Spatial transcriptomics of potato tuber initiation
Potato (Solanum tuberosum) tuber initiation represents a developmental transition from stolon elongation to radial expansion. To investigate the spatial and cellular features of this process, we generated spatial transcriptome data from stolon and early tuber tissues at two developmental stages (S1: elongating stolon; S2: swelling initiation).The dataset captures spatial gene expression patterns across multiple tissue regions, including epidermis, cortex, perimedullary region, and pith, and enables analysis of cell-type composition and spatial organization during early tuber development. This resource provides a spatial framework for studying gene expression dynamics and tissue differentiation associated with potato tuber initiation.
