Physalis peruviana is a perennial solanaceous plant that has recently been established as a commercial crop in Brazil. This work reports the near-complete genome sequence, particle morphology, and plant host responses to a putative new sobemovirus, named "physalis rugose mosaic virus". The virus, characterized by isometric particles of ca. 30 nm in diameter, causes foliar symptoms of mosaic, malformation and blistering, accompanied by stunting. The near-complete genome sequence comprises 4175 nucleotides and contains five open reading frames that are similar to those of other sobemoviruses. In addition to P. peruviana, the new virus systemically infected Capsicum annuum, Nicotiana tabacum and Solanum lycopersicum by mechanical inoculation. Thus, this virus may cause disease in these crops in the field.
秘鲁番茄是一种多年生茄科植物，最近在巴西被确立为商业作物。本工作报道了一种假定的新 sobemovirus 的近完整基因组序列、粒子形态和植物宿主反应，命名为“Physalis rugose mosaic virus”。该病毒特征为等径粒子，直径约 30nm，引起叶片花叶、畸形和疱斑症状，伴随矮化。近完整基因组序列包含 4175 个核苷酸，包含与其他 sobemoviruses 相似的五个开放阅读框。除了秘鲁番茄外，新病毒还通过机械接种系统感染辣椒、烟草和番茄。因此，该病毒可能在田间这些作物中引起疾病。
