摘要: 构建含有Swollenin基因(swo基因)的香菇表达载体,并通过PEG(polyethylene glyeol)介导的原生质体转化法实现对香菇的遗传转化,转化效率约为1个转化子/μg质粒DNA。PCR和杂交检测结果表明,swo基因已经整合到香菇的基因组中;栽培实验结果表明,两个转化子都能正常出菇,而且转化子Ⅱ表现出优良的生物学性状,将swo基因转化到香菇中对香菇新品种的培育进行探索。

关键词: 遗传转化, 香菇, swollenin, 表达载体

Abstract: Swollenin can loosen cellulose and enhance its enzymatic hydrolysis. An expression plasmid containing swollenin(swo) gene was constructed and successfully transformed to Lentinus edodes by PEG-mediated transformation method with an efficiency of 1 transformant/μg plasmid DNA. PCR and Southern blot indicated that swollenin was successfully integrated to the genome of L. edodes. Both tested transformants of L. edodes can form fruit bodies and transformant II still revealed good cultivation characteristics. Transformation of swo gene into L. edodes can provide an exploration into breeding of new varieties of L. edodes.

Key words: Lentinus edodes, swollenin gene, expression plasmid, genetic transformation
