Stability of nucleic acids in immobilized and desiccated Nostoc commune UTEX584 (Cyanobacteria) [PDF]
FEMS Microbiology Letters, 1987 Two microscale methods were developed to isolate and analyze the [2-14C]uracil-labeled nucleic acids of immobilized, dried cells of the desiccation-tolerant cyanobacterium Nostoc commune UTEX584. The incidence of single-strand breaks (‘nicks’) in DNA of light-desiccated, but not dark-desiccated cells, was demonstrated by the use of DNA modification ...

Research Bias in Long‐Term Monitoring of Antarctic Nearshore Marine and Terrestrial Biota
Global Change Biology, Volume 31, Issue 8, August 2025.Antarctic wildlife is under pressure from environmental changes and human activity, but how well is Antarctica's coastal biota being monitored? While over half of the long‐term monitoring studies spanned more than 10 years and/or included environmental data, they were limited in number, mostly focused on penguins and marine mammals, were unevenly ...

A Native Cyanobacteria, Nostoc, as a Biofertilizer [PDF]
, 2014 The native cyanobacteria, Nostoc, is found throughout much of the US and has a cosmopolitan distribution. It is a found in free-living colonies on the surface of the ground, growing symbiotically with fungi to form lichen species, and grows symbiotically

A comparative genomics approach to understanding the biosynthesis of the sunscreen scytonemin in cyanobacteria [PDF]
, 2009 BACKGROUND: The extracellular sunscreen scytonemin is the most common and widespread indole-alkaloid among cyanobacteria. Previous research using the cyanobacterium Nostoc punctiforme ATCC 29133 revealed a unique 18-gene cluster (NpR1276 to NpR1259 in ...

Unusual Water Flux in the Extracellular Polysaccharide of the Cyanobacterium Nostoc commune [PDF]
Applied and Environmental Microbiology, 2003 ABSTRACT The speed of water uptake by desiccated Nostoc commune was found to depend upon the duration of desiccation. The rehydration of desiccated colonies led to marked, time-dependent changes in structure and ultrastructure and fluctuations in the composition of the transcriptome.
