“…Although some tolerance and/or resistance to CYSDV has been introduced into a few commercially available cucumber varieties, most varieties lack strong resistance. However, several sources of resistance have recently been identified and introgression into cultivated melon is progressing (López‐Sesé & Gómez‐Guillamón, ; McCreight & Wintermantel, ; McCreight et al ., ). No cucurbit cultivars resistant to BPYV are commercially available and only partial resistance has been identified in melon genetic resources (Lecoq & Desbiez, ).…”

Criniviruses associated with cucurbit yellows disease in Greece and Cyprus: an ever‐changing scene

Cucurbit yellow stunting disorder virus (CYSDV), Cucurbit chlorotic yellows virus (CCYV) and Beet pseudo-yellows virus (BPYV) are whitefly-transmitted criniviruses that cause foliar interveinal yellowing symptoms and result in high economic losses for cucurbit production. CYSDV and CCYV are transmitted by Bemisia tabaci, whereas BPYV is transmitted by Trialeurodes vaporariorum. During 2012-2017, an extensive survey was conducted to identify the viruses causing cucurbit yellows disease in Greece and Cyprus. The study sampled the main cucurbits and alternative hosts in these regions to determine crinivirus incidence, to identify the whitefly species present in the two countries and to characterize molecularly the virus populations. Results showed that CYSDV was the most widespread virus in Greece (49.9%), followed by CCYV (20.3%) and BPYV (18.4%). Bemisia tabaci and T. vaporariorum were identified in 54.5% and 45.6% of whitefly samples, respectively. In Cyprus, CYSDV was predominant (96.7%), followed by CCYV (19.2%), while no BPYV infection was detected. Approximately 15% of weed samples from 17 different species that belong to 12 botanical families were identified as hosts for one or more of these criniviruses. Finally, sequencing of the capsid protein gene of the crinivirus isolates revealed very low levels of genetic diversity, further supporting the genetic stability of crinivirus populations. The results of this long-lasting epidemiological study in two countries of the eastern Mediterranean revealed substantial changes in the relative incidence and distribution of cucurbit-infecting criniviruses and their whitefly vectors over the past 15 years, suggesting the need for adoption of novel management strategies.

“…This fact can be related with the coevolution of host and pathogen in this area, in which ToLCNDV was detected for the first time infecting cucurbits many years ago. Indian cucurbits germplasm has been previously used as source of resistances to viral and fungal pathogens (Dhillon et al, 2012;McCreight et al, 2017). Mendelian analysis of symptom segregation in F 2 and BC 1 s populations derived from PI 604506 and PI 381814, as well as QTL results, suggested the presence of a major recessive gene in chromosome 8 of C. moschata controlling symptoms development and virus titer.…”

“…TGR-1551 is an especially interesting accession, since it carries resistances to WMV, CYSDV, and CABYV. The resistances are different, since it is recessive for WMV [56] and CYSDV [37,79] but is dominant for CABYV. However, despite this different genetic control, for both CABYV and CYSDV the resistance is manifested as an impairment of viral movement in the vasculature [41,78].…”

Cucurbit viruses cause considerable economic losses worldwide. The most common viral diseases affecting this crop family are Potyviruses, Cucumoviruses, Criniviruses, Ipomoviruses, Tobamoviruses, and the emerging Begomoviruses. Four main cucurbit crops are grown worldwide, namely melon, cucumber (Cucumis), watermelon (Citrullus), and squash (Cucurbita). Huge natural variation is also available within each genus, providing valuable sources of genetic resistance to these diseases. Intraspecific and intrageneric diversity and crossability are key factors to select the optimum breeding strategies. Melon and cucumber are diverse species for which intraspecific resistance is available. Conversely, in Citrullus and Cucurbita, wild relatives provide the resistance diversity absent in watermelon and in C. pepo. Some of the classical sources used by breeders, many of which are multi-resistant, come from corresponding origin centers in Asia, Africa, and America, as well as from secondary centers of diversity. Genetic studies have identified dominant and recessive and often complex resistance. Many of the genes identified have been mapped and markers for MAS are available, but higher mapping resolutions are required to identify the corresponding genes. Only a few genes could be cloned and functionally characterized. Efforts are underway to use genome mapping and functional genomics to advance toward a genomic-assisted breeding against viral diseases in cucurbits.
