HPLC elution profiles for pigments for two cyanobacteria. (A) HPLC elution profile for pigments extracted from the wild-type (solid line) and cruE (dotted line) mutant strains of Synechococcus sp. strain PCC 7002. (B) HPLC elution profile for pigments extracted from wild-type (solid line) and sll0254/cruE (dotted line) mutant strains of Synechocystis sp. strain PCC 6803. s, synechoxanthin; m1, myxol-2′-fucoside; m2, myxol-2′-dimethylfucoside; z, zeaxanthin; he, 3′-hydroxy-echinenone; z-cis, cis-zeaxanthin; c, cryptoxanthin; e, echinenone; b, β-carotene.
