Benkova Group

Plant Developmental Biology

True to their name’s Greek roots, plant hormones “set in motion” a myriad of physiological processes. Influencing and modulating each other, an intricate network of interactions arises. The Benková group seeks to untangle this network and understand its molecular basis.


Plants as sessile organisms constantly integrate varying environmental signals to flexibly adapt their growth and development. Local heterogeneities in water and nutrients availability, sudden changes in temperature, light or other stresses trigger dramatic changes in plant growth and development. Multiple hormonal signaling cascades interconnected into complex networks act as essential endogenous translators of these exogenous signals in plant adaptive responses. How the hormonal networks are established, maintained and modulated to control specific developmental outputs is the focus of the Benková group. Recently, the group has located several convergence points that integrate different hormonal inputs. Importantly, some of these identified components exceed their function in the hormonal crosstalk and provide functional links with pathways mediating perception of environmental stimuli.
