【摘要】 采用等高锁状均质电场（ＣＨＥＦ）凝胶电泳技术，对黑木耳（Ａｕｒｉｃｕｌａｒｉａ　ａｕｒｉｃｕｌａ）电泳核型进行分析，以酿酒酵母（Ｓａｃｃｈａｒｏｍｙｃｅｓ　ｃｅｒｉｖｉｓｉａｅ）菌株ＹＰＨ７５５和祭酒裂殖酵母（Ｓｃｈｉｚｏｓａｃｃｈａｒｏｍｙｃｅｓ　ｐｏｍｂｅ）菌株ＡＳ２．２１４的染色体ＤＮＡ大小作为分子量标记，估计黑木耳基因组中至少包含９条ＤＮＡ分子量在８５０ｋｂ至５８００ｋｂ之间的染色体，多数染色体ＤＮＡ分子量在１０００ｋｂ至３４００ｋｂ之间，基因组大小在２２Ｍｂ以上。更多还原

【Abstract】 Electrophoretic karyotype of jelly basidiomycetes Auricularia auricula was analysed by use ofcontour-clamped homogeneous electric field (CHEF) electrophoresis. Using chromosomal size standards fromSchizosaccharomyces pombe AS2.214 and Xaccharomyces cervisiae YPH755, the chromosomal number of Aauricula was estimated to be at least 9 ranging in size from 850kb to 5800kb. The total genome size was over22Mb.更多还原
