摘要


切取絲核菌生長在馬鈴薯葡萄糖瓊脂(PDA)菌絲圓盤,倒置在載玻片上讓菌絲長出,再以4.6-diamidino-2-phenyl-indole (DAPI)(pH 7)或Acridine orange (pH 10)染色,可以使細胞核清楚的顯現。用DAPI染色時,可再用Fluorescent brightener 28複染,以增强細胞壁及隔膜之染色效果。本染色技術簡便快速,並能成功地把絲核菌的細胞核染色。

並列摘要


Young hyphae of Rhizoctonia spp. grown from potato dextrose agar plug on glass slides were used to stain with fluorescent dyes for nuclei and septa. Nuclei and septa were stained very clearly and easily obserable with 4,6'-diamidino 2-phenyl-indole (DAPI) in pH 7 buffer and Acridine orange in pH 10 buffer. When stained with DAPI, Fluorescent brightener 28 could be used for double staining, which increased the efficiency of cell wall and septa staining. This technique was very simple, and could finish staining within a short period of time.
