Transcription levels of phaP paralogs (a) and phbA, phbB, phbC, and phaZ paralogs (b) in USDA110 (WT, open bar) and ΔphaR (solid bar) grown in TY. Quantitative RT-PCR was performed as described in the main text to determine the transcription levels of the respective genes indicated along the horizontal axis, and data were normalized to the constitutive expression of sigA as the housekeeping sigma factor. Values are means ± standard deviation of three biologically independent experiments. ND: Not detected
