The Nile red stained PHB granules (A), relative transcript levels (B), and their band intensity ratios of gene/16s (C) of genes involved in PHB synthesis, glycogen degradation, proline-glutamate conversion, and neighboring pathways in Synechocystis WTc, Δadc1c, OXP, and OXP/Δadc1 strains under BG11-N-P + A condition at day 7 of treatment. The 16s rRNA was used as reference control
