The plant phosphatidylethanolamine-binding protein (PEBP) genes play an important role in controlling flowering time. Rapeseed, as one of the most important oil crops in the world, has similar flowering habits with Arabidopsis thaliana. In this study, the PEBP family protein sequences of A. thaliana were used to perform BlastP analysis in the rapeseed genome. The members of the rape PEBP family were obtained, and the gene structure analysis, motif prediction, duplication analysis, phylogenetic tree construction, selective pressure analysis and tissue expression analysis were carried out on the family members. A total of 26 rapeseed PEBP gene members were identified, and most of them contained four exons and three introns, and motif-1 and motif-2 were the characteristics of PEBP members. Over 76.9% members were segmental duplicated. Phylogenetic tree analysis showed that PEBP was divided into three subfamilies. The tissue-specifics analysis based on RNA-Seq data showed that 26 PEBP members of rapeseed had very obvious tissue expression characteristics. All these results greatly enrich our understandings of flowering genes and regulation patterns in Brassica napus, and provide a theoretical basis for further molecular breeding in B. napus.
