Spartial distribution of cyanobacterial phylotypes in Antarctic Dry Valley soil biotopes
MetadataShow full item record
Recent advances in moleculr methods have enabled the analysis of cyanobacterial diversity using PCR- based approaches. Snap-shot techniques such as 16S rDNA library construction and DGGE have allowed for increased access and better understanding of cyanobacterial diversity from diverse biotopes. In this investigation, 16s rDNA analysis and DGGE profiling were used to study the diversity of cyanobacteria along a transect of increasing altitude in the Miers Valley, Eastern Antarctica..."
