Outline of Final Research Achievements |
In this study we first aimed to clarify diversity of hypogeous (sequestrate) fungi in island regions of Japan and addressed their systematics. We further planned to conduct molecular clock analyses based on divergence of hypogeous fungi that showed vicariance between the mainland of Japan and the smaller islands such as Ryukyu Islands coupled with the dates of strait formation between these regions. We found novel genus- and species-level lineages of hypogeous fungi and described several new taxa in the Boletaceae (e.g., the genus Turmalinea). Furthermore, we showed certain degrees of genetic divergence between species- and infraspecies-level lineages of hypogeous fungi that reflected the vicariance between the mainland and smaller islands. The degrees of divergence is, however, significantly varied among lineages, and a few of them showed little or no divergence. We therefore concluded that is it premature to apply the genetic information of the vicariance to molecular clock analyses.
