Researchers Discover Novel Molecular Mechanism That Enables Conifers to Adapt to Winter

18.08.2020

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. 

Shared Threat Prompts Communication between Plants

04.10.2019

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.

Amazonian Soils Mapped Using Indicator Species

17.04.2019

Understanding the ecology and distributions of species in Amazonia is hampered by lack of information about environmental conditions, such as soils. Plant occurrence data are typically more abundant than soil samples in poorly known areas, and researchers from Finland and Brazil have now developed a method that uses both plant and soil data to produce a map of soil properties.
