小麦（Triticum aestivum L.）是世界上最重要的农作物之一。鳞状细胞启动子结合蛋白（SBP）盒基因在调控花和果实发育中起着关键作用。本研究从小麦（Triticum aestivum L.）品种烟占4110）。系统发育分析将TaSPL基因分为5个类群（G1-G5）。TaSPL基因的基序组合和表达模式在5个群体中各有特点：G1期的TaSPL 20/21和G2期的TaSPL 17主要在茎尖分生组织和幼穗中表达，其表达水平与幼穗的发育有关;在籽粒发育过程中，属于G3的TaSPL 6/15表达上调，G4的TaSPL 1/23表达下调，G5的TaSPL 3基因组成型表达。因此，TaSPL基因的系统发育分析，基序组成和表达模式的一致性揭示了特定的基因结构和功能。另一方面，小麦SBP-box基因多样的基因结构和不同的表达模式表明其具有广泛的功能。研究结果还表明，小麦SBP-box基因在穗发育中的潜在作用。本研究为小麦SBP-box基因的功能分析提供了一个重要的开端。
Wheat (Triticum aestivum L.) is one of the most important crops in the world. Squamosa-promoter binding protein (SBP)-box genes play a critical role in regulating flower and fruit development. In this study, 10 novel SBP-box genes (TaSPL genes) were isolated from wheat ((Triticum aestivum L.) cultivar Yanzhan 4110). Phylogenetic analysis classified the TaSPL genes into five groups (G1–G5). The motif combinations and expression patterns of the TaSPL genes varied among the five groups with each having own distinctive characteristics: TaSPL20/21 in G1 and TaSPL17 in G2 mainly expressed in the shoot apical meristem and the young ear, and their expression levels responded to development of the ear; TaSPL6/15 belonging to G3 were upregulated and TaSPL1/23 in G4 were downregulated during grain development; the gene in G5 (TaSPL3) expressed constitutively. Thus, the consistency of the phylogenetic analysis, motif compositions, and expression patterns of the TaSPL genes revealed specific gene structures and functions. On the other hand, the diverse gene structures and different expression patterns suggested that wheat SBP-box genes have a wide range of functions. The results also suggest a potential role for wheat SBP-box genes in ear development. This study provides a significant beginning of functional analysis of SBP-box genes in wheat.
