Genome size evolution of the extant lycophytes and ferns

open access: yesPlant Diversity, 2022
Ferns and lycophytes have remarkably large genomes. However, little is known about how their genome size evolved in fern lineages. To explore the origins and evolution of chromosome numbers and genome size in ferns, we used flow cytometry to measure the ...

Ferns and lycophytes in Brazil's semi-arid region [PDF]

open access: yesRodriguésia, 2012
Little knowledge has been gathered on ferns and lycophytes occurring in the semi-arid region of Brazil known as the Caatinga, perhaps due to the widespread idea that a semi-arid climate would be incompatible with environmental demands of ferns and ...

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency? [PDF]

open access: yesNew Phytol
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

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.

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 ...

Arbuscular mycorrhizal and dark septate fungi are not common in roots of epiphytic pteridophytes of a transitional forest area in South Brazil

open access: yesActa Botânica Brasílica, 2022
Arbuscular mycorrhizal fungi (AMF) and dark septate fungi (DSF) are symbionts that are associated with the roots of plants, including epiphytic lycophytes and ferns.

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 ...

NCP activates chloroplast transcription by controlling phytochrome-dependent dual nuclear and plastidial switches. [PDF]

open access: yes, 2019
Phytochromes initiate chloroplast biogenesis by activating genes encoding the photosynthetic apparatus, including photosynthesis-associated plastid-encoded genes (PhAPGs).
