YABBY is a plant-specific transcription factor (TF) that belongs to the zinc finger protein superfamily and is composed of a C2-C2 domain at the N-terminus and a YABBY domain at the C-terminus. It plays a role in plant development and growth.
In this study, 20 YABBY TFs were identified in the wheat genome. Phylogenetic relationships, collinearity relationships, gene structures, conserved motifs, and expression patterns were analyzed.
Twenty TaYABBY TFs were distributed unevenly on 15 chromosomes. Collinearity analysis showed that these genes have a close relationship with monocot plants. The phylogenetic tree of wheat YABBYs classified these TaYABBYs into FIL, YAB2, INO, and CRC clades. Gene structure and conserved motif analyses showed that they share similar components in the same clades. Expression profile analysis showed that many TaYABBY genes have high expression levels in leaf tissues and are regulated by abiotic stresses, especially salt stress. Our results provide a basis for further functional characterization of the YABBY gene family.
YABBY 是一种植物特异性转录因子（TF），属于锌指蛋白超家族，由 N 端的 C2-C2 结构域和 C 端的 YABBY 结构域组成。它在植物发育和生长中发挥作用。
本研究在小麦基因组中鉴定出 20 个 YABBY TF。分析了系统发育关系、共线性关系、基因结构、保守基序和表达模式。
20 个 TaYABBY TF 不均匀分布在 15 条染色体上。共线性分析表明，这些基因与单子叶植物密切相关。小麦 YABBY 的系统发育树将这些 TaYABBY 分为 FIL、YAB2、INO 和 CRC 分支。基因结构和保守基序分析表明，它们在同一分支中具有相似的组成部分。表达谱分析表明，许多 TaYABBY 基因在叶片组织中具有高表达水平，并受非生物胁迫的调控，特别是盐胁迫。我们的结果为 YABBY 基因家族的进一步功能特征提供了依据。
