The effect of SO2 on the extractable activity of ATP sulfurylase (EC 2.7.7.4.). adenosine 5′-phosphosulfate sulfotransferase, ribulosebisphosphate carboxylase, chlorophyll, protein, sulfate, and amino acids was examined in leaves of potted grafts of beech (Fagus sylvatica L.) treated in outdoor fumigation chambers. Addition of 0.025 and 0.075 μl SO2 1−1 to unfiltered ambient air caused a decrease in the extractable activity of adenosine 5′-phosphosulfate sulfotransferase to about 20 to 30% of the controls. Neither the extractable activity of ATP sulfurylase and ribulosebisphosphate carboxylase nor the content in chlorophyll, total amino acids and protein were significantly affected by SO2, but there was an increase in the sulfate content. Leaves treated with 0.075 μl SO2 1−1 contained more alanine and cysteine and less serine than the controls. After transfer of the SO2-treated beech trees to control chambers there was an increase in adenosine 5′-phosphosulfate sulfotransferase activity, but no significant decrease in SO2−4-sulfur.
