Cucumber mosaic virus on Black Pepper in Yogyakarta and Bangka BelitungPepper  (Piper  nigrum)  is  spice  crop  which  has  been  cultivated  a  long  time  ago  in  Indonesia. Stunting is one of disease on pepper caused by cucumber mosaic virus (CMV). The research aimed to diagnose the biological, morphological and nucleaic acid characters of CMV on pepper in Yogyakarta and Bangka Belitung. CMV infection on pepper in both area (Putat dan Kleben village, Yogyakarta and Air Buluh village, Bangka Belitung) showed typical symptoms such as mosaic, narrow leaves and stunting. The disease incidence and disease severity of stunting disease are varies. The virus able to transmitted by cutting, grafting and mechanically on Nicotiana tabacum and Chenopodium amaranticolor. However, it was unable to transmitted mechanically on pepper and by Aphis gossypii. The virus particles were isometric with diameter size 28-30 nm. RT-PCR using coat protein partial gene primer successfully amplified a DNA with size ± 500 bp from all three samples. The homology of nucleotide between three isolates was 98-97%, while the highest homology of those three strains CMV  from Yogyakarta and Bangka Belitung was 98% against strains from China in Brassica chinensis. Three strains CMV from pepper were in the same group, and separated from CMV pepper lines from Indonesia and other CMV isolates.

Black pepper (Piper nigrum L.) is  an important estate crops in Indonesia. Some pathogens that have been known to infect black pepper plants include fungi, nematodes and viruses. The stunting disease on black pepper plants was caused by Cucumber mosaic virus (CMV). Molecular detection using RT-PCR method showed that the samples were positively infected by CMV which were amplified by specific primers CMV 111 with bands of 111 bp in size. This virus can be carried by vegetative propagation material of plants. Many control strategies against this virus have been investigated, especially inducing plant resistance with chitosan. Chitosan is a natural biopolymer that play an important role in reducing disease incidence and severity and stimulate plant growth. The aim of this study was to figure out the inhibiting  ability of chitosan solution against infection of stunting virus on black pepper seedlings through spraying applications. Chitosan treatments were prepared in concentrations of 0.5%, 0.75%, and 1%. The result showed that application of chitosan at all concentrations affected the decrease of disease incidence and intensity and improved plant growth with insignificant different amongst all treatments but significantly different with control. The highest decrease in incidence was found at 0.75% of chitosan concentration (26.37), while the highest decrease of intensity was expressed at 1% of chitosan (37.62). Application of chitosan also significantly affected to all parameters of plant growth either plant height or leaf diameter. Application of 1% of chitosan increased the percentage of plant growth rather than other treatments, with the increase of plant height 58.12 % and leaf diameter 54.74 %. IntisariLada (Piper nigrum L.) merupakan salah satu tanaman perkebunan penting di Indonesia. Beberapa patogen telah diketahui menginfeksi tanaman lada di antaranya jamur, nematoda, dan virus. Penyakit kerdil pada tanaman lada disebabkan oleh Cucumber mosaic virus (CMV).

Local Lesions

During surveys of Dichondra repens (kidneyweed, family Convolvulaceae) turfs in public gardens of the Franco-Italian Riviera from 1993 to 2003, leaf mosaic and yellow ringspot symptoms have been observed in Antibes, Menton, Nice, and Vallauris (France) and San Remo and La Mortola (Italy). Isolates from these six locations and from two locations in China (Shanghai and Kunming) have revealed the presence of Cucumber mosaic virus (CMV) based on the behavior of a range of manually inoculated plants (1), the observation of 30 nm isometric particles in semipurified extracts of inoculated Nicotiana tabacum ‘Xanthi’ plants with the electron microscope, and positive reactions in double antibody sandwich (DAS)-ELISAs with specific polyclonal antibodies. All isolates were shown to belong to group II of CMV isolates (3) by double-immunodiffusion analysis. CMV was previously identified in D. repens in California in 1972 (4). Following isolation from local lesions on Vigna unguiculata and multiplication in ‘Xanthi’ tobacco plants, two of the isolates were used to inoculate seedlings of D. repens manually or by Aphis gossypii aphids. Two months later, all inoculated plants showed symptoms similar to those previously observed and were positive in DAS-ELISA. In 2000, a D. repens sample collected in Antibes showing similar symptoms as above, induced necrotic local lesions in inoculated ‘Xanthi’ plants in 48 h, followed by systemic mosaic symptoms typical of CMV, therefore revealing the presence of a second virus. That virus was separated from CMV in apical, noninoculated leaves of Chenopodium quinoa and then used to inoculate a range of test plants. It was infectious in most plants of the families Solanaceae (including Cyphomandra betacea) and Brassicaceae, together with in Chenopodium amaranticolor, C. quinoa, Claytonia perfoliata, Convolvulus spp. ‘Belle de jour’, Digitalis purpurea, Gomphrena globosa, Ocimum basilicum, Plantago lanceolata, and Valerianella olitoria. It induced asymptomatic systemic infections in D. repens. Numerous, rod-shaped, 300 nm long particles were observed in sap extracts of infected plants with the electron microscope, suggesting the presence of a tobamovirus. A set of primers polyvalent for tobamoviruses (2) allowed the amplification of a DNA product of approximately 800 bp through reverse transcription-PCR performed with total RNA extracts from inoculated ‘Xanthi’ plants. The DNA product was cloned and sequenced (GenBank Accession No. EU927306) revealing that the virus belonged to a tobamovirus lineage including Ribgrass mosaic virus and viruses infecting cruciferous plants (Turnip vein-clearing virus [TVCV] and Youcai mosaic virus) and was closest to TVCV (95% amino acid identity; GenBank Accession No. NC_001873). To our knowledge, this is the first report of TVCV in D. repens. References: (1) L. Cardin et al. Plant Dis. 87:200, 2003. (2) A. Gibbs et al. J. Virol. Methods 74:67, 1998. (3) M. J. Roossinck. J.

Entomological aspects of the epidemiology of cucumber mosaic virus (CMV) were studied in Michigan. Myzus persicae (Sulzer) and Aphis gossypii Glover were efficient vectors of CMV between various hosts in the laboratory. Macrosiphum euphorbiae (Thomas) transmitted CMV between cucumber and Echinocystis lobata (Michx.) T. & G. Myzocallis asclepiadis (Monell) was shown to be a new vector of CMV between Asclepias syriaca L. Neither Melanoplus differentialis (Thomas) nor Acalymma vittata (Fabricius) transmitted the virus in limited trials.There was a small proportion of cucumber plants infected early in July, when alate M. persicae were present. In August the incidence of infection rose rapidly after a period of activity of alate A. gossypii. Alate aphids were trapped in yellow water pans situated in and around cucumbers. Seven known vectors of CMV were caught.

Resistance Evaluation of Chillipepper Cultivars for Cucumber Mosaic Virus and Chilli Veinal Mottle Virus.  The use of resistance culivars is an important strategy for management of virus infection in chillipepper. A research was undergone to study the effect of single and mix infection of CMV and ChiVMV on the disease incidence and on the growth and yield of nine chillipepper cultivars, i.e. Cilibangi 4, Cilibangi 5, Cilibangi 6, Helem, Jatilaba, Tit Bulat, Tit Segitiga, Tit Super and Tampar. Mechanical inoculation was conducted to transmit the virus. Infection of the virus was then confirmed with DAS-ELISA.  In general, inoculated chillipepper cultivars developed similar symptoms, i.e. mosaic type for CMV and mottle type for ChiVMV.  More severe symptom was not always observed from mix infection of CMV and ChiVMV. Disease incidence occurred in the range of 16.67 – 86.0% and this caused 18.3 – 98.6% yield loss.  Based on symptom expression, ELISA result, and reduction on yield, it can be concluded that all chillipepper cultivars used in this study could not hold up the virus infection. However, several cultivars showed tolerance response :  Jatilaba, Tit Super, and Tampar for CMV; Cilibangi 4 for ChiVMV; Tit Super for mix infection; and Cilibangi 5 for CMV, ChiVMV, and mix infection.  Further evaluation and investigation involving different chillipepper cultivars should be conducted.

Satellite RNAs (satRNAs) are associated with Cucumber mosaic virus (CMV) in tomato, most often causing severe epidemics of necrotic plants, and not associated with specific host symptoms. Laboratory studies on virus transmission by the aphid vector Aphis gossypii were performed to better understand the dynamics of field populations of CMV. The presence of satRNAs correlated with lower concentrations of virus in infected plants and with a decrease in the efficiency of transmission from satRNA-infected plants. Both the concentration of virus in CMV-infected tomato and the efficiency of transmission varied more extensively with nonnecrogenic satRNAs than with necrogenic satRNAs. A negative effect of satRNAs on virus accumulation can account, in part, for a decrease in the field transmission and recovery of CMV + satRNAs. Aphids behaved differently and probed less readily on plants infected with CMV + necrogenic satRNAs compared with plants containing non-necrogenic satRNAs. Aphid-mediated satRNA-free CMV infections were observed in test plants when aphids were fed on source plants containing CMV + nonnecrogenic satRNA; no comparable satRNA-free test plants occurred when aphids were fed on source plants containing necrogenic satRNAs. These results indicate that factors associated with transmission can be a determinant in the evolution of natural populations of CMV and its satRNA.

Screening Method for Chilli Veinal Mottle Virus  (Chi VMV) and Cucumber Mosaic Virus  (CMV) Resistance in Chillipepper.  ChiVMV and CMV have been reported as the causal agents of main diseases in chillipepper in Indonesia and other Asian countries.  Mix infection of this two viruses was commonly occurred in the field, causing severe disease .  The use of resistance varieties has been proposed for dealing with the yield losses causing by  the viruses.  Breeding program is undergoing for development of chillipepper varieties resistant to ChiVMV and CMV.  Methodology for routine screening activity of chillipepper for resistance to both ChiVMV and CMV needs to be established. This research was conducted in Cikabayan Glass House and Plant Virology Laboratory, Plant Protection Department, Bogor Agricultural University from May 2006 to June 2007. Aim of the research was to develop screening method for simultaneous infection by the two viruses, ChiVMV and CMV.  Inoculation of ChiVMV and CMV was done by single inoculation or repetitive inoculation methods.  In both methods, ChiVMV and CMV were inoculated in different sequences, either ChiVMV or CMV first.  The result showed that incubation period was shorter when CMV was inoculated in advance both in single and repetitive inoculation method.  Mosaic, mottle and malformation type symptom was observed in infected plants. Based on disease incidence, infection of ChiVMV was higher compared to CMV in repetitive inoculation as well as in single inoculation.  Repetitive inoculation methods with virus sequence ChiVMV-CMV-ChiVMV-CMV  was selected for resistance evaluation of chillipepper genotypes.

The chili pepper (Capsicum spp. L.) is a vegetable of economic importance that has been affected worldwide by the cucumber mosaic virus (CMV), a pathogen that causes a devastating disease in this crop. The aim of this research was the detection and characterization of CMV in chili pepper crops in Valle del Cauca, Colombia. Leaves of three chili pepper varieties (tabasco, cayenne and habanero) with viral symptoms were collected in four municipalities of Valle del Cauca. Total RNA was purified and a fragment of capsid protein (CP) from CMV was amplified by RT‑PCR. Then, it was sequenced and bioinformatically analyzed, and from these sequences, specific primers were designed. From 71 chili pepper samples collected in Palmira, Yumbo, Vijes and Yotoco, 37 were positive for CMV (52.1%). The CMV chili pepper sequence analysis showed that they had their highest identity (98.5%) with a CMV isolated from bananas in Ecuador. Specific primers designed for CMV chili pepper showed greater sensitivity for detecting this virus (64.7% vs. 52.1%). The CMV chili pepper CP analysis indicated that it could be transmitted by the species Aphis gossypii. This r the first time, the molecular characterization of CMV in three chili pepper varieties.
