Abstract

The endogenous primary amino acid derivative N'-Trimethyl-L-Lysine (TML) induces resistance in bean plants against the biotrophic fungi Uromyces phaseoli. The effectiveness of protection depends on the interval between treatment and inoculation of the plants and on the dosage of applicated TML. It acts as resistance inducer within two concentration ranges of 10-3-10-5 and 10-8-10-10 mol/l, respectively, if applied 6 or 8 days after inoculation. [ABSTRACT FROM AUTHOR]

Abstract

Acidic extracts from TNV and AMV infected “Saxa” bean leaves were electrophoretically examined for protein content. In native conditions of resolution (PAGE) at least three protein bands (PS1–3) not present in the control were found. In denaturing conditions (SDS–PAGE) at least one (PSa), but often two or three such proteins (PSb, c) were found in the same extracts. Chromatographic resolution of proteins on Sephadex G-100 column resulted in partial purification of the PS-proteins. Additional, not known before, slow-migrating protein (PS0) induced by hypersensitive viral infection was discovered in some of the eluted fractions. Both PS0–3 and PSa–c proteins were present in the same fractions. This fact suggests their similarity in molecular weights and/or shapes.
