Acquisition, assimilation and transport of nutrients and carbon in mycorrhizal symbioses
Well-functioning mycorrhizae are established and maintained on condition of mutual nutrient exchange. Understanding the nutrients for photosynthesis-derived sugar trade has been a challenge and source of debate for ages. This session will focus on the physiological and molecular-genetic mechanisms by which mycorrhizal fungi regulate homeostasis of macro-, micronutrients and sugars, determine the nutrient offer at the plant-fungal interface and impact on nutrient balances of the host plant. Nutrient foraging, assimilation, storage, translocation, transfer, metabolism and their regulation in distinct external conditions as well as interspecific differences, specialization and adaptation towards particular environments are included.
