AMINO ACID COMPOSITION OF UREDOSPORES OF PUCCINIA GRAMINIS VAR. TRITICI

Abstract

Uredospores of Puccinia graminis var. tritici (Race 56) were analyzed quantitatively for total free amino acids and ninhydrin-positive substances by ion-exchange chromatography. Extracts of these substances were obtained by leaching the spores and by re-extracting leached spores with boiling water. Thirty-five ninhydrin-positive compounds were found and identified. The leach extract differed quantitatively from the boiled extract although both contained the same 35 substances. It is proposed that the spores contain ninhydrin- positive substances coating the spore wall that are easily extracted and other ninhydrin-positive substances in the protoplasm that can be extracted only with difficulty.
