Anatomically preserved early Cretaceous lycophyte shoots; enriching the paleontological record of Lycopodiales and Selaginellales

Acta Palaeobotanica, 2023
Anatomically preserved lycophytes of the Lycopodiales and Selaginellales have been discovered among a diverse assemblage of plants and fungi in carbonate marine concretions at the Apple Bay locality along the shore of Holbert Inlet near the northern end ...

Is There a Key Primer for Amplification of Core Land Plant DNA Barcode Regions (rbcL and matK)? [PDF]

Ecol Evol
We use in silico PCR to select and measure the amplification capability of primer. We tested 366 and 489 published primers for the rbcL and matK regions, respectively, using sequences from 8463 different land plant species. Our results indicate a set of primers that effectively cover all land plant sequences, particularly for the rbcL region.

Phylogeny, character evolution, and classification of Selaginellaceae (lycophytes)

Plant Diversity, 2023
Selaginella is the largest and most taxonomically complex genus in lycophytes. The fact that over 750 species are currently treated in a single genus makes Selaginellales/Selaginellaceae unique in pteridophytes.

Evolution of the jasmonate ligands and their biosynthetic pathways

New Phytologist, Volume 238, Issue 5, Page 2236-2246, June 2023., 2023
Summary Different plant species employ different jasmonates to activate a conserved signalling pathway in land plants, where (+)‐7‐iso‐JA‐Ile (JA‐Ile) is the ligand for the COI1/JAZ receptor in angiosperms and dn‐cis‐OPDA, dn‐iso‐OPDA and Δ4‐dn‐iso‐OPDA act as ligands in Marchantia polymorpha.

What can lycophytes teach us about plant evolution and development? Modern perspectives on an ancient lineage

Evolution &Development, Volume 23, Issue 3, Page 174-196, May 2021., 2021
As the earliest diverging group of extant vascular plants, lycophytes are important for determining how traits such as branching, vasculature, shoot indeterminacy, leaves, and roots evolved. In this review, we describe lycophyte phylogeny, morphology, and genetics in the context of land plant evolution and development.

Evolution of rapid blue‐light response linked to explosive diversification of ferns in angiosperm forests

New Phytologist, Volume 230, Issue 3, Page 1201-1213, May 2021., 2021
Summary Ferns appear in the fossil record some 200 Myr before angiosperms. However, as angiosperm‐dominated forest canopies emerged in the Cretaceous period there was an explosive diversification of modern (leptosporangiate) ferns, which thrived in low, blue‐enhanced light beneath angiosperm canopies.

Convergent evolution of the UbiA prenyltransferase family underlies the independent acquisition of furanocoumarins in plants

New Phytologist, Volume 225, Issue 5, Page 2166-2182, March 2020., 2020
Summary Furanocoumarins (FCs) are plant‐specialized metabolites with potent allelochemical properties. The distribution of FCs is scattered with a chemotaxonomical tendency towards four distant families with highly similar FC pathways. The mechanism by which this pathway emerged and spread in plants has not been elucidated.

Towards a plant model for enigmatic U‐to‐C RNA editing: the organelle genomes, transcriptomes, editomes and candidate RNA editing factors in the hornwort Anthoceros agrestis

New Phytologist, Volume 225, Issue 5, Page 1974-1992, March 2020., 2020
Summary Hornworts are crucial to understand the phylogeny of early land plants. The emergence of ‘reverse’ U‐to‐C RNA editing accompanying the widespread C‐to‐U RNA editing in plant chloroplasts and mitochondria may be a molecular synapomorphy of a hornwort–tracheophyte clade.
