ABSTRACT

Objective: To obtain the transcriptome sequence database of Melicope pteleifolia. Methods: The transcriptome sequencing and systematic bioinformatics analysis were carried out using the second generation high-throughput sequencing platform Illumina HiSeqTM 2000 with mixed root, stem and leaf samples of M. pteleifolia. Results: A total of 47 045 040 high quality sequences (clean reads) were obtained by transcriptome sequencing analysis. A total of 67 956 unigenes were assembled by Trinity de novo, with an average length of 787 nt. BLAST analysis showed that 42 749 (61.92%), 31 152 (45.84%), 26 563 (39.09%), and 17 481 (25.72%) unigenes were annotated in NR, Swiss port, KOG and KEGG databases respectively, and 47 groups were involved in three GO classification: biological process, cellular component and molecular function. A total of 9807 unigenes were annotated to 130 KEGG metabolic pathways, 19 secondary metabolic pathways were screened. Twenty-five different KOG functional groups were obtained by the analysis of KOG functional classification. It was predicted that there were 56 families of higher plant transcription factors. A total of 7 748 simple sequence repeats (SSRs) were found by MISA software. The number (4 117) of the tri-nucleotide SSRs was the richest, with a frequency of 53.1%, and the number of the penta-nucleotide SSRs was relatively small, accounting for 2.2%. Conclusion: The transcriptome information characteristics of root, stem, and leaf of M. pteleifolia can be obtained by high-throughput Illumina sequencing technology and bioinformatics analysis, which will lay a foundation for further research on functional gene mining, secondary metabolic pathway analysis and regulation mechanism of M. pteleifolia.

ABSTRACT

Melicope pteleifolia belongs to the family Rutaceae, Sect. Tetradium (Lour.) Engl. plants, which is widely distributed in Guangxi, Guangdong, Hainan, Jiangxi, Fujian, Guizhu, Yunnan, and other provinces. The main components are volatile oils and alkaloids. M. pteleifolia has been reported that it has antipyretic, analgesic, anti-inflammatory effects, and so on. In this paper, the investigation of documents, chemical components, and pharmacological effects is reviewed, which can provide a theoretical basis for further research of M. pteleifolia.
