Plants respond to changing light conditions by altering
the stoichiometry between components of the photosynthetic
electron transport chain of chloroplast thylakoids. We mea-
sured specific run-on transcription of the chloroplast genes
psaB, psbA and rbcL in pea (Pisum sativum L.) seedlings
grown under three different conditions of illumination: light
selective for photosystem I (PSI-light); light selective for pho-
tosystem II (PSII-light); and a combination of PSI- and PSII-
