Other claims from this paper (8)
- Observation ATP sulfurylase activity peaked in leaves of approximately 7-day-old bean seedlings.
- Observation Adenosine 5-phosphosulfate sulfotransferase activity peaked at about 11 days.
- Observation Both enzyme activities declined during senescence and were nearly absent after 17 days.
- Association Sulfate incorporation into amino acids and protein followed the sulfotransferase activity time course.
- Observation Cysteine and sulfate decreased markedly during senescence.
- Observation Ribulosebisphosphate carboxylase activity peaked at 13 days.
- Observation About 40% of peak ribulosebisphosphate carboxylase activity remained after 17 days.
- Observation Assimilatory sulfate reduction stops before carbon dioxide and nitrate assimilation in primary bean leaves.
