A multiple alignment of the capside protein sequences of nepoviruses and comoviruses suggests a common structure Inra
Le Gall; Candresse, T.; Dunez, J..
The amino acid sequences of the regions encoding the structural proteins of eleven nepoviruses and five comoviruses, two genera of the familyComoviridae, have been aligned. The properties predicted by computer analysis (three-dimensional-3D-structure, hydrophobicity) are also correlated along this alignment, and aligned to the experimentally determined 3D structure of two comoviruses. It can thus be assumed that the 3D structure of the unique nepovirus coat protein matches that of the bipartite protomer found in the comovirus particles. In this model, the spatial locations of two amino-acid motifs characteristic of nepoviruses are in close vicinity, at the external surface of the virion. The coat proteins of nepoviruses and comoviruses may thus share a...

Aetiology and ecology of a yam mosaic disease in Burkina Faso IRD
Goudou-Urbino, C.; Konate, G.; Quiot, J.B.; Dubern, Jean.
Yam virus diseases were surveyed for 3 years in Burkino Faso. Mosaic and green vein banding symptoms were observed on two species (#Dioscorea cayenensis rotundata$ and #Dioscorea alata$) in the south-west and southern aeras, and on the Pilimpikou yam cultivar in the central area. Using electron microscopy, ELISA and host range studies, it was found that plants were infected with a potyvirus similar to yam mosaic virus in host range, morphology and serology. This virus was not detected in the southern area but occurred at a low rate (13%) in the south-west and more frequently (71.5%) in the central aera. Healthy yam plants were exposed to natural infection for 5 months in these two areas and checked for virus contamination by ELISA. Tubers from markets were...

Amélioration et valorisation de l'igname : rapport d'exécution pour la période du 01.07.92 au 31.08.93 IRD
Dubern, Jean; Givord, Louise (collab.); Goudou-Urbino, C. (collab.); Konate, G. (collab.); Malaurie, Bernard (collab.); Quiot, J.B. (collab.).
Cette seconde étude a été centrée sur la connaissance de la culture #in vitro$ de l'Igname, la sanitation des vitroplants par culture de méristème, par thermothérapie et par chimiothérapie. Cette étude a également comporté l'étude de la diversité biologique du virus de la Mosaïque de l'Igname (YMV), la mise au point d'un kit de diagnostic, sa connaissance particulière de virus au Burkina Faso (distribution géographique, épidémiologie, diversité), en Guadeloupe et en Guyane. L'indexation de la collection de vitroplants a permis de diagnostiquer en dehors du YMV, un virus de type Potexvirus et de soupçonner la présence d'un Cucumovirus et d'un autre Potyvirus.

Banques de séquences pour la taxinomie des phytovirus : l'analyse factorielle des correspondances appliquée à la classification des géminivirus IRD
Desbois, D.; Fauquet, Claude; Fargette, Denis; Vidal, G..
Cet article présente un exemple d'utilisation des banques de données moléculaires, comme source d'information, et de l'analyse factorielle des correspondances, comme technique d'analyse, pour la recherche taxinomique, ceci dans un pays en développement. L'application de cette technique statistique multivariée à la classification des virus de plantes permet de dégager des critères taxinomiques cohérents basés sur la composition en acides aminés, dinucléotides et codons de la protéine capsidaire. Ces critères aboutissent à une typologie pertinente du groupe des géminivirus, issue d'un algorithme ascendant de classification hiérarchique. (Résumé d'auteur)

Characterization of peanut mottle virus in Cote d'Ivoire IRD
Samad, A.; Thouvenel, Jean-Claude; Dubern, Jean.
Un virus a été récemment isolé de l'Arachide dans la région septentrionale de la Côte d'Ivoire, pays où il n'avait pas encore été diagnostiqué. Il provoque, sur les feuilles, des marbrures, des dépressions internervaires ainsi que des taches très typées vert clair et vert foncé. Ce virus a été caractérisé ; il s'agit d'une souche du virus de la Marbrure de l'Arachide (Peanut Mottle Virus), virus membre du groupe des Potyvirus ; les études ont porté sur la gamme des plantes hôtes, le mode de transmission, la morphologie des particules, les propriétés physico-chimiques et sérologiques, en comparaison avec d'autres virus de l'Arachide.

Components of resistance of cassava to african cassava mosaic virus IRD
Fargette, Denis; Colon, L.T.; Bouveau, R.; Fauquet, Claude.
Components of resistance of cassava (#Manihot esculenta$) to African cassava mosaic virus (ACMV) and their interrelationships were confirmed and quantified in a series of experiments at Adiopodoumé (Ivory Coast, West Africa). The response to virus infection and to #Bemisia tabaci$ infestation of a large collection of cassava, including local cultivars and others derived from inter-specific #M. glaziovii$ hybrids was assessed. A consistent correlation was found between virus titre, symptom intensity, disease incidence and non-systemicity (recovery) which suggests that they are different expressions of the same genetic resistance. By contrast, there was no correlation between whitefly infestation and incidence of ACMV, suggesting that resistance to virus and...
