An annotated list of viruses infecting or associated with passion fruit (Passiflora spp.)

Abstract

Abstract Plants belonging to the genus Passiflora (family Passifloraceae) are found in tropical regions and are cultivated worldwide. Among them, the yellow passion fruit (P. edulis f. flavicarpa Deg.) is the most economically important species. This fruit is widely consumed fresh and is used in the juice industry. Additionally, it is employed as a natural ingredient in cosmetic and medicinal products. The yellow passion fruit is also grown as an ornamental plant in gardens and landscaping. One of the primary challenges in passion fruit cultivation is the occurrence of viral diseases, which can decrease both fruit production and quality, posing an ongoing threat to growers. Efficient strategies for managing and controlling viruses in these crops, particularly those that focus on developing resistant genotypes, rely on an extensive understanding of the viral diversity affecting the crop. In recent years, advances in technology and the development of new tools for virus detection and identification have led to a significant increase in the number of viruses reported to infect or be associated with Passiflora species and passion fruit hybrids. This review catalogs the known diversity of DNA and RNA viruses affecting the passion fruit crop. To date, this diversity includes 74 species (accepted and proposed) across 17 families and 25 genera of viruses.
