PLANT SIGNAL RESEARCH GROUP

A MOLECULAR BIOLOGY LAB IN ESTONIA

 
 

Meet The Team

Hannes Kollist

Professor of molecular plant biology

I am fascinated in researching mechanisms by which guard cells integrate information from outside as well as inside the leaf to adjust plant gas exchange. I am also excited in developing technologies that allow studying plant behavior in various growth conditions.

Ebe Merilo

Senior research fellow

My research focus is on stomatal regulation of model plants and crops. The interplay between water loss and leaf cooling which both depend on stomatal conductance is risingly important in terms of grain yield as well.

Joachim M. Gerhold

Senior research fellow

My major interest lies on biochemistry of organelles, especially mitochondria, their metabolism, and related protein interactions. I am fascinated about the synchronisation and signalling between the different organelles like e.g. the ER and mitochondria or chloroplasts and mitochondria.

Bahtjor Rasulov

Senior research fellow

I have headed the construction of over 10 unique gas-exchange systems for  the study of physiological and biochemical processes in higher plants. Within past 11 years, my research interests  include the study of the mechanisms of biochemical regulation of photosynthesis and secondary metabolism.

Yuh-Shuh Wang

Senior researcher

I’m interested in studying gene functions underlying particular phenotypes. I enjoy designing and assembling gene constructs for plant transformation, including those for plastid transformation and genome editing.

Dmitry Yarmolinsky

Senior research fellow

I have done a long way from my PhD studies of thyroid cancer, research of plant sulfur metabolism to our current project on identification of new stomatal  regulators. I am interested in roles of stomatal signaling in plant adaptation to ever-changing environmental conditions.

Ashutosh Pandey

Post-doctoral fellow

My research interest includes study of impact of changing climate on different crop plants  e.g. high ozone, CO2 and ABA in single and in combination. Currently,I am interested in stomatal behaviour and signalling pathways in ozone-sensitive mutants in guard cells under different abiotic stress.

Maris Nuhkat

Junior research fellow

I am interested in the responses of plant membranes to abiotic environmental stimuli, specifically the effect of tropospheric ozone and variations in carbon dioxide concentration on the workings of proton pumps and anion channels, as well as calcium signalling.

Olena Zamora

PhD-student 

I am involved in the project that is aimed at the identification of new components in O3/ROS-induced stomatal closure. In addition, I am interested in studying roles of plant hormones in adaptation of stomatal aperture to environmental conditions.

Koit Aasumets

 PhD student

I am studying the mechanisms of human mitochondrial genome (nucleoids) maintenance in dynamic mitochondrial network. This includes studying the physical connections between ER-mitochondria that seem to an important role in these processes.

Mikk Välbe

Lab assistant 

I assist. I have the best job in the lab, because I am involved in almost everything happening in the lab and I enjoy that versatility.

  • link-icon

I have a long-term experience in the development of the scientific instrumentation. To me is a big challenge to find solutions, and get accurate measurement data in all conditions.

Roman Leinus

Liina Jakobson

Research fellow

During my Master’s studies I fell in love with the most important organisms on our planet - the plants. I enjoy microscopy work, precise pipetting such as qPCR and everything else related to plant biology studies. I also like to be organised and to manage different projects.

Currently I am interested in stomatal physiology, the methods that enable to measure related traits in whole plant context (gas exchange, thermal imaging, chlorophyll fluorescence imaging) and the interactions of signalling pathways controlling stomatal development and movements.

Hanna Hõrak

Research fellow

My research is focused on factors that regulate plant water economy. I study natural variation in the stomatal response to elevated CO2 concentration, which is predicted to have a large impact on plant water use in a future climate. Recently I have also become interested in cuticle formation, which is an important process for the development of more drought-tolerant plants.​

Jenni Katri Pedor

Master's student

I am studying the regulation of proton pumps involved in stomatal signaling.
