Summary

Rusted wheat leaves were incubated simultaneously with alanine-1-14C and glucose-6-T. Uredospores formed during the application of the tracers were collected and the bound alanine was isolated from the spores and the host tissue. Comparison of the 14C/T ratio of spore-alanine and host-alanine indicates that the mycelium not only withdraws alanine from the host but in addition carries out an alanine synthesis on its own. This alanine is synthesized from glucose which the mycelium takes up from the host.
