Molecular characterization of SBP-box gene family during floral induction in walnut (Juglans regia L.)

SQUAMOSA promoter-binding protein (SBP)-box genes regulate plant-specific transcription factors that play vital roles in diverse biological processes. In this study, we identified 48 SBP-box genes from Juglans regia ( JrSBPs ) based on the transcriptome dataset. Nineteen of these JrSBP s were predic...

Zusammenfassung:SQUAMOSA promoter-binding protein (SBP)-box genes regulate plant-specific transcription factors that play vital roles in diverse biological processes. In this study, we identified 48 SBP-box genes from Juglans regia ( JrSBPs ) based on the transcriptome dataset. Nineteen of these JrSBP s were predicted to be putative target genes of jre-miR156/157 . Phylogenetic tree based on the conserved SBP domains divided the JrSBP s into nine groups, analogous to those from Arabidopsis . JrSBP members within the same group shared similar motifs. Cis-elements analysis implied that JrSBP genes were regulated by light, phytohormones, and stresses. Functions of JrSBP genes were predicted and analyzed by comparing the proteins of JrSBP s and SPL s from Arabidopsis . Expression profile of JrSBP s was analyzed based on RNA-seq and RT-qPCR. The results should provide fundamental information for understanding the roles of JrSBP s during floral induction.
