- Intervention effect Cadmium reduced biomass accumulation in leaves and roots after one week.
- Intervention effect Cadmium decreased photosynthetic activity.
- Intervention effect Cadmium significantly decreased nitrate content.
- Intervention effect Cadmium inhibited nitrate reductase and nitrite reductase activities.
- Observation NADH-glutamate synthase and NADH-glutamate dehydrogenase activities increased.
- Observation Ammonium accumulated in treated tissues.
- Observation Total protein decreased in treated plants.
- Observation Amino acids accumulated in treated plants.
- Observation Gln was the major amino acid in xylem sap of treated and control plants.
- Intervention effect Cadmium increased total amino acid content in phloem.
- Intervention effect Cadmium maintained phloem Gln/Glu ratios.
- Intervention effect Cadmium decreased chloroplastic GS protein and mRNA.
- Intervention effect Cadmium increased cytosolic GS and glutamate dehydrogenase transcripts and proteins.
- Observation Asparagine synthetase mRNA increased in roots.
- Observation Asparagine increased strongly in roots.
