SIG2 and SIG6-mediated plastid transcription is required for PhANG expression. (a) The average luciferase activity of 2-day-old etiolated (− light) and de-etiolated (+ light) seedlings that harbour the Luc gene under the control of a minimal LHCB1.2 promoter (6–3) and that have been germinated in the presence or absence of 50 μg ml−1 rifampicin is shown. Data shown are the mean ± standard error of the mean (SEM) of 16 individual seedlings. (b) Image of 3-day-old sigma mutant seedlings. Quantitative polymerase chain reaction (qPCR) analysis of steady-state (c) plastid and (d) PhANG mRNA transcript levels of 2-day-old seedlings. Data shown are the mean ± SEM of triplicate reactions of a representative experiment.
