Project description:Toona sinensis, a medicinal and edible plant, holds economic and ecological significance in Asia. Despite its diverse applications, the genetic basis of leaf color formation remains unclear. This study aimed to investigate the molecular mechanisms underlying color variations across three cultivars (red, brown, green) at different developmental stages. Young tender leaflets from apical tips and fully expanded leaflets from basal positions of the same compound leaf were collected for RNA-Seq analysis.
Project description:Understanding the regulation of bud dormancy–activity transition is critical for annual bud production and high-quality cultivation of Toona sinensis. 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.
