Abstract
The effects of lead, copper, sodium nitrite and indolo 3-acetic acid (IAA) on growth and protein patterns of roots of Lupinus luteus were investigated. All tested compounds affected root development inhibiting growth and causing thickening. Analysis of polypeptide patterns by SDS-polyacrylamide gel electrophoresis revealed that in the presence of heavy metal ions and NaNO2, an increased accumulation of a 16 × 103 Mr polypeptide occurred. However, the increased quantity of this component cannot be directly connected with root growth limiting factors as it has not been found among polypeptides from IAA-treated roots. We postulate that the 16 × 103 Mr polypeptide belongs to a group of non-specific stress proteins, which accumulate in the presence of toxic substances. © 1994.
