Endogenous NO Is Involved in Dissimilar Responses to Rehydration and Pb(NO3)2 in Ramalina farinacea Thalli and Its Isolated Phycobionts

Microbial Ecology, 2019
Lichens undergo desiccation/rehydration cycles and are permeable to heavy metals, which induce free radicals. Nitrogen monoxide (NO) regulates important cellular functions, but the research on lichen NO is still very scarce. In Ramalina farinacea thalli, NO seems to be involved in the peroxidative damage caused by air pollution, antioxidant defence and

Secondary Chemistry of Lichen-forming Fungi: Chemosyndromic Variation and DNA-analyses of Cultures and Chemotypes in the Ramalina farinacea Complex

, 2015
The Ramalina farinacea (L.) Ach. complex has a world-wide distribution. The thalli are highly variable both morphologically and chemically, with various β-orcinol depsidones being produced as secondary medullary compounds.

Spatial and Temporal Effects of Train-sourced Air Pollution on Lichen (Ramalina farinacea) Near Bellinngham, WA

, 2015
This project examines effects of train-specific air contaminants on Ramalina farinacea along the BNSF rail corridor near Bellingham. There is minimal research on train-specific effects on lichens.
