Cassava (Manihot esculenta Crantz) plays a significant role in the livelihoods of people Africa, particularly Côte d'Ivoire. However, its production is threatened by begomoviruses which cause huge yield losses. Some weeds and food crops intercropped with cassava act as reservoirs, thereby facilitating sustenance propagation mosaic (CMBs), along other begomoviruses. To effectively manage these diseases, it imperative to enhance our understanding various hosts viruses Thus, comprehensive...
Dearth of knowledge exists on identification the begomoviruses and distribution cassava mosaic viruses across key growing regions Sierra Leone. The objective study was to identify map disease (CMD)-associated in farmers' fields Cassava leaf samples were collected 109 smallholder farms during a geo-referenced survey conducted from 10th May 5th June, 2024. Molecular diagnostics carried out viral strains associated with CMD. Findings revealed that infection by stem cutting more...

Abstract Cassava production in Ivory Coast is hampered by cassava mosaic disease (CMD), which caused several begomovirus species. To increase and conserve genetic resources, the Centre National de Recherche Agronomique (CNRA) maintains a germplasm collection of 610 accessions various origins, kept open fields Bouaké Man. We carried out an epidemiological assessment molecular characterization viruses infecting CNRA germplasm. The field Man was less affected CMD (incidence 49.78%, severity...
In Côte d’Ivoire, cassava is the source of calories for about 26 million people and generates significant income stakeholders in value chain. However, its production threatened by Cassava Mosaic Disease (CMD), which causes yield losses up to 70%. This disease remains poorly known among farmers, who often adopt poor cultivation practices that serve amplify spread. To address this issue, Regional Center Excellence transboundary plant pathogens Central West African Virus Epidemiology (WAVE)...
Begomoviruses are a major threat to cassava production in Africa. Indeed, during the 1990s, emergence of recombinant begomovirus (East African mosaic virus-Uganda, EACMV-Ug) resulted crop devastation and severe famine Uganda. In 2023, pre-survey farms at Forécariah, South-West Guinea, 22 samples showing peculiar disease (CMD) symptoms were collected, subsequent laboratory analysis confirmed presence EACMV-Ug samples. Deep DNA-A DNA-B isolates from Guinea indicated that they similar those...
Cassava is a staple in the diet of millions people sub-Saharan Africa, as it can grow poor soils with limited inputs and withstand wide range environmental conditions, including drought. Previous studies have shown that distribution rural populations an important predictor cassava density Africa’s landscape. Our aim to explore relationships between from production disaggregation models (CassavaMap MapSPAM) population density, looking at potential differences countries regions. We analysed...
Cassava is the staple food crop for hundreds of millions people in Africa. In Côte d'Ivoire, it a main source calories over 26 million people. However, cassava mosaic disease (CMD), caused by geminiviruses (CMGs) threaten its production. The development, adoption, and use CMD resistant varieties remain key management strategy. Therefore, 610 accessions from d'Ivoire national germplasm maintained Centre National de Recherche Agronomique (CNRA) research stations cities Man Bouaké were...
Abstract Accurate identification of varieties is paramount to optimizing efficiencies in the management and conservation genetic resources. A relatively inexpensive, rapid methodology required identify putative duplicates from any collection, when morphological traits give insufficient discrimination. Here we select a panel 36 SNPs, visualized using Kompetitive Allele-specific PCR (KASP) system. We used 95 cassava genotypes Côte d’Ivoire that are not few potential which could be put forward...
