Morphology and Zoospore Ultrastructure of Rhizophydium macroporosum (Chytridiales)

大孔根生壺菌(Rhizophydium macroporosum)形態及游孢子超微結構之研究

摘要


本文描述一種臺灣新紀錄大孔根生壺菌(Rhizophydium macroporosum),使用光學顯微鏡及掃描式電子顯微鏡觀察菌體外部形態,並以穿透式電子顯微鏡觀察游孢子內部的微細構造。經由純培養,游孢子發育為成熟的菌體,游孢子囊大型,成熟的游孢子同時從多個釋放孔擠出於透明膠狀物質中,隨後游孢子散開。游孢子超微結構為該菌種首次報導,顯示基本上具有根生壺菌型游孢子之特徵。

Rhizophydium macroporosum Karling is reported as a new record to Taiwan. It is isolated from mud of pond, and has been pure cultured on 1/4YpSs medium. A mature zoosporangium possesses one to six exit papillae. Zoospores emerge en masse from the discharged pores and are surrounded by gelatinous material. The ultrastructure of zoospore of this fungus is first reported here.
