Amplicon-Metagenomic Analysis of Fungi from Antarctic Terrestrial Habitats

open access: yesFrontiers in Microbiology, 2017
In cold environments such as polar regions, microorganisms play important ecological roles, and most of our knowledge about them comes from studies of cultivable microorganisms.

Success in the isolation and axenic culture of Anaptychia ciliaris (Physciaceae, Lecanoromycetes) mycobiont

open access: yesMycoscience, 2015
The aim of this study was to evaluate the optimum conditions for culturing Anaptychia ciliaris mycobionts in vitro and analyzing their ontogenetic development while in culture. After the testing of two germination and four development media, results of germination and growth were evaluated.

Cryptic species and species pairs in lichens: A discussion on the relationship between molecular phylogenies and morphological characters

open access: yesAnales del Jardín Botánico de Madrid, 2009
As with most disciplines in biology, molecular genetics has revolutionized our understanding of lichenized fungi. Nowhere has this been more true than in systematics, especially in the delimitation of species.

Phylogenetic studies of cyanobacterial lichens [PDF]

open access: yes, 2007
Phylogenetic studies of cyanobacterial lichens Lichens are symbiotic assemblages between fungi (mycobiont) and green algae (phycobiont) or/and cyanobacteria (cyanobiont). Fossil records show that lichen-like symbioses occurred already 600 million years

Sun exposure drives Antarctic cryptoendolithic community structure and composition [PDF]

open access: yes, 2019
The harsh environmental conditions of the ice-free regions of Continental Antarctica are considered one of the closest Martian analogues on Earth. There, rocks play a pivotal role as substratum for life and endolithism represents a primary habitat for ...

Population genetics of lichen-forming fungi - a review [PDF]

open access: yes, 2017
Population genetics investigates the distribution of genetic variation in natural populations and the genetic differentiation among populations. Lichen-forming fungi are exciting subjects for population genetic studies due to their obligate symbiosis ...
