The genus Selaginella P. BEAUV. (Selaginellaceae, Lycopodiopsida) in Poland: The occurrence of three species as a result of the historical material verification

Acta Societatis Botanicorum Poloniae, 2023
Two species of the Selaginella genus were noted in Poland up to date, i.e. S. selaginoides and S. helvetica . The first species occurs in the Western Carpathians and the Western Sudetes, however, its Sudeten sites were less numerous than previously ...

Directed Repeats Co-occur with Few Short-Dispersed Repeats in Plastid Genome of a Spikemoss, Selaginella vardei (Selaginellaceae, Lycopodiopsida) [PDF]

BMC Genomics, 2019
Background It is hypothesized that the highly conserved inverted repeats (IR) structure of land plant plastid genomes (plastomes) is beneficial for stabilizing plastome organization, whereas the mechanism of the occurrence and stability maintenance of ...

PWO proteins are associated with PRC2 since their emergence in vascular plants. [PDF]

New Phytol
Summary The Polycomb repressive complex 2 (PRC2), a conserved histone methyltransferase complex, plays a central role in transcriptional silencing across eukaryotes. Here, we investigate the evolution of PWWP‐DOMAIN INTERACTORS OF POLYCOMBS (PWOs), which interact with PRC2, and examine the conservation of the PWOs‐PRC2 interaction across plant ...

Isoëtes sabatina (Isoëtaceae, Lycopodiopsida): Taxonomic distinctness and preliminary ecological insights [PDF]

Aquatic Conservation: Marine and Freshwater Ecosystems, 2021
Abstract Isoëtes sabatina is the rarest aquatic quillwort in Europe. Although recently found (2013) in Lake Bracciano (central Italy), the species is just one step away from extinction with an estimated population not exceeding 400 individuals and a spatial range of a few hundred square metres. Lake Bracciano is a deep, oligo‐mesotrophic Mediterranean

Phenolic compounds in species of the Blechnaceae. [PDF]

Plant Biol (Stuttg)
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

Proliferation of Isoëtalean Lycophytes During the Permo-Triassic Biotic Crises: A Proxy for the State of the Terrestrial Biosphere

Frontiers in Earth Science, 2021
Throughout their 420-Ma-long history, Lycopodiopsida have played a subordinate role at the landscape level with very few exceptions. One being the arborescent Lepidodendrales that dominated Pennsylvanian peat swamps in equatorial regions.

The PteridoPortal: A publicly accessible collection of over three million records of extant and extinct pteridophytes. [PDF]

Appl Plant Sci
Abstract Premise Pteridophytes—vascular land plants that disperse by spores—are a powerful system for studying plant evolution, particularly with respect to the impact of abiotic factors on evolutionary trajectories through deep time. However, our ability to use pteridophytes to investigate such questions—or to capitalize on the ecological and ...

The trehalose 6‐phosphate phosphatase family in plants

Physiologia Plantarum, Volume 175, Issue 6, November/December 2023., 2023
Abstract Trehalose 6‐phosphate (Tre6P), the intermediate of trehalose biosynthesis, is an essential signalling metabolite linking plant growth and development to carbon metabolism. While recent work has focused predominantly on the enzymes that produce Tre6P, little is known about the proteins that catalyse its degradation, the trehalose 6‐phosphate ...

Non‐seed plants are emerging gene sources for agriculture and insect control proteins

The Plant Journal, Volume 116, Issue 1, Page 23-37, October 2023., 2023
SUMMARY The non‐seed plants (e.g., charophyte algae, bryophytes, and ferns) have multiple human uses, but their contributions to agriculture and research have lagged behind seed plants. While sharing broadly conserved biology with seed plants and the major crops, non‐seed plants sometimes possess alternative molecular and physiological adaptations ...

Using eDNA metabarcoding to understand the effect of fire on the diet of small mammals in a woodland ecosystem

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022
Information regarding diet changes over time after disturbance is lacking for many animals living in habitats prone to disturbances such as fires. DNA metabarcoding is a versatile molecular method that allows simultaneous characterization of many biotas using taxonomically informative barcode regions.
