Diversity of the Pteridoflora of Montane Northwestern Mexico

open access: yesDiversity, 2023
This study compiles and updates the checklist of ferns and lycophytes from the Sierra Madre Occidental (SMOc). For this, we revised information on these taxa from regional floristic studies, databases, and herbaria. Our updated list includes 312 species,

Fossil evidence for silica biomineralization in Permian lycophytes. [PDF]

open access: yesNatl Sci Rev
This paper reports the first in-situ fossil evidence for silica biomineralisation in Permian plants. The discovery reinforces the significant role that land plants have played in influencing the evolution of Earth systems in deep time.

A Review of Galls on Ferns and Lycophytes

open access: yesEnvironmental Entomology, 2018
Fern-insect interactions have not received the same attention as angiosperm-insect interactions have. It has even been stated that ferns may have very few interactions with animals because of their lack of flowers, fruits, and seeds. Consequently, for many decades fern-insect interactions have been overlooked and underestimated, especially for highly ...

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

open access: yesPlant 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. Here we assembled a dataset of six existing and newly sampled plastid and nuclear loci with a total of 684 accessions (74% increase of the ...

Selaginella genome analysis – entering the ‘homoplasy heaven’ of the MADS world

open access: yesFrontiers in Plant Science, 2012
In flowering plants, arguably the most significant transcription factors regulating development are MADS-domain proteins, encoded by Type I and Type II MADS-box genes. Type II genes are divided into the MIKCC and MIKC* groups. In angiosperms, these types

Early Lycophyte Evolution

open access: yesAmerican Fern Journal, 2001
Lycophytes, comprising the groups historically known as the lycopsids and zosterophylls, have the longest history of any group of vascular land plants. The early evolution of the group is reviewed concentrating on the Late Silurian and Devonian record of Lycopsida and Zosterophyllopsida.

Techniques for locating and analyzing subterranean Lycopodium and Diphasiastrum gametophytes in the field

open access: yesApplications in Plant Sciences, 2022
Homosporous club mosses have an archaic life cycle, alternating two locationally, nutritionally, and physiologically independent generations. The sexual generation of club mosses—the gametophytes (or prothallia)—are among the least researched botanical ...
