SQUAMOSA启动子结合蛋白（SBP）盒基因编码一个植物特异性转录因子家族，在植物生长发育中发挥作用。水稻和拟南芥中SBP-box基因的特性已被报道，但它们在小麦中的潜在作用还不完全清楚。在这项研究中，48 SBP-box基因（TaSBPs）的鉴定，他们被定位在所有的小麦染色体上，除了4 B和4D。6个TaSBPs被鉴定为串联重复基因，形成3个串联重复对，而22个片段重复基因，形成16个片段重复对。亚细胞定位预测显示TaSBPs定位于细胞核。在48个TaSBP中，24个被预测为TamiR 156的推定靶点。系统发育分析表明，功能相似的TaSBPs、AtSBPs和OsSBPs聚为同一亚群。高度保守的基序和基因结构的鉴定支持TaSBPs之间的系统发育关系。四种类型的顺式元件-转录相关的，发育相关的，死亡相关的，和非生物胁迫相关的元件-被发现在TaSBP启动子。表达谱表明大多数TaSBPs参与花发育和非生物胁迫响应。本研究为进一步研究TaSBP基因奠定了基础，并为深入了解其生物学功能提供了新的视角。
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. Phylogenetic analysis showed that TaSBPs, AtSBPs, and OsSBPs that shared similar functions were clustered into the same subgroups. The phylogenetic relationships between the TaSBPs were supported by the identification of highly conserved motifs and gene structures. Four types of cis-elements––transcription-related, development-related, hormone-related, and abiotic stress-related elements––were found in the TaSBP promoters. Expression profiles indicated most TaSBPs participate in flower development and abiotic stress responses. This study establishes a foundation for further investigation of TaSBP genes and provides novel insights into their biological functions.
