A new yellowing disease of cucurbits caused by a luteovirus, cucurbit aphid-borne yellows virus
Serological analysis, nucleic-acid-hybridization experiments and host-range studies indicate that the virus CABYV is distantly related to, but distinct from, beet western yellows virus (BWYV), and it is proposed to name this virus cucurbit aphid-borne yellowsirus (CABYVs), and consider it as a tentative new member of the luteovirus group.

Zucchini yellow mosaic virus
The high biological variability of ZYMV justifies a careful evaluation of the deployment of genetic control strategies in order to increase their durability, and resistance genes found in cucurbit germplasms are currently being introduced into cultivars with good agronomical characteristics. Expand

Analysis of genome organization and sequence homologies indicate that CABYV is a member of luteovirus Subgroup 2 (other sequenced members: beet western yellows virus, potato leafroll virus, and barley yellow dwarf virus, RPV isolate) and appears to be most closely related to beet western yellsows virus.

Biological and serological variability, evolution and molecular epidemiology of Zucchini yellow mosaic virus (ZYMV, Potyvirus) with special reference to Caribbean islands.
Sequence analysis on a 250 nucleotide fragment including the N-terminal part of the coat protein coding region revealed one major group of strains, and some highly divergent isolates from distinct origins of ZYMV. Expand
Mutations in the helper component protease gene of zucchini yellow mosaic virus affect its ability to mediate aphid transmissibility.

It is proposed that more than one site in HC-Pro may be functionally related to aphid transmissibility, particularly in the helper-deficient ZYMV. Expand
Epidemiological risks from mixed virus infections and transgenic plants expressing viral genes.
The chapter reviews the general aspects of vector specificity in different virus groups, as this could be altered either by recombination or by virus–transgene interactions, and discusses various means of minimizing the perceived risks. Expand
The nucleotide sequence of Watermelon mosaic virus (WMV, Potyvirus) reveals interspecific recombination between two related potyviruses in the 5′ part of the genome
The full-length sequence of WMV was obtained and it was confirmed that this virus is very closely related to SMV in most of its genome; however, there is evidence for an interspecific recombination in the P1 protein, suggesting that WMV has emerged through an ancestral recombination event. Expand
Watermelon chlorotic stunt virus from the Sudan and Iran: Sequence Comparisons and Identification of a Whitefly-Transmission Determinant.
ABSTRACT The genomes of two Watermelon chlorotic stunt virus (WmCSV) isolates, one from the Sudan and one from Iran, were cloned and sequenced. Sequence relationship with other geminiviruses… Expand
Viruses of cucurbit crops in the Mediterranean region: an ever-changing picture.
This chapter describes the major cucurbit viruses occurring in the Mediterranean basin, discusses factors involved in their emergence and presents options for developing sustainable control strategies. Expand
Pepper Mild Mottle Virus, a Plant Virus Associated with Specific Immune Responses, Fever, Abdominal Pains, and Pruritus in Humans
The data suggest the possibility of a direct or indirect pathogenic role of plant viruses in humans and linked the presence of PMMoV RNA in stool with a specific immune response and clinical symptoms. Expand
