Physcomitrella patens cultivar:Gransden Transcriptome or Gene expression

ABSTRACT: 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.

Haploid moss gametophytes harbor distinct stem cell types, including tip cells that divide in single planes to generate filamentous protonemata, and bud cells that divide in three planes to yield axial gametophore shoots. This transition from filamentous to triplanar growth occurs progressively during the moss life cycle, and is thought to mirror evolution of the first terrestrial plants from Charophycean green algal ancestors. The innovation of morphologically complex plant body plans facilitat  ...[more]
