“…Subsequently, other members infecting economic plants were identified and currently, six species are officially recognised (http://www.ictvonline.org/virusTaxonomy.asp?version=2009). In addition to LCCV reported in this study, two more new species Yam chorotic necrotic mosaic virus (Wang et al , ) and Artichoke latent virus (Ciuffo et al , ) were reported during last 2 years. There is a rising importance of the macluraviruses as a taxonomic group and it is necessary to revise the genus Macluravirus .…”

“…The denatured CP of the purified virus showed two bands of about 40 and 35 kDa, of which 40 kDa is the estimated molecular mass of the capsid protein as the lower band is expected due to proteolytic degradation as seen in CdMV (Gonsalves et al , ; Jacob & Usha, ). Contrastingly, in RaLV no degradation but multimerisation of CP was obtained above the 40‐kDa band (Ciuffo et al , ). The deduced aa sequence, however, showed a lower molecular mass of 33.7 kDa.…”

Large cardamom (Amomum subulatum), an important spice crop grown in eastern sub-Himalayan mountains of India, is affected by a viral disease commonly known as 'chirke', which is characterised by light and dark green streaks on the leaf lamina. Although chirke has been known to affect large cardamom for over 50 years, its distribution in large cardamom growing regions and aetiology have remained unaddressed. In this study for the first time, distribution of chirke in the major large cardamom growing regions in India has been determined. North Sikkim and eastern region of Darjeeling hills were endemic region with average disease incidence of 19.2-35%, whereas, Mirik region of Darjeeling hills were free from the disease. Suckers, the commonly used planting material, were the major source for spread of the disease. The virus was sap transmissible to the popular large cardamom cultivars Golsey, Ramsey, Swaney and Varlangey and vectored by Rhopalosiphum maidis and Myzus persicae in a non-persistent manner. Flexuous virus particles measuring 625-650 × 12.5 nm were observed consistently associated with the diseased samples. Polyclonal antiserum to the purified virus showed serological affinity with a macluravirus, cardamom mosaic virus (CdMV) associated with a similar disease known as katte disease of small cardamom (Elettaria cardamomum) occurring in southern India. The 3 terminal genome sequence (1776 nucleotides) of the virus was determined, which revealed a close sequence identity and phylogenetic relationships with the members of the genus Macluravirus. The deduced amino acid sequence of putative coat protein (CP) gene showed maximum similarity of 65.7% with the CdMV. Phylogenetic analysis based on CP and 3 UTR showed that the virus was closer to Alpinia mosaic virus, CdMV and Chinese yam necrotic mosaic virus subclade. The results suggest that the virus associated with the chirke disease of large cardamom is a new species under the genus Macluravirus in the family Potyviridae for which the name large cardamom chirke virus (LCCV) is proposed.

“…Occurrence of virus-like symptoms prompted surveys (107,109,130) along the Italian Riviera, where Ranunculus is cultivated for export. Previously reported viruses and three new potyviruses were identified: ranunculus leaf distortion virus, ranunculus mild mosaic virus, and ranunculus mosaic virus; a new macluravirus, artichoke latent virus (20), was also detected. Ranunculus white mottle virus (RWMV), a new ophiovirus detected in about 30% of ranunculus plants, was also found in anemone (132).…”

Since the 1950s, there have been major changes in the scope, value, and organization of the ornamental plant industry. With fewer individual producers and a strong trend toward consolidation and globalization, increasing quantities of diverse plant genera and species are being shipped internationally. Many more ornamentals are propagated vegetatively instead of by seed, further contributing to disease spread. These factors have led to global movement of pathogens to countries where they were not formerly known. The emergence of some previously undescribed pathogens has been facilitated by high-throughput sequencing, but biological studies are often lacking, so their roles in economic diseases are not yet known. Case studies of diseases in selected ornamentals discuss the factors involved in their spread, control measures to reduce their economic impact, and show some potential effects on agronomic crops. Advances in diagnostic techniques are discussed, and parallels are drawn to the international movement of human diseases. Expected final online publication date for the Annual Review of Phytopathology, Volume 61 is September 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…Ranunculus hybrids, subsequently referred to as ranunculus, are susceptible to infection by several viruses, in most cases found in mixed infection, all associated with economically important diseases (Vaira et al ., ; Garibaldi et al ., ; Turina et al ., ; Ciuffo et al ., ; Restuccia et al ., ). Common viral symptoms on ranunculus are mottling, chlorosis, mosaic, necrosis and deformation on leaves, vein yellowing, stunting of the plant and deformation and colour breaking on flowers.…”

Buttercup (Ranunculus asiaticus, family Ranunculaceae) hybrids are considered a popular and valuable ornamental crop in Europe and are cultivated both for cut flowers and for pot or border plants. In the Liguria region of northern Italy, Ranunculus hybrid cultivation has dramatically increased over recent years and the related sanitary issues regarding virus infection need to be carefully monitored in order to maintain commercial competitiveness. Presently, ELISA is the most used diagnostic tool for virus diagnosis, but if ‘mother plants’ with high economic value are to be tested, more sensitive molecular diagnostic tools are needed, together with efficient protocols for in vitro culture to eradicate viruses. In this study, new RT‐PCR protocols were tested on virus‐infected Ranunculus hybrid plants, indexed for the 13 most important Ranunculus‐infecting viruses. Rapid, uniform and effective procedures for molecular diagnosis were devised in order to promote an easy technology transfer from scientific institutions to laboratories of small and medium private enterprises. Moreover, an in vitro culture procedure was established for this species, which proved to be extremely effective in virus eradication. Advanced technology and sustainable quality production of high economic value plants are keys for future competitiveness in floriculture.
