Phellinus noxius is a pathogenic fungus that causes brown root rot disease in a variety of tree species. This fungus is distributed in tropical and sub-tropical regions of Southeast and East Asia, Oceania, Australia, Central America and Africa. In Japan, it was first discovered on Ishigaki Island in Okinawa Prefecture in 1988; since then, it has been found on several of the Ryukyu Islands. Recently, this fungus was identified from the Ogasawara (Bonin) Islands, where it has killed trees, including rare endemic tree species. For effective control or quarantine methods, it is important to clarify whether the Japanese populations of P. noxius are indigenous to the area or if they have been introduced from other areas. We developed 20 microsatellite markers from genome assembly of P. noxius and genotyped 128 isolates from 12 of the Ryukyu Islands and 3 of the Ogasawara Islands. All isolates had unique genotypes, indicating that basidiospore infection is a primary dissemination method for the formation of new disease foci. Genetic structure analyses strongly supported genetic differentiation between the Ryukyu populations and the Ogasawara populations of P. noxius. High polymorphism of microsatellite loci suggests that Japanese populations are indigenous or were introduced a very long time ago. We discuss differences in invasion patterns between the Ryukyu Islands and the Ogasawara Islands.

“…The researches on Fomitiporia have receieved great attention because of their curative properties these years. It reported that the fungus is particularly rich in pregnenolone type triterpenes and exhibited positive effects on treating cancer (Ota et al, 2014;Chepkirui et al, 2018). In this way, the three fungi would be good candidates as materials for developing food or medicines.…”

This study aimed to evaluate the effects of solid-state fermentation (SSF) (25℃, 35 days) with three filamentous fungi (Helvella lacunosa X1, Agaricus bisporus AS2796 and Fomitiporia yanbeiensis G1) on the nutrient substance and antioxidant properties of quinoa. As a result, it showed that the nutritional components in fermented - quinoa varied with the starter strains. Among the three starter fungi, AS2796 gave the highest protein contents (28.46 g/100g), which was 2.34 times higher than control (unfermented quinoa); F. G1 gave the lowest values of soluble starch and crude fat (18.46 g/100g and 3.31 g/100g), which were 35.2% and 58.5% lower than that of control, respectively; and H. X1 gave the highest content of reducing sugar (5.62g/100g), which was 5.50 times higher than that of control. The total phenolics of quinoa fermented by AS2796 reached its maximum value (1.38mg/g, 35days), which was 1.97 holds higher than control. According to antioxidant test in vitro of ethanolic extracts of fermented quinoa, it showed that H. X1 gave the highest DPPH radical scavenging capacity and reducing power, F.G1 gave the highest superoxide anion radical scavenging ability. Either the starter strains or fermentation time resulted in a significant change in the antioxidant activities.
