Description |
Plant stem cell niches are embedded within an organized group of dividing cells known as the meristem. The shoot apical meristem allows for reiterative development and the formation of new aerial structures throughout the life cycle of a plant. As in animals, plant stem cells possess the capacity to self-renew and at the same time to differentiate into lateral organs through transit-amplifying cells. Here, we use single-cell RNA sequencing to define a cellular taxonomy of the Arabidopsis vegetative shoot apex at the transcriptome level. We find that the shoot apex is composed of highly heterozygous cells, which can be partitioned into 7 broad populations with 23 transcriptionally distinct cell clusters. We delineate cell cycle progression and developmental trajectory of epidermal cells, vascular tissues and leaf mesophyll, and infer transcription factors and gene expression signatures associated with cell fate decisions. Moreover, the integrative analysis of the cell populations of shoot and root tissues reveals common features shared by two apical meristematic tissues. Our results thus provide a molecular definition of the cell populations comprising shoot apex, and offer an unprecedented opportunity to investigate the conserved principles underlying cell division and differentiation of multicellular organisms at single-cell resolution. |
