Algal switching among lichen symbioses.
- M. Piercey-Normore, P. Depriest
- Biology, Medicine
- American journal of botany
- 1 August 2001
Lichens are intimate and long-term symbioses of algae and fungi. Such intimate associations are often hypothesized to have undergone long periods of symbiotic interdependence and coevolution.… Expand
The lichen-forming ascomycete Evernia mesomorpha associates with multiple genotypes of Trebouxia jamesii.
- M. Piercey-Normore
- Biology, Medicine
- The New phytologist
- 2006
The epiphyte Evernia mesomorpha forms a lichen association with green algae in the genus Trebouxia. Little is known about the population structure of E. mesomorpha. Here, population structure of the… Expand
Molecular Phylogenetic Analysis, Trichothecene Chemotype Patterns, and Variation in Aggressiveness of Fusarium Isolates Causing Head Blight in Wheat.
- A. Malihipour, J. Gilbert, M. Piercey-Normore, S. Cloutier

- 5 June 2012
Certain Fusarium species cause Fusarium head blight (FHB) in wheat and other small grains. Differences in characteristics of the pathogen species/isolates used in breeding programs may affect… Expand
Selection of algal genotypes by three species of lichen fungi in the genus Cladonia
- M. Piercey-Normore
- Biology
- 1 July 2004
The lichen-forming fungal genus Cladonia P. Browne associates with green algae in the genus Trebouxia de Puymaly. Genetic structure of the algal symbionts in Cladonia gracilis (L.) Willd., Cladonia… Expand
Phylogenetic generic classification of parmelioid lichens (Parmeliaceae,Ascomycota) based on molecular, morphological and chemical evidence.
- A. Crespo, F. Kauff, +39 authors H. T. Lumbsch
- Biology
- 1 December 2010
Parmelioid lichens are a diverse and ubiquitous group of foliose lichens. Generic delimitation in parmelioid lichens has been in a state of flux since the late 1960s with the segregation of the… Expand
Role of pH on antioxidants production by Spirulina (Arthrospira) platensis

- Chemistry, Medicine
- Brazilian journal of microbiology : [publication…
- 2 March 2016
Algae can tolerate a broad range of growing conditions but extreme conditions may lead to the generation of highly dangerous reactive oxygen species (ROS), which may cause the deterioration of cell… Expand
Putative identification of the usnic acid biosynthetic gene cluster by de novo whole-genome sequencing of a lichen-forming fungus.
- Mona Abdel-Hameed, R. Bertrand, M. Piercey-Normore, J. Sorensen
- Biology, Medicine
- Fungal biology
- 1 March 2016
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 fungal partner of Cladonia uncialis. This… Expand
Vegetatively reproducing fungi in three genera of the Parmeliaceae share divergent algal partners
- M. Piercey-Normore
- Biology
- 9 December 2009
Abstract The taxonomic pattern of algal association with lichen fungi may be explained by the fungal selection of algae that are available in the habitat, genetic compatibility between symbionts or… Expand
Convergent evolution in Cladonia gracilis and allies
- Kyle M. Fontaine, T. Ahti, M. Piercey-Normore
- Biology
- 1 May 2010
Members of the Cladonia gracilis group of lichen fungi are common terrestrial lichens where morphological features are more similar between members of the C. gracilis species complex and allied… Expand
Genetically divergent algae shape an epiphytic lichen community on Jack Pine in Manitoba
- Matthew Doering, M. Piercey-Normore
- Biology
- 2009
Algal genotypes should freely associate with different lichen fungi that grow in the same confined habitat giving the appearance of low levels of selectivity and specificity. If genetic compat-… Expand
