“…Three viruses are recorded infecting passionfruit (Passiflora edulis Sims) in Australia: passionfruit woodiness potyvirus (PWV; 15,16), cucumber mosaic cucumovirus (CMV; 5,8,16), and passionfruit rhabdovirus (PRV; 11). A mixed infection of CMV and PWV has been associated with passionfruit tip necrosis (PTN) disease on the far north coast of New South Wales (13). PWV is universal in most commercial passionfruit cultivars in Australia and also occurs in wild Passiflora spp.…”

A carlavirus was found to be widespread in commercial passionfruit (Passiflora edulis) plantings in New South Wales and Queensland. The particles observed were flexuous rods with mean dimensions of 651 × 12 nm. The particles often occurred in cells as aggregates but were never associated with pinwheel inclusion bodies, as is typical with passionfruit woodiness potyvirus. The particles showed a strong affinity (by immunoelectron microscopy) for antiserum prepared against Passiflora latent carlavirus (PLV) from Germany but increasingly less affinity for antisera against potato viruses S and M and PLV from the United States. Survey results indicated that PLV has been present in Australian passionfruit for more than 10 years and is widespread in most commercial cultivars in New South Wales and Queensland. The virus was twice found in wild Passiflora suberosa, once in wild P. subpeltata, and once in a feral seedling of P. edulis near an infected planting of P. edulis.

Los virus que afectan las plantas son de gran importancia en la producción agrícola de Colombia. Diferentes estudios indican que las pérdidas económicas causadas por estos problemas fitosanitarios, podrían evitarse con un mayor conocimiento sobre estos patógenos y mediante un sistema de manejo como guía. Los viveros, productores, comercializadores y consumidores, se beneficiarían de productos de calidad al controlar las fuentes de virus. Los acuerdos de libre comercio han dado lugar a una expansión de la producción agrícola y a la proliferación de cientos de viveros que no han sido objeto de inspección minuciosa por parte del estado. Este artículo presenta los principales virus que afectan dos importantes frutales exóticos de exportación para Colombia, los frutos de pasión (Passiflora sp.) y la uchuva (Physalis peruviana). A su vez, esquematiza lo que sería un programa de producción y certificación de material vegetal sano para los viveros y la creación de un programa nacional de certificación de material, dirigido por el Ministerio de Agricultura y Desarrollo Rural y el Instituto Colombiano Agropecuario (ICA); apoyado por las universidades con carreras agrícolas, centros de investigación y laboratorios fitosanitarios que proporcionarían un sistema de supervisión y control adecuados, para el material vegetal y esquemas de asistencia técnica oportuna para los agricultores. Esta iniciativa interinstitucional también apoyaría la implementación y el ajuste de las resoluciones fitosanitarias del ICA en semillas (R. 2046/2003), material de propagación en frutales (R. 3180/2009) y la resolución recientemente aprobada para el transporte interno de material vegetal (R. 3973/2016). Los productores necesitan acceso a material vegetal sano, para proteger la seguridad alimentaria nacional y mantener una ventaja competitiva en el mercado.

“…Cross-protection would be an alternative control method. However, reports of a synergistic effect between PWV and Cucumber mosaic virus (CMV), family Bromoviridae, genus Cucumovirus, causing tip necrosis (Pares et al, 1985) have hindered the use of cross-protection. Breeding for resistance is complicated by self-incompatibility and inter-specific incompatibility in Passiflora species (Martin & Nakasone, 1970;Lopes, 1994;Bruckner et al, 2002).…”

Transgenic passionfruit expressing RNA derived from Cowpea aphid-borne mosaic virus is resistant to passionfruit woodiness disease

Sixteen transgenic yellow passionfruit (Passiflora spp.) plants (R 0 ) were obtained which express a non-translatable transgenic RNA corresponding to the 3' region of the NIb gene and the 5' region of the CP gene, derived from the genome of a Brazilian isolate of Cowpea aphid-borne mosaic virus (CABMV). The transgenic plants were propagated by stem cuttings and challenged by sap inoculation with isolates CABMV-MG1 and CABMV-PE1. One transgenic plant (TE5-10) was resistant to the isolate CABMV-MG1, but susceptible to CABMV-PE1. The remaining transgenic plants developed systemic symptoms, equal to non-transformed plants, when inoculated with either isolate. The absence of virus in TE5-10 plants was confirmed by indirect ELISA. Transcription analysis of the transgene demonstrated that the TE5-10 plant did not accumulate transgenic mRNA, even before inoculation. After inoculation, viral RNA was only detected in plants inoculated with CABMV-PE1. These results confirm that the transgenic plant TE5-10 is resistant to isolate CABMV-MG1, and suggest that the resistance mechanism is post-transcriptional gene silencing, which is already activated in the transgenic plants before virus inoculation.Additional keywords: Passionfruit woodiness virus, PWV, potyvirus, resistance. RESUMO Plantas transgênicas de maracujá-amarelo expressando um RNA derivado do genoma do Cowpea aphid-borne mosaic virus são resistentes ao endurecimento dos frutosDezesseis plantas transgênicas (R 0 ) de maracujá-amarelo (Passiflora spp.) foram obtidas expressando um RNA não-traduzível correspondente à região 3' do gene NIb e 5' do gene CP de um isolado brasileiro do CABMV. As plantas R 0 foram propagadas vegetativamente por estaquia e inoculadas com os isolados CABMV-MG1 e CABMV-PE1. Uma das plantas (TE5-10) foi resistente ao isolado CABMV-MG1, porém suscetível ao isolado CABMV-PE1. As demais plantas transgênicas foram suscetíveis a ambos os isolados, apresentando sintomas sistêmicos semelhantes ao de plantas não-transformadas. A ausência de replicação viral nas plantas TE5-10 foi confirmada por ELISA indireto. A análise da transcrição do transgene nas plantas TE5-10 demonstrou que estas não acumulam o mRNA transgênico, mesmo antes da inoculação com o vírus. Após a inoculação, o RNA viral foi detectado apenas em plantas inoculadas com o isolado CABMV-PE1. Esses resultados confirmam que a planta TE5-10 é resistente ao isolado CABMV-MG1, e sugerem que o mecanismo da resistência é baseado em silenciamento gênico pós-transcricional, o qual já se encontra ativado nas plantas antes da inoculação com o vírus.Palavras-chave adicionais: Passionfruit woodiness virus, PWV, potyvirus, resistência, maracujá amarelo.
