Researchers from the University of Padua in Italy found a juniper at Utsjoki in Finnish Lapland, which they analysed to be 1,647 years old by examining the annual rings.
Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Researchers inoculated oilseed rape plants with a species of fungus that is known for its ability to combat pest insects. Utilising the relationship between beneficial fungi and crop plants may introduce a new era of agriculture where the plant resilience is improved and the ecological footprint of traditional/chemical pesticides is minimised.
Glyphosate, a widely-used chemical compound in herbicides and its wide-ranging impacts on ecosystems and pollinators will be the research focus at the University of Turku. In their proposals, the researchers highlight the importance of comprehensively understanding the problem and stress the significance of collaboration between researchers, farmers and decision-makers to address the issue effectively. The research has received significant funding from the Research Council of Finland and Sakari Alhopuro Foundation.

Soil microbes can have a great impact on the spread of harmful invasive species as they can either hinder or facilitate the plant’s growth. Researchers at the Department of Biology of the University of Turku, Finland, studied the role of soil microbiota in the success of garden lupine, which is an invasive species in the Finnish nature.
A new study finds that glyphosate residues in soil affect phytohormones in aboveground plant parts. Academy of Finland funded postdoctoral researcher Dr. Benjamin Fuchs investigates the effects of herbicide residues in soil on plant physiology and chemical ecology of plant-insect interactions.
Scientists from University of Turku observed that ergot, a common plant disease on rye, defended its host plant chemically against grass feeding insects. The ergot disease in grains spoils the yield and causes seed loss to the plant. Based on this, it is classified as harmful from the human perspective. A new study states that the ergot appears to be a beneficial protector for its host plant capable of even increasing plant fitness.
Photosynthesis in conifer forests is one of the most important carbon sinks on a global scale. Unlike broadleaf trees, conifers are evergreen and retain their photosynthesis structure throughout the year. Especially in late winter, the combination of freezing temperatures and high light intensity exposes the needles to oxidative damage that could lead to the destruction of molecules and cell structures that contribute to photosynthesis. Researchers from the University of Turku have discovered a previously unknown mechanism that enables spruce trees to adapt to winter.
New study by the University of Turku and Cornell University shows that long-term elimination of herbivorous insects from plants changes the way they communicate with each other. The study focused on Solidago altissima, i.e. tall goldenrod, and indicated that communicating about threats also benefits the plant sharing the information. Different communication strategies between plants can be explained with the differences in the volatile organic compounds the plants release.
