%X The second generation Illumina HiSeq sequencing technology was used to sequence the xylem, phloem and leaves of <i>Phoebe bournei</i>, and 41 383 707, 43 343 922, 44 191 586 clean reads fragments were obtained, respectively. After transcript splicing, the total length of the sequence was 120 535 288 bp, including 383 331 contings. The contings were further assembled to obtain 151 729 Unigenes with an average length of 542 bp. The gene function of the transcriptome unigenes was annotated with the NR database. It was found to have the most similar sequence with grape(34%) and low homology with cucumber, wild strawberry and soybean(3% each). The GO function annotation showed that it can be divided into 52 branches of biological process, cell component and molecular function. Using eggNOG, it can be divided into 25 categories. The KEGG function annotation indicates that the genes involved in the transcriptome are involved. There are 176 metabolic pathways, most of the notes on ribosome and carbon metabolism are obtained. In addition, through the MISA software analysis, a total of 35 972 SSR sites were obtained. Among them, single nucleotide, dinucleotide and trinucleotide were dominant repeat types, and the number of SSR sites was 21 762(60.50%), 8 931(24.83%) and 4 924(13.69%), respectively. It laid a foundation for further research on genetics, breeding and molecular biology.
