Sedimentary ancient DNA from Lake Skartjorna, Svalbard: assessing the resilience of arctic flora to Holocene climate change [PDF]

, 2015
Reconstructing past vegetation and species diversity from arctic lake sediments can be challenging because of low pollen and plant macrofossil concentrations. Information may be enhanced by metabarcoding of sedimentary ancient DNA (sedaDNA). We developed

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

Journal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Complete plastid genomes from Ophioglossum californicum, Psilotum nudum, and Equisetum hyemale reveal an ancestral land plant genome structure and resolve the position of Equisetales among monilophytes [PDF]

, 2013
BACKGROUND: Plastid genome structure and content is remarkably conserved in land plants. This widespread conservation has facilitated taxon-rich phylogenetic analyses that have resolved organismal relationships among many land plant groups.

RNA-seq of aboveground sporophyte’s transcriptome of Huperzia serrata and transcriptional understanding of early steps associated with huperzine biosynthesis in forest

Current Plant Biology, 2020
Chinese toothed clubmoss (Huperzia serrata) is a primitive fern native in certain types of forests. It is severely endangered in China due to its difficult propagation and massive hunting for huperzine A to improve and prevent Alzheimer’s disease.
