Viruses of yams (Dioscorea spp.): Current gaps in knowledge and future research directions to improve disease management. Viruses, 14 (9), n.spéc. Special Issue Emerging Plant Viruses:1884, 23 p.

Résumé : Viruses are a major constraint for yam production worldwide. They hamper the conservation, movement, and exchange of yam germplasm and are a threat to food security in tropical and subtropical areas of Africa and the Pacific where yam is a staple food and a source of income. However, the biology and impact of yam viruses remains largely unknown. This review summarizes current knowledge on yam viruses and emphasizes gaps that exist in the knowledge of the biology of these viruses, their diagnosis, and their impact on production. It provides essential information to inform the implementation of more effective virus control strategies.
