Cherry leaf roll virus (CLRV) is a plant pathogen of economic and ecologic importance. It is globally distributed in a wide range of forest, fruit, and ornamental trees and shrubs. In several areas of cherry and walnut production CLRV causes severe losses in yield and quality. With current reference to the rapid dissemination and strong symptom expression in Finnish birches and the Germany-wide distribution of CLRV in birches and elderberry, we continuously investigate and gradually reveal CLRV transmission pathways as by pollen, seeds or water. However, modes and interactions responsible for the wide intergeneric host transmission as well as for the exceptional CLRV epidemic in Fennoscandia still remain unknown. In this project systematic studies shall investigate biological vectors as a causal agent to finally derive control mechanisms and strategies to avoid new epidemics in different hosts and geographic regions. Detailed monitoring of the invertebrate fauna of birch stands/forests and elderberry plantations in Germany and Finland shall reveal potential vectors to subsequently study them in detail by approved virus detection methods and transmission experiments. Molecular analyses of the CLRV coat protein shall prove its role as a viral determinant for a virus/vector interaction. Consequently, this project essentially will contribute important answers on the CLRV epidemiology, and this will be a key element within the first network of research on plant viral pathogens in forest trees.

樱桃卷叶病毒（CLRV）是一种具有经济和生态重要性的植物病原体。它广泛分布于全球范围内的森林、果树和观赏树木和灌木中。在一些樱桃和核桃生产地区，CLRV 会造成产量和质量的严重损失。鉴于目前芬兰桦树中 CLRV 的快速传播和强烈症状表现以及 CLRV 在桦树和接骨木浆果中的德国范围内的分布，我们不断研究并逐步揭示 CLRV 通过花粉、种子或水传播的途径。然而，导致广泛属间宿主传播以及 Fennoscandia 中异常 CLRV 流行的模式和相互作用仍然未知。在该项目中，系统研究将调查生物媒介作为致病因素，最终得出控制机制和策略，以避免在不同宿主和地理区域出现新的流行病。对德国和芬兰的桦树林/森林和接骨木种植园的无脊椎动物群的详细监测将揭示潜在的媒介，以便随后通过批准的病毒检测方法和传播实验对其进行详细研究。 CLRV 外壳蛋白的分子分析应证明其作为病毒/载体相互作用的病毒决定因素的作用。因此，该项目本质上将为 CLRV 流行病学提供重要答案，这将成为第一个林木植物病毒病原体研究网络中的关键要素。
