- They were imbibed in H2O or 20 mm H2O2 for 24 h, washed twice with H2O and placed in Petri dishes with two layers of filter paper moistened with H2O.
- Protein carbonylation is considered as a potent biomarker of oxidative stress, which can play regulatory roles, such as seed dormancy alleviation (El-Maarouf Bouteau et al. 2007) and salt-stress tolerance in leaves (Tanou et al. 2009).
- oxidative features such as protein carbonylation, endogenous H2O2 and lipid peroxidation levels
- H2O2 treatment of the pea seeds increased their endogenous H2O2 content and caused carbonylation of storage proteins and of several metabolic enzymes
- expression of one of them, PsMAPK2, largely increased upon pea seed imbibition in H2O2, whereas no change could be observed in expression of the other, PsMAPK3
