Insights into U‐to‐C RNA editing from the lycophyte Phylloglossum drummondii

open access: yesThe Plant Journal, Volume 119, Issue 1, Page 445-459, July 2024.
Significance Statement U‐to‐C RNA editing is only found in plants, and within plants, only in some hornworts, lycophytes and ferns. The unusual lycophyte Phylloglossum drummondii contains four U‐to‐C editing sites that can be matched with four putative U‐to‐C editing enzymes, making it a useful model for the study of this uncommon process.

The Biomimetic Synthesis of Polyarylated Fluorenes, Relevant to Selaginellaceae Polyphenols, Leading to the Spontaneous Formation of Stable Radicals

open access: yesChemPlusChem, Volume 89, Issue 4, April 2024.
A biomimetic synthesis of polyarylated fluorenes similar to naturally occurring selaginpulvilines is reported in this work. Some of the synthesized fluorens spontaneously decompose to solid‐state stable radical. Various techniques were employed, including cyclic voltammetry, EPR spectroscopy, and DFT calculation to shine a light on the origin and ...
