Genome-wide Identification and Bioinformatics Analysis of the Sugar Beet Small G Protein BvRab Gene Family
[Objective]Members of the BvRab gene family on the genome-wide screening were identified,which laid the foundation for the study of the function of the BvRab gene family in sugar beet.[Methods]In this study,bioinformatic methods were used to perform genome-wide screening and identification of the BvRab gene family in sugar beet,followed by analysis of their physicochemical properties,gene structure,protein conserved motifs,phylogenetic evolution,chromosome localization and collinearity,promoter cis-acting elements and protein-protein interaction prediction.[Results]A total of 58 members of the BvRab gene family of small G proteins in sugar beet were identified.The results showed that different genes within the same type had relatively consistent exon and intron structures,and there were 5 conserved motifs in the BvRab family proteins.A total of 8 subfamilies were identified in the BvRab gene family of small GTP-binding proteins.The family members were unevenly distributed on the 9 chromosomes of sugar beet.The BvRab gene family members were closely related to the Rab gene family in tomato and Arabidopsis thaliana,while far from the Rab gene family in rice.The promoter of BvRab gene family contained multiple hormonal response elements and abiotic response elements.BvRab proteins interacted with various transcription factors involved in plant growth and development as well as stress response.[Conclusion]Fifty-eight members of the BvRab gene family in sugar beet were identified in this study,which may play important roles in plant growth and development as well as in response to adversity.
