“…Geographical prevalence and distribution of plant viruses often have a strong bearing to virus-vector relations (Power and Flecker, 2003;Power, 2008) implying that availability vectors transmitting the viruses is a key determinant in high virus incidence (Ng and Falk, 2006;Bragard et al, 2013;Whitfield et al, 2015). All the viruses under the current study are known to be transmitted by aphids (Dodds et al, 1984;Kishaba et al, 1992;Lecoq and Desbiez, 2012), but CMV (Zitter and Murphy, 2009;Jacquemond 2012;Sevik and Balkaya 2015) and ZYMV (Simmons et al, 2011(Simmons et al, , 2013 can also be seed-transmitted in different hosts. A relatively higher number of different aphid species were observed in central than eastern districts (Our unpublished data), and this may partly explain the observed low and high incidences in east and central respectively.…”

“…Aphids of different species transmit CMV, WMV and ZYMV non-persistently, or CABYV persistently (Dodds et al, 1984;Kishaba et al, 1992;Lecoq and Desbiez, 2012), but seed-transmission of ZYMV (Simmons et al, 2011(Simmons et al, , 2013 and CMV (Zitter and Murphy, 2009;Jacquemond, 2012) are also known. The geographical and host range of plant viruses is delimited more by virus-vector than virus-host relations (Power andFlecker, 2003, Power, 2008), which in accordance with its broad vector range makes CMV cosmopolitan infecting over 1200 species in over 100 families of plants worldwide (Zitter and Murphy, 2009;Jacquemond, 2012;Lecoq and Desbiez, 2012).…”

Common impromptu observations between 2010 and 2012 of apparent virus-like disease symptoms in watermelons and pumpkins in Uganda prompted this study. However, there was no recorded evidence of virus infection in these crops anywhere in Uganda or eastern Africa as a region. Thus, 374 and 522 watermelon and pumpkin plants, respectively, growing in 13 fields were surveyed to record virus-like disease symptoms in Uganda's four districts of Mbale and Kamuli (eastern region), Mpigi and Masaka (central region) during August to November 2013, and January to March 2014. Leaf samples were also collected and tested for four viruses known to commonly infect watermelons and pumpkins worldwide. Symptom severity was assessed using a scale of 0 to 5, while virus incidence was determined by serological methods. The four viruses tested were Cucumber mosaic virus (CMV), Watermelon mosaic virus (WMV), Zucchini yellow mosaic virus (ZYMV) and Cucurbit aphid borne-yellows virus (CABYV). In both crops, there was a higher incidence of virus-like diseases in central than in eastern region (P = 0.000). All the four viruses were detected w ith CMV as the most common, followed by WMV, ZYMV, and CABYV. Differences in virus incidences between the districts were not always significant. Single CMV, dual CMV+WMV and triple CMV+WMV+ZYMV were the most common single, and multiple infections in both crops. Watermelons contained more single virus infections than mixed infections (P < 0.001), but this difference was not significant in pumpkins (P = 0.468). In all, single virus infections were significantly higher in watermelons than pumpkins (P < 0.001). This is the first study to report incidence of viruses and virus-like diseases in watermelons and pumpkins in Uganda , and in eastern Africa as a region. The importance of these results with respect to crop production and next steps in virus disease management are discussed.

“…Understanding this three-way relationship is integral to developing control strategies. Cucumber mosaic virus (CMV) has a worldwide distribution with one of the broadest host ranges of any known species of virus (for a recent review see (Jacquemond, 2012)). CMV has a tripartite single-stranded RNA genome, with each genomic RNA packaged separately within icosahedral capsids.…”

The single-stranded, positive-sense and tripartite RNA virus Cucumber mosaic virus (CMV) was used in this study as a method for monitoring the initial stages of virus infection following aphid transmission. The RNA2 of CMV was modified to incorporate, in a variety of arrangements, an open reading frame (ORF) encoding an enhanced green fluorescent protein (eGFP). The phenotypes of five engineered RNA2s were tested in Nicotiana tabacum, Nicotiana clevelandii and Nicotiana benthamiana. Only one construct (F4), in which the 2b ORF was truncated at the 39 end and fused in-frame with the eGFP ORF, was able to systemically infect N. benthamiana plants, express eGFP and be transmitted by the aphid Myzus persicae. The utility of this construct was demonstrated following infection as early as one day post-transmission (dpt) continuing through to systemic infection. Comparisons of the inoculation sites in different petiole sections one to three dpt clearly showed that the onset of infection and eGFP expression always occurred in the epidermal or collenchymatous tissue just below the epidermis; an observation consistent with the rapid time frame characteristic of the non-persistent mode of aphid transmission.

“…Ces quatre virus sont transmis par des pucerons selon le mode non persistant et également transmissibles mécaniquement par la sève à des plantes (Mnari et al, 2008 ;Lecoq et Desbiez, 2008). Contrairement aux autres virus, la gamme d'hôtes du CMV est extrêmement large et distribuée mondialement avec plus de 1200 espèces végétales, représentant 100 familles botaniques incluant les Cucurbitacées et les Solanacées (Palukaitis et Garcia-Arenal, 2003 ;Jacquemond, 2012). La transmission du CMV par les semences a été rapportée avec des taux de transmission variables (0-100%) chez certaines plantes incluant les plantes adventices (O'Keefe et al, 2007 ;Ali et Kobayaski, 2010;Salem et al, 2010).…”
