Abdel-Hameed M., Bertrand R.L., Piercey-Normore P.D. & Sorensen J.L. (2016): Putative identification of the usnic acid biosynthetic gene cluster by de novo whole-genome sequencing of a lichen-forming fungus - Fungal Biology, 120(3): 306–316

Highlights: • The genome of the mycobiont of the lichen Cladonia uncialis has been sequenced. • There were 32 polyketide synthase genes annotated in the C. uncialis genome. • The usnic acid biosynthetic gene cluster has been putatively identified. • This is the first putative identification of an usnic acid gene cluster in lichen. To identify the biosynthetic gene cluster responsible for the biosynthesis of the polyketide usnic acid we carried out the de novo genome sequencing of the … EndNote Read more...

Abdel-Hameed M.E., Bertrand R.L., Donald L.J. & Sorensen J.L. (2018): Lichen ketosynthase domains are not responsible for inoperative polyketide synthases in Ascomycota hosts - Biochemical and Biophysical Research Communications, 503: 1228–1234

Efforts by lichenologists to characterize lichen polyketide synthases (PKS) through heterologous expression experiments have so far proved unfruitful. A determination of systematic causes of failure is therefore required. Three hypotheses involving the ketosynthase (KS) domain of lichen polyketide synthases (PKS) from Cladonia uncialis are tested: (1) Horizontal versus vertical gene transfer; (2) Typical versus atypical active site residues; (3) Typical versus atypical tertiary protein structure … EndNote Read more...

Abdullah S.M., Kolo K. & Sajadi S.M. (2020): Greener pathway toward the synthesis of lichen‐based ZnO@TiO2@SiO2 and Fe3O4@SiO2 nanocomposites and investigation of their biological activities - Food Science & Nutrition, 8(8): 4044–4054

A green way is introduced to biosynthesis of ZnO@TiO2@SiO2 and Fe3O4@SiO2 nanocomposites using the bioactive potential of Lecanora muralis (LM) lichen. UV‐Vis spectroscopy and GC–Mass analysis of the lichen show the presence of various bioactive constituents inside the lichen aqueous extract. The XRD, SEM, EDS, and elemental mapping techniques revealed the well fabrication of biosynthesized nanostructures. Also, investigation of antibacterial and antifungal activities of nanostructures demonstrated … URL EndNote Read more...

Abdulmanova S.U. & Ektova S.N. (2015): Variations in the growth rate of Cladonia lichens during long-term postfire successions in the North of West Siberia - Contemporary Problems of Ecology, 8(3): 326–336

This paper presents the results of studying the Cladonia lichen postfire growthrate dynamics in different zonal units of West Siberia. The relative growth rate of lichens in foresttundra and taiga zones was assessed with regard to the pyrogenic factor. The growth rate varied from 1.2 mm/year at the early stage of recovery succession to 11.9 mm/year at the stage of the closed lichen cover. The variations in lichen growth rates at different stages of recovery were reliable in southern and middle … EndNote Read more...

Abecasis L., Gamelas C.A., Justino A.R., Dionísio I., Canha N., Kertesz Z. & Almeida S.M. (2022): Spatial distribution of air pollution, hotspots and sources in an urban-industrial area in the Lisbon Metropolitan Area, Portugal—A biomonitoring approach - International Journal of Environmental Research and Public Health, 19: 1364 [20 p.]

This study aimed to understand the influence of industries (including steelworks, lime factories, and industry of metal waste management and treatment) on the air quality of the urbanindustrial area of Seixal (Portugal), where the local population has often expressed concerns regarding the air quality. The adopted strategy was based on biomonitoring of air pollution using transplanted lichens distributed over a grid to cover the study area. Moreover, the study was conducted during the first … URL EndNote Read more...

Abed R.M.M., Al-Sadi A.M., Al-Shehi M., Al-Hinai S. & Robinson M.D. (2013): Diversity of free-living and lichenized fungal communities in biological soil crusts of the Sultanate of Oman and their role in improving soil properties - Soil Biology and Biochemistry, 57: 695-705

Biological soil crusts of arid and semiarid regions are one of the least explored habitats with respect to the diversity of their fungal communities and the Arabian deserts, in particular, remains mycologically poorly investigated. Here, we investigate the diversity of free-living and lichen-forming fungal communities associated with crusts at two locations in Oman, using intensive cultivation and pyrosequencing, and their role in improving soil stability and hydrology. A total of 226 fungal … EndNote Read more...

Three aromatic constituents have been isolated from the lichen Roccella fuciformis: lepraric acid (1; R = H), the chromone (2), and ethyl orsellinate. Chemical and spectroscopic evidence is presented for the revised structure (1; R = H) of lepraric acid. EndNote Read more...
