Abstract:

The aim was to study the function of SBP gene family in strawberry. Various bioinformatics methods were used to analyze the phylogenesis of SBP protein sequences and the localization of SBP genome, their amino acid composition, physical and chemical characteristics, as well as secondary and tertiary structures. The result showed that these 16 amino acid sequences could be clustered into 3 groups together with 16 SBP sequences of Arabidopsis thaliana, which illuminated that SBP genes had highly conservative between strawberry and Arabidopsis thaliana. Further genetic mapping of SBP genome localization found that they could be distributed on 6 chromosomes. The research still found that the number of amino acid and hydrophobic of amino acid sequences in different subfamilies presented some differences, however, the results of secondary structure predicted that the main composition of 16 amino acid sequences was random curl and the tertiary structure of all the sequences were quite similar. SBP gene family plays great role in plant growth and development. The results of this investigation could definitely provide a significant foundation for further research on function analysis of SBP gene family in Strawberry.
