Project description:In this study we used single-cell type transcriptomics to identify more than 4,000 differentially expressed (DE) genes that distinguish uniplanar protonematal tip cells from multiplanar gametophore bud cells in the moss Physcomitrella patens. While the transcriptomes of both tip and bud cells harbor molecular signatures of proliferative cells, the bud cell transcriptomes exhibit a wider variety of upregulated genes. Our data suggest that the combined expression of genes regulating shoot patterning and asymmetric cell division accompanied the transition from uniplanar to triplanar meristematic growth in moss.
