Actors of organellar gene expression

Organellar gene expression relies on an extensive array of nucleus-encoded proteins that interact with RNA and DNA. The systematic characterization of these pivotal actors has long been the expertise of our team.

Our ongoing ANR project, JOAQUIN (2021-2024), led by B. Castandet, is dedicated to unraveling the function of plastid RNases in Arabidopsis, while concurrently investigating various PPR genes. To facilitate these investigations, we have harnessed the capabilities of the POPS transcriptome platform, enabling the development of dedicated molecular and bioinformatic pipelines for the comprehensive analysis of the organellar transcriptome, with a specific focus on post-transcriptional mechanisms.
