Genome-wide identification, characterization, and expression patterns analysis of the SBP-box gene family in wheat (Triticum aestivum L.).

ABSTRACT: SQUAMOSA promoter-binding protein (SBP)-box genes encode a family of plant-specific transcription factors that play roles in plant growth and development. The characteristics of SBP-box genes in rice (Oryza sativa) and Arabidopsis have been reported, but their potential roles in wheat (Triticum aestivum) are not fully understood. In this study, 48 SBP-box genes (TaSBPs) were identified; they were located in all wheat chromosomes except for 4B and 4D. Six TaSBPs were identified as tandem duplication genes that formed three tandem duplication pairs, while 22 were segmentally duplicated genes that formed 16 segmental duplication pairs. Subcellular localization prediction showed TaSBPs were located in nucleus. Among the 48 TaSBPs, 24 were predicted to be putative targets of TamiR156. Phylogene
