Here, we report a comparative transcriptomic analysis of dormant and actively growing buds. Transcriptome profiling identified 3,779 differentially expressed genes (DEGs), which were significantly enriched in key pathways such as ribosome, photosynthesis-antenna proteins, plant hormone signal transduction, and MAPK signaling pathway. Additionally, 327 DEGs were classified as transcription factors (TFs) belonging to 48 families, including NAC, AP2/ERF, MYB-related, bZIP, and WRKY. Our data provide a molecular framework for understanding the integrated regulatory network involving phytohormone signaling, ribosome biogenesis, photosynthetic activity, and transcription factor cascades that governs bud dormancy–activity transition in Toona sinensis.2026/08/21GSE343664GSM9959439GSM9959438GSM9959435GSM9959434GSM9959437GSM995943637367343664Toona sinensis
