Abstract

Exposure of Chinese cabbage (Brassica pekinensis) to an enhanced Cu2+ level (4 μM) resulted in a reduced plant biomass production and an increased shoot to root ratio at both sulfate-sufficient and sulfate-deprived conditions. However, sulfate deprivation had a more rapid negative effect on plant biomass production than an enhanced Cu2+ level, The expression and activity of the sulfate transporters and the expression of APS reductase in Chinese cabbage were rapidly up-regulated (already after 1 or 2 days) upon exposure to 4 μM Cu2+, sulfate deprivation and their combination. Though the impact of sulfate deprivation on the expression and activity of the sulfate transporters was hardly further affected by Cu2+.
