NORWAY SPRUCE FINE ROOTS
Temporally resolved transcriptomic analysis of Norway spruce (Picea abies) fine roots grown in nutrient-deficient and nutrient-enriched forest plots in the boreal region of Northern Sweden.
Extended Data Figure 1. Climatic and phenological metadata for the Flakaliden research site (64°07′N, 19°27′E, altitude 310–320 m). (A) Location and layout of the Flakaliden research site. (B) Air and soil temperature (soil temperatures recorded at Svartberget field research station (64°14′N, 19°34′E), in 2011), and precipitation recorded at Flakaliden in 2011. (C) Radiation and relative humidity recorded at Flakaliden in 2011. (D) Day length at Flakaliden in 2011. (E) Phenological milestones of Norway spruce grown at Flakaliden. (F) Cumulative length production and mortality of spruce roots (mm tube-1) in the mineral soil layer at Flakaliden. A green line indicates nutrient limited soil; a gold line indicates nutrient enriched soil. Modified from Majdi and Andersson, 2005. (G) Soil CO2 efflux (gCO2- cm-2 h-1) at Flakaliden. A green line indicates nutrient limited soil; a gold line indicates nutrient enriched soil. Modified from Olsson et al., 2005. (H) Tree height (m), aboveground biomass (kg tree-1) and belowground biomass (g m-2) of nutrient limited and nutrient enriched Norway spruce (Sigurdsson et al. 2013; Majdi and Andersson, 2005).
I am a Researcher working at the Department of Forest Genetics and Plant Physiology, SLU.
I obtained my PhD from the University of Western Australia and have been working at the Umeå Plant
Science Centre for the past 4 years. Currently, I am using molecular techniques to describe the impact of
seasonality and soil nutrient alteration on the ectomycorrhizal association between Norway spruce and
fungal communities of the northern boreal forests of Sweden.
Biologist and computer engineer working as bioinformatician at the Department of Forest Genetics and Plant Physiology, SLU.
My goal is to apply machine learning to biology and to develop tools that help scientists get faster and reliable experimental results.
I am a PhD student at the Umeå Plant Science Centre. I am studying fungi and bacteria in the Swedish forest,
and how these microbial lifeforms are influenced by factors such as nitrogen addition and modern forestry practices.
Targeted field experiments in combination with sequencing and chemical analysis methods allow us to assess these
microbial communities under different conditions. As we learn more about microbial communities and the role they
play in the forest, it will enable us to involve microbial life forms into planning of more efficient and sustainable
I’m a plant physiologist and ecophysiologist. I work as a postdoc at the Dept. of Forest Ecology and
Management (SLU) and I defended my PhD in 2017 at Umeå University. Currently I’m working on characterising
the diurnal and seasonal dynamics of mesophyll conductance and the balance between the carbon and water
cycle in various boreal tree species, using mostly stable isotope techniques. During the PhD I was working
on plant acclimation to different growth temperatures in combination with low nitrogen availability or elevated CO2.
I’m an ecologist interested in how plants interact with their environment. During my master,
I studied how plants change their biochemistry and physiology in response to drought stress. Currently,
I’m doing my PhD, applying molecular biology to study the response of seedlings to fertilization and the
impact of the fertilization on the plant-microbiome interactions.
My expertise is in the field of metagenomics. I develop and run workflows and tools to study microbial populations.
I have a passion for trees and am interested in how phenotypic variation among individuals is determined
by genome variation. My research focuses heavily on gene expression variation and the use of high throughput
sequencing methods. This has led us to dedicating time to web resource development to offer access to the data
resources developed and, most recently, to exploring the fascinating relationships between trees and their
