[2019-03-25] The Knut and Alice Wallenberg Foundation announced today the names of 22 new Wallenberg Scholars. Markus Schmid, group leader at UPSC and professor at the Department of Plant Physiology, Umeå University, is one of them. He receives a five-year grant that he can invest for his research without any restriction.

Markus Schmid works on the regulation of flowering time. He wants to understand which environmental factors are influencing the plant’s decision to start to flower and how this is regulated in the plant. In the project, that was now approved by Wallenberg, Markus Schmid will focus on the effect of temperature fluctuations not only on flowering but generally on plant growth and development.

“It is a great honour to be appointed Wallenberg Scholar. It gives me and my group security for five years so that we can really focus on our research,” says Markus Schmid. “This project was inspired by observations we made when I was still working in Germany several years ago.”

Then, Markus Schmid and his colleagues had found a mutant of the model plant thale cress (Arabidopsis thaliana) that grows normal at 23 degree Celsius but shows strong developmental defects when grown at 16 degree Celsius. Now they not only want to understand the molecular mechanisms that are underlying this defect but also what controls plant development in response to changing temperatures in general.

“In contrast to most animals, plants have the ability to grow new organs throughout their entire life. Where a new organ is formed is to a large extent genetically determined. However, the growth of the new organ and its final shape is influenced by many environmental signals including temperature”, explains Markus Schmid. “This “phenotypic plasticity” allows plants to adapt fast and flexible to changes in their environment and ensures their survival.”

Markus Schmid will work in this project with the model plant thale cress. He will focus on special tissues, called meristems, that harbour plant stem cells. All new organs derive from those stem cells that are slowly dividing and differentiate to form the specific organ. Markus Schmid and his group want to study how this process is affected by temperature and they want to identify the genes that are involved in this process.

“Markus’ research is very fundamental and will be useful for agriculture and forestry to develop new plant varieties that can cope with a changing climate”, says Ove Nilsson, director of UPSC and since 2013 Wallenberg Scholar. “We are delighted for Markus and that UPSC now has another Wallenberg Scholar. I am myself a Wallenberg Scholar and as a scientist it is the best grant you can have in that it gives you a lot of freedom to pursuit the research where your curiosity leads you”.

The Wallenberg Scholar programme is directed to senior researchers located in Sweden. The funding shall enable them to focus on their research without the pressure of attracting funding. The money can be freely used for the research without any restrictions. After five years, the research of the Wallenberg Scholars will be evaluated and the best ones could get a further extension of the grant for five more years.

[2019-03-14] Barbara Terebieniec, PhD student at the Department of Plant Physiology, wanted to identify the factors that determine the shape of a leaf. Using different systems biology approaches, she and her colleagues identified genes that are controlling leaf shape in European aspen. Barbara Terebieniec successfully defended her PhD thesis today at Umeå University.

Why did you choose your project?

I was interested in working with populations and phenotypic traits and leaf shape is one of the most obvious characteristics of the plant phenotype.

What was most fascinating during your PhD?

I was collecting buds throughout the summer and cross-sectioned them to prepare them for the microscope. Like this, I could follow the full development of a leaf from the start until the bud flash under the microscope. That was very fascinating to see.

What was most disappointing during your PhD?

In collaboration with SciLifeLab, we developed and optimized the Spatial Transcriptomics (ST) method for our poplar bud samples. After we successfully optimized the ST method for our bud samples, we realized that the current resolution of this technique for plant samples is too low for the tiny buds. So, we could not answer all our questions even though we achieved what we planned in this project.

What do you like about UPSC?

UPSC with all the people from different countries creates this nice multicultural bubble. I met many nice people and made lots of new friendships.

What are your plans for the future?

Two years ago, I started working on my own start-up. I was very frustrated about keeping track of my lab samples in commonly used -80°C freezers. Our idea was to develop FreezFiler, a digital, non-intrusive system using computer vision. It can be placed on the -80°C freezer to read barcode tagged samples and simplifies the inventory of the freezers. We are now on the way to register a company and launch our first product. It means a lot of work, but also a lot of excitement and I am looking forward for these new challenges.

About the PhD thesis

Barbara Terebieniec and her colleagues exploited several different bioinformatics approaches to identify genes that are controlling leaf shape. Their results show that leaf shape is controlled by a complex network of many different genes and that each of those genes contributes minorly to the final leaf shape.

They compared the genetic setup of a collection of aspen trees with different leaf shape and identified genes that are associated with leaf shape. In a next step, they showed that a number those genes also play a role during leaf development. For this, they compared the genetic setup of leaves of different age, developing on one individual tree.

In an additional approach, Barbara Terebieniec optimized successfully the method spatial transcriptomics for aspen buds together with researchers from SciLifeLab. With this technique they hoped to identify those genes that are specifically expressed in the developing leaf within the bud. Even though they successfully established the method, they could not resolve spatially which genes were active during leaf development in the very young leaf because the size of the tissue was too small for the technique.

About the defence:

Barbara Terebieniec defended her thesis entitled “Using systems genetics to explore the complexity of leaf shape variation in Populus tremula” on Thursday, 14th of March. The public defence took place at 10:00am in Lilla hörsalen (KB.E3.01) in the KBC building, Umeå University. Faculty opponent was Chung-Jui Tsai from the Department of Genetics, University of Georgia, USA. Supervisor of the PhD thesis was Nathaniel Street.

SPPS prizes 2019 1920x1080The three SPPS awardees from UPSC (from left to right): Åsa Strand, Torgny Näsholm and Karin Ljung (Photo: Anne Honsel)

The council of the Scandinavian Plant Physiology Society (SPPS) has selected the winners of the SPPS Prizes 2019. Three of the seven awardees are affiliated with the Umeå Plant Science Centre. Karin Ljung receives the SPPS Prize, Åsa Strand the Physiologia Plantarum Prize and Torgny Näsholm receives the SPPS Innovation Prize together with Barbara Halkier from the DynaMo Center at the University of Copenhagen.

SPPS is awarding biannually six prizes to acknowledge scientists, located in one of the Nordic countries, for outstanding achievements in plant sciences. Karin Ljung, group leader at UPSC and professor at the Swedish University of Agricultural Sciences (SLU), is receiving the SPPS Prize for her extensive and significant contributions to plant science. She started her own group at UPSC in 2005 and is now for five years in a row acknowledged as one of the Highly Cited Researchers by Clarivate Analytics. Her research focusses on root growth and development and the role of plant growth substances in these processes.

The Physiologia Plantarum Prize goes to Åsa Strand for her recently published ground-breaking work. Åsa Strand, also UPSC group leader and professor at Umeå University, wants to understand how the chloroplasts and mitochondria communicate with the nucleus. Her group identified in one of her recent publications in the journal Nature Communications a new molecular link that synchronizes gene expression in the chloroplast and the nucleus during seedling development in response to light. The Physiologia Plantarum Prize is the only SPPS prize that is open to all researchers world-wide and not only to SPPS-members.

The SPPS Innovation Prize honours scientists who manage to transfer their basic plant research into practical applications. Torgny Näsholm, associated group leader at UPSC and professor at SLU, and Barbara Halkier, professor at the University of Copenhagen and head of the DynaMo Center, are sharing the prize this year. Torgny Näsholm demonstrated that trees use amino acid molecules as nitrogen source. His findings led to the development of new fertilizers. Barbara Halkier and her group are working on plant-specific substances that are serving for example as defence compounds. Based on their results, they have together with Bayer Crop Science developed a new, more resistant oilseed crop.

The other three awards go to Jens Sundström and Charles Melnyk, both from the Swedish University of Agricultural Sciences (SLU) in Uppsala, and to Moona Rahikainen from the University of Turku. She receives the SPPS Best PhD thesis prize. Jens Sundström receives the SPPS Popularisation Prize, a prize that awards public engagement for plant research. Charles Melnyk gets the SPPS Early Career Prize to honour the significant progress he made in setting up his independent research group. The awards are officially handed over in the biannual SPPS Congress that will be held this August in Umeå.

The Knut and Alice Wallenberg Foundation approved large projects on tree research. SEK 180 million will be invested for research on tree genes, forest biotechnology and forest genetics. The projects involve a collaboration between UPSC and the Science for Life Laboratory.

The projects are coordinated by Ove Nilsson, director of UPSC, and Ulf Gyllensten from Uppsala University. The first project aims to identify new genes that control growth and wood formation in trees. Part of this project is based on a fully automated phenotyping platform that is established at UPSC. Hundreds of trees can be grown on conveyor belts at this platform and their growth and other properties are automatically measured. This platform is so far unique for dedicated tree research.

The other project has a focus on genomics and forest genetics and will follow up on the large project that led to the first mapping of a conifer tree genome, the Norway spruce genome. That previous project was also funded by the Knut and Alice Wallenberg Foundation and was as well a collaboration between UPSC and the Science for Life Laboratory. In the new project, an updated and significantly improved version of the spruce genome will be developed. In parallel, the genome of Scots pine will be sequenced.

Moreover, genetic variations in the genome of thousands of spruce and pine trees that are linked to the Swedish coniferous breeding programs will be analysed. This will provide important basic research tools to understand the trees' natural variation and allow the development of new efficient tools for tree breeding, so-called genomic selection. This part of the project takes place in close collaboration with the Forestry Research Institute of Sweden (Skogforsk).

The projects are approved together with another project on forest production and forest management at the Swedish University of Agricultural Sciences (SLU) that is coordinated by Tomas Lundmark. The latter project will ensure that the entire potential of the genetics project and the latest breakthroughs in plant nutrition research are further exploited and developed. With the support of new digital technology, forest growth will be enhanced by increasing the diversity in forestry. The idea is to combine the right plant with the right forest management action at the right place to get the best growth-enhancing effect.

Forest management programs will be developed by utilizing the latest basic research on how tree growth is affected by ecophysiological factors such as nutrition and water, how trees collaborate with fungi and microorganisms and on the effect of tree competition, not least under the ground. The aim is to at least double the growth increase that is reached today. With enlarged availability of renewable forest raw materials, the forest can further contribute to the growing bioeconomy and mitigate the effects of climate change.

[2018-12-13] The Swedish Research Council announced the new members of its board and of its scientific councils. Åsa Strand, professor at UPSC, is one of the nine members of the Scientific Council for Natural and Engineering Sciences. Her mandate is for three years (2019-2021).

The Swedish Research Council is a government agency within the Ministry of Education and Research that fund research and research infrastructure in all scientific disciplines. The council also has an advisory role to the Government on research policy issues and work to increase understanding of the long-term societal benefits of research.

The new members of the Scientific Councils are elected by an election assembly that is formed by representatives from the Swedish higher education institutions. In total, 165 electors are selected to appoint the new members of the three Scientific Councils and also the members of the board of the Swedish Research Council.

[2018-12-12] Sacha Escamez receives this year’s UPSC Agrisera Prize. The award was announced today during the traditional UPSC Christmas lunch. Sacha Escamez is awarded for his scientific achievements and engagement in scientific discussions at UPSC and for his valuable contribution in upgrading the UPSC microscopy platform. The prize values that Sacha Escamez’s diverse commitments helped to improve UPSC’s work and social environment.

Sacha Escamez successfully carried out research on the regulation of lignification and cell death during xylem development first as a PhD student and now as postdoc in Hannele Tuominen’s group. He actively participates in and encourages scientific discussions at UPSC and also promoted his research in a public science talk for the Swedish television last year.

This year, he invested a lot of time in upgrading the UPSC microscopy platform by collecting the requirements and wishes from his colleagues, testing out different systems and negotiating with the companies. He is taking on a key role in setting up single molecule detection methods that can be done with the new instrumentation at the UPSC microscopy platform, and he will help to introduce users to those new methods.

The UPSC Agrisera Prize is awarded every year to a PhD student, Postdoc or technician at UPSC for excellent scientific achievement and positive contributions to improve the UPSC working environment. Four nominations were sent in by Sacha Escamez’s colleagues for the UPSC Agrisera Prize this year. Sacha Escamez’s nomination stuck out because it emphasized not only his scientific achievement and encouragement for the microscopy platform but also his social engagement (e.g. by creating the UPSC innebandy team) to make UPSC a nice place to work at.
