About Sugi genome database

Since ancient times, sugi (Cryptomeria japonica) has been a very valuable tree species in Japan because of its excellent attributes (straight bole, rapid growth, ease of processing, and pleasant color and scent) for use in house beams, rafters, and boards (Ohba 1993). This species is an allogamous, wind-pollinated conifer species that is frequently used for commercial afforestation in Japan. The plantation of this species occupied ca. 45 % of the total artificial plantation of 10 million ha because of importance of Japanese forestry. The modern natural forests of this species are widely distributed in moist temperate regions from Aomori Prefecture (40°42'N) to Yakushima Island (30°15'N) in the Japanese Archipelago (Hayashi 1960).

We have conducted genome project of this species since 1998 and could obtain EST information, DNA markers, linkage maps, and genetic diversity in this species. We have also studied another Japanese conifer, Chamaecyparis obtusa, which is closely related to C. japonica. Therefore, we provide these genome information in this site.
