We study two major aspects of plant development: how it is shaped by spatiotemporal patterns of hormone signaling, and what are the ultimate cellular functions activated by hormones that lead to cell fates as disparate as proliferation, elongation or degeneration.
We are performing comparative studies between the perennial Arabis alpina and the annual Arabidopsis thaliana to understand the molecular mechanisms that drove life strategy evolution within the Brassicaceae.
We investigate molecular processes and proteins involved in transport of metabolites through cellular membranes. By this we aim to improve plant disease control and to increase crop yield of maize and rice.
We investigate the genetic basis of phenotypic differences between the emerging model species Cardamine hirsuta and its relative Arabidopsis thaliana and examine the evolutionary processes underlying such differences. We focus on petal number variation and explosive pod shatter, which are traits found in C. hirsuta but not A. thaliana,and use parallel genetic studies to investigate the evolution of developmental processes controlling these traits.
