Abstract
Protein-protein interactions (PPI) are vital in regulating the biological and physiological functions in a given cell or organism. Proteomics, in conjunction with bioinformatic tools, represents the study involving the characterization of the protein content of the genome of a given biological system. Like PPI, an interaction between either coding or noncoding RNA and a complex set of host proteins protein plays an essential role in gene expression at translational, posttranscriptional, and epigenetic level. Although a wide range of techniques such as shotgun proteomics, MuDPIT, etc. are available for characterizing PII, those for characterizing RNA-protein interactions are infancy. Given the significance of the long noncoding RNAs (lnc-RNA) in plant biology, it is imperative to isolate and characterize the functionality of the host proteome interacting with RNA. In this context, riboproteomics approach becomes a valuable tool to study these interactions. Here, using a noncoding plant pathogenic satellite-RNA (Sat-RNA) of Cucumber mosaic virus (CMV) as an RNA source, we describe a stepwise protocol for identifying the host proteome interacting specifically with the Sat-RNA. This protocol streamlines steps starting from in vitro transcription of RNA, preparation of RNA affinity column, preparation of cell lysate from Nicotiana benthamiana leaves infected with the Sat-RNA followed by the Co-IP and preparation of samples for LC-MS/MS. We believe this approach is applicable to a wide range of RNAs of any nature associated with eukaryotic and prokaryotic organisms.

Abstract
Tomato (Solanum lycopersicum L.) originated in South America and was brought to Europe by the Spaniards in the sixteenth century following their colonization of Mexico. From Europe, tomato was introduced to North America in the eighteenth century. Tomato plants show a wide climatic tolerance and are grown in both tropical and temperate regions around the world. The climatic conditions in the Mediterranean basin favor tomato cultivation, where it is traditionally produced as an open-field plant. However, viral diseases are responsible for heavy yield losses and are one of the reasons that tomato production has shifted to greenhouses. The major tomato viruses endemic to the Mediterranean basin are described in this chapter. These viruses include Tomato yellow leaf curl virus, Tomato torrado virus, Tomato spotted wilt virus, Tomato infectious chlorosis virus, Tomato chlorosis virus, Pepino mosaic virus, and a few minor viruses as well.

Abstract
Cucumber mosaic virus (CMV) associated with D satellite RNA (satRNA) causes lethal systemic necrosis (LSN) in tomato (Solanum lycopersicum), which involves programmed cell death. No resistance to this disease has been found in tomato. We obtained a line of wild tomato, S. habrochaitis, with a homogeneous non-lethal response (NLR) to the infection. This line of S. habrochaitis was crossed with tomato to generate F1 plants that survived the infection with NLR, indicating that NLR is a dominant trait. The NLR trait was successfully passed on to the next generation. The phenotype and genotype segregation was analyzed in the first backcross population. The analyses indicate that the NLR trait is determined by quantitative trait loci (QTL). Major QTL associated with the NLR trait were mapped to chromosomes 5 and 12. Results from Northern blot and in situ hybridization analyses revealed that the F1 and S. habrochaitis plants accumulated minus-strand satRNA more slowly than tomato, and fewer vascular cells were infected. In addition, D satRNA-induced LSN in tomato is correlated with higher accumulation of the minus-strand satRNA compared with the accumulation of the minus strand of a non-necrogenic mutant D satRNA.

Abstract
Virus-resistant transgenic plants (VRTPs) hold the promise of enormous benefit for agriculture. However, over the past ten years, questions concerning the potential ecological impact of VRTPs have been raised. In some cases, detailed study of the mode of action of the resistance gene has made it possible to eliminate the source of potential risk, notably the possible effects of heterologous encapsidation on the transmission of viruses by their vectors. In other cases, the means of eliminating likely sources of risk have not yet been developed. When such residual risk still exists, the potential risks associated with the VRTP must be compared with those associated with nontransgenic plants so that risk assessment can fully play its role as part of an overall analysis of the advantages and disadvantages of practicable solutions to the problem solved by the VRTP.

Abstract
Field trials of transgenic tomato plants expressing an ameliorative satellite RNA of cucumber mosaic virus (CMV) were conducted to test the efficacy of satellite-transgenic technology to protect against CMV infection. Three transgenic tomato lines derived from two susceptible genotypes were evaluated over two growing seasons for viral symptoms and titers, satellite RNA expression, and fruit yield. Satellite-transgenic lines exhibited mild or no CMV symptoms and low viral titers relative to nontransformed plants. A significant negative correlation between satellite RNA levels and disease severity was evident in transgenic lines. Total marketable yield of CMV-infected satellite-transgenic lines was 40 to 84% greater than that of CMV-infected parent lines. Importantly, yield of CMV-infected satellite-transgenic lines did not differ significantly from mock-inoculated parent lines. Risk assessment results demonstrated low levels of satellite RNA transmission within the test site and no evidence of satellite RNA-induced damage on surrounding plants.

Abstract
During 1992, a multivirus epidemic reduced tomato production by as much as 25% in the major tomato-growing region of Alabama. Estimated yield losses of 100% resulted from the epidemic in over 250 ha in two counties of North Alabama. Cucumber mosaic cucumovirus (CMV), alone or in combination with potato potyvirus Y (PVY) and/or tobacco etch potyvirus (TEV), was responsible for the crop failure. CMV was detected alone or in combination with PVY and/or TEV in over 70% of the samples tested and was present in 90% of the fields surveyed. In 1993, 21 tomato fields were monitored weekly from transplanting through harvest for CMV, PVY, TEV, tobacco mosaic tobamovirus, and tomato spotted wilt tospovirus. All 5 viruses were detected, with CMV occurring most frequently. Incidence of CMV at the 61% level or higher was found in 16 of the 21 fields surveyed. Tomatoes transplanted in April and May were least effected and had relatively low virus incidence until late in their development. Tomatoes transplanted in June and July were infected at an earlier age, had the highest virus incidence, were the most severely affected, and suffered the greatest loss in yield. In 1994,Aphis gossypii, the cotton aphid, was the most common virus vector found during an aphid monitoring/virus spread study. Populations of A. gossypii peaked in late June, immediately preceding a period of rapid CMV incidence and spread.

Abstract
Structural studies of plant viral RNA molecules have been based on in vitro chemical and enzymatic modification. That approach, along with mutational analysis, has proven valuable in predicting structural models for some plant viruses such as tobacco mosaic tobamovirus and brome mosaic bromovirus. However, in planta conditions may be dramatically different from those found in vitro. In this study we analyzed the structure of cucumber mosaic cucumovirus satellite RNA (sat RNA) strain D4 in vivo and compared it to the structures found in vitro and in purified virions. Following a methodology developed to determine the structure of 18S rRNA within intact plant tissues, different patterns of adenosine and cytosine modification were found for D4-sat RNA molecules in vivo, in vitro, and in virions. This chemical probing procedure identifies adenosine and cytosine residues located in unpaired regions of the RNA molecules. Methylation data, a genetic algorithm in the STAR RNA folding program, and sequence alignment comparisons of 78 satellite CMV RNA sequences were used to identify several helical regions located at the 5' and 3' ends of the RNA molecule. Data from previous mutational and sequence comparison studies between satellite RNA strains inducing necrosis in tomato plants and those strains not inducing necrosis allowed us to identify one helix and two tetraloop regions correlating with the necrogenicity syndrome.

Abstract
The evolutionary dynamics of 22 variants of cucumber mosaic virus satellite RNA (CMV satRNA) isolated in Italy during virus epidemics from 1988 to 1993 were investigated on the basis of their primary structure and biological properties. Most of the variants were amplified from total nucleic acid preparations extracted from field-infected plants, thus representing wild isolates of CMV satRNA. Eleven variants were associated with subgroup II CMV strains, 10 with subgroup I and 1 with a mixed infection by both strains. When inoculated onto tomato seedlings, the variants induced the phenotype (necrogenic or ameliorative) predicted by their nucleotide sequence. Phylogenetic relationships between the satRNA variants were determined using the stationary Markov model, a stochastic model for evolution. For each satRNA, the Markov analysis gave a good correlation between position in the phylogenetic tree and biological properties. The variants with ameliorative and necrogenic phenotypes in tomato followed two different evolutionary dynamics in nature. Tfn-satRNA, a 390-nt-long molecule, followed a third type of evolutionary dynamic far apart from that of the shorter satRNA molecules (i.e., those in the 334- to 340-nt-length class). Average values of the mean constant rate of nucleotide substitutions/site (Ksubs/site) indicated that in nature the variants tend to keep their heterogeneity unchanged from one epidemic episode to the other, even if the outbreaks occur in places very far from each other. This seems to be in agreement with the proposed maintenance of a functional molecular structure as a constraint to CMV satRNA evolution.

Abstract
The effect of temperature on the response of tomato (Lycopersicon esculentum Mill. cv. Rutgers) to infections with the necrogenic cucumber mosaic virus (CMV) satellite D-CARNA 5 was investigated with each of four CMV strains D, 1, Y and S functioning as helper virus. At 24 degrees C lethal necrosis was observed in all infections. However, at 32 degrees C the response varied from total absence or reduction of necrosis with some strains to accelerated lethal necrosis with others. The total lack of necrotic response with CMV-S and the aggravated necrosis with CMV-Y at the higher temperature both turned out to be independent of the coinfecting satellite, and rather to correlate with the changing rate of viral RNA accumulation in tomato, which probably was responsible for the changes in pathogenic response. However, when CMV-D was helper virus, satellite accumulation decreased, while with CMV-1 it increased, respectively, while viral RNA accumulations were not seriously affected. Although these profound effects of temperature seem to link the necrotic response of tomato to the competitive replication dynamics of the infecting virus/satellite combination in the case of CMV-D/D-CARNA 5, temperature effects at other levels of disease induction probably play an important role as well.

Abstract
In tomato, the disease-modulating effects of a cucumber mosaic virus (CMV) satellite isolate from Belgium, here designated T-CARNA-5 (CARNA-5 = CMV-associated RNA-5), were found to be different depending on the supporting helper virus strain. With two CMV strains, T-CARNA-5 induced lethal necrosis, but with a third strain from Ixora spp. (CMV-Ix), aggravated stunting was observed. However, the primary structure of the T-CARNA-5 contained within virus isolated from tobacco or tomato infected with each of these three CMV strains, conformed to the conserved sequence profile of CARNA-5 isolates which are necrogenic in tomato. Dilution endpoint bioassay of T-CARNA-5 established a direct cause-effect relationship between it and tomato necrosis or stunting, depending on the helper virus. Total nucleic acid extracts taken at different times from tomato plants infected with the above CMV strains and T- or S-CARNA-5 (used as non-necrogenic control) showed viral RNA, ssCARNA-5 and dsCARNA-5 to be present in significant amounts, but in sometimes dissimilar proportions depending on the combination; except in CMV-Ix/S-CARNA-5 infection where neither ss-nor dsCARNA-5 was found. The experiments established that CARNA-5 biological expression studies in CMV-infected tomato have to take into account the helper virus satellite replication support function, which may be a primary codeterminant of quantitative or qualitative differences in the symptom modulation observed.

Abstract
Tomato plants transformed with a single copy of a tomato necrosis causing satellite RNA of cucumber mosaic virus (CMV) express the satellite sequence, but the plants show no disease symptoms and have a normal appearance. Upon challenge infection of the F1 progeny with a CMV strain free of any detectable encapsidated satellite the plants accumulated single and double-stranded forms of satellite RNA and developed lethal necrosis.
