摘要:
以优化后的漆酶培养基为基础,将RT-PCR、RACE技术相结合,从红平菇菌株中获得漆酶基因cDNA全长及Genomic DNA全长序列,Genomic DNA大小为2 344 bp。通过对漆酶基因cDNA全长和Genomic DNA全长序列的比较,结果显示该基因包含13个外显子和12个内含子。基因cDNA全长为1 746 bp,其中包含1个完整的ORF,长度为1 590 bp,编码529个氨基酸。序列在氨基酸水平上与桃红侧耳Pleurotus salmoneostramineus的氨基酸序列具有较高的同源性,相似性达97%,与齿耳菌Steccherinum murashkinskyi漆酶氨基酸序列相似性达到72%。通过SEFA-PCR的方法,扩增得到漆酶基因起始密码子上游长1 126 bp的启动子序列。分析表明,该启动子区域上除分布有TATA-box、CAAT-box、AP2等基本的转录起始元件外,还存在多个潜在的顺式作用元件序列位点,包括4个MRE元件、2个CreA热击元件、2个STRE元件、1个NIT2元件、1个HSEs元件、1个XRE异生物质反应元件、4个氮因子结合位点等。不同外源诱导物可以调节红平菇HP1漆酶基因的表达。
