Seed dormancy is an ability of plants not to germinate even though the conditions are favourable. This allows seeds to ignore short episodes of favourable condition that would not last long enough to support whole plant life cycle.
Seed dormancy is therefore subject to strong selection and in Arabidopsis thaliana, Delay of Germination 1 (DOG1) gene has been selected by nature to align the dormancy strength with local conditions.
We study different aspects of DOG1 regulation including regulation by a non-protein coding transcript.


Seed dormancy is a crucial developmental transition in plants. The wrong decision to exit the dormancy and germinate can lead to immediate death or lower chances of reproduction. Therefore the key regulator of this process in nature Delay of Germination 1 (DOG1) is subject to extensive regulation.  In our lab we are studying different aspects of DOG1 regulation, that are briefly described below.
