Evolutionary heritage shapes tree distributions along an Amazon-to-Andes elevation gradient [PDF]
Understanding how evolutionary constraints shape the elevational distributions of tree lineages provides valuable insight into the future of tropical montane forests under global change.

The Complete Chloroplast Genome of Tree Fern Cyathea delgadii and Its Comparison to Other Cyatheales
Abstract The chloroplast genome of the tree fern Cyathea delgadii Pohl ex Sternb. was assembled and annotated to investigate its structure and evolution within the Cyatheales order. The genome, assembled using Flye and Megamerger, has a total size of 165,248 bp, comprising a large single-copy (LSC) region of 94,738 bp, a small single-copy (SSC)

Antheridiogen controls spatial dynamics of sex expression in naturally occurring gametophytes of the tree fern Cyathea multiflora. [PDF]
Abstract Premise Antheridiogen systems are a set of pheromonal mechanisms that control sex expression in fern gametophytes. However, antheridiogen has rarely been studied outside of the laboratory, and little is known about its function in natural settings.

Identification and characterization of BAHD hydroxycinnamoyltransferases in the fern Neoblechnum brasiliense. [PDF]
Significance Statement Nine BAHD acyltransferases have been identified and characterized in the fern Neoblechnum brasiliense transferring hydroxycinnamoyl units onto various alcohol and amine acceptor substrates. Kinetic characterization showed that shikimic and quinic acids for ester formation as well as 3‐hydroxyanthranilic acid and tryptamine for ...

Evolution of rapid blue-light response linked to explosive diversification of ferns in angiosperm forests. [PDF]
Summary Ferns appear in the fossil record some 200 Myr before angiosperms. However, as angiosperm‐dominated forest canopies emerged in the Cretaceous period there was an explosive diversification of modern (leptosporangiate) ferns, which thrived in low, blue‐enhanced light beneath angiosperm canopies.

Global Diversification Rates of Ferns Across Spatial and Climatic Gradients. [PDF]
Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

A comparison of freezer-stored DNA and herbarium tissue samples for chloroplast assembly and genome skimming. [PDF]
Abstract Premise The use of DNA from herbarium specimens is an increasingly important source for evolutionary studies in plant biology, particularly in cases where species are rare or difficult to obtain. Here we compare the utility of DNA from herbarium tissues to their freezer‐stored DNA counterparts via the Hawaiian Plant DNA Library. Methods Plants

Phenolic compounds in species of the Blechnaceae. [PDF]
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns. [PDF]
Summary Sex expression of homosporous ferns is controlled by multiple factors, one being the antheridiogen system. Antheridiogens are pheromones released by sexually mature female fern gametophytes, turning nearby asexual gametophytes precociously male. Nevertheless, not all species respond. It is still unknown how many fern species use antheridiogens,

Non‐seed plants are emerging gene sources for agriculture and insect control proteins
SUMMARY The non‐seed plants (e.g., charophyte algae, bryophytes, and ferns) have multiple human uses, but their contributions to agriculture and research have lagged behind seed plants. While sharing broadly conserved biology with seed plants and the major crops, non‐seed plants sometimes possess alternative molecular and physiological adaptations ...
