Evolutionary diversification and functional specialization of the OsTALE transcription factor family in rice," which systematically reveals the evolutionary trajectories and functional roles of the OsTALE gene family in stress resilience and development

This dataset supports the study titled "Evolutionary diversification and functional specialization of the OsTALE transcription factor family in rice," which systematically reveals the evolutionary trajectories and functional roles of the OsTALE gene family in stress resilience and development.【Study Background】TALE (Three-Amino-acid-Loop-Extension) transcription factors are central regulators linking plant development and environmental adaptation. However, their evolutionary dynamics and functional integration in cereal crops remain elusive. This work presents a comprehensive multi-omics atlas of the 29-member OsTALE family in rice, integrating phylogenetics, expression profiling, protein interaction networks, and functional validation.【Data Contents】The dataset includes all main and supplementary figures and tables used in the publication:Figure 1–10: Phylogenetic trees, gene structures, domain architectures, chromosomal locations, synteny maps, expression heatmaps under abiotic stresses and hormone treatments, and protein-protein interaction networks;Figure S1: Supplementary phylogenetic analysis;Table S1: Comprehensive annotation of OsTALE genes (gene ID, nomenclature, subfamily, genomic location, sequence features);Table S2: Normalized expression values (FPKM/RPKM) across tissues and stress conditions, differential expression statistics, and functional annotations.【Key Findings】- Identification of a novel "loss-and-simplify" evolutionary trajectory within the KNOX I subfamily, characterized by coordinated truncation of protein domains and regulatory UTRs;- Clear division of labor: KNOX II and BEL1-like members act as primary environmental responders, while most KNOX I genes are transcriptionally constrained, likely specializing in developmental programs;- Protein interaction networks confirm conserved KNOX-BELL dimers and reveal potential monocot-specific interactions;- Functional prioritization and experimental validation identify OsTALE1 and OsTALE13 as core convergent stress responders, and atypical OsTALE9 and OsTALE11 as active transcriptional activators.【Data Format】All data are provided in CSV and Excel formats for maximum accessibility. Column names are clearly labeled; units are standardized (e.g., FPKM for expression levels). Missing values are denoted as NA.【Usage License】This dataset is licensed under CC-BY 4.0.

本数据集支撑题为《水稻OsTALE转录因子家族的进化分化与功能特化》的研究，该研究系统揭示了OsTALE基因家族在胁迫抗性与生长发育中的进化轨迹与功能作用。【研究背景】TALE（Three-Amino-acid-Loop-Extension，三氨基酸环延伸）转录因子是连接植物发育与环境适应的核心调控因子。然而，它们在谷类作物中的进化动态与功能整合机制仍不明确。本研究构建了水稻29个成员OsTALE家族的综合多组学图谱，整合了系统发育分析、表达谱分析、蛋白质互作网络与功能验证数据。【数据内容】本数据集包含论文中使用的全部主图、附表及表格：图1~10：系统发育树、基因结构、结构域架构、染色体定位、共线性图谱、非生物胁迫与激素处理下的表达热图以及蛋白质-蛋白质互作网络；图S1：补充系统发育分析；表S1：OsTALE基因的综合注释信息（基因ID、命名规则、亚家族、基因组定位、序列特征）；表S2：各组织与胁迫条件下的标准化表达值（FPKM/RPKM）、差异表达统计数据与功能注释。【核心发现】- 鉴定出KNOX I亚家族内一种全新的“丢失与简化”进化轨迹，其特征为蛋白质结构域与调控UTR的协同截短；- 明确的功能分工：KNOX II与类BEL1成员作为主要的环境响应因子，而大多数KNOX I基因受转录约束，大概率特化于发育程序；- 蛋白质互作网络验证了保守的KNOX-BELL二聚体，并揭示了潜在的单子叶植物特异性互作；- 通过功能优先级排序与实验验证，确定OsTALE1与OsTALE13为核心的协同胁迫响应因子，非典型的OsTALE9与OsTALE11为活跃的转录激活因子。【数据格式】所有数据均以CSV与Excel格式提供，以保障最大程度的可访问性。列名均已明确标注；单位均已标准化（例如表达水平采用FPKM）。缺失值以NA表示。【使用许可】本数据集采用CC-BY 4.0许可协议。我们鼓励其在学术研究与教育领域的复用，前提是需正确引用本数据集与相关论文的DOI
