抄録

The genetic diversity and genetic structure of B. xylophilus in 8 populations of the Kyushu region were elucidated using the nucleotide polymorphism of 10 EST loci. Considerable genetic differences among regional populations were observed with the gene differentiation(GST) of 0.53, which showed that more than half of the total gene diversity(HT=0.63) was possessed among regional populations. The HT values of 8 regional populations were between 0.12 and 0.59. Sendai, Shintomi, Matsuura, and Karatsu populations were rich in gene diversity(0.59, 0.57, 0.56, and 0.55), and their high GST(0.43, 0.35, 0.25, and 0.25) indicated that the genetic compositions were notably different among the populations within damaged trees(subpopulations). On the other hand, in Amakusa and Miyazaki populations, extremely low gene diversity(0.12 and 0.18) and small GST(0.01 and 0.02) were confirmed, which showed that little genetic difference existed among subpopulations. It seemed that a bottleneck effect or founder effect had a great impact on the formation of these regional populations. The genetic diversity of the regional populations was polarized in Kyushu.
