Abstract Lichens are the archetypal symbiosis and one for which term was coined. Although application of shotgun sequencing techniques has shown that many lichen symbioses can harbour more symbionts than canonically recognized fungus photobiont, no global census organismal composition been undertaken. Here, we analyze genome content 437 metagenomes from six continents, show four bacterial lineages occur in majority symbioses, at a frequency on par with algal photobionts. A single genus,...
In lichen research, metagenomes are increasingly being used for evaluating symbiont composition and metabolic potential, but the overall content limitations of these have not been assessed. We reassembled over 400 publicly available metagenomes, generated metagenome-assembled genomes (MAGs), constructed phylogenomic trees, mapped MAG occurrence frequency across data set. Ninety-seven percent 1,000 recovered MAGs were bacterial or fungal that provides most cellular mass. Our mapping detailed...
Usnic acid, a secondary metabolite of many lichen species, is utilized as natural source polymer network synthesis.
Bryoria (Parmeliaceae, Ascomycota) is one of the dominant genera hair lichens in western North America and characteristic high-elevation conifer forest ecosystems. In areas where abundant, it common to find thalli which thalline filaments become conglutinated, forming brittle dead zones. After sampling across Canada northwestern United States at different times year, we found that this dieback phenomenon associated with winter growth a mold-forming basidiomycete. We report fungus belongs...
Seventy-four lichen species, identified from both modern and historical vouchers, are reported for Lizard Lick, Wake County, North Carolina. Like many granite flat rock areas in the southeastern United States, Lick flora is a unique combination of Piedmont Coastal Plain species. The shares 24 species common with two similar, nearby sites, Temple Flat Rock Preserve Turnipseed Nature Preserve. Species characteristic habitats were found, including Peltula cylindrica Pyrenopsis portoricensis;...
Abstract Calicium poculatum and Ramboldia canadensis are described as new species occurring on Larix laricina . , currently known from four Canadian provinces the US state of Minnesota, is characterized by its short-stalked black ascomata, short ascospores occurrence a parasite Lecanora caesiorubella subsp. saximontana Based DNA sequence data, nearest relative likewise parasitic episcalaris only dead wood snags in Canada, engages fully developed lichen symbiosis with Trebouxia simplex statu...
