Abstracts |
Ectomycorrhizal (ECM) fungi receive photosynthetically fixed carbon from the host tree and, in return, supply nutrients such as phosphorus (P) and nitrogen (N) from the soil. An ECM symbiosis system in a two-dimensional, soil-free rhizobox was developed to visualize nutrient translocation during ECM symbioses using a digital, time-course autoradiographic technique with imaging plates. Several studies using 14C and 33P radioisotope tracing experiments are discussed to demonstrate the translocation of 33P-phosphoric acid and photosynthetically fixed carbon between fungi and host trees and between mycelia via mycelia anastomosis. Additionally, novel techniques that can visualize nutrient translocation during mycorrhizal symbioses are discussed. |
