Prochlorococcus marinus, the dominant photosynthetic organism in the ocean, is found in two main ecological forms: high-light-adapted genotypes in the upper part of the water column and...
High-frequency mutations in a plasmid-encoded gas vesicle gene in Halobacterium halobium
DasSarma, Shiladitya, Halladay, John T., Jones, Jeffrey G., Donovan, John W., Giannasca, Paul J., De Marsac, Nicole Tandeau
Gas vesicle-deficient mutants of Halobacterium halobium arise spontaneously at high frequency (about 1%). The mutants are readily detected, forming translucent colonies on agar plates in contrast to...

Comparative analysis of related biosynthetic gene clusters can provide new insights into the versatility of these pathways and allow the discovery of new natural products. The freshwater...
Unraveling the genomic mosaic of a ubiquitous genus of marine cyanobacteria
Dufresne, Alexis, Ostrowski, Martin, Scanlan, David J, Garczarek, Laurence, Mazard, Sophie, Palenik, Brian P, ...
Local niche occupancy of marine Synechococcus lineages is facilitated by lateral gene transfers. Genomic islands act as repositories for these transferred genes.
