The putative role of fumarprotocetraric acid in the manganese tolerance of the lichen Lecanora conizaeoides

The Lichenologist, 2007
Hauck & Huneck (2007) and Hauck et al. (2007) established that lichen secondary chemistry is related to metal absorption in the apoplast of lichens. Depsidones occurring in the medulla of the Mn2+ and Cu2+-sensitive epiphytic lichen Hypogymnia physodes were found to reduce the absorption of Mn2+ and Cu2+ at cation exchange sites (Hauck & Huneck

<p><strong>Allelopathic effect of the <em>Cladonia verticillaris </em>lichen extracts and fumarprotocetraric acid on the early growth of germinated seedlings in <em>Allium cepa </em>L.</strong></p> [PDF]

Bryophyte Diversity and Evolution, 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. It was observed that the length of the radicle was significantly stimulated by fumarprotocetraric acid at

Antimicrobial Activity of Cladonia verticillaris Lichen Preparations on Bacteria and Fungi of Medical Importance

Chinese Journal of Biology, Volume 2014, Issue 1, 2014., 2014
Cladonia verticillaris lichen lectin (ClaveLL) was purified using a previously established protocol and then evaluated for its potential antimicrobial activity. Initially, the autochthonous lichen was submitted to extraction with sodium phosphate buffer pH 7.0, followed by filtration and centrifugation to obtain crude extract.
