摘要： Recent advances in single-cell transcriptomics have greatly expanded our knowledge of plant development and cellular responses. However, analyzing fiber cell differentiation in plants, particularly in cotton, remains a complex challenge. A spatial transcriptomic map of ovule from -1 DPA, 0 DPA, and 1 DPA in cotton was successfully constructed, which helps to explain the important role of sucrose synthesis and lipid metabolism during early fiber development. Additionally, single-cell RNA sequencing (scRNA-seq) further highlighted the cellular heterogeneity and identified clusters of fiber developmental marker genes. Integration of spatial and scRNA-seq data unveiled key genes SVB and SVBL involved in fiber initiation, suggesting functional redundancy between them. These findings provide a detailed molecular landscape of cotton fiber development, offering valuable insights for enhancing lint yield.
