Over a hundred years of research on plant viruses has led to a detailed understanding of viral replication, movement, and host–virus interactions. The functions of vast viral genes have also been annotated. With an increased understanding of plant viruses and plant–virus interactions, various viruses have been developed as vectors to modulate gene expressions for functional studies as well as for fulfilling the needs in biotechnology. These approaches are invaluable not only for molecular breeding and functional genomics studies related to pivotal agronomic traits, but also for the production of vaccines and health-promoting carotenoids. This review summarizes the latest progress in these forefronts as well as the available viral vectors for economically important crops and beyond.

植物病毒学为生物技术提供多样化的工具集


一百多年来对植物病毒的研究使人们对病毒复制、运动和宿主与病毒相互作用有了详细的了解。大量病毒基因的功能也已被注释。随着对植物病毒和植物与病毒相互作用的了解不断加深，各种病毒已被开发为载体来调节基因表达，用于功能研究以及满足生物技术的需求。这些方法不仅对于与关键农艺性状相关的分子育种和功能基因组学研究非常有价值，而且对于疫苗和促进健康的类胡萝卜素的生产也非常有价值。这篇综述总结了这些前沿领域的最新进展以及用于经济重要作物及其他作物的可用病毒载体。
