Organelles and early development

Team OGE / Etienne Delannoy

Function of organellar genome expression factors

During the early phases of development, there is a close interplay and coordination between the setting-up of functional organelles and plant development. To illustrate this relationship we are studying 2 different systems:

• Skoto-morphogenesis which is altered in some mutants defective for organelle gene expression.

• C4 differentiation between bundle sheath and mesophyll cells. We are characterizing the proteome and transcriptome of the plastid nucleoid in this dynamic context.
