Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.Host tree identity drives bark physico‐chemical filters (e.g., pH, metals) that shape epiphytic communities. We show that species‐specific functional traits, such as lichen substances and bryophyte growth forms, mediate these responses. Lichen metal homeostasis and bryophyte growth habit create distinct species thresholds and community change points ...

Oxidation reactions are required to produce atranorin from acetate by alginate-immobilized cells of Cladonia verticillaris. [PDF]
, 2000 Atranorin, a p-depside of the b-orcinol series, is produced by several Cladonia species. Immobilized cells of Cladonia verticillaris in calcium alginate are able to produce atranorin when they are supplied with 1.0 mM acetate as a precursor.

Lichen specific thallus mass and secondary compounds change across a retrogressive fire-driven chronosequence [PDF]
, 2012 In the long-term absence of major disturbances ecosystems enter a state of retrogression, which involves declining soil fertility and consequently a reduction in decomposition rates.

Mass Spectrometry Reviews, Volume 45, Issue 1, Page 120-146, January/February 2026.ABSTRACT Tannins are widespread specialized plant metabolites that contribute significantly to the polyphenol content of plant‐based diets. Their effects on human and animal health vary depending on their structure, with potential benefits including antioxidative, antimicrobial, anthelmintic, and anticarcinogenic properties.

Allelopathic effect of the Cladonia verticillaris lichen extracts and fumarprotocetraric acid on the early growth of germinated seedlings in Allium cepa L. [PDF]
, 1999 The allelopathic activity of the different type of Cladonia verticillaris lichen extracts and fumarprotocetraric acid on the early growth of A. cepa (IPA 6) germinated seedlings depends on their chemical composition and concentration, respectively.

American Journal of Botany, Volume 112, Issue 11, November 2025.Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

Mechanism Behind the Programmed Biosynthesis of Heterotrimeric Fungal Depside Thielavin A
Angewandte Chemie, Volume 136, Issue 20, May 13, 2024.The polyketide synthase ThiA that forms the heterotrimeric fungal depside thielavin A (1) has been identified and characterized. The thioesterase (TE) domain of ThiA was found to perform two consecutive esterification reactions as well as subsequent hydrolysis, and a plausible reaction mechanism for the TE‐catalyzed reactions has been proposed ...
