Design of highly specific cytotoxins by using trans-splicing ribozymes. (1/288)

We have designed ribozymes based on a self-splicing group I intron that can trans-splice exon sequences into a chosen RNA target to create a functional chimeric mRNA and provide a highly specific trigger for gene expression. We have targeted ribozymes against the coat protein mRNA of a widespread plant pathogen, cucumber mosaic virus. The ribozymes were designed to trans-splice the coding sequence of the diphtheria toxin A chain in frame with the viral initiation codon of the target sequence. Diphtheria toxin A chain catalyzes the ADP ribosylation of elongation factor 2 and can cause the cessation of protein translation. In a Saccharomyces cerevisiae model system, ribozyme expression was shown to specifically inhibit the growth of cells expressing the virus mRNA. A point mutation at the target splice site alleviated this ribozyme-mediated toxicity. Increasing the extent of base pairing between the ribozyme and target dramatically increased specific expression of the cytotoxin and reduced illegitimate toxicity in vivo. Trans-splicing ribozymes may provide a new class of agents for engineering virus resistance and therapeutic cytotoxins.  (+info)

Strong host resistance targeted against a viral suppressor of the plant gene silencing defence mechanism. (2/288)

The 2b protein encoded by cucumber mosaic cucumovirus (Cmv2b) acts as an important virulence determinant by suppressing post-transcriptional gene silencing (PTGS), a natural plant defence mechanism against viruses. We report here that the tomato aspermy cucumovirus 2b protein (Tav2b), when expressed from the unrelated tobacco mosaic tobamovirus (TMV) RNA genome, activates strong host resistance responses to TMV in tobacco which are typical of the gene-for-gene disease resistance mechanism. Domain swapping between Cmv2b, which does not elicit these responses, and Tav2b, revealed functional domains in Tav2b critical for triggering virus resistance and hypersensitive cell death. Furthermore, substitution of two amino acids from Tav2b by those found at the same positions in Cmv2b, Lys21-->Val and Arg28-->Ser, abolished the ability to induce hypersensitive cell death and virus resistance. However, in Nicotiana benthamiana, a species related to tobacco, Tav2b functions as a virulence determinant and suppresses PTGS. Thus, a viral suppressor of the host gene silencing defence mechanism is the target of another independent host resistance mechanism. Our results provide new insights into the complex molecular strategies employed by viruses and their hosts for defence, counter-defence and counter counter-defence.  (+info)

Rearrangements in the 5' nontranslated region and phylogenetic analyses of cucumber mosaic virus RNA 3 indicate radial evolution of three subgroups. (3/288)

Cucumber mosaic virus (CMV) has been divided into two subgroups based on serological data, peptide mapping of the coat protein, nucleic acid hybridization, and nucleotide sequence similarity. Analyses of a number of recently isolated strains suggest a further division of the subgroup I strains. Alignment of the 5' nontranslated regions of RNA 3 for 26 strains of CMV suggests the division of CMV into subgroups IA, IB, and II and suggests that rearrangements, deletions, and insertions in this region may have been the precursors of the subsequent radiation of each subgroup. Phylogeny analyses of CMV using the coat protein open reading frame of 53 strains strongly support the further division of subgroup I into IA and IB. In addition, strains within each subgroup radiate from a single point of origin, indicating that they have evolved from a single common ancestor for each subgroup.  (+info)

Host-specific cell-to-cell and long-distance movements of cucumber mosaic virus are facilitated by the movement protein of groundnut rosette virus. (4/288)

The cucumovirus, cucumber mosaic virus (CMV), requires both the 3a movement protein (MP) and the capsid protein (CP) for cell-to-cell movement. Replacement of the MP of CMV with the MP of the umbravirus, groundnut rosette virus (GRV), which does not encode a CP, resulted in a hybrid virus, CMV(ORF4), which could move cell to cell in Nicotiana tabacum and long distance in N. benthamiana. After replacement of the CMV CP in CMV(ORF4) with the gene encoding the green fluorescent protein (GFP), the hybrid virus, CMV(ORF4.GFP), expressing both the GRV MP and the GFP, could move cell to cell but not systemically in either Nicotiana species. Immunoelectron microscopic analysis of cells infected by the hybrid viruses showed different cellular barriers in the vasculature preventing long-distance movement of CMV(ORF4) in N. tabacum and CMV(ORF4.GFP) in N. benthamiana. Thus the GRV MP, which shows limited sequence similarity to the CMV MP, was able to support CP-independent cell-to-cell movement of the hybrid virus, but CP was still required for long-distance movement and entry of particular vascular cells required functions encoded by different proteins.  (+info)

Recombination between genomic RNAs of two cucumoviruses under conditions of minimal selection pressure. (5/288)

Recombination is considered to play a key role in RNA virus evolution; however, little is known about its occurrence under natural conditions. We inoculated tobacco plants with wild-type strains of two closely related cucumovirus species: cucumber mosaic virus (CMV) and tomato aspermy virus (TAV). RNA from the inoculated leaves of doubly-infected plants was tested for the presence of recombination events in an 0.8-kb central portion of the viral RNA3. Using a sensitive and specific RT-PCR procedure, we amplified recombinant segments of RNA3 in 3 of 82 tobacco plants infected with both viruses. In each plant in which recombinant segments were amplified, several different crossover sites were observed, all of which were located within a short stretch of high sequence similarity. Two plants had both CMV-TAV and TAV-CMV recombinants. In all cases, precise homologous recombination had occurred. To the best of our knowledge, this is the first report of interspecific recombination between wild-type plant RNA viruses under conditions of minimal selection pressure in favor of the recombinants.  (+info)

Resistance of Capsicum annuum 'Avelar' to pepper mottle potyvirus and alleviation of this resistance by co-infection with cucumber mosaic cucumovirus are associated with virus movement. (6/288)

Capsicum annuum cv. Avelar plants resist systemic infection by the Florida isolate of pepper mottle potyvirus (PepMoV-FL). Immuno-tissue blot analysis for detection of PepMoV-FL infection in selected stem segments revealed that virus moved down the stem in external phloem, and, over time, accumulated to detectable levels throughout stem sections (appearing to accumulate in external and internal phloem) taken from below the inoculated leaf. At 21 days post-inoculation, PepMoV-FL was detected in stem segments one or two internodes above the inoculated leaf; however, no virus was observed in internal phloem in stem segments beyond these internodes. In contrast to these observations, PepMoV-FL was detected in the internal phloem of all internodes of the stem located above the inoculated leaf, with subsequent movement into non-inoculated leaves, in Avelar plants co-infected with PepMoV-FL and cucumber mosaic cucumovirus (CMV-KM). No apparent enhancement of PepMoV-FL accumulation occurred in protoplasts inoculated with PepMoV-FL alone versus a mixed inoculum of PepMoV-FL and CMV-KM. These findings confirm earlier observations that potyvirus movement up the stem of Capsicum species occurs via internal phloem. It is also shown that PepMoV-FL does not accumulate to detectable levels in internal phloem in the stem of Avelar plants, thereby limiting its movement to within the inoculated leaf and lower portions of the stem; however, co-infection of Avelar plants with CMV-KM alleviates this restricted movement, allowing PepMoV-FL to invade young tissues systemically.  (+info)

A single-stranded loop in the 5' untranslated region of cucumber mosaic virus RNA 4 contributes to competitive translational activity. (7/288)

The 5' untranslated region (UTR) of cucumber mosaic virus (CMV) RNA 4 confers a highly competitive translational advantage on a heterologous luciferase open reading frame. Here we investigated whether secondary structure in the 5' UTR contributes to this translational advantage. Stabilization of the 5' UTR RNA secondary structure inhibited competitive translational activity. Alteration of a potential single-stranded loop to a stem by substitution mutations greatly inhibited the competitive translational activity. Tobacco plants infected with wild type virus showed a 2.5-fold higher accumulation of maximal coat protein than did plants infected with a loop-mutant virus. Amplification of viral RNA in these plants could not explain the difference in accumulation of coat protein. Phylogenetic comparison showed that potential single-stranded loops of 12-23 nucleotides in length exist widely in subgroups of CMV.  (+info)

Isolation of a putative tobacco host factor interacting with cucumber mosaic virus-encoded 2b protein by yeast two-hybrid screening. (8/288)

The cucumber mosaic virus (CMV)-encoded 2b protein has been implicated to play a role in long distance movement of the virus through the plant's transport system. It is unknown, however, how it mediates virus movement and whether any intrinsic components of plant cells also participate in this process. To isolate a host factor that interacts with 2b, the yeast two-hybrid system was used. First, it was found that the 2b protein per se could function as a transcriptional activator in yeast. However, its two carboxyl terminal deletion mutants, 2bdelta98 and 2bdelta95, which lacked 12 and 15 amino acids from the carboxyl terminus respectively, showed complete absence of transcriptional activation in yeast. A tobacco cDNA library expressing the GAL4 activation domain fusion proteins was screened using 2bdelta98 as a bait. A clone named 2bip (2b-interacting protein) was isolated whose translation product apparently interacted with 2b. Consistent with this observation, bacterially expressed GST-2bip fusion protein bound tightly to 2bdelta95 and 2bdelta98 polypeptides in vitro, as well as to the unmodified 2b protein. Nucleotide sequencing and database searches revealed that the amino acid sequence deduced from it was similar to a prokaryotic LytB protein and an unknown protein of Arabidopsis. DNA and RNA gel blot analyses showed that 2bip-related sequences were present in the tobacco genome and that transcripts corresponding to 2bip were expressed constitutively in various plant organs and in response to CMV infection. These results suggest 2bip as a novel host factor that is capable of interacting with CMV2b.  (+info)

Cucumber Mosaic Virus Identification and Control. CMV actually effects over 1200 plant species including cucumbers and related squash, melons and curcubits, tomatoes, Peppers and related plants and nearly all commonly grown vegetable and ornamental garden plants. In fact, it has the widest host range of any known plant virus.
We examined the correlation of the amino acid at position 129 in the coat protein (CP) of cucumber mosaic virus (CMV) with the phenotype of the viral pathology in tobacco by using CP mutants in which several amino acid substitutions had been introduced. An exchange between Ser129 in CMV-Y, a chlorosis-inducing strain, and Pro129 of CMV-O, a green-mosaic-inducing strain, reciprocally altered the phenotypes of those virus strains on tobacco. Replacement of either Ser129 in CMV-Y or Pro129 in CMV-O with a Leu, as is found in a chlorosis-inducing strain, CMV-M, resulted in veinal necrosis. Furthermore, we created mutants that have a Phe or a Gly at position 129. Two Phe129 mutants induced necrotic lesions on the inoculated leaves, and a Gly129 mutant induced green mosaic symptoms. In inoculated protoplasts, the mutant viruses and the wild-type virus all replicated RNA well, and accumulated CP; however, infection with the Leu129 and Phe129 mutants yielded few virions. The Phe129 mutants lacked the capacity

A woodiness disease of passionfruit was described by Cobb (1901) but as both passionfruit woodiness and cucumber mosaic viruses may cause woody fruit and leaf mosaic (Taylor, 1959), the authenticity of records prior to that of McKnight (1953) is in doubt. However, passionfruit woodiness virus was rare in P. edulis in Queensland in 1927 and widespread in 1932 (Simmonds, 1959) suggesting that it was introduced into that State about 1927. Its absence from cool, temperate areas of Australia and the rare occurrence of cucumber mosaic virus in Queensland suggest that ecological factors influence the distribution of both viruses. Experimentally, a mixed infection by the two viruses in P. edulis causes a very severe disease (Taylor, 1959), but naturally occurring mixed infections are not always so virulent. To differentiate the two viruses it is best to use the electron microscope; the filamentous particles of passionfruit woodiness virus are usually readily found in the sap of infected plants. The ...

Zucchini squash (Cucurbita pepo) is a systemic host for most strains of the cucumovirus Cucumber mosaic virus (CMV), although the long-distance movement of the M strain of CMV (M-CMV) is inhibited in some cultivars. However, co-infection of zucchini plants with M-CMV and the potyvirus Zucchini yellow mosaic virus strain A (ZYMV-A) allowed M-CMV to move systemically, as demonstrated by tissue-print analysis. These doubly infected plants exhibited severe synergism in pathology. Infection of zucchini squash by M-CMV and an attenuated strain of ZYMV (ZYMV-AG) showed a milder synergy in pathology, in which ZYMV-AG also facilitated the long-distance movement of M-CMV similar to that promoted by ZYMV-A. Variation in the extent of synergy in pathology by the two strains of ZYMV did not correlate with differences in levels of accumulation of either virus. Thus, the extent of synergy in pathology is at least in part independent of the resistance-neutralizing function of the potyvirus ...
To determine the structural requirements for cucumber mosaic virus (CMV) satellites to elicit lethal tomato necrosis, three satellite variants D, S and Y were used in the construction and cloning of chimeric cDNAs. D and S are necrogenic and non-necrogenic prototype variants, respectively, and Y possesses the 3′ conserved necrosis-determining region but does not cause lethal tomato necrosis. Its 5′ half harbours an insertion/deletion region that results in a molecule about 30 nucleotides longer than other variants. Tomato bioassays were conducted with RNA transcripts of all six chimeric combinations of the 5′ and 3′ halves of the three satellite variants divided by a common restriction site, as well as with a mutated chimera. None of the chimeras containing the 5′ half of Y induced lethal necrosis in tomato even when their 3′ halves were that of the D variant with the conserved necrogenic element. Chimeras with the 3′ half of Y elicited only partial or restricted necrosis which was much
The Cucumber mosaic virus (CMV)-encoded 2b protein (Cmv2b) is a nuclear protein that suppresses transgene RNA silencing in Nicotiana benthamiana. Cmv2b is an important virulence determinant but nonessential for systemic spread in N. glutinosa, in contrast to its indispensable role for systemic infections in cucumber. Here, we report that Cmv2b became essential for systemic infections in older N. glutinosa plants or in young seedlings pre-treated with salicylic acid (SA). Expression of Cmv2b from the genome of either CMV or Tobacco mosaic virus significantly reduced the inhibitory effect of SA on virus accumulation in inoculated leaves and systemic leaves. A close correlation is demonstrated between Cmv2b expression and a reduced SA-dependent induction of the alternative oxidase gene, a component of the recently proposed SA-regulated antiviral defense. These results collectively reveal a novel activity of Cmv2b in the inhibition of SA-mediated virus resistance. We used a N. tabacum line ...
Cucumber mosaic virus (CMV) is a serious pathogen of many economically important crops. In Western Australia (WA), CMV is a serious disease of narrow-leafed lupin, Lupinus angustifolius, which is the main grain legume crop. There is no known natural resistance genes to CMV have been identified .in narrow-leafed lupin germplasm that can be transferred to new cultivars using classical breeding techniques. The aim of this project was to develop a series of molecular resistance constructs and to apply them to produce pathogen-derived resistance to CMV in narrow-leafed lupin. A total of nine different CMV resistance gene constructs were developed. Eight constructs were based on the movement protein (MP), coat protein (CP) and replicase (Rep) genes of the WA subgroup II CMV-LY isolate originally obtained from infected narrow-leafed lupin, and one was based on the CP gene of a WA subgroup I CMV isolate from banana.. The gene constructs were cloned into the plant binary vectors pYR2 and pART27/7 driven ...
The cucumber mosaic virus (CMV) 2b protein not only inhibits anti-viral RNA silencing but also quenches transcriptional responses of plant genes to jasmonic acid, a key signalling molecule in defence against insects. This suggested that it might affect interactions between infected plants and aphids, insects that transmit CMV. We found that infection of tobacco with a 2b gene deletion mutant (CMVD2b) induced strong resistance to aphids (Myzus persicae) while CMV infection fostered aphid survival. Using electrical penetration graph methodology we found that higher proportions of aphids showed sustained phloem ingestion on CMV-infected plants than on CMVD2b-infected or mock-inoculated plants although this did not increase the rate of growth of individual aphids. This indicates that while CMV infection or certain viral gene products might elicit aphid resistance, the 2b protein normally counteracts this during a wild-type CMV infection. Our findings suggest that the 2b protein could indirectly ...

Satellite RNAs Cucumber mosaic virus (an epiphytotic of lethal necrotic disease among tomato plants in France in 1972). This was unusual because of the severity and atypical nature of the symptoms associated with infections of tomato plants (See description of cucumber mosaic in prior text). Enhanced response of tomatoes to this disease were associated with host used for virus propagation; virus grown in tobacco or tomato yielded an enhanced necrotic response, those propagated in cucurbit hosts yielded a reduce necrotic response. RNA extractions of necrotic tomato plants revealed the presence of variable amounts of a small RNA species in addition to the expected three genomic and one subgenomic RNAs. This 5th RNA species was designated CARNA 5 (i.e., CMV-associated RNA 5 or CMV satRNA), a satellite RNA. When CARNA 5 is present with CMV, symptoms of the disease are enhanced in tomato plants, while in tabasco pepper the presence of CARNA 5 tends to attenuate the disease symptoms caused by CMV. ...

When CARNA 5 is present with CMV, symptoms of the disease are enhanced in tomato plants, while in tabasco pepper the presence of CARNA 5 tends to attenuate the disease symptoms caused by CMV. ...

To investigate the extent of the 3 end repair in a satellite RNA of Cucumber mosaic virus (CMV) strain Q (Q(sat)) by a heterologous Tomato aspermy virus (TAV), a set of biologically active agrotransformants corresponding to the three genomic RNAs of TAV was developed. Analysis of Nicotiana benthamiana plants agroinfiltrated with TAV and either wild type or each of the six 3 deletion mutants of Q(sat) revealed that (i) heterologous replicase failed to generate Q(sat) multimers, a hallmark feature of homologous replicase dependent replication of Qsat; (ii) manifestation of severe symptom phenotypes and progeny analysis suggested that heterologous replicase was competent to repair Q(sat) deletion mutants lacking up to 313 nucleotides (nt) but not beyond and (iii) comparative in silico analysis indicated that the 3 secondary structural features of the repaired Q(sat) progeny from heterologous vs homologous driven replicases are remarkably very similar. The significance of these observations is discussed

Cucumber mosaic virus (CMV) is a plant pathogenic virus in the genus Cucumovirus, family Bromoviridae. It has the potential and reputation of having the widest host range of any known plant virus including monocotyledons and dicotyledons, herbaceous plants, shrubs and trees. CMV is one of the major diseases in Capsicum annum (chilli).

Using a transient plant system, it was previously found that the suppression of Cucumber mosaic virus (CMV) 2b protein relies on its double-strand (ds) RNA binding capacity, but it is independent of its interaction with ARGONAUTE (AGO) proteins. Thus, the biological meaning of the 2b-AGO interaction in the context of virus infection remains elusive. In this study, we created infectious clones of CMV mutants that expressed the 2b functional domains of dsRNA or AGO binding and tested the effect of these CMV mutants on viral pathogenicity. We found that the mutant CMV2b(1-76) expressing the 2b dsRNA-binding domain exhibited the same virulence as wild-type CMV in infection with either wild-type Arabidopsis or rdr1/6 plants with RDR1- and RDR6-deficient mutations. However, remarkably reduced viral RNA levels and increased virus (v)siRNAs were detected in CMV2b(1-76)-infected Arabidopsis in comparison to CMV infection, which demonstrated that the 2b(1-76) deleted AGO-binding domain failed to suppress the RDR1
fr] Actuellement, dans lest de la Chine, le contrôle des pucerons repose sur lutilisation systématique dinsecticides de synthèse. Lanalyse de la structure socio-économique des ménages ruraux de la province du Shandong a permis de mettre en avant la méconnaissance des agriculteurs vis-à-vis des effets néfastes de ces molécules chimiques sur lenvironnement et sur la santé humaine. Cette conclusion conduit à rechercher de nouvelles méthodes alternatives efficientes pour les producteurs chinois. Dans ce contexte de lutte biologique contre les pucerons et leur transmission virale (Potato virus Y (PVY), Cucumber mosaic virus (CMV) et Potato Leaf Roll Virus (PLRV)), trois substances sémiochimiques à savoir, l(E)-β-farnésène, le cis-3-hexényl acétate, lextrait dail et une culture intercalaire de pois ont été expériméntées séparément à laide de pièges jaunes dans des cultures de pommes de terre et de courgettes.

Figure 8 shows the overall quaternary structure derived for the AMV particles. The VRU strain differs only slightly in amino acid sequence from that of AMV 425 (Fig. , 1979). Nevertheless, the VRU strain is also capable of forming the stacked lattice, reflecting the polymorphism of the assembled protein. The proposed hexagonal surface lattice possesses twofold symmetry axes andd quasi-three- and quasi-sixfold axes. Two types of dimer interactions are in evidence, one producing a flat face (a dihedral angle of 180° between trimers) while the other utilizes a dihedral angel of about 140°, similar to that observed between trimers of an icosahedron. However, there is no serological relationship between AMV and TSV or CVV or CLRV and the tryptic peptide maps of TSV and AMV protein show no similarity (van Vloten-Doting, 1975). Capsid proteins from the Bromo- and Cucumovirus groups will not activate Ilarvirus RNA. Recently, Roosien and van Vloten-Doting (1983) reported a coat protein mutant of AMV ...
I think I used about 12 cucumbers but you can pickle any amount, just adjust the quantity of spiced vinegar you make. The night before, peel and slice all your cucumbers and place in a large bowl. Pour over about a tablespoon of salt. Dont worry, you wont eat the salt. If you dont drawn the fluid from the cucumbers it dilutes the vinegar too much in the jars. Mix the cucumbers around with your hands, making sure the salt is well distributed, put a clean tea towel over the top of the bowl and leave it overnight. The following morning there will be a lot of fluid in the cucumber bowl. Pour it all into a colander and let the salty water go down the drain. Run clean cold water from the tap over the cucumbers to make sure all the salt is removed. Leave the cucumber in the colander for about an hour to drain ...

Gentian (Gentiana sp.) is an important perennial flower in Japan. In terms of cut flower cultivation area size it occupies 2nd to 3rd place. Cucumber mosaic virus (CMV), broad bean wilt virus (BBWV), tobacco rattle virus and clover yellow vein virus have been reported to infect gentians. We have analyzed gentian plants collected from the largest production area in Japan, Ashiro-cho in the Iwate prefecture, and found that most plants with severe virus symptoms were infected either by CMV alone or by both CMV and BBWV. The association of CMV with severe symptomatolgy was also confirmed in greenhouse experiments in which CMV and BBWV isolates obtained from symptomatic gentian plants were inoculated to gentian seedlings. CMV induced severe symptoms, while BBWV did not cause any. Dual inoculation of CMV and BBWV slightly aggravated symptoms in comparison with those caused by CMV alone. These results suggested that CMV is the most destructive virus in gentian. In greenhouse experiments three satellite ...
It was recently discovered that the widespread plant pathogen cucumber mosaic virus elevates the release of host volatiles, or odorous chemicals, that attract vectors. Researchers measured the rates of aphid population growth on and emigration from healthy and infected plants. It was discovered that aphids were initially more attracted to the infected plants than to the healthy plants. However, the aphids dispersed rapidly from the diseased hosts after feeding. This form of transmission is known as non-persistent transmission because rather than long-term feeding and colonizing on the plants (persistent), the vectors are repelled by the inferior quality and move on to other plants (non-persistent). This type of transmission is advantageous for CMV as it facilitates easy transmission from one host to another ...
This project applies biotechnology to effectively mitigate the impact of pests and pathogens on priority floral crops and develops systems that can be manipulated to preserve select hardwood tree taxa for future genetic engineering applications. Genetic engineering of floral crops for pest and pathogen resistance contributes to sustainable production. There has been little research done on migratory nematodes such as Pratylenchus, and this project addresses the use of transgenes that may be effective in controlling Pratylenchus. Viruses are always a problem for propagated plants, particularly flower bulb crops that are propagated from the same bulb for many years. This project determines if an RNAi approach is effective for control of Cucumber mosaic virus (CMV), an economically important virus that affects numerous crops. In vitro manipulation of plants through genetic engineering allows for rapid clonal propagation, ploidy level manipulation, and preservation of germplasm and cryopreservation. ...

Slicing cucumbers are best served fresh and raw, but they can also be sautéed, fried, or even mixed in drinks. Cucumbers contain most of their nutrients in their seeds and their skin. It is advised, from a nutritional standpoint, to eat cucumbers with both. However, cucumbers have wax coatings on their skin. Organically grown cucumbers have non-synthetic waxes where conventionally grown cucumbers may have synthetic waxes and pesticides. If you choose to eat the skin, buy organic cucumbers to eliminate the risk of synthetic wax consumption. If buying organic is not an option, then thoroughly wash each cucumber with a brush or simply remove the skin before eating.. ...
when they are about 6-8 inches long. Cucumbers intended for dill pickles can be harvested at 4 to 6 inches long and pickles at as little as 2 inches. The larger burpless cucumbers can be up to 10 inches long and some types are even larger, although if they are left on the vine too long, they can become bitter or yellow. The highest quality cucumber is uniformly green, firm and crisp.. At peak harvesting time, you should be picking cucumbers every couple of days. Pay attention to what the plant is telling you. Check plants daily, ensuring no fruit is laying on the ground, rotting and that the tendrils and leaves are growing where you want them. Training cucumber vines and picking them as they ripen will ensure longer and healthy vegetable production.. As cucumbers are over 90% water, they must be stored tightly in plastic wrap and properly refrigerated. They will keep (on average) 7-10 days when properly stored and delicious in dozens of recipes and applications.. We certainly have enjoyed ...

Envelope glycoprotein that forms spikes at the surface of virion envelope. Essential for the initial attachment to heparan sulfate moieties of the host cell surface proteoglycans. Involved in fusion of viral and cellular membranes leading to virus entry into the host cell. Following initial binding to its host receptors, membrane fusion is mediated by the fusion machinery composed at least of gB and the heterodimer gH/gL. May be involved in the fusion between the virion envelope and the outer nuclear membrane during virion egress.
