摘要: 为了研究文冠果果实转录组中功能基因表达情况,采样RNA-seq技术对文冠果不同发育时期果实进行测序分析。结果显示:两个时期样品材料测序组装后共获得68 298个Unigene序列,有24 691个Unigene得到注释,占36.15%;GO数据库注释显示14 766条Unigene分为细胞组分、分子功能及生物学过程3大类54个功能组;KOG数据库中注释到的13 994条Unigene功能系统分为25类;以KEGG代谢途径数据库为依据,可将8 284个文冠果果实转录组Unigene分为127个代谢通路;在文冠果果实转录组中发现11 732个SSR位点,其中最多的为单核苷酸SSR,占60.85%。本研究为文冠果果实分子生物学研究提供了一定的基础和参考。

Abstract: In order to study the expressions of functional genes in the transcriptome of Xanthoceras sorbifolia Bunge fruit,the RNA-Seq technology was used to sequence Xanthoceras sorbifolia Bunge fruit in different stag. The sequencing results showed that a total of 68 298 Unigene sequences after sequencing and assembly were obtained from the samples in 2 stages,and 24 691 Unigene sequences were annotated,accounting for 36.15%. Based on GO database,the 14 766 Unigene sequences were divided into 3 categories of cellular component,molecular function and biological process and 54 function groups. The 13 994 Unigene sequences were grouped into 25 functional categories based on KOG database. Based on KEGG metabolic pathway database,8 284 Unigene sequences of X. sorbifolia Bunge fruit may be classified into 127 metabolic pathways. And 11 732 SSR(Simple Sequence Repeats)loci were discovered in X. sorbifolia Bunge fruit transcriptome. Most of them were single nucleotide SSR,accounting for 60.85%. This study provides the foundation and reference for molecular biology study in X.sorbifolia Bunge fruit.
