Ganoderma lucidum의 계통분류(系統分類)

Classification of Strains of Ganoderma lucidum

Ganoerma lucidum의 인공재배(人工栽培)로 얻은 자실체(子實體)의 형태적(形態摘) 특성(特性)을 기초(基礎)로 계통(系統)을 분류(分類)하고 전기영동특성(電氣泳動特性)과의 관련성(關聯性)을 검토하였다. 영지균은 버섯의 형태(形態)와 윤문(輪紋)의 유무에 따라 4계통(系統)으로 분류(分類)되었으며 그중 편각 윤문형(輪紋形)이 가장 많았고 전형적 녹각형은 소수였다. 자실체(子實體)의 모양 즉 편각과 녹각, 갓 표면(表面)의 윤문(輪紋) 유무(有無)는 유전성(遺傳性)이었다. 영지균사(菌絲) 및 자실체(子實體)의 전기영동(電氣泳動)에 의한 단백질(蛋白質), Peroxidase, Esterase 및 Leucine Amino Peptidase Isozyme Pattern을 조사(調査)한 결과(結果) 한국자생영지균(韓國自生靈芝菌)은 유전형질(遺傳形質)에 다양성(多樣性)을 보였다. 그중 Esterase Isozyme Pattern은 편각과 녹각간에 차이가 컸고 동(同) 계통(系統)간에는 높은 유사도(類似度)를 보여 계통분류(系統分類) 결과(結果)와 일치하였다.

This study was carried out to investigate some morphological characters of fruit bodies of Ganoderma lucidum and to classify the fungus on the bases of the genetic character. Some of the isolates of the fungus which originally have the kidney-shaped fruit bodies produced the antler-shaped fruit bodies on artificial media and the latter characters were inherited. Pattern of the pileus surface and thickness of the pileus of the fruit bodies were also considered to be hereditary. Although morphology of the pileus margin and fruiting mode of the fungus were variable among the isolates, they were greatly influenced by environment conditions. Ganoderma lucidum could be classified into two groups and four strains according to the morphology of the fruit bodies on artificial cultivation media. Electrophoretic patterns of esterase, peroxidase, leucine aminopeptidase(LAP) and proteins of fruit bodies and mycelia of Ganoderma lucidum showed high genetic variation. Isozyme patterns of esterase of the mushroom mycelia were applicable for the classification of strains of the fungus. Patterns of proteins, leucine aminopeptidase and peroxidase did not indicate any genetic relation among the fungus strains.
