Abstract
Caldwell et al.1 and Murphy2 have shown that in wheat and oat plants infected with Puccinia triticina and P. coronata respectively, the amount of nitrogen, and of some other substances present, is greater than in uninfected plants. Gretschushnikoff3 found that the rust he studied exereted urea and ammonia, which, he suggested, were removed by the host, since no correlation was found between the severity of the infection and the amount of ammonia and urea in the extracts of the rusted leaves. These facts suggest that rusts may fix atmospheric nitrogen just as some other fungi are believed to do.
