Movement of a Plant Virus from Cultivated to Wild Hosts

9407919关于病毒对自然植物种群的影响，人们知之甚少。这项研究项目的目的是测量一种植物病毒在自然和农业社区之间的移动，并确定这种病毒对生长在旧田演替地点的野草的影响。该项目的重点是大麦黄矮病病毒，这是一种通过蚜虫传播给野生和栽培牧草的广泛病毒。这项研究将提高我们对病毒与它们的野生和本地宿主之间的关系，以及疾病和遗传物质在农业植物和它们的野生近亲之间传播的可能性的理解。研究结果将直接应用于植物病理学、病虫害防治和农业生产。它们还可能应用于田间种植转基因作物的环境影响研究。

9407919 Power Relatively little is known about the impact of viruses on natural plant populations. The objectives of this research project are to measure the movement of a plant virus between natural and agricultural communities and to determine the effect of this virus on wild grasses growing in old-field succession sites. This project focuses on the barley yellow dwarf virus, a widespread virus transmitted to both wild and cultivated grasses by aphids. This research will improve our understanding of the relationship between viruses and their wild and native hosts and on the potential for disease and genetic material to spread between agricultural plants and their wild relatives and vice versa. The results will have direct application in plant pathology, pest control, and agriculture. They may also have application to environmental-impact studies of the field cultivation of genetically altered crop plants.
