A new, simple, highly scalable, and efficient protocol for genomic DNA extraction from diverse plant taxa. [PDF]

Appl Plant Sci, 2021
Premise Commonly used molecular techniques such as next‐generation sequencing require reliable methods to extract DNA quickly and efficiently. Secondary compounds within plant tissues make this requirement all the more challenging, often forcing researchers to test different extraction methods tailored to their particular species of interest in order ...

Evolution of rapid blue-light response linked to explosive diversification of ferns in angiosperm forests. [PDF]

New Phytol, 2021
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]

Adv Sci (Weinh)
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 ...

Transcriptome-wide SNPs for Botrychium lunaria ferns enable fine-grained analysis of ploidy and population structure. [PDF]

Mol Ecol Resour, 2022
Abstract Ferns are the second most diverse group of land plants after angiosperms. Extant species occupy a wide range of habitats and contribute significantly to ecosystem functioning. Despite the importance of ferns, most taxa are poorly covered by genomic resources and within‐species studies based on high‐resolution markers are entirely lacking.

An efficient and effective RNA extraction protocol for ferns. [PDF]

Appl Plant Sci
Abstract Premise The extraction of high‐quality RNA is the critical first step for the analysis of gene expression and gene space. This remains particularly challenging in plants, and especially in ferns, where the disruption of the cell wall and separation of organic compounds from nucleic acids is not trivial.

Non‐seed plants are emerging gene sources for agriculture and insect control proteins

The Plant Journal, Volume 116, Issue 1, Page 23-37, October 2023., 2023
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 ...

First report of silicified wood from a late Pennsylvanian intramontane basin in the Pyrenees: systematic affinities and palaeoecological implications

Papers in Palaeontology, Volume 9, Issue 5, September/October 2023., 2023
Abstract The first anatomically preserved wood specimens of an upland Carboniferous flora from the Iberian Peninsula are reported from the Erillcastell Basin (Eastern Pyrenees, Catalonia, Spain). Two taxa are described, a calamitacean Equisetales (Arthropitys sp.) and a Cordaitales (Dadoxylon sp.).

Spatial patterns and climatic drivers of phylogenetic structure for ferns along the longest elevational gradient in the world

Ecography, Volume 2023, Issue 1, January 2023., 2023
Many biodiversity hotspots are located in montane regions, thus, understanding the underlying mechanisms driving species assembly along elevational gradients is of major interest in ecology and biogeography. Here, we assess spatial patterns and climatic drivers, and the effects of clade age, on patterns of phylogenetic structure of ferns along the ...

First record of late Devonian-early Carboniferous palynoflora from the Lipak Formation, Spiti Basin, Tethyan Himalaya, India, and their biostratigraphic implications

Journal of the Palaeontological Society of India, 2023
The present work elucidates palynofloral records from the Lipak Formation (late Devonian– early Carboniferous) of the Spiti Basin. The study has been carried out from three different sections of Spiti and Pin valleys to look for the signatures of ...

Plant genomes: Markers of evolutionary history and drivers of evolutionary change

PLANTS, PEOPLE, PLANET, Volume 3, Issue 1, Page 74-82, January 2021., 2021
Plant genomes hold the key to understanding the evolutionary history of plants, a lineage that goes back nearly a billion years and contains nearly half a million living species. This history—or phylogeny—is both a record of life now past and a powerful predictive tool for both basic and applied plant science.
