The initial greening of the angiosperms involves a light activation of the photoreceptors that trigger photomorphogenesis, followed by the development of chloroplasts. In these organelles, the construction of the photosynthetic apparatus depends on the coordination of the expression of nuclear and plastid genes. Researchers at our laboratory are studying the expression of PAP8, an essential subunit of the RNA polymerase encoded by the plastid, localized and active in both the plastids and the nucleus.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
