“…Considering that such molecular criteria are precise and such criteria are accepted by the International Committee of Virus Taxonomy for designation of species of Potyvirus (Van Regenmortel et al, 2000), we classified our UESB-01 sample, which caused PWD, as a strain of the CABMV.…”

“…Conventional measures for managing potyviruses in passionfruit are expensive. Many researchers therefore are making efforts to develop strategies involving engineered resistance, cross protection and resistant germplasms (Peasley 1981;Alfenas et al 2005;Trevisan 2005). Successful deployment of these strategies requires knowledge about the genetic structure of the potyvirus being targeted.…”

Passionfruit (Passiflora edulis) is widely cultivated in tropical and subtropical regions around the world. Several viruses of the genus Potyvirus pose serious threat to passion fruit production. The origin, dispersal and evolution of these potyviruses, however, are poorly understood. Here, we investigated the genetic structure of telosma mosaic virus (TelMV), a potyvirus that infects passionfruit in East and Southeast Asia, after a survey of its incidence in passionfruit plants of China. The phylogeny inferred from 140 nucleotide sequences of the coat protein (CP) gene of TelMV, including 96 determined in this study, separated this virus into 4 clades. TelMV isolates from passionfruit were placed into Clade 1–3, while those from other plant species into Clade 4. Interestingly, TelMV isolates of passionfruit from Thailand were found in all the three clades of Clade 1–3, but those from China and Vietnam were found exclusively in Clade 1. Nevertheless, TelMV isolates within Clade 1 tended to cluster according to their geographical origin. Geographical populations from Thailand, Taiwan and Hainan islands of China showed significant genetic differences with one another and with those from Guangxi, Fujian, Guangdong, Yunnan and Jiangsu provinces of China. Altogether, these data suggest that several distinct TelMV clades had arisen from the passionfruit of Thailand, but only one of which was dispersed. In expanding its distribution, this clade of TelMV has undergone geography-associated evolution. Further studies on this hypothesis may shed new insights into mechanisms underlying the emergence of potyviral diseases in passionfruit plants.

“…This disease is a limiting factor for the cultivation of the species in certain regions (Damatto Junior et al., 2014). In Brazil, it was initially identified in plantations of yellow passion fruit ( Passiflora edulis f. flavicarpa) and sweet passion fruit ( Passiflora alata ) in 1978, in the municipality of Feira de Santana, Bahia, and since then, the virus has spread to all Brazilian passion fruit‐producing regions (Narita et al., 2012; Trevisan, 2005).…”

Brazil is the world's largest producer and consumer of passion fruit, with a plantation area of approximately 41,000 hectares and a production of 554,000 tons. The major states producing the fruit are Bahia, Ceará and Santa Catarina, with a production of approximately 170,000, 94,000 and 46,000 tons, respectively. Paraná is the eighth largest passion fruit producer in Brazil and is responsible for 3.6% of the national production that amounts to a revenue of 49.5 million reais (IBGE, 2017). Currently, one of the major phytosanitary issues associated with passion fruit crop production is the virus infestation that causes the hardening of the fruits. This disease is a limiting factor for the cultivation of the species in certain regions (Damatto
