Regulation of chloroplast biogenesis in barley


, : Regulation of chloroplast biogenesis in barley. Plant molecular biology 2 Proceedings of a NATO Advanced Study Institute, 14-23 May 1990, Elmau, Germany: 439-447

Using Hordeum vulgare Morex, the accumulation of chlorophyll and carotenoids during chloroplast biogenesis was quantified. Results revealed that activation of tetrapyrrole and terpenoid biosynthetic pathways parallels the activation of plastid gene expression, indicating that the nuclear genes encoding enzymes in these pathways are modulated by a factor produced in transcriptionally active plastids. A procedure was developed for the isolation of plastid RNA polymerase using pea chloroplasts.
