Plant defense response is an elaborate biochemical process shown to depend on the plant genetic background and on the biological stressor. This work evaluated the soybean biochemical foliar response to brown stink bug herbivory injury through an analysis of redox metabolism and proteomic 2DE profiles of susceptible (BRS Silvania RR) and resistant (IAC-100) varieties. The activity of lipoxygenas...

Transgenerational transmission of information about stress exposure is manifested as an increase in the somatic homologous recombination frequency in plants. Our aim was to investigate whether information about changes of antioxidative enzyme activities and protein HSP70 induction are also transmitted in response to stress caused by UV-C irradiation. These stress indicators were investigated in...

Sensitivity of common onion (Allium cepa L.) and faba bean (Vicia faba L.) to cadmium (Cd) stress was investigated using genotoxicity endpoints. Simultaneously, the antioxidative stress enzymes (guaiacol peroxidise and catalase) and lipid peroxidation [malonaldehyde (MDA) content] were investigated in the plants exposed to Cd in solution. The endpoints screened for genotoxicity included chromos...
