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 ...

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

open access: yesEvolution & Development, 2020
All Evo‐Devo studies rely on representative sampling across the tree of interest to elucidate evolutionary trajectories through time. In land plants, genetic resources are well established in model species representing lineages including bryophytes ...

Methodologies for soil extraction and conservation analysis of ferns and lycophytes with belowground gametophytes

open access: yesApplications in Plant Sciences, 2022
Premise Studies of fern and lycophyte gametophyte biology in natural settings can be challenging, but such analyses are critical to understanding the dispersal, ecology, and conservation of these species.

Diversity and distribution of ferns and lycophytes in areas of restinga sandy coastal plain in south of Santa Catarina, Brazil

open access: yesRodriguésia, 2023
Ferns and lycophytes are plants often overlooked in most floristic inventories, leading to considerable gaps in the knowledge of their diversity and geographic distribution. To address this issue, we conducted a study aimed at reducing these gaps for the

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

open access: yesFrontiers 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.

A lycophyte's plight when the light is too bright

open access: yesPhysiologia Plantarum, 2022
Plants cannot go to the store to buy sunscreen when they get too much sunlight. Instead, they use a suite of molecular processes that turn excess absorbed light energy into heat so that it can be harmlessly dissipated. These photoprotective processes collectively fall under the umbrella term “nonphotochemical quenching of chlorophyll fluorescence ...
