摘要:

为探究响应向日葵干旱胁迫的转录组SNP标记信息,以向日葵抗旱自交系17062为供试材料,利用RNA-seq技术结合生物信息学分析方法,对SNP标记进行统计分析。结果表明,SNP类型分析中,转换率占62.82%,颠换率占37.17%,转换中以C/T发生频率最高,为31.51%。功能原件分布中,分布在外显子区的SNP数量为178744.3个,显著多于其他功能元件。对SNP位点序列注释发现,有76678条SNP基因具有GO注释,4379条具有KEGG注释。筛选GO注释排序前30位(Top30)差异基因(DEGs)中重复存在的SNP基因序列,得到1542条,其中650条基因序列有GO注释。这些差异基因涉及到了多个生物功能与重要代谢途径,对向日葵转录组SNP标记开发、向日葵抗旱种质资源鉴定及抗旱“三系”杂交种选育具有重要意义。

Abstract:

In order to explore the transcriptome SNP markers in response to drought stress in sunflower, with the sunflower drought resistant inbred line 17062 as the experimental material, RNA-seq technology combined with bioinformatics analysis method was used to statistically analyze SNP markers. The results showed that in SNP type analysis, the conversion rate accounted for 62.82%, and the inversion rate accounted for 37.17%. In the conversion, the frequency of C/T was the highest, which was 31.51%. In the distribution of functional elements, the number of SNP distributed in exons was 178744.3, which was significantly more than that of other functional elements. The sequence annotation of SNP sites found that 76678 SNP genes had GO annotation and 4379 had KEGG annotation. The repeated SNP gene sequences in the Top30 GO annotation ranking (Top30) differential genes (DEGs) were screened, and 1542 genes were obtained, of which 650 gene sequences had GO annotation. These differential genes are involved in multiple biological functions and important metabolic pathways, which are of great significance for the development of SNP markers in sunflower transcriptome, the identification of drought resistant germplasm resources, and the selection of drought resistant “three-line” hybrids.
