Pteridophytes as ecological indicators: an overview

open access: yesHoehnea, 2019
The pteridophytes present a great but poorly explored potential as ecological indicators (EIs), shown only in some sparse studies. Therefore, to analyze this potential, we reviewed published articles, websites, or books with pteridophytes as EIs ...

Chemical Profiling, In Silico and In Vitro Studies to Identify Potential CDK2 and mTOR Inhibitor From Selaginella inaequalifolia (Hook. & Grev.) Spring Ethanolic Extracts

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
ABSTRACT The current study is aimed to reveal the phytoprofile of Selaginella inaequalifolia (Hook. & Grev.) Spring using GC–MS and predict the drug properties, toxicity, biological properties of S. inaequalifolia ethanolic extracts (SiEE) using in silico methods and in vitro toxicity assays, namely, MTT and BSLB assay.

The small nuclear genomes of Selaginella are associated with a low rate of genome size evolution [PDF]

open access: yes, 2016
The haploid nuclear genome size (1C DNA) of vascular land plants varies over several orders of magnitude. Much of this observed diversity in genome size is due to the proliferation and deletion of transposable elements.

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.
Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

Fern spore dispersal: A methodological review and experimental field study

open access: yesApplications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract Spore dispersal is one of the most important but perhaps the least investigated and understood processes in determining the geographical distribution of fern species. After a methodological review of the aerobiology of fern spores, we examined the impact of spore characteristics and meteorological factors on their airborne dispersal.

Characteristics of the submicroscopic structure of the leaf epidermis in Hypodematium (Hypodematiaceae) from China and its taxonomic significance

open access: yesNordic Journal of Botany, Volume 2026, Issue 1, January 2026.
We carefully observed the submicroscopic structural characteristics of the hairs of the stipe, rachis, costae, fronds and indusia of 15 species of Hypodematium from China and photographed them under an anatomical microscope and scanning electron microscope (SEM).
