《万卷集》是日本最大、最早的诗集，收录了世纪初至8世纪世纪中期的4,500多首诗歌，让读者得以一窥这一时期的日本生活。其中一首诗，据说是由皇后Koken写于公元752年的夏天，描述了夏天泽兰属植物的秋天外观，据说是最早的植物病毒病症状的书面记录。在这里，我们发现，从受影响的泽兰植物中分离出的一种双生病毒和一种伴随的卫星成分共同造成了一千多年前皇后首次注意到的壮观的叶面展示。图1皇后Koken的一首诗的早期手写版本，描述了泽兰植物黄色叶子的秋天感觉（这里翻译成草）生长在夏天。文字是这样的：“也许它确实霜冻/在这个村庄的早晨/因为我在夏天的田野里看到的草/已经变黄了”。这首诗摘自藤原敦方（1071-1120）编辑的《万言书》的瑞书科书版，由坂本伸之提供，并由日本奈良教育大学提供复制。
The Man'yoshu, meaning 'collection of ten thousand leaves', is the largest and earliest anthology of Japanese poetry — it contains over 4,500 poems written between the early seventh century and the middle of the eighth century, and provides a glimpse of Japanese life during that period. One poem, attributed to the Empress Koken and written in the summer of 752ad, describes the autumnal appearance of eupatorium plants in summer and is reputedly the earliest written record of the symptoms of a plant virus disease. Here we show that a geminivirus and an accompanying satellite component isolated from affected eupatorium plants are together responsible for the spectacular foliar display that was first noted by the Empress more than a millennium ago.Figure 1An early handwritten version of a poem by the Empress Koken describing the autumnal feel of the yellow leaves of eupatorium plants (translated here as grass) growing in summer.The text reads: “Perhaps it does frost/ In this village morn by morn/ For the grass I saw in the field of summertime/ Has already turned yellow”. The poem, taken from the Rui-shu-ko-shu edition of the Man'yoshu edited by Atsukata Fujiwara (1071–1120), was provided by Nobuyuki Sakamoto and is reproduced by courtesy of the Nara University of Education, Japan.
