Genetic resources of Wasabi based on the genetic diversity and cultural histories

本研究的目的是通过对山葵及其近缘野生种的遗传结构分析，揭示山葵及其近缘野生种的进化历史，并试图重建山葵及其近缘野生种的进化过程。对10个地区的叶绿体微卫星标记进行了分析。利用它们，在日本的山葵品种的基因分型成功地进行。结果表明，人为干扰对日本野生杜仲属植物的遗传组成和多样性有较大影响。

The aims of my study are, based on the analyses of the current genetic structure of wasabi and its wild relatives, to reveal the evolutionary history of them and to try to reconstruct of the evolutionary process. Chloroplast microsatellite markers from 10 regions were developed and analyzed. Using them, the genotyping of wasabi cultivars in Japan were successfully performed. It was revealed that artificial disturbance had a large impact on the genetic composition and diversity of wild Eutrema species in Japan.
