摘要: 为了筛选与红曲菌产桔霉素相关的基因,应用抑制性消减杂交(SSH)构建了两个红曲菌的cDNA消减文库。利用分子生物学软件从这两个文库中找出八条同源序列,通过Blast软件对这八条序列进行分析,结果显示,它们可能是新的基因片段,递交后被Genbank接收。

Abstract: Two cDNA subtractive libraries of Monascus were constructed by suppression subtractive hybridization(SSH) and screened of correlative genes from the citrinin biosynthetic pathway in Monascus species. All clones in the two libraries were sequenced and the results were analyzed by bioinformatic softwares. There were 8 homologous ESTs in both libraries. Comparing with other ESTs by BLAST, these ESTs were novel, and were accepted by Genbank.

Key words: Monascus, citrinin, SSH, subtractive cDNA library
