Genome-Wide Identification and Characterization of SQUAMOSA-Promoter-Binding Protein (SBP) Genes Involved in the Flowering Development of Citrus Clementina.

ABSTRACT: SQUAMOSA-promoter binding protein (SBP)-box genes encode a family of plant-specific transcription factors that play vital roles in plant growth and development. In this study, 15 SBP-box genes were identified and isolated from Citrus clementina (CclSBPs), where 10 of these genes were predicted to be putative targets of Citrus clementina microRNA156 (CclmiR156). The 15 CclSBP genes could be classified into six groups based on phylogenetic analysis, diverse intron⁻exon structure, and motif prediction, similar to the SQUAMOSA promoter binding protein-like (SPL) gene family of Populus trichocarpa and Arabidopsis thaliana. Furthermore, CclSBPs classified into a group/subgroup have similar gene structures and conserved motifs, implying thei
