Multiplication of antenna genes as a major adaptation to low light in a marine prokaryote

Garczarek, Laurence, Hess, Wolfgang R., Holtzendorff, Julia, Partensky, Frédéric

Two ecotypes of the prokaryote Prochlorococcus adapted to distinct light niches in the ocean have been described recently. These ecotypes are characterized by their different (divinyl-) chlorophyll...

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...
