light-dependent reaction. Isoform PORB and PORC are interchangeable and functionally redundant in developed plants. PORB as well as PORA, functions in assembly of prolamellar bodies and in photoactive protochlorophylluide formation in etiolated seedlings. At the onset of greening, prolamellar bodies are important for efficient capture of light energy for photoconversion under various light conditions, and PORC, which is induced by light irradiation, contributes to photoprotection during greening of the etiolated seedlings
