“…Each of these viruses is transmitted by eriophyid mites, has 4 to 7 RNA species, a virus-specific 32-kDa protein, MBBs of similar size and morphology, and is mechanically transmitted in sap extracts but not in purified preparations (2,13,19,30,34). However, no serological relationship was detected between these two viruses.…”

“…This is a very significant finding because several decades of work on eriophyid-mite transmitted agents of unknown aetiology have suggested that these agents are not transmitted mechanically and have a restricted host range. HPV is reported to be transmitted mechanically in sap to moist maize seed by vascular puncture (Loui & Seifers, 1998;Forster et al, 2001), but this disease agent seems restricted in host range to species in the Graminae (Forster et al, 2001). By contrast, the mite-transmitted agent of fig mosaic was transmitted from its natural host, fig (Ficus carica: Moracea), to periwinkle (Caranthus roseus: Vinceae) by its mite vector, Aceria ficus, and the cells of the infected periwinkle plants contained MBBs indistinguishable from those present in infected fig (Credi, 1998).…”

Pigeonpea sterility mosaic virus (PPSMV) is transmitted by the eriophyid mite, Aceria cajani, and is very closely associated with sterility mosaic disease (SMD) of pigeonpea (Cajanus cajan) in the Indian subcontinent. Antiserum produced to purified PPSMV preparations detected a virus-specific 32 kDa protein in sap of SMD-affected pigeonpea plants by ELISA and Western blotting. PPSMV was transmitted mechanically in sap of SMD-affected pigeonpea leaves to Nicotiana benthamiana. Ultrastructural studies of symptom-bearing leaves of two pigeonpea cultivars, (ICP8863 and ICP2376) and N. benthamiana infected with PPSMV, detected quasi-spherical, membrane bound bodies (MBBs) of c. 100-150 nm and amorphous electron-dense material (EDM). These structures were distributed singly or in groups, in the cytoplasm of all cells, except those in conductive tissues. Fibrous inclusions (FIs), composed of randomly dispersed fibrils with electron lucent areas, were present in the cytoplasm of palisade cells and rarely in mesophyll cells of the two pigeonpea cultivars but were not detected in infected N. benthamiana plants. In the PPSMV-infected pigeonpea cultivars and N. benthamiana, immuno-gold labelling, using antiserum to PPSMV, specifically labelled the MBBs and associated EDM, but not the FIs. The MBBs and associated inclusions are similar in appearance to those reported for plants infected with the eriophyid mite-transmitted High Plains virus and the agents of unidentified aetiology associated with rose rosette, fig mosaic, thistle mosaic, wheat spot chlorosis and yellow ringspot of budwood. The nature of these different inclusions is discussed.

“…In North America, WSMV is widespread being present in the main wheat production areas of the USA (Arkansas, California, Georgia, Idaho, Kansas, Kentucky, Missouri, Montana, Nebraska, North Dakota, Ohio, South Dakota, Texas, Utah) (CABI International 2002;Forster et al 2001;Harvey et al 1995a, b;Townsend and Johnson 1996) and in Canada (Alberta, Ottawa and Ontario) (Harvey et al 1995a, b;Seifers et al 1998). It was also detected in Mexico during the last decade (Sánchez-Sánchez et al 2001).…”

Wheat curl mite, Aceria tosichella, and transmitted viruses: an expanding pest complex affecting cereal crops

et al. 2012

View full text Add to dashboard Cite

The wheat curl mite (WCM), Aceria tosichella, and the plant viruses it transmits represent an invasive mite-virus complex that has affected cereal crops worldwide. The main damage caused by WCM comes from its ability to transmit and spread multiple damaging viruses to cereal crops, with Wheat streak mosaic virus (WSMV) and Wheat mosaic virus (WMoV) being the most important. Although WCM and transmitted viruses have been of concern to cereal growers and researchers for at least six decades, they continue to represent a challenge. In older affected areas, for example in North America, this mite-virus complex still has significant economic impact. In Australia and South America, where this problem has only emerged in the last decade, it represents a new threat to winter cereal production. The difficulties encountered in making progress towards managing WCM and its transmitted viruses stem from the complexity of the pathosystem. The most effective methods for minimizing losses from WCM transmitted viruses in cereal crops have previously focused on cultural and plant resistance methods. This paper brings together information on biological and ecological aspects of WCM, including its taxonomic status, occurrence, host plant range, damage symptoms and economic impact. Information about the main viruses transmitted by WCM is also included and the epidemiological relationships involved in this vectored complex of viruses are also addressed. Management strategies that have been directed at this mite-virus complex are presented, including plant resistance, its history, difficulties and advances. Current research perspectives to address this invasive mite-virus complex and minimize cereal crop losses worldwide are also discussed.
