“…In addition, Beta vulgaris , a nonhost for PRSV‐W, failed to become infected. These results indicate that the bottle gourd mosaic virus isolated from Nasik and other regions is a potyvirus closely related to PRSV‐W, and distinct from the virus previously reported by Verma et al . (2004).…”

Zucchini yellow mosaic virus — incidence and sources of virus infection in field-grown cucumbers and pumpkins in the Spreewald, Germany

et al. 2006

In a survey in field-grown cucumber (Cucumis sativus L.) of the Spreewald cultivation area, Germany, from 2001 to 2004, infection with zucchini yellow mosaic virus (ZYMV), watermelon mosaic virus (WMV), cucumber mosaic virus (CMV) and cucumber green mottle mosaic virus (CGMMV) were recorded. ZYMV was of most relevance, owing to its damaging effects and frequency. Pumpkins (Cucurbita pepo L. and Cucurbita maxima Duchesne) were also found to be infected.In glasshouse experiments with 27 fresh and pickle cucumber cultivars frequently cultivated in the area, all cultivars proved (after mechanical inoculation) to be susceptible to ZYMV. ZYMV-infected cucumbers showed leaf chlorosis and mosaic, as well as deformation of leaves and fruits. Mechanical inoculation with ZYMV, in the early developmental stages of cucumber plants, reduced yields by up to 70%. Mixed infection with ZYMV and CMV resulted in synergistic effects, increasing the severity of damage. Fruit and leaf deformation also occurred in cucumber cultivars exhibiting a documented tolerance to CMV.The widespread weeds fat hen (Chenopodium album L.) and hoary alison (Berteroa incana (L.) DC.) were identified as possible sources of natural ZYMV infection in the Spreewald region. ZYMV transmission through seed seems to be of no importance, and possible only if fresh seeds from diseased cucumbers or pumpkins are used (commercially available seed is not contaminated). Uptake of ZYMV through contaminated soil is not a major mode of natural virus transmission, even though it proved possible in baiting experiments. Epidemiologic and economic implications of ZYMV infections of cucumber and pumpkin plants are discussed.In Untersuchungen zum Auftreten von Viren im Freilandanbau von Gurken im Spreewald wurden in den Jahren 2001 bis 2004 Zucchinigelbmosaikvirus (ZYMV), Wassermelonenmosaikvirus (WMV), Gurkenmosaikvirus (CMV) und das Grünscheckungsmosaikvirus der Gurke (CGMMV) nachgewiesen. Von besonderer Bedeutung erwies sich ZYMV im Untersuchungszeitraum durch sein häufiges Auftreten und die großen Schäden. Das Virus war sowohl in Gurken (Cucumis sativus L.) als auch in Kürbissen (Cucurbita pepo L. und Cucurbita maxima Duchesne) nachzuweisen.Versuche mittels mechanischer Inokulation ergaben für alle 27 geprüften Gurkensorten eine Anfälligkeit gegenüber ZYMV. Die Blätter ZYMV-infizierter Pflanzen zeigten Chlorosen und Mosaik, die Früchte waren deformiert. Pflanzen, die in frühen Entwicklungsstadien durch mechanische Inokulation infiziert wurden, reagierten mit Ertragsdepressionen von bis zu 70 Prozent. Bemerkenswert ist, dass eine Mischinfektion von ZYMV und CMV sichtbare Schäden an Sorten verursacht, welche als tolerant gegenüber CMV beschrieben werden.Auf der Suche nach möglichen Infektionsquellen von ZYMV in der Region Spreewald wurden 23 verschiedene Unkrautarten getestet. Natürliche Infektionen mit dem Virus wurden in Weißem Gänsefuß (Chenopodium album L.) und Graukresse (Berteroa incana (L.) DC) gefunden. Eine Übertragung von ZYMV durch kontaminiertes Saatgut wurde bis...

“…In northern India, bottle gourd is cultivated during summer-rainy seasons under hot and humid conditions. Several viruses, like Cucumber mosaic virus [36] Cucumber green mottle mosaic virus [23] Papaya ring spot virus-W [19], Watermelon mosaic virus [1] and Zucchini yellow mosaic virus [38] are known to affect bottle gourd cultivation in India. During the last two decades, begomoviruses have emerged as a severe constraint in cultivation of cucurbits in India [35].…”

Chlorotic Curly Stunt: A Severe Begomovirus Disease of Bottle Gourd in Northern India

et al. 2010

View full text Add to dashboard Cite

Bottle gourd (Lagenaria siceraria) an important vegetable crop in India was observed to be affected by a chlorotic curly stunt disease (CCSD) during [2003][2004][2005][2006] in the vegetable growing areas of Delhi and adjoining state of Haryana. The affected plants are severely stunted and bear very small chlorotic and mildly curled leaves. Incidence of the disease varied from 4.7 to 36%. The disease could be easily transmitted by whitefly, Bemisia tabaci but not by sap. The causal virus was found to be a Begomovirus on the basis of whitefly transmission and sequence identity of putative coat protein (CP) and replication initiator protein (Rep) genes. The virus was transmitted to Cucumis sativus, Luffa acutangula, L. cylndrica, Lycopersicon esculentum, Nicotiana tabacum and Praecitrullus fistulosus but not to Citrullus lunatus, Cucumis melo, Cucurbita moschata and Vigna unguiculata. The N-terminal 60 amino acids of CP of the virus had 100% sequence identity with all the isolates of Tomato leaf curl New Delhi virus (ToLCNDV) and two isolates of Squash leaf curl China virus (SLCCV). The full length amino acid sequence of the CP and Rep genes had 100% similarity with ToLCNDVSvr and -Luffa isolates. The phylogenetic analysis showed that the virus associated with CCSD of bottle gourd belongs to ToLCNDV cluster of the begomoviruses. This is the first record of emergence of a Begomovirus associated severe disease in bottle gourd in India.
