De novo transcriptome assembly of two different peach cultivars grown in Korea

Peach (Prunus persica) is one of the most popular stone fruits worldwide. Next generation sequencing (NGS) has facilitated genome and transcriptome analyses of several stone fruit trees. In this study, we conducted de novo transcriptome analyses of two peach cultivars grown in Korea. Leaves of two cultivars, referred to as Jangtaek and Mibaek, were harvested and used for library preparation. The two prepared libraries were paired-end sequenced by the HiSeq2000 system. We obtained 8.14 GB and 9.62 GB sequence data from Jangtaek and Mibaek (NCBI accession numbers: SRS1056585 and SRS1056587), respectively. The Trinity program was used to assemble two transcriptomes de novo, resulting in 110,477 (Jangtaek) and 136,196 (Mibaek) transcripts. TransDecoder identified possible coding regions in assembled transcripts. The identified proteins were subjected to BLASTP search against NCBI's non-redundant database for functional annotation. This study provides transcriptome data for two peach cultivars, which might be useful for genetic marker development and comparative transcriptome analyses.
