Wang Y., Zhang Y., Li R., Qian B., Du X., Qiu X., Chen M., Shi G., Wei J., Wei X.-L. & Wu Q. (2024): Exploration on cold adaptation of Antarctic lichen via detection of positive selection genes - IMA Fungus, 15: 29 [12 p.]

Lichen as mutualistic symbiosis is the dominant organism in various extreme terrestrial environment on Earth, however, the mechanisms of their adaptation to extreme habitats have not been fully elucidated. In this study, we chose the Antarctic dominant lichen species Usnea aurantiacoatra to generate a high-quality genome, carried out phylogenetic analysis using maximum likelihood and identify genes under positive selection. We performed functional enrichment analysis on the positively selected genes … Read more...

Grube M., Muggia L., Baloch E., Hametner C. & Stocker-Wörgötter E. (2017): Symbioses of lichen-forming fungi with trentepohlialean algae - In: Grube M., Seckbach J. & Muggia L. (eds), Algal and Cyanobacteria Symbioses, p. 85–110, World Scientific Europe

chapter in book; Trentepohliaceae are a distinct lineage of green algae frequently found in association with lichen-forming fungi. We review the current knowledge about the phenotypic diversity of this group of algae, which is complemented by currently available molecular data. These data do not confirm the traditional classification of the genera based on morphological inferences. We also present more specific data on the association patterns of epiphyllous representatives in tropical rain forests. … Read more...

chapter in book; The algal genus Trebouxia comprises non-motile coccoid green algae with characteristic pyrenoids and a lobate chloroplasts. Strains of Trebouxia are present in approximately one half of all lichens. Therefore, it has become one of the best studied phycobionts with respect to its diversity in lichen symbioses. Studies have focused on phylogenetic relationships of the lichenized strains and on the specificity of occurrence with mycobiont (= lichen) species, and on its ecological responses. … Read more...

Rikkinen J. (2017): Symbiotic cyanobacteria in lichens - In: Grube M., Seckbach J. & Muggia L. (eds), Algal and Cyanobacteria Symbioses, p. 147–167, World Scientific Europe

chapter in book; Cyanolichens are obligate symbioses between fungi and cyanobacteria. They occur in many types of environments ranging from Arctic tundra and semi-deserts to tropical rainforests. Possibly even a majority of their global species diversity has not yet been described. Symbiotic cyanobacteria provide both photosynthate and fixed nitrogen to the fungal host and the relative importance of these functions differs in different cyanolichens. The cyanobiont can either be the sole photosynthetic … Read more...

Sadowsky A. & Meeßen J. (2017): The resistance of lichen photobionts to extreme abiotic stressors on earth, in space and in simulations - In: Grube M., Seckbach J. & Muggia L. (eds), Algal and Cyanobacteria Symbioses, p. 575–609, World Scientific Europe

chapter in book; Lichen symbioses show outstanding resistance to extreme environmental conditions and are, therefore, used as model systems in astrobiological research. Lichens from harsh environments such as the Antarctic continent are of special interest. Although the symbiotic state provides a variety of adaptations to the extremes of radiation, temperature, and water supply, some aposymbiotically cultured lichen photobionts show considerable autonomous stress tolerance. Although lichens are valuable … Read more...

Hrouzek P. (2017): Secondary metabolites produced by cyanobacteria in symbiotic associations - In: Grube M., Seckbach J. & Muggia L. (eds), Algal and Cyanobacteria Symbioses, p. 611–626, World Scientific Europe

chapter in book; Cyanobacteria enter into various symbiotic interactions with a wide spectrum of organisms distantly related to the tree of life. The level of proximity varies immensely in these interactions. As many other prokaryotes, the majority of cyanobacterial strains possess synthetic machineries of employing non-ribozomal peptide synthetases, and polyketide synthetases, which can be combined to produce a large diversity of chemical structures from low-molecular alkaloids up to large peptides. … Read more...

Raven J.A. (2017): Symbiosis involving photosynthetic organisms - In: Grube M., Seckbach J. & Muggia L. (eds), Algal and Cyanobacteria Symbioses, p. 3–41, World Scientific Europe

Chapter in book; Symbioses with one photosynthetically competent partner can have “added value” in terms of the metabolic capacity of the symbiosis relative to that of the individual partners, though there may also be other reciprocal rewards. All photosynthetic eukaryotes depend on symbiosis. Symbioses, in the past, gained chloroplasts by genetic integration of inhabitant cyanobacteria in primary endosymbiosis. Some subsequent lineages genetically integrated eukaryotic photosynthetic inhabitants … Read more...

(2024): Atmospheric pollution by potentially toxic elements: measurement and risk assessment using lichen transplants - International Journal of Environmental Health Research, 34(3): 1270–1283

The lichen Usnea articulata collected from an unpolluted area was exposed for 6 months at 26 sites for the sample chosenusing a stratified random design, and the content of potentially toxic elements (PTEs) including As, Cd, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sn, V, and Zn, was assessed using ICP-MS. The health risk for both adults and children was then calculated using the PTEs concentrations. The results showed that despite the hostile urban conditions, transplanted lichens depicted clear deposition … Read more...

Lawal O. & Ochei L.C. (2024): Lichen - air quality association rule mining for urban environments in the tropics - International Journal of Environmental Health Research, 34(3): 1713–1724

There are significant gaps in air quality monitoring across many low- and middle-income countries, which can be filled by bioindicators like lichen. This study examined the links between lichen and air quality across urban environments in Nigeria. Lichen surveys and air quality monitoring were carried out across four major cities focusing on NO2, SO2, PM2.5, and PM10. Association rule mining was used to identify robust rules defining the association between lichen and air quality categories. For … Read more...
