Accelerated evolution associated with genome reduction in a free-living prokaryote (2005)

Dufresne, Alexis, Garczarek, Laurence, Partensky, Frédéric

Abstract Background Three complete genomes of Prochlorococcus species, the smallest and most abundant photosynthetic organism in the ocean, have recently been published. Comparative genome analyses...

Genome sequence of the cyanobacterium Prochlorococcus marinus SS120, a nearly minimal oxyphototrophic genome

Dufresne, Alexis, Salanoubat, Marcel, Partensky, Frédéric, Artiguenave, François, Axmann, Ilka M., Barbe, Valérie, ...

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...

Accelerated evolution associated with genome reduction in a free-living prokaryote

Dufresne, Alexis, Garczarek, Laurence, Partensky, Frédéric

Prochlorococcus sp. are marine bacteria with very small genomes. The mechanisms by which these reduced genomes have evolved appears, however, to be distinct from those that have led to small genome...

The cyanobacterial genome core and the origin of photosynthesis

Mulkidjanian, Armen Y., Koonin, Eugene V., Makarova, Kira S., Mekhedov, Sergey L., Sorokin, Alexander, Wolf, Yuri I., ...

Comparative analysis of 15 complete cyanobacterial genome sequences, including “near minimal” genomes of five strains of Prochlorococcus spp., revealed 1,054 protein families [core cyanobacterial...

Diversity and evolution of phycobilisomes in marine Synechococcus spp.: a comparative genomics study

Six, Christophe, Thomas, Jean-Claude, Garczarek, Laurence, Ostrowski, Martin, Dufresne, Alexis, Blot, Nicolas, ...

By comparing Synechococcus genomes, candidate genes required for the production of phycobiliproteins, which are part of the light-harvesting antenna complexes called phycobilisomes, were identified....

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.
