First report of Moroccan watermelon mosaic virus in pumpkin plants in Brazil.

Cucurbita moschata is widely cultivated in Brazil, and zucchini lethal chlorosis virus, squash mosaic virus, papaya ringspot virus, watermelon mosaic virus have been reported as viral pathogens in this crop in Brazil. The leaf samples of C. moschata showing mosaic, blistering, and yellowing symptoms were collected from a commercial field in Petrolina, Pernambuco state and a commercial field in Juazeiro, Bahia state, in February 2023.

Cucurbit aphid-borne yellows virus from melon plants in Brazil is an interspecific recombinant.

Melon plants with severe yellowing symptoms from in Brazil were analyzed by high-throughput sequencing. Sequences homologous to the genome of the polerovirus cucurbit aphid-borne yellows virus (CABYV) were frequently retrieved. Two draft CABYV genomes were assembled from two pooled melon samples that contained an identical putative recombinant fragment in the 3' region with an unknown polerovirus.
