Translocation in Mycelia

Part of the The Mycota book series (MYCOTA, volume 1)

Abstract

Translocation is the process by which nutrients are moved along fungal hyphae to other parts of the colony. Simple observations indicate that this is a necessary part of proper colony function. Thus, when mycelium is growing on agar, the concentration of glucose in the agar under the colony declines markedly as it moves from the margin towards the center (Robson et al. 1987). There must be translocation from the source of accumulation of nutrients at the margin through the hyphae to the center of the colony, if the latter is to function normally. Equally, any hyphae which extend into the air above a mycelium on the agar or other surface must have nutrients translocated through them in order that extension may take place.
