Small bacterial genomes are believed to be evolutionarily derived from larger genomes through massive loss of genes and are usually associated with symbiotic or pathogenic lifestyles. It is therefore ...
Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea
Elemental composition marine Prochlorococcus Synechococcus ecological stoichiometry
2014/5/21
The elemental composition of marine cyanobacteria is an important determinant of the ecological stoichiometry in low-latitude marine biomes. We analyzed the cellular carbon (C), nitrogen (N), and phos...
