“…Plants with a mixed infection of ZYMV and CABYV also developed symptoms more severely than plants infected by only one of these viruses. CABYV concentrations were significantly increased (2-20 times) while those of ZYMV were unchanged (Bourdin & Lecoq, 1994).…”

Zucchini yellow mosaic potyvirus (ZYMV), first isolated in Italy in 1973, described in 1981, and then identified in all continents within a decade, is one of the most economically important viruses of cucurbit crops. It is efficiently aphid-transmitted in a nonpersistent manner and it is also seed-borne in zucchini squash, which could have contributed to its rapid spread worldwide. Biological variability has been observed among ZYMV isolates, concerning host range, symptomatology and aphid transmissibility. More recent studies also revealed a serological and molecular variability. The survival of ZYMV in areas where cucurbits are not grown throughout the year remains to be elucidated, because very few natural over-wintering hosts have been identified so far. Partial control of ZYMV can be achieved by limiting transmission of the virus to the crops by aphids, using adapted cultural practices. Cross-protection with a mild strain has been shown to be effective against most ZYMV isolates. Resistance genes found in cucurbit germplasms are currently being introduced into cultivars with good agronomical characteristics. Pathogen-derived resistance strategies using the expression of ZYMV genes in transgenic plants have also been developed and appear promising. Nevertheless, the high biological variability of ZYMV justifies a careful evaluation of the deployment of genetic control strategies in order to increase their durability.

“…In synergism, it is generally recognized that one virus, which is not increased in accumulation (i.e. functioning essentially as a catalyst), acts as an up-regulator of the replication and/or movement of a unrelated virus, usually increasing the intensity of symptoms induced compared with single infection by either virus alone (Rochow & Ross, 1955 ; Calvert & Ghabrial, 1983 ; Poolpol & Inouye, 1986a , b ; Goldberg & Brakke 1987 ; Sano & Kojima, 1989 ; Vance, 1991 ; Anjos et al ., 1992 ; Bourdin & Lecoq, 1994 ; Pruss et al ., 1997 ). In most of the above cases of synergism, the ‘catalytic virus’ is a potyvirus.…”

“…Synergism is often observed between WMV-2 and other viruses infecting cucurbits, which can be expressed either by higher rate of virus replication or more severe symptoms. This was demonstrated, in particular for mixed infection caused by WMV-2 and poleroviruses, such as cucumber aphid-born virus (CABYV) [9].…”

Aim. Screening of vegetable crops for mixed viral infections caused by 8 viruses, and evaluation of relative share for different combinations of pathogens using serological methods for plant virus diagnostics. Methods. Double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was performed for detection of viral antigens. Results. For this study, the samples from plants with virus-like symptoms were collected from the agroecosystems in 4 regions of Ukraine during three vegetative seasons in 2019-2021. Plant samples were tested for presence of the following viruses: cucumber mosaic virus (CMV), watermelon mosaiс virus 2 (WMV2), zucchini yellow mosaic virus (ZYMV), tomato mosaic virus (ToMV), tobacco rattle virus (TRV), potato virus Y (PVY), potato virus X (PVX), and tomato spotted wilt virus (TSWV). Among the screened plants with virus-like symptoms, three viruses were the most common: CMV, WMV2 and ZYMV, with the incidence rate of 32%, 33% and 29%, respectively. Apart from monoinfected plants, several patterns of mixed infections were shown typically induced by two and less commonly by three viruses (CMV+WMV2+ZYMV). From these patterns of mixed infections, five groups of pathogens were registered. Conclusions. In this work, we have analyzed cucurbit and solanaceous vegetable crops with virus-like symptoms for viral infections caused by 8 pathogens, and established virus combinations inducing mixed infections in the field. Five groups of pathogens were demonstrated as such combinations: CMV+ToMV, CMV+PVY, CMV+WMV2, CMV+ZYMV, and WMV2+ZYMV, with CMV+ToMV being the most common for tested plants. Also, there was one group of pathogens formed by three viruses CMV+WMV2+ZYMV. CMV has been shown present in every group of mixed viral infections in plants from both families, Cucurbitaceae and Solanaceae. The incidence rate for these combinations differed from 4 to 8%. The presented results are important in the context of ecology and epidemiology of viral diseases of vegetables.
