Plastid Phylogenomics and Plastomic Diversity of the Extant Lycophytes

Genes, 2022
Although extant lycophytes represent the most ancient surviving lineage of early vascular plants, their plastomic diversity has long been neglected. The ancient evolutionary history and distinct genetic diversity patterns of the three lycophyte families, each with its own characteristics, provide an ideal opportunity to investigate the interfamilial ...

Chemical constituents and biological activities of lycophytes and ferns

Chinese Journal of Natural Medicines, 2019
Lycophytes and ferns are unique and charismatic members of many terrestrial ecosystems and occupy the pivotal position in land plant origin and evolution. The Chinese lycophytes and ferns flora, with approximately 2000 species, contributes a substantial component to the global lycophytes and ferns diversity, with estimates of 12 000 species. Among them,

The Carboniferous Gondwanan Lycophyte Bumbudendron, Revisited

Geobios, 2023
The type material of Bumbudendron is reviewed in the light of current knowledge about fossil lycophytes. The bark is characterized having cushions with an infrafoliar bladder and a ligule. The variation in leaf bases and leaf scars and their presence may not only depend on the plant’s age or position on the stem, but also the plant’s preservation.

Lycophytes, Ferns, and Gymnosperms

2015
This chapter surveys the diversity of living tracheophytes, clarifying the term tracheo. This term refers to the presence of tracheids, and the Greek root part of the word phyte means plant. The chapter also explains how tracheophytes form a well-supported monophyletic group of generally large plants with branched sporophyte axes and well-developed ...

Plastomes of Bryophytes, Lycophytes and Ferns

2012
We review current progress in our understanding of chloroplast genomes (plastomes) of liverworts, mosses, hornworts, lycophytes and monilophytes. We briefly cover some of the methods used to obtain complete nucleotide sequences of plastomes and we summarize the published sequences from the plant groups above. We explore some of the evolutionary changes

Mycorrhizal relationships in Lycophytes and Ferns

2016
Mycorrhizae, i.e., symbiotic associations between fungi and plant roots, occur in about 80% of land plant species and have been shown to benefit both the fungus (carbon uptake) and plant (nutrient and water uptake, protection against pathogenic fungi). We here provide a brief overview of the state of knowledge of mycorrhization in ferns. Only about 62%

Evolutionary Genomics of Ferns and Lycophytes

2016
Abstract Ferns and lycophytes are ubiquitous and charismatic members of many terrestrial ecosystems. Members of these lineages play key ecological roles in many of Earth's biomes and have an ancient fossil record dating back to the Devonian. Modern ferns underwent significant diversification in the Cretaceous, and the clade as a whole occupies a ...

A community‐derived classification for extant lycophytes and ferns

Journal of Systematics and Evolution, 2016
AbstractPhylogeny has long informed pteridophyte classification. As our ability to infer evolutionary trees has improved, classifications aimed at recognizing natural groups have become increasingly predictive and stable. Here, we provide a modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community ...

Paleo-phyllotaxis: Fucales, bryophytes, lycophytes and monilophytes

BioSystems
Fibonacci spiral arrangements have evolved independently in brown algae, bryophytes, in lycophytes and euphyllophytes. "Non-Fibonacci spirals" have been described in Asteroxylon mackiei from the Rhynie chert and on the rhyzomes of lycopsid fossils (stigmaria) as well as several groups of living lycophytes and euphyllophytes.
