Abstract
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.
期刊介绍：
Publishing the best original research papers in all key areas of modern plant biology from the world"s leading laboratories, The Plant Journal provides a dynamic forum for this ever growing international research community.
Plant science research is now at the forefront of research in the biological sciences, with breakthroughs in our understanding of fundamental processes in plants matching those in other organisms. The impact of molecular genetics and the availability of model and crop species can be seen in all aspects of plant biology. For publication in The Plant Journal the research must provide a highly significant new contribution to our understanding of plants and be of general interest to the plant science community.
