摘要

台湾杜鹃花(rhododendron formosanum Hemsl.)是台湾土生种。从野生台湾杜鹃根中分离到一株Rf32真菌，根据其形态特征鉴定为隐孢子虫内生种。内部转录间隔序列分析进一步证实了这一鉴定。本种是台湾真菌区系的新属种。接种rf32后的台湾杜鹃花幼苗生长旺盛，根结在皮层细胞中出现菌丝复合体。结果表明，用隐孢子菌Rf32在离体条件下，台湾杜鹃可以形成镰刀状菌根。

Resynthesis of Ericoid Mycorrhizae in Formosan Rhododendron (Rhododendron formosanum Hemsl.) with an Endophytic Cryptosporiopsis Species

Formosan rhododendron (Rhododendron formosanum Hemsl.) is an indigenous species of the Ericales in Taiwan. The Rf32 fungal strain was isolated from the roots of wild Formosan rhododendron and identified as an endophytic species of Cryptosporiopsis based on its morphological characteristics. This identification was further confirmed by an internal transcribed spacer sequence analysis. This species is a new addition to the fungal flora of Taiwan. In an ericoid-mycorrhizal resynthesis experiment, Rf32-inoculated Formosan rhododendron seedlings exhibited vigorous growth, and the root association showed hyphal complexes in cortical cells. The results demonstrated that Formosan rhododendron can form ericoid mycorrhizae in vitro with Cryptosporiopsis sp. Rf32.

期刊介绍： The Taiwan Journal of Forest Science is an academic publication that welcomes contributions from around the world. The journal covers all aspects of forest research, both basic and applied, including Forest Biology and Ecology (tree breeding, silviculture, soils, etc.), Forest Management (watershed management, forest pests and diseases, forest fire, wildlife, recreation, etc.), Biotechnology, and Wood Science. Manuscripts acceptable to the journal include (1) research papers, (2) research notes, (3) review articles, and (4) monographs. A research note differs from a research paper in its scope which is less-comprehensive, yet it contains important information. In other words, a research note offers an innovative perspective or new discovery which is worthy of early disclosure.
