Table II. Complete list of genes showing significant transcriptional changes in cells of the Synechocystis 6803 mutant Δsml0013::Km relative to the wild type.

The relative expression (fold change) of these genes is given for HC-grown cells (Δsml0013 HC/wild-type HC) and cells shifted from HC into LC (Δsml0013 LC/wild-type LC) for 24 h. Changes of 1.87-fold or greater and 0.53-fold or less indicate significantly increased or decreased transcript levels.
