Understory epiphytic pteridophytes along altitudinal gradients on opposite slopes in the Atlantic Forest

open access: yesRodriguésia, 2023
Gradual climatic changes caused by mountains’ altitudinal variation promote alterations in the structure of ecological communities. Environmental changes are also expected according to the slope’s position in relation to the sea.

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,

Evolution and expression of LEAFY genes in ferns and lycophytes

open access: yesEvoDevo, 2022
Background The LEAFY (LFY) transcription factors are present in algae and across land plants. The available expression and functional data of these genes in embryophytes suggest that LFY genes control a plethora of processes including the first zygotic ...

Root evolution at the base of the lycophyte clade: insights from an Early Devonian lycophyte [PDF]

open access: yesAnnals of Botany, 2016
The evolution of complex rooting systems during the Devonian had significant impacts on global terrestrial ecosystems and the evolution of plant body plans. However, detailed understanding of the pathways of root evolution and the architecture of early rooting systems is currently lacking.

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 ...

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 ...
