Kort presentation

Evolution of plant developmental mechanisms

By using mutants, gene expression studies and other molecular tools we study the differences and similarities in how land plants, separated by several hundred million years of evolution, regulate growth and development in response to environmental factors, such as light and temperature.

My plant science career started in 2002 with a master's project in the lab of Dr. Johan Edqvist at Department of Plant Biology, Swedish University of Agricultural Sciences (SLU), Uppsala. I was accepted as a PhD student in 2003 in the lab of prof. Eva Sundberg (plant physiology), SLU, and six years later I defended my thesis on the regulation of auxin synthesis in Arabidopsis and the moss Physcomitrella. Subsequently, I started a postdoc in the lab of prof. Benedikt Kost (molecular biology), SLU working on Rac/ROP GTPases in pollen tubes of flowering plants and filaments/rhizoids of Physcomitrella. Between 2011 and 2014 I did a postdoc financed by the Swedish Research Council VR and the Australian Research Council in the lab of prof. John Bowman (plant development and evolution) at School of Biological Sciences, Monash University, Melbourne, Australia. This is where my current work on developmental biology of the liverwort Marchantia started. I returned to Sweden and the Evolutionary Biology Centre at Uppsala University as a researcher in the Lagercrantz lab in 2014. From 2017 I am heading my own research group focusing on the evolution of mechanisms regulating development in plants.

The biology of Marchantia polymorpha and related liverworts has fascinated botanists for centuries, providing a rich literature describing both phenomenology and pharmacological experiments. With the advent of Marchantia as a model genetic system, we are now in a position to begin to elucidate the molecular genetic mechanisms by which its architecture, development and growth is regulated. We are tracing the evolutionary history of genetic programs for dormancy regulation initially identified in seed plants by examining them functionally in Marchantia. We are also screening for novel dormancy regulators. Dormancy was a key adaption to facilitate survival in terrestrial environments, enabling seasonal growth. Understanding dormancy regulation in liverworts will aid efforts to decipher the evolution of dormancy leading to the adapted forms seen in flowering plants. Marchantia is emerging as a powerful model species. This unique plant appears to possess attributes retained from the earliest land plants, it has low genetic redundancy, and many molecular tools are available, including a sequenced genome likely to be published later in 2017.

In the long term, this project poses two interrelated questions: 1) how similar are the genetic programs for developmental processes in evolutionarily distant plants, and 2) how can we exploit the simplicity of the Marchantia model system to help decipher the complexity of flowering plants? We are studying the differences and similarities in dormancy regulation between the liverwort Marchantia and seed plants such as Arabidopsis. This involves examination of genetic and hormonal pathways for phytohormones such as auxin and abscisic acid, and will lay a foundation for the discovery of previously uncharacterized evolutionarily conserved components regulating plant development.

A detailed understanding of plant development is of great importance not only for basic sciences - knowledge about the integration of genetic and developmental pathways is also critical to facilitate the precise design of plants for diverse agricultural applications. The specific aims of this project are to: 1) Identify and characterize the interaction between different hormonal pathways for dormancy regulation in Marchantia, 2) and to identify and characterize novel regulators of dormancy in land plants.


This project is a collaboration with prof. Ulf Lagercrantz, IEG, Uppsala University. For more info see our recent publication "Early evolution of the land plant circadian clock" Linde et al., 2017, New Phytologist.
