摘要: 以葡萄糖为碳源生长的解脂耶氏酵母(Yarrowia lipolytica)为对照组,以油酸为碳源生长的Y. lipolytica为实验组,利用Illumina高通量测序平台对两者进行转录组测序,通过多种生物信息学方法对数据进行分析处理。对照组的测序结果共得到17 923 921 clean reads;实验组的测序结果共得到22 656 852 clean reads。两个样品差异表达基因的分析显示共有536 个显著性差异表达基因,376 个基因表达上调,160 个基因表达下调。通过GO和KEGG富集分析可以了解这些差异基因参与的生物学调控。本研究为解脂酵母分子生物学的进一步研究提供了参考。

Abstract: In this study, comparative transcriptomic analysis of Yarrowia lipolytica grown with glucose (control group) and oleic acid (experimental group) as the carbon source was conducted using Illumina high-throughput sequencing and the data were analyzed by various bioinformatics methods. A total of 17 923 921 clean reads were obtained from the sequencing results of the control group, and 22 656 852 clean reads from the sequencing results of the experimental group. A total of 536 significantly differentially expressed genes were obtained between the two samples, of which 376 genes were up-regulated whereas the remaining 160 genes were down-regulated. GO and KEGG enrichment analysis showed these differential genes participated in the regulation of various biological processes. This study provides an important basis for subsequent molecular biology research.

Key words: Yarrowia lipolytica, transcriptome, differentially expressed genes
