Chloroplasts call for help

Chloroplasts are the powerplants of the plant cell and produce energy from light and air. These organelles are extremely sensitive to the environment: abiotic factors such as light and salinity have strong impact on the development and function of the chloroplasts.

Luckily, stressed chloroplasts can call for help from the nucleus via so-called retrograde signals. These signals adjust nuclear gene expression to help restore the chloroplast, but also to adjust whole plant development.

 

We aim to investigate how chloroplasts contribute to the perception of and the adaptation to changing environments, and how this helps plants to tolerate abiotic stresses.
