Revisiting Ancient Polyploidy in Leptosporangiate Ferns [PDF]

open access: yesbioRxiv, 2022
Ferns, and particularly homosporous ferns, have long been assumed to have experienced recurrent whole-genome duplication (WGD) events because of their substantially large genome sizes, surprisingly high chromosome numbers, and high degrees of polyploidy ...

Germination fitness of two temperate epiphytic ferns shifts under increasing temperatures and forest fragmentation. [PDF]

open access: yesPLoS ONE, 2018
Ferns are an important component of ecosystems around the world. Studies of the impacts that global changes may have on ferns are scarce, yet emerging studies indicate that some species may be particularly sensitive to climate change.

Exploring the phylogeny of the marattialean ferns [PDF]

open access: yesCladistics, 2020
The eusporangiate marattialean ferns represent an ancient radiation with a rich fossil record but limited modern diversity in the tropics. The long evolutionary history without close extant relatives has confounded studies of the phylogenetic origin ...

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 ...

Fern Habitats and Rare Ferns in Oklahoma [PDF]

open access: yesOklahoma Native Plant Record, 2008
This paper features some of the more common fern habitats in Oklahoma and provides information on four rare Oklahoma ferns from two fern families: Aspleniaceae and Pteridaceae. Surprisingly, ferns can be found in a variety of habitats across Oklahoma.

Natural Area Weeds: Distinguishing Native and Non-Native "Boston Ferns" and "Sword Ferns" (Nephrolepis spp.) [PDF]

open access: yesEDIS, 2017
The proliferation of non-native Nephrolepis fern species in Florida's natural areas poses a significant challenge for distinguishing them from native sword ferns (Nephrolepis exaltata) and giant sword ferns (Nephrolepis biserrata).

Evolution of stomatal closure to optimise water use efficiency in response to dehydration in ferns and seed plants.

open access: yesNew Phytologist, 2021
Plants control water use efficiency (WUE) by regulating water loss and CO2 diffusion through stomata. Variation in stomatal control has been reported among lineages of vascular plants, thus giving raise to the possibility that different lineages may show

Phylotranscriptomics Illuminates the Placement of Whole Genome Duplications and Gene Retention in Ferns

open access: yesFrontiers in Plant Science, 2022
Ferns are the second largest clade of vascular plants with over 10,000 species, yet the generation of genomic resources for the group has lagged behind other major clades of plants.

Change in β-glucosidase activity in root zone of ferns under toxic elements soil contamination [PDF]

open access: yes, 2023
The influence of toxic elements, such as arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn), in the root zone of As-hyperaccumulator Pteris cretica 'Albo-lineata' and non-As-hyperaccumulator P.

Evolution of genome space occupation in ferns: linking genome diversity and species richness

open access: yesAnnals of Botany, 2021
Background and Aims The dynamics of genome evolution caused by whole genome duplications and other processes are hypothesized to shape the diversification of plants and thus contribute to the astonishing variation in species richness among the main ...
