a
Because spermidine rather than spermine is one of the major polyamines in cyanobacteria, the spermine/spermidine synthase gene is tentatively abbreviated as SPDS (spermidine synthase).
b
Prochlorococcus marinus includes all 12 strains listed in the Cyanobase (http://genome.microbedb.jp/cyanobase/).
