Passionfruit woodiness caused by cowpea aphid-borne mosaic virus (CABMV, genus Potyvirus, family Potyviridae) is the most damaging and widespread viral disease affecting passionfruit in Brazil (Nascimento et al. 2006). In recent years, high incidence and severity of virus-like symptoms, such as blisters, mosaic, and leaf deformation, were reported by passionfruit growers in Bahia, the main passionfruit producing state in Brazil. Symptomatic leaves of passionfruit were collected in Lençóis (P. edulis, n = 14; P. alata, n = 3; and P. cincinnata, n = 4) and Jussiape (P. edulis, n = 9), Bahia State, in 2015. Double-stranded RNA was extracted from these 21 samples, pooled, and sequenced in an Illumina HiSeq 2500 sequencer (Macrogen, South Korea). De novo assembly of the reads using the ABYSS 1.9 program with K-mer = 64 resulted in 22 contigs corresponding to CABMV. Moreover, five contigs with high nucleotide identity (85 to 98%) with sequences of cucurbit aphid-borne yellows virus (CABYV) (genus Polerovirus, family Luteoviridae) were also identified. A CABYV sequence (JF939814.1) was used as a reference to map the short reads using Geneious 9.1, and 33,290 reads were mapped, resulting in a consensus contig of 5,643 nt comprising a nearly complete virus genome (CABYV-PF, MH257573). The CABYV-PF sequence shares 87 to 94% nt identities with the genome sequences of several CABYV isolates. To validate the high-throughput sequencing results, the primers CABYV_377F (5′-GATACAACGAAACCAGACAAACCTT-3′) and CABYV_1186R (5′-TTGCTTAACACAGATGCATGAGTTT-3′) covering genes P0/P1 of CABYV-PF were designed. These and the primers CE-9 and CE-10, which amplify the CP/MP genes (Kassem et al. 2013), were used to recover CABYV segments from the passionfruit pooled RNA. Amplicons of the expected size of 795 and 598 nt were obtained, cloned into pJET1.2 (ThermoFisher, U.S.A.), and Sanger sequenced. Sequences of two clones from CP/MP shared 100% identity with the CABYV-PF sequence and had the highest identity (99%) with a CABYV isolate from Italy (EF029113.1). Sequences of two clones corresponding to P0/P1 showed 97 to 100% identity with CABYV-PF and shared 95 to 96% identity with a CABYV isolate from melon collected in Brazil (LC217994.1). To assess the incidence of CABYV in all samples, reverse transcription polymerase chain reaction (RT-PCR) was performed with primers CE-9/CE-10 in RNA extracted from individual plants. After electrophoresis, Southern blot analysis was carried out. The gel was blotted to a nylon membrane that was hybridized with a CABYV-CP/MP-derived 32P-labeled probe. Presence of CABMV was evaluated by RT-PCR with primers CABMVM1MX_3726F/CABMVM1MX_5039R (Fontenele et al. 2018). The incidence of CABYV in plants from Lençóis was 52%. The three sampled Passiflora species were found to be infected with CABMV (eight P. edulis, two P. alata, and one P. cincinnata). CABMV was detected in 91% of the plants, and mixed infection with CABYV and CABMV was identified in 48% of the plants. The CABYV and CABMV infection frequencies were lower in Jussiape (11 and 55%, respectively), and no mixed infection was detected. CABYV has a wide host range and infects cucurbits and weeds from Brassicaceae, Lamiaceae, and Asteraceae in many countries. However, this is the first record of CABYV in passionfruit in the world. CABYV and CABMV are vectored by Aphis gossypii and Myzus persicae, and the more severe symptoms observed in the field may be owing to mixed infections. Studies are in progress to characterize CABYV isolates from passionfruit and to determine its distribution, alternative hosts, and interactions with CABMV.References:Fontenele, R. S., et al. 2018.
