| The nucleoprotein and non-capsid protein of maize yellow stripe virus (MYSV) were purified from naturally or experimentally infected maize or sorghum plants. In SDS-PAGE, the apparent molecular weight of the nucleoprotein was 35,6 KD, and that of the non-capsid protein was 14,7 KD. Similar to tenuiviruses, the nucleoprotein of MYSV was associated with fine filaments and the non-capsid protein formed typical needle-shaped crystals. Following a 2-day acquisition feeding period on MYSV-infected plants, vector leafhoppers (#Cicadulina chinai$) remained highly infective for 21 days. Antisera to the nucleoprotein and non-capsid protein of MYSV were produced and used for detection of this virus in several host plants and vector leafhoppers in Egypt. Dot-blot and... |

| 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.

| Antisera to the nucleoprotein of maize yellow stripe tenui-like virus (MYSV) were produced and used for detection of this virus in several host plants and vector leafhoppers in Egypt. Dot-blot and direct antigen coating (DAC) ELISA were used to detect MYSV in naturally or experimentally infected maize, wheat, barley, oats, and the graminaceous weeds #Bromus wildenowii$, #Cenchrus biflorus$, #Dichanthium annulatum$, #Digitaria sanguinalis$, #Echinochloa colonum$, #Setaria verticillata$ and #S. viridis$. In maize leaves, differences in virus titer appeared to be correlated with leaf age and with MYSV symptom-types. Dot-blot and DAC-ELISA were used also to detect MYSV in naturally or experimentally infective leafhoppers (#Cicadulina chinai$). (Résumé d'auteur) |
