Abstract

THE intracellular haustoria of rust (P. graminis tritici Erikss. and Henn.) and mildew (E. graminis hordei Marchal) are usually regarded as absorbing organs, which, in the case of rust at least1, only invaginate the protoplasts of the host cells. The use of radioactive tracers has shown that phosphate2,3, sugars and products of carbon dioxide fixation3 accumulate in infections of these obligate parasites, and the suggestion has been made that the pathogens require phosphorylated intermediates of host metabolism4.
