This genome was sequenced as part of the JGI CSP "1KFG - Deep Sequencing of Ecologically-relevant Dikarya" and more specifically as a part of the Russulaceae Sequencing Project, which seeks to densely sample members of a diverse lineage of ectomycorrhizal (ECM) fungi to examine functional diversity of ECM fungi with a shared evolutionary history.

Lactarius akahatsu QP

Lactarius akahatsu is a member of Lactarius sect. Deliciosi, and seemingly a common species in Japan. It features the generally orange appearance and orange latex which slowly becomes vinaceous red on the latex (Nuytinck et al, 2006). It is unmistakably different from L. hatsudake, a species with red latex from the beginning. Lactarius akahatsu is often found in lowland Pine forests, and widely distributed along with Pinus spp., such as P. densiflora, P. thunbergii and P. liuchuensis (Nagasawa, 1998). Genome sequencing and comparative study with other ectomycorrhizal clades in and out of Russulaceae would provide insights into its specific genomic and evolutionary features within Russulaceae, and also help understand the general genetic features shared by various ectomycorrhizal lineages.
