In autumn, the trees get their autumn colors and finally shed their leaves but how do the trees know that the autumn is coming? Professor Stefan Jansson, Umeå University, explains how the tree's calendar works and why the leaves change their color in autumn. The lecture is held in Swedish.

Sacha Escamez, postdoctoral researcher at UPSC, Umeå University, describes how plants utilize some of their cells to build pipe-like structures. These structures allow them to draw water and nutrients from the soil in order to distribute it throughout their bodies. The lecture is held in English with Swedish subtitles.

Per Gardeström, Professor at Umeå University, explains how carbon dioxide is fixed during photosynthesis with the help of sun light. He focusses on the collaboration between chloroplasts and mitochondria. Both are plant cell compartments that are important for the energy supply of the cell. The lecture is held in Swedish.

How is information and material exchanged between different compartments within a plant cell? Anirban Baral, postdoctoral researcher at UPSC, Swedish University of Agricultural Sciences, explains how the traffic in plant cells is organised. The lecture is held in English with Swedish subtitles.

Siamsa Doyle, researcher at UPSC, Swedish University of Agricultural Sciences, describes why and how they use chemicals to block proteins that control plant functions. She explains that the effects of such chemicals tell a lot about the blocked proteins and their roles in plant growth and development. Like this, they can use chemicals to virtually “dissect” plants. The lecture is held in English with Swedish subtitles.

Judith Felten, group leader at UPSC and Assistant Professor at the Swedish University of Agricultural Sciences, talks about the knowns and unknowns of the fascinating mechanism that allows roots and fungi to form a beneficial relationship (symbiosis). The fungus provides soil-nutrients to the tree and receives photosynthetic sugars from the tree. Like this both partners benefit from each other and stimulate each other’s growth. The lecture is held in English with Swedish subtitles.

Benedicte Albrectsen, researcher UPSC, Umeå University, speaks about how plants defend themselves with the help of chemical substances. She focusses on a special class of substances, the so called phenols, and explains how her research group analyses them. The lecture is held in Swedish.

How can old field trials be of use in modern forest genetics? Anders Fries, researcher in forest genetics, Swedish University of Agricultural Sciences, describes what old field trials have taught them e.g. about wood properties and what they learned from molecular genetic studies in these old trials. The lecture is held in Swedish.
