Abstract Rhizomania, caused by Beet necrotic yellow vein virus (BNYVV) is an economically important disease of sugar beet. Management includes the use of single resistance (Rz) genes. However, strains with the ability to overcome the widely used Rz1 resistance gene have already been reported. The mechanisms associated with these genes are unknown, therefore increased understanding of the host defense response may lead to more durable sources of rhizomania resistance. Non-targeted metabolome profiling, coupled with targeted phytohormone quantification, was applied to characterize the metabolic and signaling pathways associated with BNYVV infections in sugar beet. Clear differences in metabolites were identified following pathogen infection independent of plant genotype particularly those associated with host lipid composition or other membrane associated functions.

甜菜坏死黄脉病毒感染期间甜菜（Beta vulgaris）的代谢紊乱

摘要 由甜菜坏死黄脉病毒（BNYVV）引起的根瘤病是甜菜经济上的重要病害。管理包括使用单一抗性 (Rz) 基因。然而，已经报道了能够克服广泛使用的 Rz1 抗性基因的菌株。与这些基因相关的机制尚不清楚，因此对宿主防御反应的更多了解可能会导致更持久的根瘤菌抗性来源。非靶向代谢组分析与靶向植物激素定量相结合，用于表征与甜菜 BNYVV 感染相关的代谢和信号通路。
