Little Cross-Feeding of the Mycorrhizal Networks Shared Between C₃-Panicum bisulcatum and C₄-Panicum maximum Under Different Temperature Regimes.

ABSTRACT: Common mycorrhizal networks (CMNs) formed by arbuscular mycorrhizal fungi (AMF) interconnect plants of the same and/or different species, redistributing nutrients and draining carbon (C) from the different plant partners at different rates. Here, we conducted a plant co-existence (intercropping) experiment testing the role of AMF in resource sharing and exploitation by simplified plant communities composed of two congeneric grass species (Panicum spp.) with different photosynthetic metabolism types (C₃ or C₄). The grasses had spatially separated rooting zones, conjoined through a root-free (but AMF-accessible) zone added with ¹⁵N-labeled plant (clover) residues. The plants were grown under two different temperature regimes: high temperature (36/32°C
