The latter role is specific to the symbiotic nature of ECMs, in that the fungi associated with the fine roots can sometimes acquire C from the soil through enzymatic breakdown of organic matter especially during winter months when supplies of photosynthates from host plant are low or unavailable as well as from the tree photosynthates at a rate ...
