Analysis of bean (Phaseolus vulgaris L.) proteins affected by copper stress

No significant difference was observed in the leaf protein pattern between controls and 15 μM Cu-treated plants. However, at 50 μM Cu exposure, the appearance of PvPR1 and a homologue of Arabidopsis thaliana thylakoid lumenal 17.4 kDa protein was observed. Another protein slightly enhanced by Cu treatment had sequence homology to a mitochondrial precursor of glycine cleavage system H protein of Flaveria pringlei.
