Olivier Keech 151127 141033 JGS IG Webb 1920x1080
The Scandinavian Plant Physiology Society (SPPS), announced last week that Olivier Keech, assistant professor at Umeå University and group leader at UPSC, receives the SPPS Early Career Award 2017. This award honours young scientists in Scandinavia who proceed well in their scientific career and contribute significantly and independently to plant biology.

Olivier Keech established his research group in 2014 when he became assistant professor at the Department of Plant Physiology, Umeå University. His research focuses on the regulation of metabolism in response to abiotic stresses, notably in response to stress-induced senescence. Olivier Keech wants to understand why and how plants “decide” to sacrifice an organ such as a leaf for the benefit of the rest of the plant. He wants to know how this decision is communicated within the plant body and how the associated metabolic changes, e.g. the recycling and reallocation of valuable nutrients, are regulated.

There were all together four SPPS Award Winners announced by SPPS last week. The SPPS Award goes to Michael Broberg Palmgren from the Department of Plant Environmental Sciences, University of Copenhagen. Chuanxin Sun from the Department of Plant Biology, Swedish University of Agricultural Science in Uppsala receives the Physiologia Plantarum Award and Kurt Fagerstedt from the Department of Biosciences from the University of Helsinki the SPPS Popularisation Prize. All awards are monetary rewards as well as invitations to the SPPS Congress this summer in Naantali, Finland, where the certificates will be officially presented to the winners.

For more information about the winners and the awards please have a look on the SPPS homepage.

Mycorrhiza-project_1920x1080Group picture with the students from Dragonskolan who participated in the Mycorrhiza project, Sabine Kunz (2nd from left in the front row), Elisabeth Uppsäll (5th from left in the front row) and Judith Felten (1st from right in the first row)

[2017-03-24] Today, twenty students from Dragonskolan presented their results from the “Mycorrhiza project”, a six-month project together with Judith Felten’s group from the Umeå Plant Science Centre (UPSC). The project aimed to teach scientific methodology based on the interaction between mycorrhizal fungi and plant roots.

Do forest trees grow better when their roots are growing in interaction with mycorrhizal fungi? How do those roots look like? How many different fungal species are growing in forest soils and how can we detect them? These were questions the students tried to find answers to. Sabine Kunz, postdoctoral researcher at the UPSC, and Judith Felten, assistant professor at the Swedish University of Agricultural Sciences, developed this project in collaboration with Dragonskolan.

“We designed the project together with the biology teacher Elisabeth Uppsäll from Dragonskolan in Umeå. Our idea was to bridge the gap between biology lessons at school and scientific research,” says Sabine Kunz. “The students got access to specific scientific methods we are using for our research and gain insight into our work as researchers. There are many things you need to consider when planning experiments. This is best experienced when you do the experiment yourself and evaluate your results.”

“It has been great for us to participate in this project”,Students greenhouseStudents working with fir trees in the greenhouse (Photo: Sabine Kunz)adds Elisabeth Uppsäll. “It is important to get students to understand how scientists work and what methods are used to answer scientific questions. Sabine has been an invaluable link between the students and the UPSC because she is not only researcher but has also experience with teaching at school and she knows how to address students. We have had many nice meetings developing this project and exciting discussions during the full course of the project, weather we were digging up roots in nature or during the final seminar today.”

The students worked in smaller groups with different research questions. They went into the forest and dug up roots and soil and brought it to the lab. There, they used among others, DNA analyses to detect different fungal species in the soil. They tested whether young spruce trees grow differently in forest soil that contained mycorrhizal fungi than spruce trees in commercial planting soil. They observed roots from the forest under the microscope and they investigated whether the architecture of the plant root system changes when it is in symbiosis with the fungi.

“The mycorrhizal symbiosis is really fascinating. It is not visible until you dig up a root and look at it under the microscope but it is very important for the forest ecosystem,” says Judith Felten. “We hope that we could inspire the students by our project and that they now see the forest with different eyes.” 
 
After the experimental part, the students got a crash course in scientific data analysis. They learned how to edit a microscopic image, how to present data in diagrams and graphs and how to interpret results. They presented their results today in short talks to researchers and staff members of the UPSC.

The project was financially supported by the Kempe Foundations.

Vetenskapslunch2017 SJansson 1920x1080 2Vetenskapslunch February 2017 (Umeå University)
Stefan Jansson, plant scientist at the UPSC and Professor at Umeå University, was awarded the 2017 ÅForsk “Kunskapspris”. He is being honoured for his commitment to transfer scientific knowledge to the public.

The ÅForsk foundation awards every year “kunskapspriset”, a price that values
outstanding contributions to the dissemination of knowledge. Stefan Jansson was awarded this year with the following motivation:

“Stefan Jansson is a committed and untiring public educator who fights well and hard for knowledge. He is constantly active in the public debate, taking part not only in humoristic programmes but also in political debates. He informs about both his own and other’s research to school kids as well as to pensioners. He is active in bringing knowledge into the debate on GMO and organic farming to counteract fact resistance.”

“I feel incredibly honoured and glad”, says Stefan Jansson. “Actually, I think there should be more prizes that encourage researchers to use their knowledge in the public debate. It’s probably never been more important than at present.”

The candidates for the ÅForsk price are nominated by the Universities . One very prominent awardee was Hans Rosling, a Swedish role model in the debate on fact resistance who has received the price in 2006 but has recently passed away. “He has left great footsteps to follow in”, says Stefan Jansson. “very many like me will be needed to fill his shoes”.

Six researchers from UPSC developed a concept for more sustainable urban farming. They presented their idea last November at PLATSEN in Umeå, a conference that aims to bring together different actors to discuss about sustainable developments. A short video describing their so-called eMTE concept is now available online.

The concept called eMTE (electronic Multi-Trophic Ecosystem) comprises several stages of a food chain like aquaculture, compost recycling, bioreactors as well as aero-/hydroponics. These so-called trophic layers are electronically controlled and interconnected with each other to form a small-scale ecosystem. Like this, nutrients produced in one trophic layer can support another layer reducing the amount of waste and energy that needs to be invested to produce food. Employing electronics offers great possibilities to monitor the different trophic layers and therefore makes the entire ecosystem more modular, which thus eases its use within complex structures such as found in cities.schemeSchematic overview of the eMTE concept

The eMTE project was initiated by Olivier Keech, assistant professor at Umeå University. His team, namely Nicolas Delhomme, Simon Law, Stefano Papazian, Alonso Serrano, Bastian Schiffthaler and Bernard Wessels, consists of fundamental scientists with different specialisations. All of them are driven by the idea to improve urban farming and urban food production while in parallel increasing the awareness about human relationship to ecosystems.

“It was great to get the opportunity to present our eMTE concept at PLATSEN”, says Olivier Keech, leader of the eMTE project. “We got lots of positive feedback as well as new contacts to collaborate with, which is encouraging. Our idea is to develop this project further so it can be soon integrated into existing and novel urban farming projects.”

PLATSEN is thought as a platform where decision makers, politicians, scientists, NGOs and people from public and private sectors can meet and exchange and discuss ideas about sustainability in an urban environment. The event is initiated by the Swedish Scientific Council for Sustainability in collaboration with several other actors from the public and private sectors e.g. Umeå Municipality and Umeå University.

[2017-01-19] UPSC and SweTree Technologies announced today that they have entered into partnership with the VIB Center for Plant Systems Biology to accelerate research on tree value and productivity. The joint research collaboration aims to identify new genes for growth increase in trees and is envisioned to strengthen all involved parties. The study results will be published in leading scientific journals.

The joint project of Belgian and Swedish scientists builds on accumulated experience on functional genomics of genes controlling growth in annual plants as well as trees. This partnership combines four important assets: the strong research on tree biology and genomics at UPSC; the excellent industrial tree biotechnology capabilities of SweTree Technologies; the world-leading expertise in plant growth and productivity of the research group of Dirk Inzé (VIB-UGent); and the outstanding expertise in bio-informatics and comparative genomics of the lab of Klaas Vandepoele (VIB-UGent).

“This agreement will bring the UPSC and VIB research environments closer together, by exchanging researchers more frequently and by arranging joint scientific meetings”, says Ove Nilsson, director of UPSC. “We are very excited about this opportunity to deepen our scientific collaborations with the VIB Center for Plant Systems Biology, one of the strongest research environments in Europe for experimental plant research. It is an excellent complement to our research interests and we are especially excited about the possibilites to make cutting-edge comparative genomics analysis between Arabidopsis, maize and poplar trees.”

VIB and UPSC will share all data and develop new bioinformatics tools to identify key conserved regulators of growth and wood formation. “My team is passionate about understanding plant growth and how this is controlled by both intrinsic development programs and environmental cues”, says Dirk Inzé. “By using the experimental advantages of both Arabidopsis and maize as model systems we have made remarkable progress in understanding plant growth and crop yield. And we’re just getting started.”

In a first joint-research project, the researchers will test identified key genes for their growth and yield-promoting abilities in Arabidopsis, maize and poplar trees. SweTree Technologies will contribute to the collaboration with knowledge from tree plantations and they will test the best lead genes in Eucalyptus.

“We are delighted by the collaboration between UPSC, VIB and SweTree Technologies”, says Carl-Gustav Löf, CEO of SweTree Technologies. “With our joint efforts, we anticipate to take important steps towards significantly increasing the values of forestry plantations and agricultural crops.”

Sucrose delivers the carbon for cellulose biosynthesis. To make the carbon available, sucrose needs to be enzymatically cleaved. This can be done by two classes of enzymes, sucrose synthases and invertases. Umut Rende from Umeå Plant Science Centre (UPSC) investigated how these two enzyme classes contribute to cellulose biosynthesis in aspen wood. He will defend his PhD thesis at the Swedish University of Agricultural Science on Thursday, the 8th of December 2016.

Invertase TreesControl (WT) and different transgenic aspen lines with reduced invertase activity.Umut Rende has focussed specifically on sucrose synthases and cytosolic neutral invertases, enzymes that are active in developing aspen wood. By analysing transgenic aspen trees with reduced enzyme activity of either sucrose synthases or neutral invertases he could show that neutral invertases are important for cellulose biosynthesis. Sucrose synthase on the other hand is not delivering carbon specifically for synthesis of cellulose but also for other cell wall components like lignin and hemicellulose. 

The transgenic trees Umut Rende and his collegues created grew normally in the greenhouse without any visible differences to non-modified trees. “That was quite disappointing at first,” says Umut Rende. “The total neutral invertase activity in our invertase mutants was reduced by about 50%. We had to look deep into the chemistry and structure of the wood in these trees to see that the cellulose content and the diameter of the cellulose fibrils was reduced. This very specific cellulose defect demonstrated that neutral invertase activity is critical for cellulose formation in developing wood of hybrid aspen.”

Formas has recently granted two research projects from Umeå Plant Science Centre (UPSC) that both aim to analyse the specific role of carbohydrate metabolism for wood formation. Ewa Mellerowicz, coordinator of one project, will study the role of Carbohydrate Active Enzymes in wood formation. Totte Niitylä, who is leading the other project, aims to analyse how carbohydrates are transported and integrated into the wood. The two researchers from UPSC will each receive about three million SEK from Formas.  

A large proportion of the woody biomass arises from carbohydrates. The two projects will analyse the carbohydrate metabolism in developing wood in spruce and aspen. Both tree species are fully sequenced model species and important for the Swedish forest industry. The researchers aim to identify factors that control the mechanical and chemical properties of wood and that influence specific wood traits like volume and density which are interesting for forestry. The outcome of these projects will provide new insights into wood formation in trees and will be very interesting for spruce and aspen breeding programs in Sweden.  

Ewa Mellerowicz, Professor at the Swedish University of Mellerowicz Ewa 1150Agricultural Science (SLU), is focussing in her research on so called wood matrix polysaccharides. These are long-chained carbohydrates that interact with the other wood cell wall components, cellulose and lignin, to form a rigid structure. They are synthesized and modified by Carbohydrate Active Enzymes (CAZYmes) and affect the mechanical and chemical properties of cell walls in wood cells. In her project, Ewa Mellerowicz and her colleagues want to identify CAZYmes that are involved in wood formation in spruce where wood carbohydrate metabolism is so far not well studied.

The researchers specifically plan to characterize how the expression of the identified spruce CAZYme genes is changing during the day and how this influences the deposition of carbohydrates to the cell wall. In a further step, Ewa Mellerowicz and her team will test the function of the identified spruce genes in aspen. The identification and characterisation of spruce CAZYmes will be not only valuable for understanding wood formation in conifers. The enzymes might be also interesting tools for industrial use.

Totte NiittyläTotte Niittyla 1150, group leader at UPSC, is interested in the transport of carbohydrates from photosynthetic tissues to the wood and their metabolism in the wood. He and his team are developing carbon-13 isotope flux measurements for aspen. The researchers expose aspen plants for a short time to carbon dioxide that is labelled with the heavy isotope carbon-13. Then, they analyse how the label is transported to and metabolised in developing wood. By determining which compounds are labelled combined with enzyme activity measurements the researchers around Totte Niittylä aim to identify new genes that control carbon fluxes during wood formation.
