摘要: 內寄生性食線蟲卵菌是以游走孢子感染線蟲,內寄生於線蟲寄主,並以其為唯一營養來源的一類卵菌,大部分為絕對寄生菌,雖然某些種類目前已可人工培養,但其在自然環境中無腐生時期。不同於其他種類的食線蟲真菌,這類水生菌可藉由游走孢子主動游向寄主,更增加了對寄主之感染能力。本研究即是調查台灣之內寄生性食線蟲卵菌,研究期間共收集了54株菌株,其中已完成科霍氏法則確認其致病性及內寄生性之卵菌菌株共25株,包含7個種,其中2種為新種;25個菌株中,目前已有4個菌株(分別為4種不同的菌種)被發現可誘導產生卵孢子。所蒐集之卵菌在形態上介於Lagenidium、Myzocytium及Myzocytiopsis之間,孢子囊在線蟲寄主體內皆為絲狀,於隔膜處無縊縮,且游走孢子於泡囊中分化成熟,這些特性與Lagenidium屬較相符。而有性繁殖中,藏精器及藏卵器是由相鄰的菌絲片段特化而來,外觀上與菌絲無異;原生質之輸送是藉由隔膜上的孔洞輸送,此特性與Myzocytium較相符。就以上之特性比對,本群菌種與以上所探討的種類皆不相符,然而,在沒有更進一步的證據前,先暫時將其歸於Lagenidium屬中。所有種類皆建立完整之形態描述及圖片,並整合分子親緣分析之結果,探討其種類間之關聯。希望藉由逐漸瞭解這類卵菌之特性,能使其在相關屬之分類上更加完善,並利用其生物特性,希望未來可使用於生物防治等實際應用上。
Endoparasitic nematophagous oomycetes are characterized by infecting nematodes by zoospores, forming hyphae permeating nematodes, and absorbing nutrients exclusively from nematodes. Although they can be cultured in artificial media, it is supposed that they can not grow saprobically in nature. The capability of moving actively towards nematodes makes the infection of nematodes more effective than other nematophagous fungi. The aim of this study was to survey endoparasitic nematophagous oomycetes in Taiwan. Totally 54 isolates were obtained. Among them, 25 isolates have been tested to fulfill the Koch’s postulate regarding the pathogenecity and endoparasitism. They were 7 species identified, two of which were new species. Sexual reproduction has been observed in 4 isolates representing 4 species. These 7 species are characterized by ellipsoid, filamentous or irregular sporangia, producing zoospores from vesicles, forming antheria and oogonia directly from differentiation of adjacent compartments of hyphae. However, the genus Lagenidium is tentatively applied to all the species isolated from nematodes before more conclusive evidences can be acquired. Detail descriptions and photographs are provided in combination with phylogenetic analyses to resolve their relationships. It is expected that the classification of Lagenidium allied genera can be clarified. The understanding of these oomycetes can be useful in the biological control strategy for nematodes.
