Taimo is a paddy cultivar of Taro ( (L.) Schott) that is traditionally consumed in the Ryukyu Archipelago, Japan. Its origin remains unknown, although it has been identified as belonging to a haplotype commonly found in tropical and subtropical regions. However, previously developed genetic markers were insufficient to resolve the genetic relationships among cultivars that share the same haplotype. To address this limitation, we sequenced the complete chloroplast genome of cv. Taimo. The comparison of the obtained sequence with the currently published complete and partial chloroplast genomes revealed that cv. Taimo is most closely related to the paddy cultivar Lipu from southern mainland China. These findings suggest that the ancestors of cv. Taimo were introduced to the Ryukyus from China.
台芋是一种芋头（(L.) Schott）的水稻品种，传统上在日本琉球群岛食用。其起源尚不清楚，尽管它已被鉴定为属于热带和亚热带地区常见的单倍型。然而，先前开发的遗传标记不足以解析具有相同单倍型的品种之间的遗传关系。为了解决这一限制，我们对台芋品种的完整叶绿体基因组进行了测序。将获得的序列与目前已发表的完整和部分叶绿体基因组进行比较，结果表明台芋品种与中国南部大陆的水稻品种荔浦关系最为密切。这些发现表明，台芋品种的祖先从中国被引入到琉球。
