人们对不同树种进行了许多系统地理研究，以阐明避难所的位置和更新世期间的定居模式。然而，对草本植物的大规模系统地理学研究很少，特别是对适应干扰的草本植物的研究更是稀少。印度艾草是一种生长迅速的多年生草本植物，在开阔的栖息地发现。为了检验该物种遗传结构的基本信息，我们调查了日本各地种群内和种群间的叶绿体DNA变异。我们在28个日本群体的604个个体中检测到26个单倍型。单倍型A1具有广泛的地理分布，其近亲存在于当地。一些推测的祖先血统主要在九州地区被发现。这可能是因为在更新世期间，有几个谱系从欧亚大陆经由朝鲜半岛迁徙到九州北部沿海，A1单倍型向北扩展，而另一些则保留在南部地区。亲缘关系较远的单倍型主要存在于关东地区。由于这些单倍型在该地区的地理分布模式被认为是不自然的，这些单倍型可能来自过去几十年来用于植被重建的商业来源。
Many phylogeographic studies of various tree species have been conducted to elucidate the locations of refugia and the colonization patterns during the Pleistocene. However, only a few large-scale phylogeographic studies have been conducted on herbaceous plants, especially scarce on herbs that are adapted to disturbance. Artemisia indica is a fast-growing perennial herb found in open habitats. To examine the basic information on the genetic structure of this species, we investigated the chloroplast DNA variation within and among populations across Japan. We detected 26 haplotypes in 604 individuals from 28 Japanese populations. The haplotype A1 had wide geographic distribution, and its close relatives were locally present. Some putative ancestral lineages were found mainly in the Kyushu region. This may be because several lineages migrated from the Eurasian continent to the northern coast in Kyushu via the Korean peninsula during the Pleistocene, and the A1 haplotype expanded northward, whereas others remained in southern areas. Phylogenetic distant haplotypes were present mainly in the Kanto region. Because the geographic distribution pattern of these haplotypes in this region is believed to be unnatural, these haplotypes may be derived from commercial sources for re-vegetation during the last few decades.
