Origin of waxy common millet, Panicum miliaceum L. in Japan

We developed PCR-based markers for genotyping Waxy genes in common millet (Panicum miliaceum L.) and proposed a new hypothesis on the origin and dispersal of waxy type of Japanese landraces. I-2-K staining indicated that almost all the Japanese landraces had waxy endosperm. Based on the PCR and dCAPs analyses of two waxy loci on different genomes we concluded that there were at least two possible lineages in Asian continent that had independent dispersal pathways into Japan. Most Japanese common millet had the similar genotypes with those in Korean Peninsula but a few particularly from northern part of Japan had common genotypes in northeastern China and Primorskaya Province of Russia.
