High-throughput Transcriptome Identification and Flavonoids Metabolic Pathways in Nitraria sphaerocarpa

  • Received Date: 2015-07-06
  • [Objective]To understand the biosynthetic pathway of flavonoids and its roles in the adaptation to abiotic stresses in Nitraria sphaerocarpa. [Method]High-throughput RNA-seq technology was used to generate the transcriptome of current-year leaves, and then the related bioinformatics analysis was performed. [Result]The results showed that 13 013 444 raw reads and 48 921 unigenes were acquired after de novo assembly; 30 407 annotations were acquired from Nr database, 19 671 from Swiss-Prot database, 9 273 from COG database, 46 153 from GO database and 13 654 from KEGG database after function annotation against five databases; 186 unigenes were associated with flavonoid biosynthesisby the analysis of KEGG pathway. [Conclusion]The better transcriptomic data was obtained, and it was rich in the genes involved in flavonoids biosynthesis, which would provide references for the studies of its resistance, medicinal value in future.
