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.

小行星9407919 关于病毒对自然植物种群的影响，人们知之甚少。 本研究项目的目标是测量自然和农业社区之间的植物病毒的运动，并确定这种病毒对生长在老田继承网站的野草的影响。 该项目的重点是大麦黄矮病毒，这是一种通过蚜虫传播到野生和栽培禾本科植物的广泛病毒。 这项研究将提高我们对病毒及其野生和本地宿主之间关系的理解，以及疾病和遗传物质在农业植物及其野生亲缘植物之间传播的潜力，反之亦然。 其结果将直接应用于植物病理学，害虫防治和农业。 它们也可应用于转基因作物田间栽培的环境影响研究。
