Sequencing of the chloroplast genome of Taimo, a paddy cultivar of Taro ( <i>Colocasia esculenta</i> (L.) Schott) in the Ryukyu Archipelago

Taimo is a paddy cultivar of Taro (<i>Colocasia esculenta</i> (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.
