Genome-Wide Characterization and Expression Analysis of the SBP-Box Gene Family in Sweet Orange (Citrus sinensis).

ABSTRACT: SBP-box is an important plant-specific transcription factor family and is involved in diverse biological processes. Here, we identified a total of 15 SBP-BOX genes in the important fruit crop sweet orange (Citrus sinensis) and characterized their gene structures, conserved domain and motif, chromosomal location, and cis-acting regulatory elements. SBP genes were classified into four subfamilies based on the amino acid sequence homology, and the classification is equally strongly supported by the gene and protein structures. Our analysis revealed that segmental duplication events were the main driving force in the evolution of CsSBP genes, and gene pairs might undergo extensive purifying selection. Further synteny analysis of the SBP members among sweet or
