SQUAMOSA promoter binding protein (SBP), as a plant-specific transcription factor, plays an important role in plant growth development. In this study, 15 SBP genes were identified from the cucumber genome by bioinformatics methods, and the physicochemical property, gene structure, phylogeny, and expression of these genes in different tissues were analyzed. The results showed that 15 genes were distributed on 4 chromosomes, and divided into 6 groups. Genes in the same group had similar structure and conservative motifs. Expression analysis shows CsSBP9, CsSBP12, CsSBP10, CsSBP3, CsSBP8 and CsSBP7 are expressed in all tissues, and the other genes are expressed in specific tissues, suggesting that SBP genes play an important role in the growth development of cucumber at different stages. This study lays a foundation for the further identification of cucumber SBP gene function.
