Hormonal Crosstalk in Plant Development - Helene Robert Boisivon

PhD Topics

1. Developmental response induced by abiotic stress during seed development in Brassica sp.

Supervisor: Helene Robert Boisivon, Ph.D.

Annotation: Food production mostly relies on a proper sexual plant reproduction. Therefore research in fundamental aspects of seed development is crucial to the understanding of processes involved in seed viability. Embryo development follows a strict pattern of cell divisions and differentiations, which, if whenever affected, perturbs embryo shape and viability. The plant hormone auxin and cytokinin are mediators of these developmental events. Dynamic changes in auxin distribution during embryo development are crucial for establishment of embryonic root and shoot. We showed that a local production of auxin regulates this embryonic auxin distribution. Our research projects focus on how environmental and endogenous signals are integrated at the cellular level into the regulation of this auxin transport both in embryonic and post-embryonic tissues.

Project description: Our next challenge is to identify the molecular components that regulate the observed developmental changes in inflorescence and seed production induced by abiotic stresses.

Techniques involved: In vitro tissue culture, Genetics, Microscopy, Molecular Biology, Cellular Biology in context of Plant reproduction.

We are seeking: An enthusiastic and motivated student who would be interested to carry out his/her PhD research project in our team. The candidate should have MSc degree in the area of Life sciences. Experience in molecular biology/cell biology/plant culture/microscopy is a plus. English will be our communication language.

We offer: Ambitious laboratory facilities, young, international and dynamic work environment. Experience acquisition in a wide range of biological techniques and methods.
