Infection Structures from Rust Urediospores: Effect of RNA and Protein Synthesis Inhibitors

Urediospores of Puccinia graminis tritici, floated on buffer, produce infection structures when subjected briefly to 30° C soon after germination. Inhibitors of RNA synthesis interfere with the differentiation of infection structures if present during this heat treatment. Inhibitors of protein synth...

Description
Summary:Urediospores of Puccinia graminis tritici, floated on buffer, produce infection structures when subjected briefly to 30° C soon after germination. Inhibitors of RNA synthesis interfere with the differentiation of infection structures if present during this heat treatment. Inhibitors of protein synthesis prevent differentiation if present following heat treatment. Apparently infection structure formation is accompanied by synthesis of RNA, and the completion of infection structure development requires protein synthesis.
