Abstract: In order to in-depth understand the overall level of transcriptome and the flavonoid biosynthesis pathway genes of Pueraria thomsonii Benth. The mixed sample of root, stem and leaf of Pueraria thomsonii was used as materials for sequencing analysis using the single-molecule long read sequencing technology(SMRT) of Pacific Biosciences Sequel platform. A total of 10 994 967 high quality reads and 384 072 full-length non-chimeric(FLNC) were obtained. Sequencing data after quality control, 90 856 isoforms were obtained. There were 85 239 isoforms annotated by NR, SwissProt, KOG, KEGG and GO databases, and the number of NR annotation was 84 675, accounting for 93.2%;In KEGG database, only 22 330 genes were annotated in 132 pathways, and 9 368 genes were distributed more in metabolic pathway, accounting for 41.95%. A total of 3 507 transcription factors(TF) were predicted, and bHLH TF family was the most annotated genes. Besides, 14 127 genes were assigned to 17 R gene classes, mainly RLP. 33 660 SSR sequences were detected, most of them were AG/CT type. By analyzing the biosynthesis pathway of flavonoids, 110 genes were found, including 26 genes encoding HCT, 3 genes encoding CHS and 7 genes encoding CHI. Compared with Illumina HiSeqTM2500, PacBio platform obtained longer transcripts and higher annotation rates. This research intensively studied the Pueraria thomsonii at the full-length transcriptome level, which provided more reliable transcriptome data for molecular biology research and scientific basis for further development of molecular markers and mining excellent genes of Pueraria thomsonii.
