Genes and groups of genes commonly shared between species, studies show
...colleagues reported that the biofilms harbor novel archaeal
organisms that appear to be extremely small compared to other life forms. "Analysis of how microorganisms respond to their environments and the role of exchange of genetic material in adaptation and evolution is important if we are to understand im...
From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea
...just now beginning to focus on the large number of archaeal

cell membranes. This finding indicates that an archaean community may have inhabited the region more...
Ammonia-loving archaea win landslide majority
...chleper. The tally suggested that copies of the archaeal
gene in the soil samples were up to 3,000 times more abundant than copies of the bacterial gene. High amounts of lipids specific to crenarchaeota confirmed the organism's presence. At Penn State, Schuster used a novel technique to directly sequenc...
DOE JGI releases IMG 1.5 with curated archaeal genomes
...ources. Towards this goal, IMG 1.5 now contains 22 archaeal
genomes with curated gene models and detailed documentation of the methodology and standards employed for achieving this goal. A separate IMG Curated Archaeal Genomes data mart ( http://img.jgi.doe.gov/archaeal_qa/ ) contains these genomes with thei...

Prediction of a prokaryotic RNA-silencing system
...rative genomic analysis of CRISPR and cas genes in archaeal
and bacterial genome sequences retrieved from National Center for Biotechnology Information (NCBI) databases. Makarova et al. identified a number of cas genes that are always located close to CRISPR clusters and encode proteins potentially involved...
