Transcriptional analysis of Ceratopteris richardii young sporophyte reveals conservation of stem cell factors in the root apical meristem

Project description:To generate a de novo transcriptome assembly from three different parts of the Ceratopteris richardii young sporophyte (Hn-n cultivar). We then performed a differential gene expression analysis between the different plant segments, while trying to understand the expressed genes for each Ceratopteris part.

The plant hormone auxin triggers distinct phosphorylation responses in the two different generations of the fern Ceratopteris richardii

Project description:The fern Ceratopteris richardii has two distinct generations: the haploid gametophyte and diploid sporophyte, which resembles the difference between the major land plant clades of bryophytes and tracheophytes. We profiled the fast auxin-dependent phosphorylation response in both generations to identify the shared evolutionary targets and differences between the two generations

Transcriptional analysis of <i>Ceratopteris richardii</i> young sporophyte reveals conservation of stem cell factors in the root apical meristem.

Project description:Gene expression in roots has been assessed in different plant species in studies ranging from complete organs to specific cell layers, and more recently at the single cell level. While certain genes or functional categories are expressed in the root of all or most plant species, lineage-specific genes have also been discovered. An increasing amount of transcriptomic data is available for angiosperms, while a limited amount of data is available for ferns, and few studies have focused on fern roots. Here, we present a de novo transcriptome assembly from three different parts of the Ceratopteris richardii young sporophyte. Differential gene expression analysis of the root tip transcriptional program showed an enrichment of functional categories related to histogenesis and cell division, indicating an active apical meristem. Analysis of a diverse set of orthologous genes revealed conserved expression in the root meristem, suggesting a preserved role for different developmental roles in this tissue, including stem cell maintenance. The reconstruction of evolutionary trajectories for ground tissue specification genes suggests a high degree of conservation in vascular plants, but not for genes involved in root cap development, showing that certain genes are absent in Ceratopteris or have intricate evolutionary paths difficult to track. Overall, our results suggest different processes of conservation and divergence of genes involved in root development.
