Other claims from this paper (9)
- Intervention effect Nitrate induced the formation of nitrate reductase activity in barley aleurone layers.
- Intervention effect Nitrate did not induce alpha-amylase synthesis in barley aleurone layers.
- Intervention effect Nitrate had no effect on gibberellic acid-induced alpha-amylase synthesis.
- Intervention effect Cycloheximide inhibited the nitrate-induced increase in nitrate reductase activity.
- Intervention effect 6-methylpurine inhibited the nitrate-induced increase in nitrate reductase activity.
- Intervention effect Actinomycin D did not inhibit the nitrate-induced increase in nitrate reductase activity.
- Intervention effect Abscisic acid had little or no direct effect on nitrate-induced nitrate reductase formation.
- Intervention effect Gibberellic acid interfered with nitrate reductase activity in long-term experiments (greater than 6 hr).
- Recommendation Barley aleurone layers are a convenient tissue for studying substrate- and hormone-induced enzyme formation.
