Charlotte Gommers

Assistant Professor


Member of the retrograde signalling team since: February 2019

Worked before at: Utrecht University (PhD), Center for Research in Agricultural Genomics (Barcelona, Postdoc)

Research interests: I am fascinated about the way plants are capable of integrating various signals from their environment to optimise growth and survival. During my post-doc I discovered how chloroplast-derived retrograde signals can alter nuclear gene expression to interfere with other pathways, such as the light signalling pathway that is activated by photoreceptors. I would like to find out now, how (stressful) environmental changes affect chloroplasts and the release of retrograde signals, and how these signals integrate in the nucleus to promote optimal survival.

Konstantinos Ntoumos

PhD student


Member of the retrograde signalling team since: September 2019

Studied at: Agricultural University of Athens (Greece)


Research interests: I am very much interested in the physiological responses of model plants and cultivated plants to various abiotic stress factors, on plant defense mechanisms and adaptation strategies to salt stress on both physiological and molecular level and on weed management. Now, I study the effect of salt stress on the chloroplast and how chloroplast retrograde signals affect nuclear gene expression and whole plant development.

MSc student - Erasmus exchange 


Member of the retrograde signalling team since: February 2020

Studies at: Darmstadt University


Research interests: Have you ever thought about the plant's reaction on green light? No? Well I do think about it.
My combined fascination for molecular biology and plants motivate me, to understand why plants show shade avoidance-like phenotypes under green light. Therefore I will investigate, which photoreceptor initally senses the green light and triggers downstream pathways.
