Complete plastid genomes from Ophioglossum californicum, Psilotum nudum, and Equisetum hyemale reveal an ancestral land plant genome structure and resolve the position of Equisetales among monilophytes [PDF]

open access: yes, 2013
BACKGROUND: Plastid genome structure and content is remarkably conserved in land plants. This widespread conservation has facilitated taxon-rich phylogenetic analyses that have resolved organismal relationships among many land plant groups.

Vegetation and environmental dynamics in the central part of the Kola Peninsula during the past 13.3 ka as reflected by ancient plant DNA on sediments from Lake Imandra

open access: yesJournal of Quaternary Science, Volume 40, Issue 6, Page 1070-1096, August 2025.
ABSTRACT The first high‐resolution reconstruction of the vegetation and environmental changes during the last ca 13 300 cal a BP in the central part of the Kola Peninsula (NW Russia) was reconstructed based on sedimentary ancient DNA (sedaDNA) metabarcoding on sediment core Co1410 from Lake Imandra.

Greenhouse Gas Mitigation Potential of Temperate Fen Paludicultures

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
Peatlands lose their valuable carbon sink function under intensive land use and turn into greenhouse gas (GHG) emission hotspots. This study presents the first full GHG balance dataset for five potential fen paludicultures, measuring CO2, methane, and nitrous oxide emissions using manual and novel automated chambers across a water table gradient in ...

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

open access: yesChemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

The Role of Iron Chelation Therapy in Colorectal Cancer: A Systematic Review on Its Mechanisms and Therapeutic Potential

open access: yesCancer Medicine, Volume 14, Issue 13, July 2025.
Iron chelation is a promising yet underexplored strategy for colorectal cancer (CRC) treatment. Iron chelators have a dual role in inhibiting and potentially promoting cancer progression. Iron chelation affects key CRC pathways, including histone methylation, NDRG1 upregulation, Wnt/β‐catenin, and p53 modulation.
