摘要: 【目的】对两份穗伸出差异显著的大麦(Hordeum vulgare L.)材料的最上节间(UI)进行全长转录组分析,为揭示大麦UI伸长调控机制奠定基础。【方法】以包穗大麦材料CDB0012和穗伸出正常大麦品种XL19为材料,利用Nanopore平台开展了UI全长转录组测序和生物信息分析。【结果】共获得46 246条非冗余全长转录本,鉴定了2 395个潜在新基因位点和44 805条新转录本,开展了功能注释、可变剪切、差异表达基因鉴定等分析。【结论】构建了一套高质量大麦UI全长转录组数据集。

Abstract: 【Objective】 To conduct full-length transcriptome analysis of uppermost internode (UI) of two barley (Hordeum vulgare L.) accessions significantly differed by spike exsertion and build a foundation for further dissection of regulation mechanism underlying UI elongation. 【Method】 Two barley accessions,CDB00012 with sheathed spike and the Himalaya 19 (XL19) with normal spike exsertion, were used for full-length transcriptome sequencing on Nanopore platform and further bioinformatic analysis. 【Result】 A total of 46 246 unique full-length transcripts, 2 395 potential new gene loci and 44 805 new transcripts were identified, and in depth analyses, such as functional annotation, alternative splicing and differentially expressed genes, were also carried out. 【Conclusion】 Two UI high-quality full-length transcriptome datasets of barley were constructed.

Key words: barley, uppermost internode, full-length transcriptome, alternative splicing, long non-coding RNA (LncRNA)
