVAS-298™ Designation: Cowpea [southern bean mosaic virus antiserum] Application: Test animal used: rabbit Host plant from which virus was purified: Vigna unguiculata cv. Plant research
Abstract: The mode of inheritance of resistance to cowpea aphid-borne mosaic virus (CAMV) and southern bean mosaic virus (SBMV) was determined in the following cowpea (Vigna unguiculata s.sp. unguiculata (L) Walp) varieties: A44/2, TVu 222, TVu 612 all resistant to CAMV and TVu 1948, which is resistant to both CAMV and SBMV. Crosses were made between each of the resistant varieties and C20-55, a cowpea variety susceptible to CAMV and SBMV. The parents, FI, F2, B1 and B2 progenies of each cross were raised in the greenhouse and inoculated with the appropriate virus. The results showed that two recessive genes control resistance to CAMV in A44/2, a single dominant gene controls resistance to the same virus in TVu 222, while a single recessive gene was responsible for resistance in each of the varieties TVu 612 and TVu 1948. Results of allelic tests among the F1 and F2 progenies of crosses among A44/2, TVu 612, and TVu 222 indicated that each of them possesses different genes for resistance to ...
Biomolecules are increasingly attractive templates for the synthesis of functional nanomaterials. Chief among them are the plant Tobacco mosaic virus (TMV) and Barley stripe mosaic virus (BSMV) due to their high aspect ratio, narrow size distribution,
Summary Barley tissue with an acute systemic infection of barley stripe mosaic virus contained a large amount of unencapsidated virus RNA which was stable in extracts made in ribosome isolation buffer. The virus RNA in ribosome preparations sedimented in a broad band at 80S to 100S in sucrose gradients, which is less than the virion sedimentation rate of 180S to 200S. A protein of apparent M r 60000, which sedimented with the virus RNA, was present in ribosome extracts from infected plants but absent from those from uninfected plants. The protein is probably a virus protein because its apparent molecular weight varied slightly with the strain of virus. The structure containing the M r 60000 protein did not sediment in sucrose gradients in a compact zone as would be expected for a particle of uniform size. The M r 60000 protein was present at a concentration equal to or slightly higher (up to 400 µg/g leaf tissue) than the unencapsidated virus RNA (up to 300 µg/g leaf tissue). Sedimentation results
Only one of four isolates (C4) of barley stripe mosaic virus (BSMV) was transmitted (airbrush method of inoculation) from barley (Hordeum vulgare Black Hulless ) to wild oats (Avena fatua). Initially, the proportion of inoculated wild oat plants systemically infected by isolate C4 was low, and in some plants only localized infections developed in inoculated leaves. However, when isolate C4 was subsequently transferred from infected to healthy wild oats, the proportion of inoculated plants infected was high and the infection was invariably systemic. These observations and several additional lines of evidence indicated that this pattern of transmission was due to strain selection during systemic passage of isolate C4 through wild oats. Complete separation of strains comprising this isolate, however, apparently did not occur until three successive passages of the virus through wild oats. After this, the selected strain from barley systemically infected almost all wild oat plants that were ...

Virus induced gene silencing (VIGS) is a technology that has been used primarily to target the virus genome in infected plants. However, if the virus genome carries inserts derived from the host plant, the system could be employed to target the mRNAs corresponding to the host gene. Barley Stripe Mosaic Virus (BSMV), a disease of various cereals including barley and wheat, has been one of the successfully used viral RNA silencing tools in monocotyledonous plants for the last decade. In this study, we investigated several factors that play a significant role in VIGS. We tested the efficiency of silencing two genes simultaneously using the BSMV-induced gene silencing (IGS) system in detail. We found that two genes could be silenced simultaneously using BSMV-IGS. However, the silencing efficiency was found to be influenced by several factors including stability of the insert, temperature, and the accumulation of small viral RNAs from BSMV. The effect of these factors on VIGS system has been ...

PY - 1985/10/30. Y1 - 1985/10/30. N2 - In the differential scanning calorimetry (DSC) scans of turnip yellow mosaic virus (TYMV) or its capsid a single endotherm was observed. The endotherm was attributed to disruption of the virion or capsid structure with accompanying protein denaturation. At pH 4.5 the thermal stabilities of the TYMV virion and capsid were similar. With increasing pH, the capsid stability increased while the virion stability decreased. At neutral pH the capsid disrupted at 83.5°, and the virion disrupted at 69°. Our results suggest that packaging of viral RNA in the TYMV capsid imparts instability. The pHmid for disruption of the TYMV capsid is 5.7, which is in the pKa range ...
Plant Dicer-like (DCL) enzymes exhibit a GC-preference during anti-viral post-transcriptional gene silencing (PTGS), delivering an evolutionary selection pressure resulting in plant viruses with GC-poor genomes. However, some viruses, e.g. Turnip Yellow Mosaic Virus (TYMV, genus Tymovirus) have GC-rich genomes, raising the question as to whether or not DCL derived selection pressure affects these viruses. In this study we analyzed the virus-derived small interfering RNAs from TYMV-infected leaves of Brassica juncea showed that the TYMV population accumulated a mutational bias with AU replacing GC (GC-AU), demonstrating PTGS pressure. Interestingly, at the highly polymorphic sites the GC-AU bias was no longer observed. This suggests the presence of an unknown mechanism preventing mutational drift of the viral population and maintaining viral genome stability, despite the host PTGS pressure.. ...

Cauliflower Mosaic Virus is classified as an icosahedral (20 sided) virus. This is because of the icosahedral shape of the capsid that surrounds the viral genome. This shape gives the virus 20 symmetrical triangular faces. This symmetry allows for synthesis efficiency by having the same small number of proteins being produced from a small number genes and from short chromosome sequences. This allows the largest and most complex capsid to be formed from the least amount of resources making it more efficient than a non-symmetrical capsid (Slonczewski). The structure of cauliflower mosaic virus is approximately 52 nanometers in diameter and is surrounded by 420 capsid proteins arranged in triangulation T=7 (P, Ashwathi). In addition to capsid proteins, caulimoviruses are also surrounded by virus associated proteins (Caulimovirus.). These proteins are responsible for assisting in the binding of the virus to DNA on its c-terminal end (InterPro.). The efficiency of the icosahedral structure allows ...

American Society of Sugarbeet Technologists. Interpretive Summary: Technical Abstract: Exposure to a prolonged cold period during winter is necessary for flowering in the next spring in many biennial plants - a process termed vernalization. We have described BvFL1, a vernalization gene in sugar beet (Beta vulgaris), which is a repressor of flowering that is downregulated in response to cold. This gene is a homolog to the MADS-bx gene FLOWRING LOCUS C(FLC)found in Arabidopsis thaliana. Flowering time is a trait of critical agronomic importance, and an assessment of function at this key regulatory locus may present an opportunity to study (and control) flowering time as a tool in applied plant breeding efforts. Virus induced gene silencing constructs were engineered into a Barley stripe mosaic virus (BSMV) vector for use in blocking ...
Cauliflower mosaic virus has a very important function in biotechnology. It is because of its efficient promoter that is used to produce cloned genes, that it can be used to create transgenic plants that can take use of this efficiency. That is why now, 10% of cruciferous vegetables have a CaMV infection[16]. In order to do this, genes can only be inserted in the minor coding regions or regions not necessary for virus production which include open reading frame II and open reading frame VII. If done correctly, the production of progeny viruses will not be affected. A use of this is to insert a dihydroxyl folatereductase gene so that the infected plant will be resistant to methotrexate which otherwise is very toxic to plants[15]. Producing transgenic plants is done in order to gain benefits such as higher yield, resistance, quality and efficiency which would be hugely impactful to farmers who have been plagued by mosaic viruses and had to throw away a large percentage of their crop[11]. There are ...
Being aware of the different types of Mosaic Viruses can help to keep your plants thriving and virus-free. Plant has 2 leaves, big leaf was the original propagation leaf,small leaf has just emerged showing good variegation. Unfortunately, some of these signs can be due to many other factors such as insufficient watering, high humidity or too much sunlight. We have included some of the most commonly asked questions in regards to this infection that will hopefully answer any further concerns you may have. Interestingly the virus can also be latent in plants meaning that you cannot see any symptoms yet but the plant is already a host and is affected.

Salah satu penyakit yang menyerang tanaman tebu adalah penyakit mosaik yang disebabkan oleh Sugarcane Mosaic Virus (SCMV) (Koesmihartono,2009). Kehadiran virus ini dapat menghambat fotosintesis, merusak tanaman dan menekan tingkat produktifitas tanaman tebu hingga 0.2%-50% tergantung dari seberapa berat infeksi virus dan ketahanan varietas terhadap Sugarcane Mosaic Virus (Duriat,1979). Salah satu upaya dalam mencegah penyebaran virus tersebut terutama di lapang adalah dengan cara deteksi dini melalui uji serologi. Untuk dapat melakukan uji serologi sebagai upaya uji deteksi dini perlu diproduksi protein rekombinan salah satu caranya adalah melalui kloning (perbanyakan dalam sel bakteri) cDNA yang menyandikan protein mantel dan melakukan konstruksi ke dalam vektor ekspresi. Protein rekombinan yang dapat digunakan untuk memproduksi antigen dalam pembuatan antibodi. Tahapan yang dilakukan adalah mengisolasi materi genetik yang ada pada SCMV beerupa RNA dan mengubahnya menjadi cDNA untuk kemudian ...

Viruses spread through a plant in two steps. The first step is from cell to cell within the inoculated leaf. However, as soon as the virus has reached a cell bordering the vascular system of the plant, it can also spread via the vascular system throughout the entire plant. To spread from cell to cell, the virus needs to enlarge existing channels connecting neighbouring cells by building up a tunnel to transport the virus from one cell into the other. This is because the natural channels connecting the cells are too narrow for the virus to pass through ...
The present investigation was conducted to see the effect of Soybean Mosaic Virus (SMV) infection on carbohydrate content in nodules of soybean. Observation made on the carbohydrate (reducing sugar, non-reducing sugar and starch) content of nodules in soybean mosaic virus infected soybean indicated the reduction of all the contents in comparison to nodules in the healthy plants. Reducing sugar ranged from 2.0 to 3.39 mg g-1 dry weight in healthy and in diseased it ranged from 1.86 to 3.00 mg g-1 dry weight and in non reducing sugar ranged from 1.4 to 2.75 mg g-1 dry weight and in healthy and in diseased it ranged from 1.3 to 2.45 mg g-1 dry weight. The results were significant in the case of non-reducing sugar. The reducing and non-reducing sugars were estimated by the colorimetric method. The alcohol extract was clarified and residue left on the filter paper was returned to the extracting flask, dried at 65°C and preserved for starch analysis ...
During research carried out in the Netherlands, Marilia Santos Silva discovered that some tobacco plants die if a virus infects them, whereas others survive.
Extracts of barley leaves infected with bromegrass mosaic virus (BrMV) incorporated radioactivity into RNA when incubated with [3H]UTP in the presence of actinomycin D (Semal & Kummert, 1970). The radioactive product thus obtained was partly resistant to pancreatic RNase in × 2:SSC (0.15 m-NaCl, 0.015 m-sodium citrate, pH 7.0:SSC) but was entirely hydrolysed by this enzyme in × 0.05:SSC (Semal, 1970). A sequential synthesis of double- and single-stranded RNA was obtained under certain experimental conditions (Semal & Kummert, 1971). The present results identify the radioactive product associated with duplex RNA as a segment of BrMV-RNA. Cell-free extracts of the second leaf of barley seedlings, whose first leaf had been inoculated 3 days earlier with BrMV, were used to prepare the crude virus-induced RNA polymerase fraction. This fraction was incubated for 3½ min. with tritiated UTP (1 to 2 c/mm - The Radiochemical Centre, Amersham, Buckinghamshire, England), 10-3 m-EDTA, 20 µg./ml. of
In this study a new real-time PCR assay for the detection of figwort mosaic virus (FMV) DNA is described. This assay targets a 113-bp-long sequence of the FMV open reading frame Vll, a non-conserved coding region among the caulimoviruses. Detection of FMV DNA is useful to complement screening for the FMV 34S promoter (P-FMV), a genetic element present in several genetically modified (GM) plants. T ...
