Fungus-specific SSR markers in the Antarctic lichens Usnea antarctica and U. aurantiacoatra (Parmeliaceae, Ascomycota)1
PREMISE OF THE STUDY Usnea antarctica and U. aurantiacoatra (Parmeliaceae) are common lichens in the maritime Antarctic. These species share the same habitats on King George Island (South Shetland Islands, Antarctica) and are distinguishable based on reproductive strategies. METHODS AND RESULTS We developed 23 fungus-specific simple sequence repeat (SSR) markers that cross-amplify between the...
متن کاملGrowth Rate of Usnea aurantiacoatra (Jacq.) Bory on Fildes Peninsula, Antarctica and Its Climatic Background
The ages of a fruticose lichen of Usnea aurantiacoatra (Jacq.) Bory, from Fildes Peninsula, King George Island, Southwest Antarctic, were determined by radiocarbon (14C), and it is 1993-1996 at bottom and 2006-2007 at top of the lichen branch. The growth rates of U. aurantiacoatra calculated are 4.3 to 5.5 mm year(-1) based on its length and ages. The comparisons show that the growth rates of U...
متن کاملPricia antarctica gen. nov., sp. nov., a member of the family Flavobacteriaceae, isolated from Antarctic intertidal sediment.
A yellow-coloured, rod-shaped, Gram-reaction- and Gram-staining-negative, non-motile and aerobic bacterium, designated strain ZS1-8(T), was isolated from a sample of sandy intertidal sediment collected from the Antarctic coast. Flexirubin-type pigments were absent. In phylogenetic analyses based on 16S rRNA gene sequences, strain ZS1-8(T) formed a distinct phyletic line and the results indicate...
متن کاملLewinella antarctica sp. nov., a marine bacterium isolated from Antarctic seawater.
A marine bacterium, designated IMCC3223T, was isolated from Antarctic coastal seawater and subjected to a polyphasic taxonomic investigation. Cells of the strain were Gram-negative, short to elongated rods that were orange-coloured but negative for flexirubin-type pigments, obligately aerobic, chemoheterotrophic and devoid of gliding or flagellar motility. On the basis of 16S rRNA gene sequence...
متن کاملDiversity of the lichenized fungi in King George Island, Antarctica, revealed by phylogenetic analysis of partial large subunit rDNA sequences.
Lichens are predominant and important components of flora in the terrestrial ecosystem of Antarctica. However, relatively few researches on the phylogenetic position of Antarctic lichen-forming fungi have been accomplished. In this study, partial sequences of nuclear large subunit rDNAs from 50 Antarctic specimens were obtained and the phylogeny was reconstructed. Antarctic lichen species were ...
