Polygalacturonase Isozymes in the Cyanolichen Peltigera canina
Journal of Plant Physiology, 1996Summary Polygalacturonase is produced by the cyanolichen Peltigera canina . In cell free extracts of thalli, enzyme activity was detected in the soluble fraction and in the cell wall. Polygalacturonase was also secreted to the incubation medium. Three forms of the enzyme differing in isoelectric point were detected.

Dry-hot stress significantly reduced the nitrogenase activity of epiphytic cyanolichen
Science of the Total Environment, 2018Nitrogen (N) fixed by epiphytic cyanolichens (i.e. lichens that contain cyanobacterial symbionts) is thought to be the most important resource of this nutrient in some natural forest ecosystems. Although a great deal of work has been carried out to evaluate the biomass of this group as well as its contribution to ecosystem N budgets, empirical studies ...

Structural characterization of a galactomannan from the cyanolichen Leptogium azureum
Carbohydrate Polymers, 2003Abstract A galactomannan was isolated from the cyanolichen Leptogium azureum via successive alkaline extraction and precipitation with Fehling solution. The structure of the polysaccharide was investigated using NMR spectroscopy, methylation analysis, Smith degradation, and HPSEC-MALLS.

Survival and Growth of Cyanolichen Transplants in Douglas-Fir Forest Canopies
Bryologist, 1998In the Oregon Cascades, epiphytic cyanolichens are abundant in old-growth forest canopies, but they accumulate very slowly in young forests. We evaluated whether epiphytic cyanolichens require old growth and/or thick, underlying moss mats to achieve normal rates of growth and mortality.

Sulfur is in the Air: Cyanolichen Marriages and Pollution
Acta Biotheoretica, 2023Cyanolichens are symbiotic organisms involving cyanobacteria and fungi (bipartite) or with the addition of an algal partner (tripartite). Cyanolichens are known for their heightened susceptibility to environmental pollution. We focus here on the impacts on cyanolichens due to rising air pollution; we are especially interested in the role of sulfur ...

Additions to the Cyanolichens of the Andes
Herzogia, 2015Abstract: Jorgensen, P. M. & Palice, Z. 2015. Additions to the cyanolichens of the Andes. — Herzogia 28: 285–287. Heppia adglutinata and Lempholemma intricatum are recorded as new to South America from the Andes in Ecuador. A further specimen of “Collema” paramense is recorded from paramos at above 4000 m.

Extensive photobiont sharing in a rapidly radiating cyanolichen clade
Molecular Ecology, 2020AbstractRecent studies have uncovered remarkable diversity in Dictyonema s.lat. basidiolichens, here recognized as subtribe Dictyonemateae. This group includes five genera and 148 species, but hundreds more await description. The photobionts of these lichens belong to Rhizonema, a recently resurrected cyanobacterial genus known by a single species.
