During the SPPS Congress at Elite Hotel Mimer (photo: Anne Honsel)
[2019-09-02] Last week, the SPPS (Scandinavian Plant Physiology Society) Congress took place at Elite Hotel Mimer in Umeå. During three days, members of the society discussed actual topics in plant physiology, several prizes were officially handed out and the society held its General Assembly and elected the new SPPS Council. A special highlight during the conference was the technically advanced excursion to the Field Research Site “Rosinedal” that was even mentioned in the local newspaper.
The Scandinavian Plant Physiology Society is organising every second year its main meeting, the SPPS Congress. The focus of this international meeting is on exchanging and discussing knowledge about actual topics within the field of plant physiology. Internationally renowned researchers in the field are invited to present their research in parallel to Scandinavian plant physiologists. During the general assembly of the society, the new council was elected with Christiane Funk, Professor at the Department of Chemistry at Umeå University and associated group leader at UPSC, as new president.
During the congress, SPPS handed out six different prizes to award outstanding achievements of plant scientists, located in one of the Nordic countries. Three of this year’s awardees are affiliated with the UPSC: Karin Ljung was awarded with the SPPS Prize, Åsa Strand with the Physiologia Plantarum Prize and Torgny Näsholm received the SPPS Innovation Prize together with Barbara Halkier from the DynaMo Center at the University of Copenhagen (for more information about the prizes read also here).
In the afternoon of the second day, participants of the congress were visiting the Field Research Site “Rosinedal” that is located in a forest stand east of Vindeln. At this field site, researchers are studying in a long-term experiment the effect of nitrogen on the carbon balance of the forest. During the excursion, participants got an overview about the different studies that are made at “Rosinedal”. Via an QR-code, they could access additional information about the history of the field site and the research highlights. This technically advanced tour even motivated a local newspaper to write about it.

[2019-07-25] Today, on the anniversary of the decision of the Court of Justice of the European Union (CJEU) on plant breeding with the help of gen-editing, an open letter was sent to the Swedish European parliamentarians and the Swedish government. The letter is a call to action for an expedited change of the European legislation for genetically modified organisms (GMO). It has been signed by the leaders of 14 Swedish universities/research centres, royal science academies or research financiers as representatives of the independent Swedish research community.
“The decision of the European Court of Justice has such far-reaching consequences for research and for a more sustainable and environmentally friendly agriculture that the Swedish science community found it necessary to react strongly to try to achieve a change in legislation”, says Stefan Jansson, professor at Umeå University, who coordinated the letter.
Read the open letter (English and Swedish):

Scots pine is one of the most commercially used tree species in Sweden. To be able to breed lines with improved growth, survival and properties is of great interest for tree breeders and the forest industry. Unfortunately, the tree breeding cycle of Scots pine lasts between 20 to 30 years and that causes that the evaluation of trees in breeding trials requires several years. In her PhD project Ainhoa Calleja-Rodriguez successfully evaluated new statistical methodologies that can aid to reduce the breeding cycle in the future and to improve the accuracy of the genetic parameters on growth, adaptive traits and wood quality traits of Scots pine. She successfully defended her PhD on Wednesday, 29 may at SLU Umeå.
In her study Ainhoa Calleja Rodríguez evaluated different families of Scots pine in several locations all over Sweden. Geographical variation was important as the environment has big impact on the behavior of the trees and with a new statistical method, called factor analysis, she was able to evaluate more characters simultaneously. Another new method called genomic selection was applied for the first time on Scots pine. Ainhoa showed that it may be possible to evaluate trees already at the seedling stage but also gives more accurate estimations of genetic variation of growth and wood quality traits then traditional methods.
Ainhoa was a student of the UPSC industrial graduate research school of forest genetics, biotechnology and breeding. Therefore, she was doing her PhD project not just as student at the department of forest genetics and plant physiology at SLU but also partly at the Swedish forest research institute Skogforsk, which has one main working focus on tree breeding.
Why did you choose your project?
I felt in love with tree improvement through a previous job experience as research technician and also from my master thesis in Spain, so when a colleague in Spain sent me the announce of this position in Sweden, I just did not doubt a second to send my application.
Did the fact that this PhD program you were in was located both in industry and academia influence the decision of starting on it?
Yes, it did, specially the industry part was essential for me to decide about this position. The fact that 20% of my time could be expend as internship at the host company (Skogforsk in my case), and be in direct contact with the operational breeding program and with the tree breeders, it was what made me decide for this PhD position.
What was most fascinating during your PhD?
The most fascinating was the opportunity of being Industrial PhD Student at the Second Research School of Forest Genetics, Biotechnology and Breeding, because it gave us the opportunity to attend PhD courses with the top professors in quantitative genetics and breeding, as well as to have a “field trip” to visit the most advanced breeding programs in USA and Brazil. Also, performing my internship within Skogforsk was also fascinating, especially because at the end one of the projects became part of the thesis and was key to improve my knowledge of quantitative genetics, linear mixed models and ASReml (the most common software used in plant and animal breeding).
What was the most disappointing experience you had during your PhD?
It was really hard to get good quality marker data for Scots pine. First time we tried, it took more than a year and half to get some data and finally their quality was not enough to use them, so the part of genomic prediction of my thesis was delayed. Fortunately when we tried the second time it did not take that long and we finally could use them.
What are your plans for the future?
Last month I had an interview and got a new job at Skogforsk as researcher, so I am finally going to work with the scientists there in the operational breeding program

[2019-05-21] On Saturday, 18th of May, the 5th Fascination of Plants Day was celebrated in Umeå with a public event. Almost 300 visitors came to Kafé Fika at Väven and got involved in many different activities around plants and plant science.
What colours are hidden in the leaves of plants? Why are the interactions between plants and insects so important? What are microalgae and how can they be used? The visitors were invited to hands-on activities around those and other topics. They could isolate DNA from strawberries, prepare seed bombs and learn more about how to grow mushrooms.
The aim of the Fascination of Plants Day is to fascinated people for plants and to generate awareness for the importance of plant science. It was launched under the umbrella of the European Plant Science Organisation (EPSO) and was first organised in 2012 on a European level but is now internationally celebrated. This year more than 800 events across 51 countries were organised.
The event in Umeå was organised by scientists from the Umeå Plant Science Centre, the Department of Chemistry, the Department of Ecology and Environmental Sciences, both from Umeå University, the Department of Forest Ecology and Management, Department of Forest Biomaterials and Technology, the Department of Agricultural Research for Northern Sweden, all three from SLU, by Skogforsk, the Forestry Research Institute of Sweden, the Swedish Bonsai society (Bonsaisällskapet) and the Broparken gardening project.

[2019-05-21] Thi Hai Hong Nguyen analysed how genetic variation influences wood and oil quantity and quality in Norway spruce and Melaleuca, a multi-purpose tree distributed in Australia, Papua New Guinea and South-East Asia. In her Phd thesis, she recommends tree breeding strategies for the two species to optimize their industrial usage. Thi Hai Hong Nguyen successfully defended her PhD thesis on Friday last week, 17th of May 2019.
Do trees that grow faster have lower wood quality and contain less oil or oil of lower quality? Is it better to use only one clone of a species in forestry or can it be of advantage to plant families, that means related trees that do not contain the exact same genetic composition? The answers to those questions are of high interest for the forest industry. Thi Hai Hong Nguyen estimated in her PhD thesis the genetic parameters that influence wood and oil quality and quantity and looked into the effect of genetic variation of Melaleuca and Norway spruce. Based on her results, she gives advices for tree breeding strategies for the two species.
The public defence took place in P-O Bäckströms sal at SLU Umeå on Friday, 17th of May 2019. Faculty opponent was Prof. Steven E. McKeand from the Faculty of Forestry and Environmental Resources, NC State University, USA. The supervisor was Harry Xiaming Wu.

Kungliga Skytteanska Samfundet, a scientific academy based in Umeå, hands out every year prizes for outstanding research and cultural commitment. This year, Ioanna Antoniadi, researcher at the Umeå Plant Science Centre, will receive the prize that is assigned to the Faculty of Forest Sciences from SLU.
Ioanna Antoniadi focusses in her research on root development and the role of plant growth factors that are controlling the development. Kungl. Skytteanska Samfundet valued in their motivation for the prize, that Ioanna Antoniadi contributed to an improved understanding of mechanisms that regulate growth and development of plants, a fundamental knowledge with potential application within plant cultivation.
After finishing her PhD at the Imperial College in London, Ioanna Antoniadi moved to Umeå in 2015. She started in the group of Karin Ljung at the Umeå Plant Science Centre, first as a postdoc and now as a researcher. She has published as author or co-author six scientific publications within the last five years and became the expert at UPSC for Fluorescence Activated Cell Sorting (FACS), a very advanced technique that allows detections on the single cell level.
Ioanna Antoniadi independently developed and optimised new methods based on the FACS technique. She could demonstrate that the plant hormone cytokinin forms a gradient in the root tip of the model plant Arabidopsis thaliana, with the highest concentration in the top. These results were published in the prestigious journal Plant Cell and are now well cited. She also contributed to studies about how plants react on the hormone level to different type of stresses, e.g. salt stress and mechanical stress.
Kungl. Skytteanska Samfundet is awarding in total six prizes to young researchers, a cultural prize, the “Margareta och Eric Modigs” prize that is assigned to the Medical Faculty of Umeå University, a prize for a young artist from the Umeå Academy of Fine Arts, a prize for a young musician from the School of Music in Piteå and the “Samfundets stora pris”. All prizes will be officially handed over at the societies “Årshögtiden” on Friday, 24th of May at Sävargården in Umeå.
About Fluorescence Activated Cell Sorting (FACS):
Cell sorting is a method that allows purification of highly specific cell populations from a mix of cells. It can be for example used to isolate scarce cell types, that are labelled with a fluorescence marker, from a plant tissue. The plant tissue is initially enzymatically digested to remove the cell walls which leads to the formation of protoplasts (plant cells that are surrounded only by the plasma membrane). The protoplast mixture is then loaded into the FACS instrument that acts as an extremely “sharp knife” sorting the cells according to their size, internal complexity and fluorescence. The sorted and isolated cells can then be used for further analyses in downstream applications.

The new Wallenberg Scholar Markus Schmid (photo: Anne Honsel)
[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.
