Mechanisms of Differential Resource Uptake and Translocation in Agaricus bisporus.

ABSTRACT: Mushroom-forming fungi form interconnected networks of hyphae and cords that cooperate to colonise their environment and feed developing mushrooms. To fully enable this cooperation, transport across the network is essential for the collection and delivery of resources when and where needed. It is not known to what extent, and with which resources, specific parts of the network contribute to feeding the developing mycelium and mushrooms. In this study, we investigated the translocation patterns of water, carbon and nitrogen in Agaricus bisporus, using stable isotope tracers. Ammonium-derived ¹⁵N, but not glucose-derived ¹³C, was consistently transported from the centre to the periphery of colonies in axenic culturing conditions. External wicking along the hyphae is lik
