Rice yellow mottle virus (RYMV) exemplifies the key role in plant virus emergence of the early steps of crop extension and intensification in traditional agriculture. In East Africa, RYMV emerged in the 19(th) century after rice intensification along the Indian Ocean coast, and later spread inland concomitantly with rice introduction. In West Africa, the contrasted history of rice cultivation among regions differently shaped RYMV populations. A biogeographical approach - which jointly considers the spatial distribution of the virus and its hosts over time - was applied to reach these conclusions. We linked the evolution of RYMV over the past two centuries to a geographical map of the history of rice cultivation in Africa.
稻黄花叶病毒（RYMV）是农业传统中作物扩展和集约化早期阶段在植物病毒出现中起关键作用的范例。在东非，RYMV 于 19 世纪在印度洋沿岸水稻集约化之后出现，随后随着水稻的引入而向内陆传播。在西非，不同地区的水稻种植历史截然不同，塑造了 RYMV 群体。采用生物地理方法（同时考虑病毒及其宿主随时间的空间分布）得出了这些结论。我们将过去两个世纪 RYMV 的进化与非洲水稻种植历史的地理地图联系起来。
