Passion Fruit Woodiness Virus

In Victoria cucumber mosaic virus (CMV) has been shown to be the cause of the woodiness disease of Passifloua edulis. This virus causes a slow decline of infected P. edulis seedlings, and a more rapid decline of vines grafted onto P. caerulea rootstocks. In Queensland a similar disease of passion fruit also occurs. The Queensland disease was shown to be caused by a virus which differed markedly from CMV, This virus, which is designated herein as passion fruit woodiness virus (PWV), has flexuous rod-shaped particles about 670 mµ in length. PWV was shown to be stylet-borne by the aphid Myzus persicae and to be transmitted to Phaseolus vulgaris and Sesbania exaltata by sap inoculation. The physical properties of PWV were determined, and two isolates of the virus were purified and antisera prepared against them.

Passion Fruit Woodiness Virus

The Passion fruit woodiness virus (PWV) is the most important virus affecting passion fruit (Passiflora edulis f. flavicarpa Deg.) crops in Brazil. The main purpose of this work was to select mild strains of PWV and to evaluate their protective effect against a severe strain of the virus. Three mild strains were selected from outstanding plants found in orchards severely affected by the virus (F-101, F-102 and F-103) and three others were obtained from blisters formed in passion fruit vine leaves showing mosaic (F-99, F-144 and F-145). The protective effect of the mild strains was evaluated for vines under greenhouse and field conditions. Plants pre-immunized with mild strains F-101, F-102 and F-144, in a greenhouse, had partial protection against the severe strain PWV-SP. In a first field experiment, all passion fruit vines pre-immunized with the six selected mild strains showed severe symptoms of the disease, approximately four months after the challenge inoculation with the PWV-SP strain. Results from a second field experiment, with vines pre-immunized with strains F-101 and F-144, followed by a quantitative evaluation of the mild strains in different leaves of the protected plants, indicated that breakdown in protection seems to be related to the low concentration and/or irregular distribution of the mild strains in leaves, which allows the existence of infection sites available for the establishment of the severe strain. Pre-immunization was not an appropriate alternative for the control of the passion fruit woodiness disease.

Resumo. Estudou-se o efeito da alimentação com lagartas de Dione juno juno (Cramer) (Lepidoptera: Nymphalidae), criadas em diferentes genótipos de maracujazeiro: Passiflora edulis Sims., Passiflora edulis f. flavicarpa Deg. (Seleção de Jaboticabal), P. edulis f. flavicarpa (cv. Sul Brasil) e P. edulis f. flavicarpa (cv. Maguary FB-100), Passiflora alata Dryand, Passiflora serrato-digitata Linn. e Passiflora foetida Linn. sobre imaturos e adultos de Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae). O experimento foi conduzido sob condições controladas (temperatura: 26 ± 1°C, UR de 60 ± 10% e fotofase de 14 horas). Grupos de cinco ninfas de P. nigrispinus de 2º ínstar foram mantidos em recipientes plásticos (4,5 cm de altura e 7,5 cm de diâmetro), contendo as presas no seu interior. Diariamente, cinco lagartas de D. juno juno de 10 dias de idade (cerca de 2,0 cm de comprimento), criadas em folhas dos diferentes genótipos de maracujazeiro foram oferecidas aos predadores. O experimento constou de 10 repetições, totalizando 50 ninfas por tratamento. Foram avaliadas, diariamente, as durações e sobrevivência de cada instar; peso de ninfas (24 horas após a ecdise) e de adultos. Os resultados mostram a influência de genótipos de maracujazeiro sobre o terceiro nível trófico, onde lagartas criadas no genótipo P. edulis f. flavicarpa Sel. Jaboticabal mostraram-se mais adequadas ao desenvolvimento do predador. Os resultados obtidos nesse trabalho mostram a influência de genótipos de maracujazeiro sobre o terceiro nível trófico. O genótipo P. edulis f. flavicarpa cv. Sul Brasil mostra-se menos adequado ao predador, sugerindo de forma negativa a associação entre a resistência de plantas e o uso do controle biológico. Já os genótipos P. edulis e P. edulis f. flavicarpa Seleção de Jaboticabal podem ser utilizados juntamente com o predador, pois essas cultivares não afetaram o terceiro nível trófico. P. edulis f. flavicarpa cv. Maguary FB-100, considerado pouco adequado ao desenvolvimento de lagartas de D. juno juno, afetou o predador, resultando em associação negativa entre esse genótipo e o controle biológico.Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) Fed with Dione juno juno (Cramer) (Lepidoptera: Nymphalidae) Caterpillars, Raised in Different Passion fruit Genotypes, Adults and Immatures BiologyAbstract. The development of Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) nymphs fed with Dione juno juno (Cramer) (Lepidoptera: Nymphalidae) larvae reared on leaves of the passion fruit genotypes Passiflora edulis Sims., Passiflora edulis f. flavicarpa Deg. (Seleção de Jaboticabal), P. edulis f. flavicarpa (cv. Sul Brasil) and P. edulis f. flavicarpa (cv. Maguary FB-100), P. alata, P. serrato-digitata and P. foetida. The experiment was conducted under controlled conditions (temperature: 26 ± 1°C, RH = 60 ± 10% and photophase of 14 hours). Second instar nymphs of the predator were kept in plastic cups (4.5 cm high and 7.5 cm wide) groups of five. Ten-day-old (approx. 2 cm) D. juno juno larvae reared on leaves of different passion fruit genotypes were provided daily to P. nigrispinus. The experiment was carried out with 10 replications, totalizing 50 nymphs per treatment. Daily evaluations were performed to measure the duration and viability of each instar, the body mass of nymphs (24 hours after each ecdysis) and adults, and the duration and viability of the nymph phase and adult longevity under starvation. Results show the influence of passion fruit genotypes at the third trophic level, since larvae reared with P. edulis f. flavicarpa (Seleção de Jaboticabal) have shown to be more adequate for predator development. The results of this experiment show the influence of passion fruit genotypes on the third trophic level. The genotype P. edulis f. flavicarpa cv. Sul Brasil has a less appropriate to the predator, suggesting a negative way the association between host plant resistance and use of biological control. Already P. edulis and genotypes P. edulis f. flavicarpa Jaboticabal Selection can be used along with the predator because these cultivars did not affect the third trophic level. P. edulis f. flavicarpa cv. Maguary FB-100, considered ill-suited to the development of larvae of D. juno juno, affected the predator, resulting in a negative association between this genotype and biological control.

This article describes the incidence and etiology of a viral disease of passion fruit in Uganda. Symptoms, including those characteristic of passion fruit woodiness disease (PWD), were observed on 32% of plants in producing areas. Electron microscopic observations of infected tissues revealed flexuous filaments of ca. 780 nm. Enzymelinked immunosorbent assays indicated a serological relationship with Cowpea aphid-borne mosaic virus (CABMV) and Passion fruit ringspot virus (PFRSV). In host range studies, only species in the families Solanaceae and Chenopodiaceae were susceptible, and neither Vigna unguiculata nor Phaseolus vulgaris became infected. Coat protein (CP) gene sequences of eight isolates exhibited features typical of potyviruses and were highly similar (88 to 100% identity). However, the sequences had limited sequence identity with CP genes of two of the three potyviruses reported to cause PWD: East Asian Passiflora virus and Passion fruit woodiness virus (PWV). Deduced amino acid sequences for the CP of isolates from Uganda had highest identity with Bean common mosaic necrosis virus (BCMNV) (72 to 79%, with evolutionary divergence values between 0.17 and 0.19) and CABMV (73 to 76%, with divergence values between 0.21 and 0.25). Based on these results and in accordance with International Committee for Taxonomy of Viruses criteria for species demarcation in the family Potyviridae, we conclude that a previously unreported virus causes viral diseases on passion fruit in Uganda. The name “Ugandan Passiflora virus” is proposed for this virus.

The main objective of the present study was to evaluate the effect of the sunhemp (Crotalaria juncea) host species on the protective ability of two mild strains of Passion fruit woodiness virus (PWV), named F-101 and F-144, which had failed to protect passion flowers (Passiflora edulis f. flavicarpa) in previous experiments. The nucleotide sequences of the capsid protein (CP) gene and the 3'-non-translated region (3'-NTR) of these mild strains and the severe strain of PWV-SP were compared to confirm their relationship. The results of two protective tests with sunhemp plants in the greenhouse and one test under field conditions showed that all plants infected with either mild strain were protected against infection and/or symptom expression of the severe strain of PWV-SP. Evaluation of the relative concentration of the mild strains in sun hemp leaves showed an apparent uniformity in virus distribution in the leaf tissues, different than that which was previously reported for these mild strains in passion flower leaves. These results agree with previous studies that showed the effect of the concentration of the protective strains and the host species in the protection process.

Writing from a wide range of historical perspectives, contributors to the anthology shed new light on historical, theoretical and empirical issues pertaining to the documentary film, in order to better comprehend the significant transformations of the form in colonial, late colonial and immediate post-colonial and postcolonial times in South and South-East Asia. In doing so, this anthology addresses an important gap in the global understanding of documentary discourses, practices, uses and styles. Based upon in-depth essays written by international authorities in the field and cutting-edge doctoral projects, this anthology is the first to encompass different periods, national contexts, subject matter and style in order to address important and also relatively little-known issues in colonial documentary film in the South and South-East Asian regions. This anthology is divided into three main thematic sections, each of which crosses national or geographical boundaries. The first section addresses issues of colonialism, late colonialism and independence. The second section looks at the use of the documentary film by missionaries and Christian evangelists, whilst the third explores the relation between documentary film, nationalism and representation.
