Project description:Equisetum hyemale subsp. hyemale

Project description:Members of the genus Equisetum are often referred to as “living fossils”, partly because they are the only extant representatives of the Equisetidae, a subclass that was once prominent in late Paleozoic forests. Several classes of specialized metabolites have been reported to occur in the genus Equisetum. However, while steady progress is being made with identifying individual novel metabolites of Equisetum, few if any analyses have focused on assessing the chemical diversity across the genus. The present study focused on three species: E. hyemale subsp. affine (rough horsetail or scouring rush), which is native to the temperate to artic portions of North America; E. arvense (common horsetail), which is endemic to the arctic and temperate regions of the northern hemisphere; and Equisetum telmateia subsp. braunii (Milde) Hauke (giant horsetail), which is native to western North America. Both below-ground rhizome and above-ground shoot material was harvested from each species, extracted with aqueous methanol, and subjected to non-targeted HPLC-QTOF-MS analysis. This research project was designed to lay the foundation for continued research to capture the metabolic capabilities in the ferns and fern allies.

Project description:We used phytochemical profiling techniques to generate a list of compounds present in each of 13 Equisetum arvense samples sourced globally. We used microarrays to detail the global programme of gene expression underlying the treatment of the model system Saccharomyces cerevisiae to a chosen number of these extracts. A thorough bioinformatic analysis was performed to identify the relationship between phytochemical and gene expression response profiles. We analysed 18 Equisetum arvense microarrays. Six samples were chosen from the original 13 for microarray analysis, 5 of which were performed in duplicate and the sixth in quadruplicate. Control arrays were also performed in quadruplicate.

Project description:We used LM-RNAseq to compare the molecular fingerprints of cells enriched for subdomains within Selaginella, Equisetum, Arabidopsis and maize shoot apices. Three apical domains were isolated from the Selaginella and Equisetum SAMs: the AC domain, comprising the lone AC; the core domain, comprising the cells below the AC and above the initiating leaf primordium; and the initiating leaf primordium. LM-RNAseq analyses of these shoot apical subdomains generated hundreds of significantly DEGs for each cell type relative to whole-plant transcriptomes based on an FDR ⤠0.05. These data were analyzed for the presence of homologous developmental genetic programs across these three species, and for the identification of unique developmental programs operating within each species.
