The floating university is exploring the possibility of growing crops in the Arctic.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. In August, a new expedition of the Arctic floating university started, which received a record number of applications. Now the summing up is going on.

The expedition of the Arctic Floating University on the scientific expedition ship Mikhail Somov started in the port of Dixon, passed through the Franz Josef Land archipelago, which includes Hooker and Graham Bell islands, Wilczek Land and Hayes Island, and ended in Arhangelsk. The scientific trip was organized by the Northern (Arctic) Federal University named after M.V. Lomonosov with the support of Rosneft.

In Taimyr, with a short polar summer, the flora begins to bloom when the snow has not yet melted

One of the scientists participating in the study, a researcher at the RAS Plant Physiology Institute named after K.A. Timiryazev Alexander Tyurin was looking for lipid metabolism enzymes for specific photosynthetic organisms in the Arctic.

During field landings, the scientist collected tissue samples of vascular plants, mosses, lichens, cyanobacteria on land and phytoplankton in the waters. Alexander plans to isolate mRNA from fixed samples, obtain cDNA and prepare cDNA libraries for sequencing. Thanks to modern technology, the collection of samples was carried out in a gentle manner, writes.

In his scientific activity, Alexander is engaged in the study of plants and bacteria that have adapted to the most severe conditions of the polar regions. From the point of view of creating cold-resistant agricultural crops, its activity is a promising direction: as a result, we can talk about microorganisms that are active in the conditions of the polar climatic zone and space.

Earlier, we reported that Canadian scientists found giant viruses in an Arctic lake, and the warming of the Arctic waters contributes to fishing.
