Abstract

Fungi in the genus Termitomyces are external symbionts of fungus-growing termites. The three rhizogenic Termitomyces species T. eurrhizus, T. clypeatus, and T. intermedius, and one species similar to T. microcarpus that lacks pseudorrhiza, have been reported from Ryukyu Archipelago, Japan. In contrast, only two genetic groups (types A and B) of Termitomyces vegetative mycelia have been detected in nests of the fungus-growing termite Odontotermes formosanus. In this study, we investigated the relationships between the mycelial genetic groups and the basidiomata of Termitomyces samples from the Ryukyu Archipelago. We found that all the basidioma specimens and the type B mycelia formed one clade that we identified as T. intermedius. Another clade consisted of the type A mycelia, which showed similarity to T. microcarpus, was identified as T. fragilis. Our results indicate that the Japanese T. eurrhizus and T. clypeatus specimens should re-named as T. intermedius.

基于三个基因座系统发育分析的日本琉球群岛白蚁属物种分类修正。
白蚁属真菌是生长真菌的白蚁的外部共生体。据报道,在日本琉球群岛发现了3种生根白蚁,分别是eurrhizus、T. clypeatus和T. intermedius,以及1种类似于T. microcarpus但没有假根的白蚁。相比之下,在台湾白蚁巢中只检测到两个白蚁营养菌丝遗传群(A型和B型)。本文研究了来自琉球群岛的白蚁菌丝遗传群与担子瘤的关系。我们发现所有的担子瘤标本和B型菌丝体形成了一个分支,我们确定为T. intermedius。另一个由A型菌丝体组成的进化枝与微腕骨霉相似,被鉴定为脆弱霉。本研究结果表明,日本的eurrhizus和T. clypeatus标本应重新命名为intermedius。

期刊介绍: Mycoscience is the official English-language journal of the Mycological Society of Japan and is issued bimonthly. Mycoscience publishes original research articles and reviews on various topics related to fungi including yeasts and other organisms that have traditionally been studied by mycologists. The research areas covered by Mycoscience extend from such purely scientific fields as systematics, evolution, phylogeny, morphology, ecology, physiology, biochemistry, genetics, and molecular biology, to agricultural, medical, and industrial applications. New and improved applications of well-established mycological techniques and methods are also covered.
