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.
