Research in my group focuses on identifying the molecular mechanisms that explain current plant biodiversity. The aim is twofold: (1) facilitating translation of knowledge in model plants to crops and (2) understanding how evolution works. Specifically, in a first line of research we characterize FLOWERING LOCUS C homologs in the model cereal Brachypodium to better understand temperature regulated flowering in cereals, which has applications towards plant breeding. This includes epigenetic, transcriptional and post-transcriptional regulatory mechanisms. In a second line of research we apply the ancestral sequence resurrection methodology to plant related questions such as the origin of hormone signaling, the origin of flowers and the impact of whole genome duplications.
