Research areas

Plants as sessile organisms must adapt to ever changing environmental conditions. The adaptations to environmental cues are essential for plant survival and consequently for crop productivity. The adaptation processes rely on sensing and transduction of environmental signals, integration of various forms of signals and determination of the final response. Plant hormones are implicated in various aspects of regulation of plant development, growth and responses to environmental cues. Our work is focused on systematic analysis of environmental and hormonal signaling in regulating plant growth and development, as well as adaptation to environmental cues.

We focus on how different environmental and endogenous signals are integrated into the subcellular dynamics and polar localisation of transporters for plant hormone auxin. We expect to get a deeper knowledge on plasticity of plant responses to environmental cues.

Main objectives

1. Plant hormonal signalling for regulation of cell polarity and subcellular dynamics:

Identification of key entry points by which auxin and other signalling pathways modulate subcellular dynamics and polar trafficking of PIN auxin transporters

2. Cell polarity and subcellular dynamics in plant cells:

We elucidate molecular and cellular mechanisms underlying cell polarity and trafficking processes by combination of genetics and high resolution microscopy approaches.

3. Perception of external signals and their integration into subcellular dynamics and cell polarity:

Using combination of reverse genetic, chemical genomics, life cell and high-resolution imaging approaches; we gain new insights into how gravity and light perception is integrated into regulation of subcellular dynamics.

4. Integration of hormonal signalling and subcellular dynamics for multicellular tissue development by mathematical modelling:

The acquired knowledge on hormonal networks; processes of subcellular dynamics and integration of different signals will be used to mathematically model these processes and to extrapolate them onto multicellular developmental situations.

1. Evolution of auxin transport and cell polarity mechanisms in plant lineage

Supervisor: prof. Jiří Friml, Dr.


Plant development is characterized by a remarkable adaptability to different environmental conditions. Plants have the flexibility to re-organize post-embryonic development through regulation of asymmetric distributions (gradients) of the plant growth regulator auxin. Auxin is unique among plant signaling molecules, because it is polarly transported through plant tissues and its transport largely depends on subcellular localization of auxin efflux carriers – PIN proteins. Our lab aims to understand mechanisms of PIN polarization and auxin-mediated plant morphogenesis using experimental and theoretical approaches. This PhD project focuses on how the unique, plant-specific mechanisms of auxin transport and polar trafficking appeared and evolved in the plant lineage. The project will involve a combination of molecular genetic, cell biological and biochemistry techniques in early diverging plants such as moss Physcomitrella patents and filamentous algae as well as in the model plant Arabidopsis thaliana. We expect: Highly motivated candidates with ambition of producing relevant top results. We offer: Experimental work on own project with the possibility of publication in top international journals, world-class lab equipment, international cooperative team, close cooperation with abroad laboratories, competitive salary corresponding to the work efficiency.

2. Biochemical and structural insights into PIN-mediated auxin transport

Supervisor: Tomasz Nodzynski, B.A., M.Sc., Ph.D.
Consultants: Prof. Jiří Friml


The signalling molecule auxin provides instructive cues guiding the entire plant ontogenesis. Its orchestrating role largely depends on the directional transport between cells facilitated by a plant-specific group of auxin transporters named PINs. While the physiological and developmental roles of PINs along with their intracellular dynamics have been extensively studied, the biochemical and structural underpinnings of PIN activity are only scarcely characterized. Proposed research aims to fill this gap providing a detailed biochemical characterisation of auxin transport, including PIN structure-function aspects responsible for transport and auxin binding specificity. Obtained results will be described using mathematical models allowing for more accurate results interpretation and detailed linking of PIN biochemistry and function. Our findings have also a clear application potential to engineer auxin-based aspects of physiology and architecture in the important plant species as well as help in the development of new auxin derivatives applicable as modern tools in crop cultivation.
