Infection of leaves of Tussilago by Puccinia poarum results in decreased export of photosynthetic products and, when infection is severe, in increased import. Photosynthetic products move to infection sites where host metabolites are converted to specific fungal products, including mannitol, arabitol, trehalose, glycogen, glucomannan and lipids. More previously fixed 14C is translocated to the fungus in the dark than in the light since, in the dark, degradation of starch contributes to net movement of 14C.
