Low-light-adapted Prochlorococcus species possess specific antennae for each photosystem

Article Abstract:

Prochlorococcus have a large depth distribution in the occurrence of distinct genotypes adapted to either low or high-light-niches. The moderate low-light-adapted strain Prochlorococcus is described to have one iron-stress-induced gene encoding an antenna protein serving photosystem.

Antenna ring around photosystem I

Article Abstract:

Issues concerning ways in which oxyphotobacteria enhance the scarcely available light in deep oceanic locations are discussed. Particular attention is given to techniques of collecting light by using the antenna rings.

The genome of a motile marine synechococcus

Article Abstract:

The megabase genome of synechococcus strain WH8102 is described to be influenced by horizontal gene transfer. WH8102 have adopted strategies for conserving limited iron sores by using nickel and cobalt in some enzymes.
