Abstract:

Rice yellow mottle virus (RYMV) is the major viral constraint to rice production in Africa. RYMV was first identified in 1966 in Kenya and then later in most African countries where rice is grown. Several studies have been conducted so far on its evolution, pathogenicity, resistance genes, and especially its dissemination by insects. Many of these studies showed that, among RYMV vectors, insects especially leaf-feeders found in rice fields are the major source of virus transmission. Many studies have shown that the virus is vectored by several insect species in a process of a first ingestion o

Abstract:

Abstract Rice yellow mottle virus (RYMV) is the most important rice virus in Africa. We examined RYMV transmission via soil and water contaminated with RYMV-infected rice plants and by serial cutting with RYMV-contaminated scissors. Transmission of RYMV via dried rice straw kept at 27°C was also examined. The results showed the virus could be transmitted via soil and water, and by scissors. Rice straw that was RYMV-infected was not infective if it was dried and was kept longer than 42 days. By insect transmission experiments and ELISA, long-horned grasshoppers (Conocephalus spp.) were found to

Abstract:

The sequences of the coat protein gene of a representative sample of 40 isolates of Rice yellow mottle virus (RYMV) from 11 African countries were analysed. The overall level of nucleotide diversity was high ( ∼14 %). Great geographical distances between the sites where isolates were collected were consistently associated with high genetic distances. In contrast, a wide range of genetic distances occurred among isolates spread over short geographical distances. There was no evidence of long-range dispersal. RYMV diversity in relation to land area was eight times greater in East Africa than in

Rice yellow mottle virus (RYMV) of the genus Sobemovirus is a major biotic constraint to rice production in Africa. First reported in Kenya in 1966, RYMV was later found in most countries in Africa where rice (Oryza sativa) is grown (2). During July 2000, plants with leaf yellowing and mottling symptoms were observed in Uganda in a subsistence rice field northeast of Lake Victoria, close to the Nile River. RYMV was detected by using enzyme-linked immunosorbent assay with polyclonal RYMV antisera (1) in the four samples collected. Discriminant monoclonal antibodies revealed that the samples con

Rice yellow mottle virus (RYMV) of the genus Sobemovirus is the main virus infecting rice (Oryza sativa) in Africa. First reported in Kenya (East Africa), RYMV was later found in most countries of East and West Africa where rice is grown, and in Madagascar in the Indian Ocean. In Central Africa however, the disease had never been reported in rice fields. Ninety-eight field samples with typical yellow mottle symptoms from cultivated rice and two wild rice species (Oryza longistaminata and O. barthii) were collected in the Soudano-Sahelian zones, in the north of Cameroon and the south of Chad (C

Abstract:

Since the mid-1980s, rice cultivation has expanded rapidly in Burundi to reach approximately 50,000 ha in 2011. In 2007, leaf mottling, reduced tillering, and stunting symptoms were observed on rice at Gatumba near Bujumbura, causing small patches in less than 10% of the fields. Rice yellow mottle virus (RYMV, genus Sobemovirus), which has seriously threatened rice cultivation in Africa (1) and was recently described in the neighboring Rwanda (3), was suspected to be involved because of similar symptoms. To identify the pathogen that caused the disease in Burundi, a survey was performed in the

Abstract:

Rice yellow mottle virus (RYMV) causes high losses to rice production in Africa. Several sources of varietal high resistance are available but the emergence of virulent pathotypes that are able to overcome one or two resistance alleles can sometimes occur. Both resistance spectra and viral adaptability have to be taken into account to develop sustainable rice breeding strategies against RYMV. In this study, we extended previous resistance spectrum analyses by testing the rymv1-4 and rymv1-5 alleles that are carried by the rice accessions Tog5438 and Tog5674, respectively, against isolates that

Abstract:

Field surveys carried out between 1996 and 1997 in Cote d'Ivoire on weed hosts to detect the occurrence and subsistence of rice yellow mottle virus (RYMV) in nature show that rice and Echinochloa crus-pavonis (Link) harbour the virus. There was consistent detection of RYMV throughout the sampling period in rice samples mostly from the lowland varieties. It is thus evident that RYMV subsists more on rice in nature. This could serve as a source of inoculum for infection to newly transplanted rice in the field.

Le virus de la panachure jaune du riz (virus RYMV pour Rice Yellow Mottle Virus) infecte principalement le genre Oryza et provoque d'importants dégâts sur les cultures de riz en Afrique. Bien que son génome soit rudimentaire, ce virus code des protéines essentielles pour son maintien chez l’hôte en dépit des mécanismes de défense de la plante. Les travaux récents de l’équipe ont permis d’identifier la protéine P1 codée par ce virus comme une protéine qui pourrait, grâce à sa propriété de suppresseur de RNA silencing, permettre au virus de contourner un mécanisme de défense essentiel de l’hôte

Abstract:

Le Rice yellow mottle virus (RYMV) est un virus émergeant qui constitue actuellement une contrainte majeure à la riziculture sur le continent africain. Quelques rares variétés de riz, issues des espèces cultivées de riz africain et asiatique (respectivement Oryza glaberrima et O. sativa), ont récemment été identifiées comme hautement résistantes au RYMV. Ce phénotype de résistance est dû à un gène récessif RYMV1 codant le facteur d'initiation de la traduction eIF(iso)4G1 du riz.Les objectifs de cette thèse sont (i) d'étudier la durabilité de la résistance élevée du riz contre le RYMV avant son

Des approches de génétique et de cartographie classiques y ont été couplées à une approche gène candidat ciblée sur les facteurs d'initiation de la traduction, dont les virus semblent largement dépendre pour infecter les plantes. Dans une première étape, la cartographie des QTL a été optimisée grâce l'analyse combinée de deux populations. Dans une deuxième étape, les gènes des facteurs d'initiation de la traduction eIF4E et eIF4G ont été recherchés sur la séquence génomique du riz

Abstract:

Rice is a staple food in many West African countries, including Niger. However, both regional and national rice production have failed to meet demand due to several constraints, among which is the Rice yellow mottle virus (RYMV). Moreover, attempted intensification of rice cultivation and the introduction of modern cultivars are encouraging farmers towards abandoning local landraces for high yielding, but often susceptible varieties. The study was primarily oriented towards rice pre-breeding, and identifying priorities for rice breeding in Niger in relation to farmers' preferences and their en
