Viruses are most frequently discovered because they cause disease. To expand knowledge of plant-associated viruses beyond these narrow constraints, non-cultivated plants of the Tallgrass Prairie of the United States were systematically surveyed for evidence of viruses. This report discusses putative viruses of the family Secoviridae identified by the survey. Sequence analysis suggests the presence of at least six viruses in the study site, including Bean pod mottle virus, Maize chlorotic dwarf virus, three previously undescribed viruses within the subfamily Comovirinae and one unclassifiable virus.
病毒通常是由于引起疾病而被发现的。为了在这些狭隘的限制之外扩展对植物相关病毒的认识，对美国高草草原的非栽培植物进行了系统调查，以寻找病毒的证据。本报告讨论了通过调查确定的属于细环病毒科的假定病毒。序列分析表明，研究地点至少存在六种病毒，包括豆荚斑驳病毒、玉米矮花叶病毒、在 Comovirinae 亚科内的三种以前未描述的病毒和一种无法分类的病毒。
