Carotenoid and ROS contents, and transcript levels of genes for carotenogenesis and CBPs in Euhalothece Z-M001 during the early phase of salt deficiency. (A–D) Changes in carotenoid (β-Car and Zea) content (A), cellular ROS content (B), and expression levels of ocp, hcp and cdth (C), and zeaxanthin (crtR), and β-carotene (cruA) biosynthesis genes (D). Cells grown in 3% NaCl (+Na)-containing liquid S-medium were transferred to no-salt (0% NaCl, −Na) medium under growth light conditions for 1 h. Data represent mean ± S.E. (n = 3–4). §p < 0.01.
