Root proteome response to growth on tannery waste in three different poplar species with various adaptation abilities
Institute of Dendrology, Polish Academy of Sciences, Parkowa 5, 62-035 Kórnik, POLAND
In our study we compared growth of three poplar clones (Populus tremula ×alba, P. alba ‘Villafranca” and P. nigra) on chromium-containing solid tannery waste. Tolerance index of saplings ranged from only 25% for P. nigra up to 80% for P. tremula x alba. Standard morphological, chemical and biochemical analyses also confirmed significant differences in reaction of all tested clones to such growth conditions. Preliminary proteomic study showed an unequal level of changes in protein profiles from roots in different poplars.
