Climate change could affect symbiotic relationships between microorganisms and trees

Some fungi and bacteria live in symbiosis with tree roots in forest soil to obtain mutual benefits. The microorganisms help trees access water and nutrients from the atmosphere or soil, sequester carbon, and withstand the effects of climate change. In exchange, they receive carbohydrates, which are essential to their development and are produced by the trees during photosynthesis.  More than 200 scientists from several countries, including 14 from Brazil, collaborated to map the global distribution of these root symbioses and further the understanding of their vital role in forest ecosystems. They identified factors that determine where different kinds of symbionts may emerge and estimated the impact of climate change on tree-root symbiotic relationships and hence on forest growth.  Read more....
