The lab investigates the positional information that tells cells where they are in plant embryos.
AboutAbout the lab
Uncovering the positional information at work in early plant embryos
The Biological Sciences Group (Plant Positional Information) conducts research with the goal of uncovering the positional information that operates in early plant embryos.
Organs of a seedling, such as the cotyledons and roots, are always formed in fixed arrangements. The lab investigates how cells recognize where they are and activate genes accordingly.
Using the model plant Arabidopsis thaliana, the lab carries out analyses with reverse genetics approaches that make use of genome information.
The lab welcomes undergraduate and graduate students who would like to work on research together.
Key terms
- Positional information
- Information that allows a cell to know its position within the body. Differences in the concentration of substances, for example, are used
- Arabidopsis thaliana
- A model plant whose entire genome sequence has been determined. It has a rich collection of mutant lines in which specific genes are disrupted
- Transcription factor
- A protein that binds to a specific DNA sequence near a gene and determines in which cells that gene is activated
ResearchResearch themes
In plant seedlings, organs such as the cotyledons and roots are always formed at fixed positions. The lab investigates, in early Arabidopsis embryos, the positional information that underlies this mechanism.
