a

GenBank accession numbers for the ITS sequences reported or used here are also shown. Strain information is organized by genetically defined clades described in this work. Chl b/a2 ratios are listed for Prochlorococcus cells grown at 17 to 27 μmol of Q m−2 s−1. Values in bold are from this work. Other values are taken from references 28, 29, and 31. —, environmental sequence, no pigment data available. ND, not determined.

b

MIT, Massachusetts Institute of Technology.

c

MED4Ax is an axenic derivative of the clonal strain MED4 (45).

d

Clonal derivative of LG.
