Carbon export from arbuscular mycorrhizal roots involves the translocation of carbohydrate as well as lipid

From: Plant Physiology | Date: March 1, 2003| Author: | Copyright information

Arbuscular mycorrhizal (AM) fungi take up photosynthetically fixed carbon from plant roots and translocate it to their external mycelium. Previous experiments have shown that fungal lipid synthesized from carbohydrate in the root is one form of exported carbon. In this study, an analysis of the labeling in storage and structural carbohydrates after ^sup 13^C^sub 1^ glucose was provided to AM roots shows that this is not the only pathway for the flow of carbon from the intraradical to the extraradical mycelium (ERM). Labeling patterns in glycogen, chitin, and trehalose during the development ...
